Confirm whether a permit is required

Verify zoning compliance

Check your property's zoning using Hamilton's interactive zoning map. Confirm setbacks, lot coverage, and height limits before investing in architectural drawings.

Check for heritage designation

Look up your address on Hamilton's heritage registry. Hamilton has seven Heritage Conservation Districts including Durand-Markland, Westdale, and Ainslie Wood. If your property is designated or in an HCD, exterior changes need Heritage Planning approval.

Questions fréquemment posées

When do I need a building permit in Hamilton?

Under the Ontario Building Code, a permit is typically required for structural changes, additions, finished basements that add habitable space, decks more than 600 mm above grade, new plumbing, HVAC installations, and demolitions. Cosmetic changes like paint, flooring, and like-for-like fixture replacements generally do not. Contact Hamilton's Building Division at 905-546-2720 to confirm.

How do I apply for a building permit in Hamilton?

Hamilton accepts online building permit applications through the ePLANS portal. You will need a site plan, floor plans, structural drawings (where required), and energy efficiency compliance documentation for housing. The minimum permit fee is $291.

How long does it take to get a building permit in Hamilton?

Hamilton has a 10 business day issuing policy for complete applications without outstanding issues. After submitting via ePLANS, the Building Division pre-screens applications within 2 business days to confirm completeness. Incomplete applications will require resubmission.

What is the Niagara Escarpment Commission and do I need their approval?

The Niagara Escarpment Commission (NEC) regulates development within the Niagara Escarpment Plan Area, which includes significant portions of Hamilton. If your property is in this area, you need a Development Permit from the NEC in addition to your municipal building permit. Use the NEC's interactive map to check if your property is affected.

Do I need Conservation Authority approval in Hamilton?

Hamilton is covered by three Conservation Authorities: HCA, NPCA, CH. If your property is in a regulated area (near watercourses, wetlands, flood plains, steep slopes, or the Lake Ontario shoreline), you may need their approval before the city can issue your building permit.

Is my Hamilton property in a Heritage Conservation District?

Hamilton has seven designated Heritage Conservation Districts: Durand-Markland, Hamilton Beach, MacNab-Charles, St. Clair Boulevard, Cross-Melville (Dundas), Ainslie Wood, and Westdale. If your property is individually designated or in an HCD, exterior alterations need Heritage Planning approval in addition to a building permit.

Do I need an ESA permit for electrical work in Hamilton?

Yes. The Electrical Safety Authority (ESA) requires a notification for all electrical work in Ontario, regardless of municipality. Homeowners can file ESA notifications for work on their own home, or hire a Licensed Electrical Contractor (LEC). This is separate from your municipal permit.

Do I need a TSSA permit for gas work in Hamilton?

Gas work (furnaces, gas fireplaces, gas lines, BBQ hookups) must be performed by a TSSA-certified gas technician with G1 or G2 certification. TSSA-certified contractors handle the regulatory notification and inspection process for you.
