Subdividing a Burnaby Lot Before You Build: Width, Servicing, and the Timeline

A 66-foot lot in Government Road or Buckingham Heights is wide enough to raise a question that did not exist a few years ago. Split it into two lots and build two custom homes, one now and one later? Or keep it whole and build a multiplex under Burnaby's R1 rules? The right answer depends on what the owner wants to hold at the end, and on a year of paperwork that most people have never seen.

What the 2026 zoning bylaw asks of a new lot

Burnaby replaced its 1965 zoning bylaw this year. The Burnaby Zoning Bylaw 2026, Bylaw No. 14815, was adopted on June 9, 2026 and came into effect on July 1, 2026, according to the City's zoning bylaw rewrite page. Detached-house lots across Burnaby sit in the R1 Small-Scale Multi-Unit Housing District, and the subdivision rules for that district are in the R1 district regulations linked from the bylaw page.

Section 1.1.4 of the R1 regulations sets the floor. A new small-scale multi-unit lot needs a minimum lot width of 10 metres, and that figure is the same for an interior lot, a corner lot with a flanking street and a corner lot with a flanking lane. The minimum lot area is 281 square metres. Rowhouse lots are a separate category: 5 metres wide for an interior rowhouse lot, 6.2 metres for an end unit, 8 metres on a corner with a flanking street, with a maximum area of 280 square metres.

A 66-foot lot is 20.1 metres, so two 10-metre lots fit if the depth gives each one 281 square metres. A 50-foot lot is 15.2 metres and cannot become two conforming lots. Depth matters as much as width: a shallow 66-foot lot on a Metrotown block may fall under the area minimum once you halve it.

Irregular shapes get one concession. On a pie-shaped or otherwise asymmetrical lot, the frontage can be narrower than the minimum as long as the average width over a 30-metre depth, measured from the centre of the frontage, meets the minimum. Panhandle lots, where a narrow strip leads to a rear parcel, are not permitted except under the heritage provisions or where the Approving Officer finds the site is constrained.

The same document sets what each new lot can then carry. For 1 to 2 units the front building is limited to 2.5 storeys; for 3 to 4 units it is 3 storeys, with a height cap of 10 metres for a sloping roof and 9.5 metres for a flat roof. Lot coverage for 1 to 2 units is 30 percent on lots over 567 square metres and 40 percent on lots under that. Those two numbers together decide how much house fits on each half, and they are the reason we get the FSR and lot coverage worked out for both new lots before anyone draws a floor plan.

The subdivision application and the Approving Officer

Subdivision in Burnaby is a legal process that changes property boundaries, and it is approved by a municipal Approving Officer, according to the City's subdivision page. The City's Subdivision Approval Guide says Council has appointed the Director Planning and Building to that role, and it adds a line owners should read twice: a subdivision application is not eligible for variances through the Board of Variance. If the lot is 30 centimetres short of the minimum width, there is no appeal route to make up the difference.

The process starts before the application. The City offers a subdivision inquiry for owners who want to know whether the Approving Officer could support a proposal. It needs a formal letter describing the proposed lots and units, a draft subdivision plan prepared by a surveyor, an agent authorization form signed by the owners, and on a corner lot where the orientation changes, a Building Scheme. The City gives a formal response within 8 weeks of a complete submission once the fee is paid. We always do the inquiry. Eight weeks and a surveyor's draft is a small price against a year of work on a plan the City was never going to sign.

The guide lays out the formal application in stages. The application goes in with a topographical survey by a BC Land Surveyor, showing the size, species and driplines of every tree over 8 inches in diameter, and a plot plan if an existing building is being kept. Planning circulates it to Engineering, Parks, Transportation, BC Hydro and Telus. Tentative approval, if it comes, arrives 4 to 5 months after the formal application by the guide's own estimate, and is valid for one year. It comes with a letter of conditions.

Those conditions are the real work. The guide lists examples: a legal survey plan, engineering design drawings for required services prepared by a professional engineer, a letter of credit covering the engineering works, a servicing agreement with the City, restrictive covenants, easements and statutory rights-of-way, and payment of development cost charges. Once every condition is satisfied, the survey plan goes to the Approving Officer for final approval and is deposited at the Land Title Office. The City's page puts the whole process at an average of 6 to 12 months.

