Home Addition Services in Burnaby
Burnaby's large stock of 1960s-1980s split-levels and ranchers on generous suburban lots creates excellent opportunities for home additions, with more permissive zoning and lower land costs than Vancouver proper making expansions more economically viable.

Home Addition Considerations for Burnaby
Burnaby operates its own building department, separate from the City of Vancouver, with distinct permit processes, fee structures, and zoning bylaws that homeowners must follow for addition projects.
Many Burnaby homes built in the 1960s through 1980s are single-storey ranchers on generous lots, making them excellent candidates for second-storey additions that can effectively double the living space without expanding the building footprint.
Burnaby's varied zoning districts (R1 through R12 and beyond) each have different setback, height, and floor area ratio requirements, so confirming your specific zoning designation early in the planning process is essential.
Seismic upgrading to current BC Building Code standards is required for additions in Burnaby, as the municipality sits within the same high seismic zone as the rest of Metro Vancouver.
Larger lots in areas like Burnaby Heights, Capitol Hill, and the Deer Lake neighbourhood may provide more flexibility for ground-floor extensions, but steep topography in some areas can increase foundation and site preparation costs significantly.
Burnaby's tree protection bylaw requires permits before removing any tree with a trunk diameter of 20 centimetres or more, which can affect addition placement and construction access on heavily treed lots.
Homes in Burnaby's designated Heritage Conservation Areas may face additional design review requirements to ensure additions are compatible with the established neighbourhood character.
Permits & Regulations
Home addition permits in Burnaby are processed through the City of Burnaby's Planning and Building Department, located at Burnaby City Hall. For most residential additions, you will need a building permit, and depending on the scope, a preliminary plan approval (PPA) may also be required. Burnaby's building permit fees for residential additions are calculated based on construction value, typically ranging from $1,200 to $4,500 for standard projects. A preliminary plan approval application, if required, adds approximately $1,000 to $2,500 in fees. Permit processing times in Burnaby generally range from 6 to 12 weeks for straightforward additions, though second-storey additions and projects requiring variances can take 12 to 20 weeks or longer. If a development variance permit is needed — for example, to exceed maximum height or reduce a required setback — the process includes a public notification period and may require a public hearing, adding 8 to 16 weeks to the timeline. Burnaby offers a pre-application review service that is highly recommended for larger addition projects. All additions must comply with the BC Building Code, including current seismic design requirements for the region's high earthquake risk classification. Burnaby also enforces the BC Energy Step Code, and most residential additions will need to meet Step 3 energy efficiency targets or higher. Registered professionals (architects and structural engineers) are required for the design of second-storey additions and any project involving structural modifications. The city conducts mandatory inspections at each stage of construction, from foundation through to final occupancy.
About Burnaby
Burnaby is one of Metro Vancouver's largest municipalities, with a housing stock that spans from postwar bungalows and 1960s-era ranchers to modern infill homes. The city's generous lot sizes — particularly in neighbourhoods like Burnaby Heights, Capitol Hill, Parkcrest, and the Deer Lake area — make it one of the most popular locations in the region for home additions, especially second-storey additions that can transform a modest rancher into a spacious family home. The relative affordability of older Burnaby homes compared to Vancouver proper, combined with excellent transit access via SkyTrain (Millennium and Expo lines), drives strong demand for renovation and expansion rather than purchasing a larger home. Burnaby's topography varies considerably, from flat areas near Boundary Road to steep hillsides around Capitol Hill and Burnaby Mountain. This terrain directly affects addition costs, as sloped sites may require engineered retaining walls, specialized foundation work, and more complex drainage solutions. The city's mature urban tree canopy is another factor — Burnaby's tree protection bylaw means that large trees near the building envelope may need to be worked around or formally assessed before removal permits can be granted, potentially influencing the placement and design of an addition.
Frequently Asked Questions: Burnaby Home Additions
How much does a second-storey addition cost in Burnaby?
A full second-storey addition in Burnaby typically costs between $300 and $500 per square foot, depending on design complexity, finishing level, and the condition of the existing structure. For a typical 1960s or 1970s rancher adding 800 to 1,200 square feet of upper-floor living space, expect a total project cost of $280,000 to $550,000. This includes structural reinforcement of the existing first floor, new roofing, exterior cladding, and interior finishing. Seismic and foundation upgrading, if required, can add $20,000 to $50,000.
What is the cost of a ground-floor rear addition in Burnaby?
Ground-floor rear additions in Burnaby generally cost between $350 and $550 per square foot for fully finished space. A 200-square-foot kitchen extension might cost $80,000 to $120,000, while a larger 400 to 500-square-foot family room addition could range from $160,000 to $275,000. Projects on sloped lots or those requiring significant foundation work will be at the higher end. Permit fees, design professional fees, and GST are typically additional costs beyond the construction contract.
Do I need an architect for a home addition in Burnaby?
For second-storey additions and any project involving significant structural changes, the City of Burnaby requires plans prepared by a registered professional — either an architect or a structural engineer. For smaller single-storey additions that do not involve structural modifications, a qualified residential designer may be sufficient, though the city may still require engineering for foundations and structural elements. In all cases, having a professional who is familiar with Burnaby's specific zoning bylaws and permit processes can save considerable time and expense.
How does Burnaby's zoning affect what I can add to my home?
Burnaby has numerous residential zoning districts, each with specific rules for maximum lot coverage, floor area ratio (FAR), building height, and required setbacks from property lines. For example, many R5-zoned properties allow a maximum FAR of 0.50 to 0.55, meaning a 6,000-square-foot lot could support approximately 3,000 to 3,300 square feet of total floor area including the existing home and addition. Your zoning designation determines how much you can add, so confirming these limits with Burnaby's planning department before investing in detailed design is essential.
Can I live in my Burnaby home during a second-storey addition?
In most cases, homeowners can remain in their home during the early stages of a second-storey addition, particularly during foundation reinforcement and structural preparation. However, once the existing roof is removed and upper-floor framing begins, the home will be exposed to weather and construction activity that makes occupancy impractical and potentially unsafe. Most families plan for 6 to 10 weeks of alternative accommodation during the most intensive construction phases. Your contractor should provide a detailed phasing plan so you can arrange temporary housing in advance.
