Burnaby, BC suite & ADU rules

Permission first. Construction second.

Burnaby’s Secondary Suite Program says a suite must be contained within the primary home. Existing single-family, duplex, multiplex and rowhouse projects still have to meet zoning conditions, the BC Building Code, obtain the required building and trade permits, and pass inspections.

Use the manual property check below.

Start with the municipality and parcel area. The manual check stays open here, but the questions are split into 4 short steps so you do not have to scroll through everything at once.

Manual property check

Check the lot using what you know.

Four short steps. Answer what you know and choose “Not sure” for anything you have not checked.

Step 1 of 4Property basics
Step 1: Property basics

Use the parcel area from your property record, assessment or municipal mapping tool.

This does not change the provincial unit-count math. It only tailors the next-step checklist in your result.

Step 2: Basic zoning checks

If you do not know the zoning, choose Not sure.

What does this mean?

If you have never checked this on a municipal map or plan, choose Not sure.

Why are we asking?

Think houses, duplexes or small multiplexes. If you only know the zone code, choose Not sure.

Step 3: Possible exceptions

This is about subdivision rules, not the size of your current lot. Choose Not sure unless you know.

A TOA is a special mapped area around major transit. If you have never checked the map, choose Not sure.

Choose Yes only if the municipality has specifically confirmed it. Otherwise choose Not sure.

Step 4: Frequent bus check

If you have not checked an official map, choose Not sure.

Burnaby: secondary suite and detached ADU rules

Burnaby consolidated former low-density R zones into the R1 Small-Scale Multi-Unit Housing District. The answer now depends on R1 unit count, transit location and the building form, not the old single-family/laneway rule set.

Secondary suite

  • Secondary suites are allowed within qualifying single-family homes, duplexes, multiplexes and rowhouses in R1 and specified other zones; building and required subtrade permits plus inspections are required.
  • A secondary suite is part of the primary building. Burnaby’s current small-scale housing rules also allow detached/laneway-style principal-building forms, so do not assume an old “laneway home = accessory building” rule still applies.

Garden / carriage / detached ADU

  • R1 permits multiple small-scale housing forms, including detached configurations. Current Burnaby guidance treats laneway-style homes as one of the permitted R1 housing forms rather than applying the former laneway-home framework universally.
  • A detached form may itself contain a secondary suite where the R1 configuration permits it; total dwelling-unit limits still apply.

Parking, size & site limits

  • Parking: Burnaby’s current R1 rules vary with Frequent Transit Network Area status and dwelling configuration. Within the eligible transit area there is no residential parking minimum; outside it the R1 table generally calculates 1 space for the first unit plus 0.5 space per additional unit. Confirm the applicable Part 7 zoning table, mapped transit status and any project-specific exceptions with the City before treating that formula as approved parking.
  • Floor area: current R1 guidance does not set one stand-alone maximum dwelling floor area; buildable area is controlled by setbacks, height, site coverage and other R1 rules.
  • Lot coverage: current R1 summary generally uses 40% for 1–4 units, with a 30% exception for 1–2 units on lots over 567 m²; 5–6 unit forms can reach 45%, and rowhouse forms 55%. Verify the live R1 table for the specific form.

Burnaby suite / ADU FAQ

Do I need a permit?

Yes. A new secondary suite or detached dwelling needs the applicable Burnaby approvals and building permit before construction/occupancy. Existing work may require a legalization or existing-building review rather than simply a new-build permit.

Can I rent the unit?

A permitted suite or other dwelling can be used for lawful residential occupancy/rental subject to applicable City and provincial rules; the building must have the required approvals.

Is an old or “grandfathered” suite automatically legal?

No. Age or long-standing occupancy does not by itself prove municipal approval. Check Burnaby permit/property records and, where relevant, whether a lawful non-conforming status actually exists before describing a suite as “grandfathered.”

Can I have both an internal suite and a detached ADU?

Yes in some R1 configurations, subject to the total permitted unit count and building form. The current R1 rules—not the former laneway-home rules—should be used for a new proposal.

Optional project planning

After the rule check: budget and contractor scope

Use these tools only after confirming the municipal path. Cost planning and contractor matching do not establish zoning, code compliance or permit approval.

Current municipal rule checkpoint

Burnaby’s Secondary Suite Program identifies R1, A1, A2, A3 and RM6 as the applicable existing-home zones for suites within eligible single-family, duplex, multiplex or rowhouse buildings. Building Code compliance, permits and inspections still apply. Laneway-style buildings are regulated separately under the newer R1 housing framework; do not infer a blanket right to detached units from an internal-suite approval.

Source review: October 9, 2026. This is an informational bylaw checkpoint, not a parcel-specific approval. Verify enacted amendments, zone maps, registered title constraints, servicing and permits with the municipality.

How this guide was verified

Guide verification: Targeted official-source check (12 October 2026). The key claim below was compared with a linked primary municipal source; this is not a complete up-to-date bylaw, zoning-map or parcel approval review.

Property confidence: Not assessed. City-wide guidance does not confirm permission for a particular parcel. Check official zoning, overlays and permits. How verification works →
