How do I apply for an interior-renovation permit for my Toronto house?

Toronto provides a residential interior-alteration application route for detached houses, semi-detached houses and townhouses. The drawings must explain the existing building and proposed work.

Application steps

  1. Confirm the residential interior-alteration guide fits your building and work; party-wall projects require applications for the affected properties.
  2. Prepare dimensioned floor plans, sections and construction details. Show existing and proposed uses, structural work, fixtures and alarms.
  3. Include a site plan when creating a second suite or new openings.
  4. Complete the construction application, applicable designer or engineering forms, and Rental Renovation Licence Screening Form; prepare PDFs.
  5. Follow Apply for an Interior Alterations permit on the official page to submit through Toronto Building Online Services. Related mechanical, plumbing and drain applications can follow.
  6. Respond to intake requests for corrected or missing documents before examination proceeds. Review the current permit fees.

Before you open the official service

What to check for your situation

This route does not replace property-specific review or establish that proposed work is exempt from other permits or licensing.

Fees, processing times and document rules can change. This page helps you navigate; it does not confirm eligibility or replace the government’s instructions.
