Prince George, BC suite & ADU rules

Permission first. Construction second.

Prince George publishes an official guide specifically for constructing or legalizing secondary suites. The guide routes owners through zoning eligibility, parking and permit requirements rather than treating every house as automatically eligible.

Can’t find your address?

Use the manual property check below.

Start with the municipality and parcel area. The manual check stays open here, but the questions are split into 4 short steps so you do not have to scroll through everything at once.

Manual property check

Check the lot using what you know.

Four short steps. Answer what you know and choose “Not sure” for anything you have not checked.

Step 1 of 4Property basics
Step 1: Property basics

Use the parcel area from your property record, assessment or municipal mapping tool.

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

Step 2: Basic zoning checks

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

What does this mean?

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

Why are we asking?

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

Step 3: Possible exceptions

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

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

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

Step 4: Frequent bus check

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

Private by default: the calculation runs in your browser. No name, phone number or email is required.

Prince George: secondary suite and detached ADU rules

Prince George’s Zoning Bylaw No. 7850 has been repeatedly amended for SSMUH, with a current consolidation posted in 2026. Site coverage and accessory-building limits vary by zone, so the page now cites zone examples without pretending they are city-wide.

Secondary suite

  • Secondary suites are listed as a secondary use in multiple residential zones. Current SSMUH amendments allow higher total unit counts in qualifying low-density zones.
  • The parking standard in the cited 2026 City options guide is 1 space per secondary suite. Council described proposed parking reductions on August 17, 2026, including a potential zero-space requirement for secondary suites and secondary dwellings; that meeting summary does not establish enactment. Use the latest signed amending bylaw and adopted parking table before relying on any proposed reduction.

Garden / carriage / detached ADU

  • “Secondary dwelling” is the City’s detached/additional-dwelling term in the Zoning Bylaw and is a listed secondary use in multiple residential zones.
  • The cited 2026 City options guide lists 1 space per secondary dwelling; verify the adopted zoning parking table, including any later amendment adopted after the August 2026 proposals.

Parking, size & site limits

  • Size / coverage are zone-specific: for example, current RS2 has 40% maximum site coverage and a 90 m² maximum combined gross floor area for accessory buildings/structures; other zones differ.
  • Height: current RS2 permits secondary dwellings up to 8 m, while other zones can use different heights.
  • Do not use the former 40%-of-principal-dwelling suite-size rule as a current city-wide standard; SSMUH amendments deleted/reworked legacy provisions.

Prince George suite / ADU FAQ

Do I need a permit?

Yes. A new secondary suite or detached dwelling needs the applicable Prince George approvals and building permit before construction/occupancy. Existing work may require a legalization or existing-building review rather than simply a new-build permit.

Can I rent the unit?

A permitted suite or secondary dwelling can be used as a residence/rental subject to City and provincial rules. Permit and occupancy status remain separate from zoning permission.

Is an old or “grandfathered” suite automatically legal?

No. Age or long-standing occupancy does not by itself prove municipal approval. Check Prince George permit/property records and, where relevant, whether a lawful non-conforming status actually exists before describing a suite as “grandfathered.”

Can I have both an internal suite and a detached ADU?

Potentially, where the current zone and maximum residential density allow the combination. Check the exact zone schedule and the City’s current SSMUH provisions.

Optional project planning

After the rule check: budget and contractor scope

Use these tools only after confirming the municipal path. Cost planning and contractor matching do not establish zoning, code compliance or permit approval.

How this guide was verified

Guide verification: Targeted municipal source review documented. Selected rule or adoption claims were checked against named official material and recorded in the site research notes. This is not a complete current bylaw, zoning-map or amendment certification.

Property confidence: Not assessed. City-wide guidance does not confirm permission for a particular parcel. Check official zoning, overlays and permits. How verification works →
