Money-Saving Tips
Apply early — GTA permit wait times are 4-12 weeks depending on municipality and complexity.
Complete applications get processed faster — incomplete submissions restart the clock.
Permit expediting services cost $1,500-$5,000 but can save weeks of construction delays.
Some minor work (painting, flooring, fixtures) doesn't require a permit — check before paying.
Keep all permit documents — you'll need them when selling the property.

Building Permits Cost FAQs
What needs a building permit in Ontario?
OBC Part 1.3.3 requires permits for new construction, structural alterations (load-bearing walls, beams), additions, change of use (garage to living space), demolition, plumbing, and HVAC. Electrical work needs a separate ESA permit. Cosmetic work (paint, flooring, cabinets) and like-for-like replacements (same-size water heater, furnace) are exempt. Most municipalities exempt decks under 24 inches above grade. Check local bylaws.
How long does it take to get a building permit?
Plan review takes 4-8 weeks in Toronto, 2-4 weeks in smaller municipalities. Add 2-6 weeks before that to prepare drawings and structural letters. Total timeline from starting drawings to permit in hand: 6-14 weeks. Projects requiring zoning variances add 3-4 months.
Can I apply for a permit myself?
Yes, but most homeowners hire professionals. You need detailed drawings (floor plans, elevations, sections, site plan), structural calculations from a P.Eng for load-bearing changes, and code compliance notes. Incomplete applications get rejected without review. Designers and contractors prepare better permit packages and handle revisions faster.
What happens if I build without a permit?
Municipalities can issue stop-work orders, fine you $500-$5,000 per day, or force you to demolish non-compliant work. Insurance may refuse to cover unpermitted work. When you sell, title search reveals missing permits — buyers demand retroactive permits (2-3× normal cost) or reduce their offer. Inspectors can require you to open up walls to verify hidden work.
How much does a building permit cost?
Toronto charges $10 per $1,000 construction value (minimum $100). A $50,000 basement renovation is $500 in permit fees. A $150,000 addition is $1,500. Smaller municipalities charge less — often flat fees or lower rates. Add drawing fees ($2,000-$8,000) and structural engineering ($1,500-$5,000). Total cost to permit a typical project: $2,000-$7,000.
