How to Apply for a Permit in Toronto
Step 1: Prepare Documentation
- Site plan showing your property and proposed work location
- Floor plans (before and after) to scale
- Structural drawings (if removing walls) — prepared by a licensed engineer
- Specifications for materials and methods
Step 2: Submit Application
- Online: Toronto's Application Submission Tool (AST) at toronto.ca/building-permits
- In person: City of Toronto Building Division offices
- Through your contractor: Most experienced contractors handle this for you
Step 3: Pay Fees
| Permit Type | Toronto Fee | Processing Time |
|---|---|---|
| Building permit (residential) | $200–$2,000+ | 10–30 business days |
| Plumbing permit | $100–$500 | 5–15 business days |
| Electrical permit (ESA) | $100–$400 | 5–10 business days |
| Mechanical permit | $100–$300 | 5–15 business days |
| Secondary suite permit | $500–$3,000+ | 30–90 business days |
Step 4: Inspections
- Inspections are required at specific stages (framing, rough-in, insulation, final)
- Book inspections 48+ hours in advance through 311 or toronto.ca
- Do not cover up work before the inspector signs off — you will have to tear it out
- Multiple inspections are normal — a basement apartment may require 5–8 inspections

What Happens if You Skip the Permit?
During Renovation
- Stop work order — City inspector can shut down your project
- Fines — $500–$50,000 per offence under the Building Code Act
- Forced demolition — City can require you to tear out unpermitted work
When Selling Your Home
- Home inspection flags it — buyers' inspectors look for permit history
- Title search reveals it — buyers can walk away or demand price reduction
- Insurance issues — home insurance may deny claims related to unpermitted work
- Mortgage issues — lenders may flag unpermitted secondary suites
Real-World Consequences
- A $2,000 permit saves you from a $20,000–$50,000 problem when selling
- Unpermitted basement apartments create legal liability for fire safety
- Insurance companies are increasingly checking permit records after claims
How Your Contractor Should Handle Permits
A good contractor:
- 1. Tells you upfront which permits are needed
- 2. Prepares or coordinates all documentation
- 3. Submits applications and pays fees (included in contract price)
- 4. Schedules all inspections at the right stages
- 5. Obtains the final inspection sign-off before final payment
