What Is SSMUH?
Small Scale Multi-Unit Housing (SSMUH) is British Columbia's provincial framework for allowing gentle density on residential lots that were previously restricted to a single detached house. Introduced under Bill 44 (the Housing Statutes Amendment Act), SSMUH requires every municipality in BC to update its zoning bylaws to permit multiple housing units on single-family and duplex-zoned lots, without requiring the property owner to go through a rezoning process. In Greater Victoria, this means most residential lots now permit 3 to 6 units by right — no public hearing, no rezoning, no discretionary approval required.
The practical effect is significant: if you own a single-family lot in Greater Victoria, you likely have the right to build a secondary suite, a garden suite, a duplex, a triplex, or even a fourplex, depending on your lot size and location. This represents the most substantial change to residential zoning in BC history.
SSMUH is not a single building type. It is a category of housing that includes secondary suites (basement or in-home suites), detached garden suites (also called laneway houses, carriage houses, or backyard cottages), duplexes, triplexes, fourplexes, and in some cases townhouse-style configurations. The term “small scale” distinguishes these projects from larger apartment buildings, which fall under different zoning and development frameworks.
How Bill 44 Changed the Rules
Before Bill 44 received Royal Assent in November 2023, building anything beyond a single-family home on a residentially-zoned lot in most Greater Victoria municipalities required a rezoning application. Rezoning meant public hearings, neighbourhood consultation, months (or years) of processing, and no guarantee of approval. This created a de facto barrier to gentle density, even when market demand and municipal housing targets called for more supply.
Bill 44 changed this by requiring municipalities to pre-zone for SSMUH. The key provisions include:
- Municipalities must allow at least one secondary suite or one additional dwelling unit on all single-family zoned lots.
- Lots under 280 square metres must permit up to three units.
- Lots of 280 square metres or more must permit up to four units.
- Lots near frequent transit stops (within 400 metres) may permit up to six units.
- Municipalities cannot require a public hearing or rezoning for projects that comply with SSMUH standards.
- Municipalities may still regulate building form, setbacks, height, and lot coverage, but they cannot use those regulations to effectively prohibit the permitted number of units.
The legislation also required municipalities within urban containment boundaries to update their Official Community Plans (OCPs) and zoning bylaws by June 30, 2024. Some municipalities met this deadline; others are still refining their bylaws, but the provincial framework applies regardless.
Bill 25 Update (November 2025): What Changed
New compliance deadline: June 30, 2026
All affected municipalities must update their zoning bylaws to comply with Bill 25 by June 30, 2026. This includes Victoria, Saanich, Langford, Oak Bay, Colwood, View Royal, Esquimalt, Central Saanich, and North Saanich.
In November 2025, the BC Legislature passed Bill 25 — the Housing and Municipal Affairs Statutes Amendment Act — which clarified and tightened the original Bill 44 SSMUH framework. Two changes directly affect Vancouver Island property owners:
1. Restricted zone redefined
Under the original Bill 44, some municipalities argued that lots already allowing three units (a principal dwelling plus secondary suite plus coach house) were exempt from the full SSMUH density requirements. Bill 25 closed this loophole. The definition of a “restricted zone” now includes any zone that permits a single detached home with a secondary suite and detached accessory dwelling unit. These lots must now permit the full 4–6 unit density required under SSMUH — not just three.
2. June 30, 2026 compliance deadline
Municipalities that had not fully updated their zoning bylaws under Bill 44 — or whose bylaws used the old “three unit” interpretation — must now comply with the updated requirements by June 30, 2026. The provincial framework applies regardless of whether your municipality has passed updated bylaws. If a municipality misses the deadline, the province can impose a ministerial order overriding local zoning.
What You Can Build (by Lot Size)
The number of units you can build depends primarily on your lot area. Here is a general breakdown based on the provincial framework:
Small lots (under 280 m²)
On lots smaller than 280 square metres, you are entitled to at least one secondary suite in addition to the primary dwelling. This could be a basement suite, an above-garage suite, or another in-home suite configuration. Garden suites may not be feasible on very small lots due to setback and lot coverage constraints.
Standard lots (280 m² and above)
This is where most Greater Victoria lots fall. On lots of 280 square metres or more, you can build up to four housing units. Common configurations include:
- A fourplex (4 units in one building).
- A triplex with a garden suite.
- A single-family home with a secondary suite and a detached garden suite, plus an additional unit.
- Two duplexes (where municipal bylaws allow).
The specific form, whether you attach or detach the units, is governed by municipal bylaws, which vary. Some municipalities are more permissive about detached configurations; others prefer attached buildings to manage site coverage.
Near frequent transit (280 m²+)
Lots of 280 square metres or more that are within 400 metres of a frequent transit stop may qualify for up to six units. This higher density tier is designed to concentrate housing near the transit infrastructure that supports it. Options include:
- A sixplex (6 units in one building).
