Municipal multiplex screen · reviewed August 11, 2026

Coquitlam multiplex rules: screen the parcel before the project.

Council adopted SSMUH zoning changes on June 9 and supporting amendments on June 23, 2025; the City says small-scale housing is allowed in most low-density areas.

What the public record says

Forms include secondary suites, garden cottages, carriage houses, duplexes, triplexes, fourplexes, and multiplexes; use the parcel-level rules rather than a generic maximum.

That is a planning signal, not a project approval. Use the current municipal bylaw and property-specific records before relying on any unit-count scenario.

First parcel check

Check the mapped zone and complete the City’s small-scale housing pre-application checklist before treating a concept as buildable.

Record the source, date, zone, and map result in the feasibility file. If the result is unclear, stop before commissioning design or underwriting land value.

What can change the outcome

Entitlement is not buildability.

The permitted housing form, drainage, trees, parking, engineering needs, and development-permit triggers vary by neighbourhood and site.

A defensible next step

Use a four-part pre-design file.

Municipality, current zone, map, lot dimensions, and relevant overlays.
The adopted zoning text and the exact source date—not a summary from a listing.
Survey, access, servicing, tree, drainage, and site-condition questions.
Scenario economics that preserve downside assumptions and do not turn density into automatic land value.

Commercial boundary

Parcel & Key's municipal screen is educational decision support. It is not legal, planning, surveying, engineering, code, tax, appraisal, construction-cost, financing, or permit advice.
