Richmond’s residential regulations allow one secondary suite within a single-family detached home when the suite is brought into compliance with the BC Building Code and city bylaws. Inspection and approval are part of making the suite legal. Richmond’s Building-22 bulletin is the municipal starting point for secondary-suite floor-area and building requirements; a citywide summary does not replace checking the applicable zoning district.
Select a B.C. property to check the parcel, available zoning and suite-planning data.
The automated checker cannot confirm all zoning amendments, overlays, lot restrictions, servicing or building permits. Free human property-review requests are currently paused.
See the official verification steps →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.
Four short steps. Answer what you know and choose “Not sure” for anything you have not checked.
Richmond replaced many former single-family/coach-house zones with Small-Scale Multi-Unit Housing (RSM) zones in 2024 and has continued parking amendments through 2026. Older coach-house zone sheets should not be treated as city-wide current rules.
Yes. A new secondary suite or detached dwelling needs the applicable Richmond approvals and building permit before construction/occupancy. Existing work may require a legalization or existing-building review rather than simply a new-build permit.
A legal suite or other dwelling can be rented subject to current City and provincial rules. Approval/inspection status should be confirmed before occupancy or advertising.
No. Age or long-standing occupancy does not by itself prove municipal approval. Check Richmond permit/property records and, where relevant, whether a lawful non-conforming status actually exists before describing a suite as “grandfathered.”
Potentially in current RSM configurations; confirm the RSM zone, total unit count and parking/access standards. Older “suite versus coach house” restrictions may have been superseded by the 2024–2026 SSMUH amendments.
Use these tools only after confirming the municipal path. Cost planning and contractor matching do not establish zoning, code compliance or permit approval.
Guide verification: Targeted municipal-source claim check recorded. Selected citywide guidance or adoption facts were checked against an identified official page on October 12, 2026. This is not a complete current-bylaw, amendment-map or parcel certification.
Property confidence: Not assessed. City-wide guidance does not confirm permission for a particular parcel. Check official zoning, overlays and permits. How verification works →
Reviewed September 20, 2026. This is a planning summary, not a permit decision. Confirm the current zoning, registered title constraints, servicing and permit requirements for the specific property before design or construction.
V69.62 targeted primary-source review · October 12, 2026: Richmond says one inspected and approved secondary suite may be allowed within a single-family detached home; separately, council records show RSM/L, RSM/M and RSM/XL are operative zone categories, not a citywide approval. Official municipal record ↗ Still unverified: Confirm Bylaw 8500 current RSM district schedule, amendments, title constraints and actual mapped property zone. No comprehensive current-by-law signoff or parcel approval is claimed.
