Published fee information

Toronto's Building Permit Fees effective Jan. 1, 2026 list a $6.20/m² service index for stand-alone 'Basements - Finishing - in Dwellings/Townhouses', calculated using the floor area affected by the proposed work, subject to the $214.79 minimum building-permit fee where a permit is required. This finishes-only rate does NOT price a new secondary dwelling unit, structural work, plumbing/HVAC permits, underpinning or changes of use. Additional applicable fees, zoning/design and inspections must be confirmed by Toronto Building. Source: City of Toronto, Building Permit Fees, sections Fee Calculations and E (reviewed Oct. 20, 2026).

Use this as a municipal-fee reference, not as the total project budget. Design, engineering, related applications and construction costs are separate.

Scope before arithmetic

Make sure the fee belongs to your project.

Finishes alone are different from structural changes, plumbing changes, new entrances, bedrooms, fire separations or creating a second suite. The scope determines the regulatory path.

Simple finishingMay be permit-exempt

Toronto says finishing a basement can be permit-exempt when there are no structural/material alterations, no added dwelling unit and no new plumbing.

Structural/material changesPermit required

Toronto lists structural or material alterations as permit-required work.

New basement entranceRequires separate review

Entrances can trigger structural, zoning and safety considerations.