A subdivision inquiry costs eight weeks and a surveyor's sketch. Skipping it has cost owners a year. There is no Board of Variance for a lot that is thirty centimetres too narrow.

Servicing: the new lot has to connect to everything

The half of the lot that never had a house on it has no water service, no sewer connection and no storm connection. Supplying those is a condition of the subdivision, and the cost sits with the owner.

The Burnaby Subdivision Control and Development Servicing Bylaw lists what counts as works and services: highways and lanes, boulevards including street trees, sidewalks, curbs and gutters and street lighting; water distribution systems connected to the City's system; sewage collection systems connected to the City's system; drainage collection systems including storm sewers and catch basins; and underground wiring and third-party utilities. Section 6A says the owner of land under a subdivision or building permit application shall provide, alter or replace works and services as a condition of approval, and section 7A puts the responsibility and cost on that owner. Section 7B lets the City's General Manager Engineering take cash instead, where it makes engineering or cost sense to build the works later or together with neighbouring parcels.

What this means on a Burnaby street varies by block. On a Parkcrest street with a modern sewer main and a sidewalk already in place, the works may be two new service connections and a driveway crossing. On an older Capitol Hill street with a ditch instead of a curb, the conditions can include curb, gutter, sidewalk and street lighting across the whole frontage. The civil engineer's design package, which the guide says you obtain from the City's Engineering Department, is where that scope becomes visible. Get it early. It changes the answer to the two-lots-or-multiplex question more than any other single item.

Trees count from the day you apply

The Burnaby Tree Bylaw defines a development application to include an application for subdivision, and on a property under a development application the City protects any tree 20 cm or greater in diameter. The subdivision survey already has to show every tree over 8 inches with its dripline, so the trees are in the file from the first submission.

A big cedar in the middle of a 66-foot lot is the classic problem. Two houses on two new lots need two building envelopes, and the tree's dripline may sit across the new property line and inside both. Retaining it can shrink both houses. Removing it triggers replacement planting, and the tree removal and replacement page sets the count by the size of the tree removed, with a cash-in-lieu contribution to the City's tree reserve fund where the lot cannot hold the replacements. We have the arborist's report done before the subdivision inquiry, because a tree that cannot come out can decide the whole question.

Two lots or one lot with a multiplex

Under the provincial small-scale multi-unit housing legislation, the Province requires municipalities to allow a minimum of 3 units on lots of 280 square metres or smaller, 4 units on lots over 280 square metres, and 6 units near frequent bus service. Burnaby's R1 regulations carry this through: 3 to 4 units on a lot with a minimum area of 281 square metres, and 5 to 6 units in a Frequent Transit Network Area, with lot coverage of 40 percent for 3 to 4 units and 45 percent for 5 to 6.

So the wide lot in Government Road has two futures. Split it, and the owner holds two titles, each with a house that can be sold, mortgaged or left to a child on its own. The price is the subdivision year, the servicing works for the new lot, and two separate building permits. Keep it, and the owner can build up to 4 units, or a main house with a laneway or coach house at the rear, on one title with one permit process and one set of service connections. The units share a lot and, if they are ever sold separately, need a strata plan rather than a subdivision.

We push owners to answer one question before running numbers: who lives here in fifteen years? A family placing a second home for a daughter often wants the separate title, because a title is a clean thing to hand over. An owner who wants rental income and plans to hold the whole property usually does better with the multiplex, because the approval is shorter and the servicing is one set of connections instead of two.

The comparison also depends on the block. A lot that sits inside Burnaby's Frequent Transit Network Area can carry 6 units, which changes the math against two lots with two houses. The lot evaluation checklist we use on teardown purchases covers how to confirm that before buying.

What subdivision does to the custom home schedule

The subdivision runs first and the building permit runs after it, in series. The new lot has to exist at the Land Title Office before a building permit can be applied for on it, and the City's own average of 6 to 12 months sits in front of the permit timeline that any Burnaby custom home already carries.

