Short answer

Burlington Residential Zoning Bylaw 09-2026 came into force March 2, 2026.

What local rules actually say

The city now has two operative zoning bylaws: new Residential Bylaw 09-2026 and older Bylaw 2020 for other lands. The new LN1–LN8 residential zones are not interchangeable with the old R1–R5 schedules.

Important exceptions and the next step

Before concluding that an ARU, detached backyard unit or multiplex is possible, find which bylaw and mapped zone applies and obtain Burlington’s zoning clearance certificate before the building permit.

How to verify an individual property

Look up the legal property address and zone on the official Burlington zoning map.
Confirm the proposed dwelling type: internal suite, addition, detached garden home or multiplex; these can follow different rules.
Verify zone exceptions, lot size, servicing, hazard/heritage limits, any registered restrictions and the current amending bylaws.
Ask the local planning/building office for the required written zoning confirmation and building permits before commissioning construction.

Municipal evidence check · October 12, 2026

Confirmed for this claim: Burlington confirms two zoning bylaws currently apply: new Residential Zoning By-law 09-2026, effective March 2, 2026 for affected lands, and By-law 2020 for other areas. A single municipality-wide ARU rule would be incomplete.

Still to verify: Check which bylaw governs the property, the zoning map, current amendments, ARU design and zoning clearance.

This is a targeted official-source review, not complete certification of every adopted amendment or approval for your property.