- A fourplex with two garden suites.
- Multiple smaller buildings totalling six units (where municipal bylaws allow).
Large lots near designated transit exchanges may qualify for even higher density under Bill 47 (TOA legislation), which is a separate framework allowing mid-rise buildings of up to 10 storeys.
To understand your specific development potential, it is important to know your exact lot size, current zoning designation, and location relative to transit corridors and municipal boundaries.

Check Your LotMunicipality-Specific Rules
While Bill 44 sets the floor for what municipalities must allow, each municipality in Greater Victoria has adopted its own specific bylaws, design guidelines, and development standards. Here is an overview of the major municipalities:
City of Victoria
Victoria was among the first municipalities in BC to embrace gentle density, and its SSMUH implementation reflects years of policy groundwork. The city adopted its updated zoning bylaws ahead of the June 2024 provincial deadline, building on its existing Missing Middle Housing Initiative that had already introduced houseplex zoning in several neighbourhoods.
Under Victoria's current bylaws, houseplexes of up to six units are permitted on lots in the Traditional Residential (R1-B) and related zones, particularly near village centres and major corridors identified in the Official Community Plan. On standard residential lots of 280 square metres or more (most Victoria lots are 550 to 700 square metres), up to four units are permitted as of right under the provincial SSMUH framework. On lots under 280 square metres, up to three units are permitted. Lots near frequent transit stops may qualify for up to six units.
Garden suites in Victoria may be up to 70 square metres in floor area, with a maximum height of 7.6 metres (two storeys). Side and rear setbacks for garden suites are reduced to 1.5 metres, making them feasible on narrower lots. The city does not require the property owner to live on-site, which means both the principal dwelling and the garden suite can be rented.
Victoria offers free pre-application consultations for SSMUH projects and has published design guides with pre-approved floor plans for garden suites. Building permit processing for straightforward SSMUH applications typically takes 8 to 12 weeks. The city has waived public notification requirements for SSMUH projects that comply with the zoning bylaw.
- Development Cost Charges (DCCs) apply per new unit, typically $10,000 to $15,000 depending on the area and unit type.
- Heritage Conservation Areas (such as parts of Fernwood, James Bay, and Gonzales) may impose additional design review for exterior alterations visible from the street.
- Properties within 400 metres of a frequent transit route may have reduced or eliminated parking requirements under the city's parking bylaw.
- Victoria's lot coverage maximums range from 40% to 50% depending on the zone, which can constrain footprint options on smaller lots.
District of Saanich
Saanich is the largest municipality by land area in the Capital Regional District and contains a wide variety of lot sizes, from compact urban lots in Quadra-Hillside to multi-acre rural properties in Prospect Lake and Cordova Bay. The district adopted its SSMUH zoning amendments in alignment with Bill 44 requirements, permitting up to four units on residential lots of 280 square metres or more, and up to three units on lots under 280 square metres. Properties near frequent transit stops along corridors such as Douglas Street, Quadra Street, and Shelbourne Street may qualify for up to six units on lots of 280 square metres or more.
Garden suites in Saanich are permitted up to 90 square metres in floor area, with a maximum building height of 7.5 metres (two storeys). Minimum setbacks are 1.5 metres from side and rear lot lines, though lots adjacent to Agricultural Land Reserve (ALR) parcels may require larger buffers. Saanich requires that the garden suite be architecturally compatible with the existing neighbourhood character, which in practice means review of rooflines, exterior cladding, and window placement.
Sewer servicing is a critical consideration in Saanich. The municipality is divided into sewered and unsewered areas. In sewered areas, all new dwelling units must connect to the municipal sewer system. In unsewered areas (parts of Gordon Head, Broadmead, Cadboro Bay, and rural Saanich), additional units may require an upgraded septic system or connection to the nearest sewer main, which can add $30,000 to $80,000 to project costs depending on distance and terrain.
Saanich's building permit processing times for SSMUH projects average 10 to 14 weeks. The district requires a geotechnical report for lots with slopes exceeding 20%, which affects many properties in areas like Mount Tolmie, Mount Douglas, and Christmas Hill. Development Cost Charges in Saanich are assessed per additional unit and vary by DCC area, ranging from approximately $12,000 to $20,000 per unit. The district also requires tree protection plans where significant trees exist on the development site.
City of Langford
Langford has consistently been one of the most development-friendly municipalities in the Capital Regional District. The city had already permitted secondary suites and garden suites on most residential lots before Bill 44, and its SSMUH bylaw updates were adopted swiftly. Langford's approach prioritizes housing supply and streamlined approvals, making it one of the easiest jurisdictions in Greater Victoria for SSMUH projects.
