The rules ledger keeps this form conditional until the address, governing jurisdiction, parcel and current zoning are verified.
Mission, BC suite & ADU rules
Check the property before choosing the building form.
Mission’s current planning framework includes secondary suites and zoning provisions for additional housing forms. The City’s secondary-suite program also requires new suites to proceed through the building-permit process.

What may be possible in Mission?
The cards below are a safe starting point, not a permit decision. The address checker is the deciding first step because the exact zone, parcel and site conditions can change the result.
Detached garden / backyard unit

The site needs more property evidence before it can make a reliable planning call for this form.
What controls the answer
Current municipal source: the page links directly to the local authority used for this guide.
Property evidence: municipality, parcel identity, zoning, lot area and relevant site conditions must agree before a strong result is shown.
Building form: a provincial unit-count starting point does not automatically create a right to a particular duplex, triplex, fourplex, suite or detached unit.
Local context
Mission’s zoning bylaw contains different residential zones and building forms. The exact zone, servicing and site conditions control whether a suite, detached unit or multiplex form is available.
Rules-engine scope: Regional coverage fallback added September 23, 2026. The site does not infer an exact-zone permission where the municipal zoning layer is not connected; exact zoning and site conditions still control.
How to use this page: run the address check, read the evidence shown for the property, then open the official municipal source before spending money on plans or construction.

Mission: what to verify before you build
Mission’s current planning framework includes secondary suites and zoning provisions for additional housing forms. The City’s secondary-suite program also requires new suites to proceed through the building-permit process.
1. Confirm the jurisdiction and zone
- Use the civic address and parcel, not a nearby neighbourhood name, to identify the governing local authority.
- Read the current zoning designation and any comprehensive-development or special-area rules before relying on a housing form.
2. Confirm the housing form
- Internal suites, detached accessory dwellings and multiplex forms are separate planning questions.
- A unit-count framework is not a substitute for setbacks, coverage, height, access, parking, servicing, hazard and development-permit requirements.
3. Confirm permits and site constraints
- Building-code compliance and municipal land-use permission are separate layers; both can apply.
- Registered title constraints, servicing, environmental/hazard areas and other parcel-specific conditions can change what is practical even when a use is generally supported.
Mission property-check FAQ
Does a CONDITIONAL result mean I can build it?
No. It means the audited framework may support that form, but the property still needs its exact zoning and site conditions verified.
Why can the address result say MORE INFORMATION NEEDED?
The site uses that result when a required fact could not be verified strongly enough. It is intentionally safer than inventing a permitted or not-permitted answer.
What should I do before ordering drawings?
Save the official municipal source, confirm the current zone and parcel facts, and verify the permit path for the exact housing form you are considering.
