Building Permit & Code Compliance in Saint John, NB
Saint John property owners ask us about building permit and code compliance more than almost anything else in this category — usually after a requirement they never knew existed surfaced at the worst moment.
Building permits are municipal, but the obligation is universal: structural work, additions, most basement apartments, decks beyond thresholds, and structural or use changes need a permit everywhere in Canada. Unpermitted work is the single most common compliance problem in Canadian real estate — and municipalities have well-worn processes for fixing it that most owners simply never learn.
How it works in New Brunswick
New Brunswick frames this under the National Building Code as adopted under the Building Code Administration Act. In practice, the standards your documentation must meet come from the municipal building department — and meeting them first time is exactly what our partners are for.
Building Permit & Code Compliance for Saint John properties
Local knowledge changes the job. In Saint John, the uptown’s brick heritage blocks and Canada’s oldest continuously occupied housing stock keep facade, fire escape and hazmat files constant, and the city enforces a vacant building program.
Typical Saint John clients for this service: landlords answering municipal or insurer letters, buyers in due diligence, condo boards keeping their statutory calendar, and business owners fitting out or renewing leases.
Legalizing existing work
The typical path: a designer or engineer documents the as-built condition, drawings are submitted for a permit “as constructed,” the municipality inspects (sometimes requiring targeted openings to view structure), deficiencies are corrected, and the permit closes. For basement apartments, this merges with second-unit registration where your municipality runs one. The outcome is a closed permit that ends the issue for every future sale.
The process
For a property in Saint John, expect the process to run like this:
- Tell us what was built, when, and whether the municipality is already involved.
- A designer/engineer documents as-built conditions and prepares drawings.
- The permit application is filed and municipal review managed.
- Inspections are scheduled; corrections arranged with local trades.
- The permit closes and you receive the municipal record.

Frequently asked questions
What does legalization cost?
Drawings and permit fees typically run $2,000–$8,000 for residential projects, plus whatever corrections inspections require. Complex structural work needs an engineer, which adds to that.
Do I need a permit for my deck/shed/fence?
Thresholds vary by municipality — commonly decks over 600 mm high and sheds over 10–15 m² need permits; fences usually only need by-law compliance. We confirm your municipality’s numbers before you build.
Who enforces building permit and code compliance requirements in Saint John?
In Saint John the front line is municipal — building department, fire prevention, by-law enforcement — backed provincially by the municipal building department under the National Building Code as adopted under the Building Code Administration Act. We prepare files to satisfy whichever level is asking.