On standard residential lots of 280 square metres or more (most fall between 500 and 800 square metres), Langford permits up to four units as of right under SSMUH. On lots under 280 square metres, up to three units are permitted. In areas adjacent to the Westshore Town Centre and near the Langford bus exchange, properties on lots of 280 square metres or more may also qualify for higher density under Transit-Oriented Area (TOA) provisions, which can permit up to six units depending on lot size and proximity to the transit hub.
Garden suites in Langford are permitted up to 90 square metres, with a maximum height of 7.5 metres. Minimum setbacks are 1.5 metres from side and rear property lines. The city does not impose owner-occupancy requirements, allowing both the primary dwelling and garden suite to be rented. Langford also permits secondary suites in conjunction with garden suites on lots that meet the unit count thresholds.
Langford's building permit turnaround is among the fastest in the region, with straightforward SSMUH applications typically processed in 6 to 10 weeks. The city's Development Cost Charges are structured to encourage SSMUH, with DCCs for secondary suites and garden suites set lower than for principal dwelling units. Typical DCCs range from $8,000 to $14,000 per additional unit.
- Langford requires all new units to connect to municipal water and sewer. The city is fully serviced, so septic conversion is not typically an issue.
- Properties near Bear Mountain and in the Highlands border area may have steeper terrain requiring geotechnical reports.
- Langford does not impose heritage design review requirements, giving homeowners more flexibility in architectural style.
- The city has published template designs for garden suites that can expedite the design and approval process.
City of Colwood
Colwood adopted its SSMUH zoning amendments in compliance with the provincial Bill 44 timeline. The city permits up to four units on residential lots of 280 square metres or more, and up to three units on lots under 280 square metres, consistent with the provincial framework.
Garden suites in Colwood are permitted up to 80 square metres in floor area, with a maximum height of 7.5 metres. The city requires a minimum 1.5-metre setback from side and rear lot lines and requires that garden suites have a separate entrance that does not face the front street unless no other practical orientation exists. Secondary suites must also have a dedicated entrance separate from the principal dwelling's main entrance.
Colwood has its own designated transit exchange under TOA legislation, and properties within 400 metres also fall within the Transit-Oriented Area catchment. Properties within 200 metres of the Colwood Exchange may qualify for up to 10 storeys, and properties between 200 and 400 metres may qualify for up to 6 storeys. Homeowners near Colwood Corners, Royal Bay, and areas along the Galloping Goose Trail corridor should verify their TOA status with the city's planning department, as this can significantly affect what is buildable.
The city requires all new dwelling units to connect to municipal sewer and water services. Most of Colwood is fully serviced, though some older properties in the Wishart and Hatley Park areas may require sewer connection upgrades. Development Cost Charges in Colwood typically range from $10,000 to $16,000 per additional unit. Building permit processing for SSMUH applications averages 10 to 14 weeks.
- Colwood's design guidelines require that new construction be visually compatible with the existing streetscape, though the standards are less prescriptive than those in Oak Bay or Victoria's heritage areas.
- Royal Roads University lands and adjacent properties may have environmental development permit area restrictions that affect buildable area.
- The city has identified Colwood Corners as a priority growth area, and SSMUH projects in this vicinity may benefit from faster processing.
Township of Esquimalt
Esquimalt adopted its SSMUH bylaw amendments to comply with Bill 44, permitting up to four units on residential lots of 280 square metres or more, and up to three units on lots under 280 square metres. The township's compact geography and predominantly urban character make most residential lots eligible for SSMUH development. Properties within 400 metres of a frequent transit bus stop (service every 15 minutes) on lots of 280 square metres or more may qualify for up to six units. Check with Esquimalt's planning department to confirm which bus stops qualify as frequent transit under the provincial framework.
Garden suites in Esquimalt are permitted up to 75 square metres in floor area, with a maximum height of 7.5 metres (two storeys). Minimum setbacks are 1.5 metres from side and rear lot lines, and the township requires that garden suites maintain a minimum 3-metre separation from the principal dwelling to satisfy fire code requirements. Lot coverage maximums in Esquimalt's residential zones typically range from 40% to 45%, which can limit footprint options on smaller lots (many Esquimalt lots are 500 to 600 square metres).
Esquimalt has introduced a simplified permitting pathway for SSMUH projects that use pre-approved design templates. These templates cover common garden suite and secondary suite configurations and can reduce permit review times from the standard 10 to 14 weeks to approximately 6 to 8 weeks. The township encourages pre-application meetings with the planning department, which are available at no cost.
The township is fully serviced by municipal water and sewer, so septic systems are not a factor. Development Cost Charges are assessed per additional unit, typically in the range of $10,000 to $14,000. Esquimalt's design guidelines address building massing, roof pitch, and exterior materials to ensure new construction is compatible with the existing neighbourhood character, particularly in the heritage-rich areas around Old Esquimalt and Saxe Point.
