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.

Abbotsford: secondary suite and detached ADU rules

Abbotsford now uses its current SSMUH zoning and property-specific zone rules; older Urban 3 infill numbers should not be treated as city-wide limits after the 2025 OCP update.

Secondary suite

  • Secondary suites are permitted on most single-detached or duplex properties, but the property zoning still has to permit the proposed dwelling configuration.
  • A suite created or legalized through the City permit process must comply with the applicable building-code and zoning requirements; an existing finished basement is not proof of approval.
  • Current City guidance requires at least 1 on-site parking space for a secondary suite.

Garden / carriage / detached ADU

  • Garden suites and coach houses are recognized SSMUH/accessory-unit forms, but eligibility, siting and building form depend on the property’s current SSMUH or other residential zone.
  • Do not reuse the former Urban 3 “540 m² garden-suite lot” rule as a universal current standard; verify the live zone in WebMap/Zoning Bylaw before design.

Parking, size & site limits

  • Parking: at least 1 space for a secondary suite under current City guidance; other SSMUH configurations use the current parking sections of the Zoning Bylaw.
  • Size / coverage: no single city-wide detached-ADU floor-area cap is safe to quote across all current Abbotsford residential zones; use the current zone schedule.
  • Unit count: current SSMUH rules can permit multiple dwelling units on qualifying lots, but that does not mean multiple “secondary suites” can be created under the secondary-suite building-code definition.

Abbotsford suite / ADU FAQ

Do I need a permit?

Yes. A new secondary suite or detached dwelling needs the applicable Abbotsford 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?

Long-term rental is possible where the unit is legal and the proposed use complies with City bylaws and provincial tenancy rules. Separate licensing or other use rules may apply to non-standard rental uses.

Is an old or “grandfathered” suite automatically legal?

No. Age or long-standing occupancy does not by itself prove municipal approval. Check Abbotsford 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, depending on the current zone and total unit count. Treat “secondary suite,” “garden suite,” and “coach house” as different dwelling forms and confirm the property’s current SSMUH zone before combining them.

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.

Current municipal rule checkpoint

Abbotsford Zoning Bylaw 2400-2014, section 140.8 (updated January 2026), establishes permission for one secondary suite in single-detached dwellings generally, subject to zone-specific restrictions. Do not treat this as a universal one-suite ceiling: the special N44 zone expressly allows up to two secondary suites under its separate section 844 rules. Legal suites require municipal registration, Building Code compliance and permits, and the applicable mapped zone must be checked.

Source review: October 9, 2026. This is an informational bylaw checkpoint, not a parcel-specific approval. Verify enacted amendments, zone maps, registered title constraints, servicing and permits with the municipality.

How this guide was verified

Guide verification: Targeted official-source check (12 October 2026). The key claim below was compared with a linked primary municipal source; this is not a complete up-to-date bylaw, zoning-map or parcel approval review.

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

Abbotsford N44 special zone, section 844 (two-suite exception) ↗

Primary-source check · 12 October 2026: One suite is permitted in all single-detached dwellings by general clause, but special-zone N44 explicitly accommodates two in its use-specific provisions; registration and permits required.
