Do You Need a Permit for a Basement Walkout?

Yes. A basement walkout or separate entrance usually requires a building permit. Basement walkout projects typically require structural engineering review and stamped details because the work may affect foundation walls, exterior stairs, drainage, guards, and structural openings. Permit Works coordinates the required drawings and supports the city review process.

“From the first point of contact to getting permit approvals, Permit Works was very professional and responsive. They created a frictionless customer experience for what is typically a frustrating and long process to obtain permit approvals from the City of Toronto.”

"It has been great working with Permit works on multiple projects that I have brought them on for. They are very well organised and fast in their deliverables. As a general contractor I wish most companies were like them. Saveska Construction will continue to use them in the future."