- Properties near CFB Esquimalt and the naval dockyard may be subject to federal land use considerations that do not apply to typical residential lots.
- Esquimalt does not have a designated Transit-Oriented Area under Bill 47, but properties near frequent transit bus stops may qualify for the six-unit SSMUH allowance. The E&N Rail Trail corridor provides good cycling and pedestrian connectivity.
- Most lots in Esquimalt are above the 280 square metre threshold, making four-unit development widely eligible across the township.
District of Oak Bay
Oak Bay implemented its SSMUH bylaws as required under Bill 44, permitting secondary suites and garden suites on residential lots. The district has taken a measured approach to SSMUH, placing significant emphasis on design standards that maintain the established character of Oak Bay's neighbourhoods, which are among the most architecturally distinct in Greater Victoria.
On standard residential lots (many in Oak Bay are 600 to 900 square metres), up to four units are permitted under SSMUH since these lots exceed the 280 square metre threshold. On lots under 280 square metres, up to three units are permitted. Properties within 400 metres of a frequent transit bus stop (service every 15 minutes) on lots of 280 square metres or more may qualify for up to six units under SSMUH, though Oak Bay has limited frequent transit service compared to more central municipalities. Garden suites are permitted up to 70 square metres in floor area, with a maximum height of 7.5 metres. The district requires minimum setbacks of 2.0 metres from side lot lines and 2.5 metres from the rear lot line, which are slightly more restrictive than some neighbouring municipalities.
Oak Bay's design guidelines for SSMUH projects are among the most detailed in the region. The district requires that new construction, including garden suites, be compatible with the architectural character of the surrounding neighbourhood. This includes requirements for roof pitch, exterior cladding materials (wood siding, stone, or stucco are preferred; vinyl siding is discouraged), window proportions, and landscape screening. Properties in the Uplands area are subject to additional restrictive covenants that predate municipal zoning and may further constrain what can be built.
Building permit processing in Oak Bay for SSMUH applications typically takes 12 to 16 weeks due to the design review component. The district processes all SSMUH applications through its standard building permit pathway and does not currently offer pre-approved design templates. Development Cost Charges range from approximately $12,000 to $18,000 per additional unit.
- Oak Bay is fully serviced by municipal sewer and water.
- Significant tree protection bylaws apply, and removal of mature Garry oak trees requires special approval.
- Oak Bay does not have a designated Transit-Oriented Area under Bill 47. Some properties near the Oak Bay Avenue corridor may be within 400 metres of frequent transit bus stops, which could qualify them for the six-unit SSMUH allowance.
- The Uplands neighbourhood has heritage landscape covenants registered on title that may limit building placement and tree removal beyond what the zoning bylaw requires.
- Parking requirements in Oak Bay are one off-street space per dwelling unit, with no exemptions for transit proximity.
Town of View Royal
View Royal adopted its SSMUH bylaw amendments to comply with Bill 44, permitting up to four units on residential lots of 280 square metres or more, and up to three units on lots under 280 square metres. Properties within 400 metres of a frequent transit bus stop (service every 15 minutes) on lots of 280 square metres or more may qualify for up to six units under SSMUH. View Royal's geography includes both urban areas along the Old Island Highway corridor and more rural, sloped terrain near Thetis Lake and the Highlands border.
Garden suites in View Royal are permitted up to 80 square metres in floor area, with a maximum height of 7.5 metres and minimum setbacks of 1.5 metres from side and rear lot lines. The town requires that garden suites maintain a minimum 3-metre separation from the principal dwelling. On lots with significant grade changes, the town may require stepped foundations or retaining walls, which adds to construction costs.
Servicing is a key consideration in View Royal. While most of the urban core along the highway corridor is connected to municipal sewer, some properties in the western and northern parts of the town remain on septic systems. New dwelling units on unsewered lots must either connect to the nearest sewer main or demonstrate that the existing septic system can handle additional capacity, which typically requires a septic assessment by a registered onsite wastewater practitioner. Sewer connection costs in View Royal can range from $25,000 to $60,000 depending on distance and terrain.
View Royal requires geotechnical assessments on lots with slopes exceeding 15%, which affects a significant number of properties. Building permit processing for SSMUH projects averages 10 to 14 weeks. Development Cost Charges are assessed per additional unit, typically $10,000 to $15,000.
- Properties near the Galloping Goose Trail and the E&N Rail Trail benefit from good cycling and pedestrian connectivity. View Royal has a designated Transit-Oriented Area under Bill 47, and properties near frequent transit bus stops may also qualify for the six-unit SSMUH allowance.
- Thetis Lake Regional Park and its surrounding environmental buffer may impose development permit area restrictions on nearby lots.