Design is the part that can run alongside the subdivision. During the tentative approval period we take the house through schematic design and into permit drawings, using the draft lot lines from the surveyor. The energy modelling, the structural design and the civil design for the driveway and site grading can all progress. When the plan registers, the permit application goes in the same month. Owners who wait for registration before starting design lose most of a year for no reason.

The other overlap is the servicing works themselves. Where the conditions include curb, sidewalk and service connections across the frontage, that construction can be sequenced with the excavation for the house on the first lot, so the street is torn up once instead of twice. The civil engineer coordinates this with the City's Engineering Department, and the letter of credit stays in place until the works are accepted.

On the Government Road lot, the family chose two lots. The first house is in design while the subdivision moves through its conditions, and the second lot will sit serviced and fenced until the daughter is ready. A title she can hold in her own name was the point. On a Brentwood lot the same year, a different owner chose the fourplex, because rental income in 2027 mattered more than a second title in 2032.

Frequently asked questions

What is the minimum lot width to subdivide in Burnaby?

Under the R1 Small-Scale Multi-Unit Housing District regulations in the Burnaby Zoning Bylaw 2026, a new small-scale multi-unit lot needs a minimum width of 10 metres, whether it is an interior lot or a corner lot, and a minimum area of 281 square metres. Rowhouse lots are a separate category with narrower minimums and a maximum area of 280 square metres. Confirm the current figures with the City before you engage a surveyor.

How long does a subdivision take in Burnaby?

The City of Burnaby says subdivision applications take 6 to 12 months on average, depending on complexity and how quickly the applicant responds to conditions. A subdivision inquiry, which asks the City whether the Approving Officer could support a proposal, gets a formal response within 8 weeks of a complete submission. The building permit for the new house runs after the subdivision is registered.

Who is the Approving Officer for a subdivision in Burnaby?

Burnaby Council has appointed the Director Planning and Building as the Approving Officer, according to the City's subdivision approval guide. Every subdivision must receive the Approving Officer's approval, and a subdivision plan can be refused if the Approving Officer considers it against the public interest. A subdivision application is not eligible for a variance through the Board of Variance.

Can I subdivide a corner lot in Burnaby?

The R1 regulations set the same 10 metre minimum width for a small-scale multi-unit lot whether it is an interior lot, a corner lot with a flanking street, or a corner lot with a flanking lane. On a corner lot where the orientation of the new lots changes, the City asks for a Building Scheme as part of a subdivision inquiry. Pie-shaped and irregular lots can average their width over a 30 metre depth, but panhandle lots are not permitted except in limited cases.

Who pays for the water and sewer connections to a new lot in Burnaby?

The owner does. Burnaby's Subdivision Control and Development Servicing Bylaw requires the owner of land under a subdivision application to provide, alter or replace works and services as a condition of approval, and it lists water distribution, sewage collection, drainage, roads, sidewalks and underground wiring among those works. The City's General Manager Engineering can instead require a cash payment covering the cost where it makes sense to build the works later.

Does subdividing a lot in Burnaby trigger the tree bylaw?

Yes. The Burnaby Tree Bylaw defines a development application to include a subdivision application, and on a property under a development application any tree 20 centimetres or greater in diameter is protected. The City's subdivision guide also asks for a topographical survey showing the size, species and driplines of trees over 8 inches in diameter, so the trees are on the table from the first submission.

Is it better to subdivide a large Burnaby lot or build a multiplex on it?

It depends on what the owner wants to own at the end. Subdividing produces two separate titles, each able to carry its own house and its own future sale, at the cost of a 6 to 12 month approval and the servicing works for the new lot. Keeping one lot and building under the R1 rules can produce up to 4 units on a lot over 280 square metres, and up to 6 in a Frequent Transit Network Area, without a subdivision. We run both scenarios before an owner commits to either.

How does a subdivision change the timeline for a custom home in Burnaby?

It adds the subdivision approval in front of the building permit, and the two do not run in parallel. The City's guide estimates tentative approval 4 to 5 months after a formal application, followed by conditions such as engineering design drawings and a servicing agreement, then final approval and registration at the Land Title Office. Design work for the house can proceed during that period, but the permit application waits for the new lot to exist.
