The local suite route in Richmond
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.

British Columbia: the provincial layer
British Columbia’s SSMUH rules broaden the housing that local governments must allow in many residential zones. Secondary suites and detached ADUs are part of that framework, but municipal siting, permitting and applicable exemptions still matter.

What kind of unit?
The approval route can change depending on whether the new home is internal, attached or detached from the main dwelling.
Is the use allowed?
Separate entitlement from construction. The city may allow another unit in principle while still regulating its size, location or form.
Can the building comply?
The building-code review should cover exits, fire separation, smoke/CO protection, ventilation and any structural changes. Keep the Richmond property and proposed unit form in view when applying that requirement.
Can the site serve it?
Site planning should include service routes and access, not only the new unit’s floor plan.
How to sequence a Richmond suite project
A good sequence is property eligibility, unit type, building design, utilities/trades and inspections. Starting with finishes can hide the expensive constraints.
A real-estate listing can describe a suite without proving it is legal. Ask for the municipal approval history before valuing it as an approved unit.