- View Royal's design guidelines are moderate, requiring general architectural compatibility but without the prescriptive material and style requirements found in Oak Bay.
District of Central Saanich
Central Saanich occupies the middle of the Saanich Peninsula and presents a distinct SSMUH context due to its mix of urban residential areas (Brentwood Bay, Saanichton) and extensive Agricultural Land Reserve (ALR) holdings. The district adopted its SSMUH bylaw amendments to comply with Bill 44, but the practical application varies significantly depending on whether a lot is within the urban containment boundary or in a rural or ALR-designated area.
On urban residential lots, Central Saanich permits up to four units on lots of 280 square metres or more, and up to three units on lots under 280 square metres, consistent with the provincial framework. Properties within 400 metres of a frequent transit bus stop (service every 15 minutes) on lots of 280 square metres or more may qualify for up to six units under SSMUH, though Central Saanich has limited frequent transit service outside the Brentwood Bay village core. Garden suites are permitted up to 80 square metres in floor area, with a maximum height of 7.5 metres and setbacks of 1.5 metres from side and rear lot lines. The district requires that garden suites maintain architectural compatibility with the surrounding neighbourhood.
Properties within the Agricultural Land Reserve are subject to additional restrictions. Under the Agricultural Land Commission Act, ALR lots may build a principal residence and one secondary suite, but additional units such as garden suites or triplexes are generally not permitted on ALR land unless the ALC grants specific approval. This means that many of Central Saanich's larger rural lots, despite meeting the 280 square metre threshold, cannot take full advantage of SSMUH provisions due to ALR restrictions.
Sewer servicing in Central Saanich is split. The Brentwood Bay and Saanichton areas are generally connected to municipal sewer, but many rural properties rely on septic systems. New dwelling units on unsewered lots require a septic assessment, and the district may require connection to municipal sewer if a main is available within a defined distance. Development Cost Charges range from approximately $12,000 to $18,000 per unit. Building permit processing times average 12 to 16 weeks.
- Central Saanich does not have a designated Transit-Oriented Area under Bill 47. Properties near frequent transit bus stops may still qualify for the six-unit SSMUH allowance if they meet the 400-metre and lot size requirements.
- Lots on the eastern slopes toward the Saanich Inlet may require geotechnical assessments due to steep terrain.
- The district has tree protection bylaws that require permits for removing trees over a specified caliper on development sites.
District of North Saanich (Exempt)
North Saanich is a predominantly rural municipality at the northern tip of the Saanich Peninsula. It does not have designated SSMUH areas because the district falls outside the urban containment boundary established by the Capital Regional District. Bill 44's SSMUH requirements apply only to municipalities within urban containment boundaries, so North Saanich is exempt from the obligation to pre-zone for multi-unit housing on single-family lots.
The practical factors reinforcing this exemption include the prevalence of Agricultural Land Reserve (ALR) land throughout the district, the absence of municipal sewer infrastructure on most properties, and lot sizes that are generally much larger than urban residential lots. Properties in North Saanich rely on private septic systems, which limits the number of dwelling units any given lot can support. On ALR land, the Agricultural Land Commission restricts additional dwellings to one secondary suite within the principal residence.
If you own property in North Saanich and are interested in adding a secondary suite or exploring other housing options, contact the North Saanich planning department directly. Some housing options may still be available under existing bylaws, but the SSMUH framework described in this guide does not apply.
Town of Sidney
Sidney is a compact, fully urban municipality on the Saanich Peninsula with a well-defined town centre and established residential neighbourhoods. The town adopted its SSMUH bylaw amendments to comply with Bill 44, and its urban character makes most residential lots straightforward candidates for SSMUH development.
Sidney permits up to four units on residential lots of 280 square metres or more, and up to three units on lots under 280 square metres. Most residential lots in Sidney fall in the 500 to 700 square metre range, making them eligible for up to four units under SSMUH. Garden suites are permitted up to 75 square metres in floor area, with a maximum height of 7.5 metres and minimum setbacks of 1.5 metres from side and rear lot lines.
Sidney is fully serviced by municipal sewer and water, which eliminates the septic constraints that affect neighbouring North Saanich. All new dwelling units must connect to the municipal sewer system. The town's relatively flat terrain means geotechnical assessments are rarely required, which reduces pre-construction costs compared to hillier municipalities.
Sidney does not have a designated Transit-Oriented Area under Bill 47, but properties within 400 metres of a frequent transit bus stop (service every 15 minutes) on lots of 280 square metres or more may still qualify for up to six units under SSMUH. The town centre has reasonably frequent bus service along the Pat Bay Highway corridor. The Victoria International Airport is located immediately adjacent to Sidney, and the BC Ferries Swartz Bay terminal is a short distance north.
- Building permit processing in Sidney averages 10 to 14 weeks for standard SSMUH applications.
