Start with Maple Ridge’s current suite guidance
Maple Ridge’s current secondary-suite guidance allows one suite per lot within the same building as the single detached dwelling, subject to the city’s zoning and other site conditions. A building permit is required; detached garden suites follow a separate city process.

British Columbia: the provincial layer
B.C. legislation and the SSMUH policy framework expand secondary-suite and accessory-dwelling opportunities across the province. The exact lot still needs a municipal zoning, site-standard and permit check.
BC small-scale multi-unit housing ↗Four things to establish before the renovation
What kind of unit?
Do not treat an internal suite and a detached garden unit as the same planning problem; the site rules can be very different. Keep the Maple Ridge property and proposed unit form in view when applying that requirement.
Is the use allowed?
Before drawing walls, confirm that the property qualifies for the unit type under the current provincial and municipal framework.
Can the building comply?
Code compliance is a separate gate: check egress, fire separations, life-safety alarms, ventilation and structural adequacy. Keep the Maple Ridge property and proposed unit form in view when applying that requirement.
Can the site serve it?
A permitted use can still be difficult to build if the lot cannot satisfy servicing, access or site-layout requirements.
From Maple Ridge zoning to final inspection
Before detailed drawings, establish the parcel’s entitlement and the correct municipal category for the unit. Then test the design against code and servicing.
For an older suite, confirm whether it was permitted under a previous rule, legalized later, or never received final approval.
