Basement apartments and secondary suites in Hamilton

Legal basement apartments and in-law suites, planned around Hamilton's permit and fire-separation rules.

A self-contained suite can house a parent, an adult child or a tenant, and it can change the numbers on your mortgage. It also has to meet the Building Code: fire separation, smoke and CO alarms, egress windows, ceiling heights and a separate entrance.

We build secondary suites as one complete project: kitchen, bathroom, bedroom, laundry and every code requirement in between. We'll also point you to the City of Hamilton and federal programs that can help fund it.

Fantastic experience from start to finish. Professional, reliable, and detail-oriented throughout the entire renovation process. Communication was great, timelines were agreed upon prior to work commencing, and the workmanship exceeded expectations.

Good to know

Yes, secondary dwelling units are permitted in many Hamilton homes, but they need a building permit and must meet fire and building code requirements. We'll check your property and plan to the rules.