- Development Cost Charges typically range from $10,000 to $14,000 per additional unit.
- Sidney's design guidelines require general architectural compatibility with the existing streetscape but are less prescriptive than Oak Bay's requirements.
- Properties near the Sidney waterfront may be within a development permit area for coastal flooding or sea-level rise, which can affect building placement and foundation design.
- The town has a small number of heritage properties in the downtown core that may face additional design review for visible alterations.
District of Metchosin (Exempt)
Metchosin is a rural municipality on the southern tip of the West Shore, known for its large lots, agricultural heritage, and commitment to preserving rural character. Like North Saanich, Metchosin does not have designated SSMUH areas because it falls outside the urban containment boundary. Bill 44's mandatory pre-zoning for multi-unit housing does not apply to Metchosin.
The district has no municipal sewer system, all properties rely on private septic systems, which is the single largest practical constraint on adding dwelling units. A significant portion of Metchosin is within the Agricultural Land Reserve, further limiting development options. On ALR land, the Agricultural Land Commission restricts additional dwellings to one secondary suite within the principal residence.
Homeowners in Metchosin who are interested in adding a secondary suite or exploring other housing options should contact the Metchosin planning department. Some options may be available under existing bylaws, but the SSMUH density provisions described in this guide do not apply to properties in Metchosin.
Garden Suites & Secondary Suites
Garden suites and secondary suites are the most common entry points for homeowners exploring SSMUH. Understanding the distinction is important:
Secondary suites
A secondary suite is a self-contained dwelling unit located within the principal building (usually a house). Common configurations include basement suites, above-garage suites, and suites created by converting part of an upper floor. Secondary suites must meet BC Building Code requirements for separate entrance, fire separation, egress windows, smoke alarms, and ceiling heights. Converting an existing space to a legal secondary suite typically costs $80,000 to $150,000 depending on the scope of work.
Garden suites
A garden suite is a detached, self-contained dwelling unit on the same lot as the principal building. Garden suites are sometimes called laneway houses, carriage houses, backyard cottages, or accessory dwelling units (ADUs). Under SSMUH, garden suites are typically limited to 70 to 90 square metres of floor area, with maximum heights of 7.5 to 9 metres (depending on the municipality) and minimum setbacks of 1.5 to 3 metres from property lines.
Building a new garden suite in Greater Victoria typically costs $200,000 to $400,000 for a one- or two-bedroom unit, including design, permits, servicing, and construction. Pre-fabricated or modular garden suites can sometimes reduce costs, but site preparation, foundation, and servicing costs remain significant.
Water and sewer considerations
One of the most important practical considerations for secondary and garden suites is water and sewer servicing. Most Greater Victoria municipalities require new suites to be connected to municipal sewer. If your property currently relies on a septic system, you may need to connect to the municipal sewer network before building an additional unit, which can add $20,000 to $80,000 or more depending on the distance to the nearest connection point.
Parking Under SSMUH
Parking requirements have historically been one of the biggest barriers to building additional housing units on residential lots. Under SSMUH, the province has significantly reduced what municipalities can require:
- Municipalities generally cannot require more than one off-street parking space per dwelling unit for SSMUH projects.
- For properties within 400 metres of a frequent transit route (a bus route with service at least every 15 minutes during peak hours), parking requirements may be reduced to 0.5 spaces per unit or eliminated entirely.
- Tandem parking (one car behind another in a single driveway) is generally acceptable to meet parking requirements.
- Municipalities cannot require covered or garage parking for SSMUH units.
Reduced parking requirements are one of the most significant practical benefits of SSMUH. On a typical 600-square-metre lot, traditional parking requirements for a fourplex could consume enough space to make the project physically impossible. Under SSMUH, the same lot can accommodate four units with a combination of driveway and on-street parking.
Development Costs & Timelines
Understanding the full cost of an SSMUH project is critical for making informed decisions. Here is a breakdown of the major cost categories:
Soft costs (design and permits)
Architectural and engineering design fees typically run $15,000 to $50,000 depending on the complexity of the project. Building permit fees vary by municipality but generally range from $5,000 to $15,000 per unit. Development Cost Charges (DCCs) are municipal fees that fund infrastructure upgrades and typically range from $10,000 to $40,000 per new unit. Some municipalities offer DCC waivers or reductions for affordable housing or rental housing projects. If you plan to rent out units, understanding BC tenancy rules for secondary suite landlords is essential for budgeting and compliance.
Hard costs (construction)
Construction costs in Greater Victoria generally range from $300 to $500 per square foot for new residential construction, depending on quality of finishes, site conditions, and market conditions. A 900-square-foot garden suite might cost $270,000 to $450,000 to build. A fourplex of 4,000 total square feet might cost $1.2 million to $2.0 million.
