Suite & ADU Rules in Coldstream, BC

Local rule · reviewed 8 October 2026

What the municipal rules say

Coldstream Zoning Bylaw 1838 contains zone-specific accessory dwelling and secondary-suite rules.

What applies locally

The rural large-lot R2 schedule contains a secondary-suite restriction on lots below one hectare unless a qualified wastewater professional supplies specified septic-capacity evidence.

Important limits and exceptions

An amnesty process for existing suites is not equivalent to approval for new construction. Confirm zone, sewage system, lot area, parking, permit requirements and any municipal exceptions.

Before work begins: confirm the lot’s actual zoning, mapped overlays, legal parcel characteristics, servicing and applicable building permit conditions with the municipality.

Indexing: City guide: enacted rules summarized; parcel permit not verified. Municipal guidance is a starting point, not a property approval. This page is not municipal permission for a specific address.

This does not change the provincial unit-count math. It only tailors the next-step checklist in your result.

Does local zoning allow residential use on this property?

If you do not know the zoning, choose Not sure.

Is this property inside the municipality’s urban boundary?

What does this mean?

If you have never checked this on a municipal map or plan, choose Not sure.

Is this a regular low-density residential zone?

Why are we asking?

Think houses, duplexes or small multiplexes. If you only know the zone code, choose Not sure.

Does this property have both city water and city sewer?

Does zoning require newly created lots to be about 1 acre or larger?

This is about subdivision rules, not the size of your current lot. Choose Not sure unless you know.

Is this property inside an official Transit-Oriented Area (TOA)?

A TOA is a special mapped area around major transit. If you have never checked the map, choose Not sure.

Is this property officially heritage protected?

Has the municipality specifically confirmed a hazard exemption for this property?

Choose Yes only if the municipality has specifically confirmed it. Otherwise choose Not sure.

Has an official map confirmed this property is within 400 m of a qualifying frequent bus stop?

If you have not checked an official map, choose Not sure.
