Legal Basement Permit
PermitsHub handles your legal basement permit application, drawings, zoning compliance, and City approvals in Toronto.
Scope of service.
A legal basement permit is required when you convert an unfinished basement into livable space, add a second suite, or create a separate rental unit in your Toronto home. This permit ensures your basement meets Ontario Building Code requirements for ceiling height, egress windows, fire separation, electrical, plumbing, and HVAC systems. Without a legal permit, your basement suite cannot be legally rented, may fail a home inspection during resale, and could result in fines or orders to remove the work. In Toronto and the GTA, legalizing a basement involves building permit approval and often zoning review to confirm your property allows a second unit. PermitsHub prepares the required drawings, navigates zoning restrictions, submits your application to the City, and manages the approval process so your basement conversion is fully compliant and insurable.