Servicing costs
Connecting additional units to water, sewer, and storm drainage infrastructure can cost $30,000 to $100,000 or more, depending on existing connections and municipal requirements. Electrical service upgrades are also common, particularly for properties adding multiple units, and can cost $5,000 to $20,000.
Timeline
A realistic timeline for an SSMUH project from initial planning to occupancy is 12 to 24 months. This includes 2 to 4 months for design and engineering, 2 to 4 months for building permit review, and 6 to 14 months for construction, depending on project scope. Delays are common, particularly during the permit review stage, so building a buffer into your timeline is advisable.
When to Hire Professionals
While SSMUH simplifies the regulatory pathway, the design and construction of multi-unit housing is not a do-it-yourself project. You will need professionals at several stages:
- Architect or building designer to produce construction drawings that meet the BC Building Code and municipal design requirements.
- Structural engineer to ensure the building can withstand seismic loads (critical in Greater Victoria, which is in a high seismic zone).
- Geotechnical engineer for lots with slopes, rock, high water tables, or other challenging soil conditions.
- BC land surveyor to confirm lot boundaries, setbacks, and any easements or rights-of-way before you start design.
- Civil engineer for stormwater management, sewer connections, and servicing design.
- General contractor with experience in multi-unit residential construction.
Engaging the right professionals early saves time and money. A pre-application consultation with your municipality is also strongly recommended before you invest in detailed design work. Many municipalities offer this service at no charge, and it can identify potential issues (like utility easements or tree protection requirements) before they become expensive problems.
For a detailed breakdown of the development consultants you may need and what each one does, see the Development Consultants Guide for BC.

Bill 25, passed in November 2025, made two key changes. First, it redefined ‘restricted zone’ to close a loophole that some municipalities used to avoid the full 4–6 unit density requirement. Second, it set a new compliance deadline of June 30, 2026 for all municipalities to update their zoning bylaws. This applies to all Greater Victoria municipalities including Victoria, Saanich, Langford, Oak Bay, and Colwood.
What is SSMUH?
SSMUH stands for Small Scale Multi-Unit Housing. It is a provincial framework introduced under BC Bill 44 that requires municipalities to allow multiple housing units on lots that were previously zoned exclusively for single-family homes. The goal is to increase housing supply by enabling gentle density such as duplexes, triplexes, fourplexes, and secondary or garden suites without requiring a rezoning application.
How many units can I build on my lot under SSMUH?
The number of units depends on your lot size and location. On lots under 280 square metres, you can build up to three units (for example, a house with a secondary suite and a garden suite). On lots of 280 square metres or more, you can build up to four units. If your lot is within 400 metres of a frequent transit stop and is 280 square metres or larger, you may be permitted up to six units.
Can I build a garden suite under SSMUH?
Yes. SSMUH provisions allow a detached garden suite (sometimes called a laneway house or backyard cottage) on most single-family zoned lots. The garden suite counts as one of your permitted units. Specific setback, height, and lot coverage requirements vary by municipality, but the provincial framework ensures that municipalities cannot ban garden suites outright on qualifying lots.
What are the minimum lot size requirements for SSMUH?
There is no single minimum lot size for SSMUH because the permitted number of units scales with lot area. Lots under 280 square metres qualify for up to three units. Lots of 280 square metres or more qualify for up to four units. Lots near frequent transit stops may qualify for up to six units. All residential lots are entitled to at least a secondary suite in addition to the primary dwelling.
Do I still need a parking space for each unit?
SSMUH legislation limits what municipalities can require for parking. Generally, municipalities cannot require more than one off-street parking space per unit, and in many cases the requirement is reduced to 0.5 spaces per unit or even zero for lots within 400 metres of a frequent transit stop. Check with your local municipality for the specific parking standards that apply to your lot.
How much does it cost to build SSMUH housing in Greater Victoria?
Costs vary significantly depending on the project type. A secondary suite conversion typically costs $80,000 to $150,000. A new garden suite runs $200,000 to $400,000. A ground-up duplex or fourplex on a vacant lot can range from $500,000 to over $1.5 million depending on finishes, servicing requirements, and site conditions. Development Cost Charges (DCCs) and building permit fees add $15,000 to $50,000 or more per unit depending on the municipality.
How long does SSMUH development take from start to finish?
A typical SSMUH project takes 12 to 24 months from initial planning to occupancy. The building permit process in most Greater Victoria municipalities takes 8 to 16 weeks for straightforward applications. Construction timelines range from 4 to 6 months for a simple garden suite to 10 to 14 months for a fourplex. Factor in additional time for design, engineering, and any required variances.
Which Greater Victoria municipalities have adopted SSMUH bylaws?
SSMUH under Bill 44 applies to municipalities within the Capital Regional District that fall inside the urban containment boundary. Victoria, Saanich, Langford, Colwood, Esquimalt, Oak Bay, View Royal, Central Saanich, and Sidney have all updated their zoning bylaws to comply. Rural municipalities outside the urban containment boundary, including North Saanich, Metchosin, Highlands, and parts of Sooke, are exempt from SSMUH requirements. Implementation timelines and specific rules vary by municipality, so it is important to check with the local planning department.
Do I need to rezone my property to build SSMUH housing?
No. One of the key benefits of SSMUH is that qualifying projects do not require a rezoning application. If your lot meets the size and zoning criteria, you can apply directly for a building permit. This eliminates the public hearing process and significantly shortens approval timelines compared to traditional rezoning, which could take a year or more.
Does SSMUH apply to strata-titled properties?
SSMUH applies to the underlying lot, not the strata title. If you own a freehold single-family lot in a qualifying zone, SSMUH applies. If the lot is already part of a bare land strata or a strata development, you cannot build a new strata dwelling on an existing strata lot. Any additional units built under SSMUH on a strata lot would remain as part of the single strata lot, there would not be separately titled strata units. You may also need strata council approval and amendments to the strata plan before you can build additional units. Fee-simple lots are the most straightforward candidates for SSMUH development.
Can I subdivide my lot under SSMUH?
SSMUH itself does not automatically grant subdivision rights. However, Bill M-216 (the Professional Reliance Act) and related provincial legislation may simplify the subdivision approval process for lots that meet size thresholds. If your lot is large enough, you may be able to both subdivide and build multiple units on each resulting lot. Consult a BC land surveyor and your municipal planning department for specifics.
Will building SSMUH housing increase my property value?
In most cases, yes. Adding legal units to a property increases its rental income potential and its value as an investment property. Properties with development potential under SSMUH are already commanding premiums in Greater Victoria, particularly in desirable neighbourhoods close to transit, schools, and amenities. The actual value increase depends on the quality of construction, location, and market conditions.
What is the difference between SSMUH and a Transit-Oriented Area (TOA)?
SSMUH and TOA are separate programs. SSMUH under Bill 44 provides baseline density on residential lots, allowing up to three, four, or six units depending on lot size and proximity to frequent transit bus service (every 15 minutes). The six-unit SSMUH allowance applies on lots of 280 square metres or more within 400 metres of a frequent transit bus stop. Transit-Oriented Areas (TOAs) under Bill 47 are a completely different framework that applies within 400 metres of designated transit exchanges and allows mid-rise buildings of up to 10 storeys. SSMUH applies broadly to most residential lots; TOAs apply only to properties near specific transit exchange hubs such as UVic, Uptown, and Langford exchange.
Can I build SSMUH housing if my property is in the Agricultural Land Reserve?
Properties within the Agricultural Land Reserve (ALR) face significant restrictions under the Agricultural Land Commission. Generally, the ALC allows one secondary suite within the principal residence on ALR land but does not permit garden suites, duplexes, or other multi-unit configurations. If your property is in the ALR, contact the Agricultural Land Commission to understand what housing options are available before investing in design work.
Does SSMUH apply in North Saanich or Metchosin?
No. North Saanich and Metchosin are rural municipalities that fall outside the Capital Regional District urban containment boundary. Bill 44 SSMUH requirements apply only to municipalities within urban containment boundaries. Some housing options such as secondary suites may still be available under existing local bylaws, but the SSMUH framework for multi-unit density does not apply in these communities.
What happens if my lot is near a transit exchange?
Properties within 400 metres of designated transit exchanges in Greater Victoria may qualify for higher density under Bill 47 (Transit-Oriented Areas) in addition to baseline SSMUH entitlements. TOA density allows up to 10 storeys within 200 metres of an exchange and up to 6 storeys between 200 and 400 metres. Municipalities cannot impose minimum parking requirements in TOA zones (except accessible parking). If your lot is near the UVic, Uptown, Royal Oak, Langford, Colwood, View Royal, or Legislature exchange, check whether it falls within a TOA boundary.
Can I rent out SSMUH units or do I have to live on the property?
Under SSMUH, there is generally no requirement that the property owner live on site. You can rent out all units, including the principal dwelling, secondary suite, and garden suite. However, some municipalities have owner-occupancy requirements for certain unit types under their existing bylaws. Check with your local planning department. Short-term vacation rentals (such as Airbnb) are subject to separate municipal regulations and may be restricted.
What is the maximum height for a garden suite in Greater Victoria?
Garden suite height limits vary by municipality but generally range from 7.5 to 9 metres (roughly two storeys). Victoria allows garden suites up to approximately 7.6 metres. Saanich sets a maximum of 7.5 metres. Langford and most other CRD municipalities fall within the same range. Height is measured differently by each municipality (some measure to ridge, others to midpoint of roof), so confirm the specific measurement method with your local building department.
