What is the cost of a building permit in Ottawa?

Building permit costs in Ottawa vary significantly based on your project scope, ranging from $100 for simple permits to over $5,000 for major renovations or additions.

The City of Ottawa uses a tiered fee structure based on construction value and complexity. Here's what you can expect to pay in 2024-2025:

Simple Permits:

• Deck construction (under $5,000 value): $100-200


• Fence installation: $100-150


• Small shed or accessory building: $150-300


• Minor interior renovations: $200-400

Mid-Range Permits:

• Bathroom renovation: $300-800 depending on scope


• Kitchen renovation: $400-1,000 depending on structural changes


• Basement finishing: $500-1,200 based on square footage


• Windows and door replacements: $200-500

Major Permits:

• Home additions: $1,000-3,000+ based on size and complexity


• Secondary dwelling units: $1,500-4,000 depending on requirements


• Structural modifications: $800-2,500


• New construction or major renovations: $2,000-5,000+

The City calculates fees using a combination of base permit costs plus additional charges based on construction value (typically 0.5-1% of project cost). For example, a $50,000 kitchen renovation might have a $400 base permit fee plus $250-500 in value-based charges.

Processing Times and Additional Costs:
Simple permits typically process in 10-15 business days, while complex projects requiring plan review can take 4-8 weeks. Rush processing is available for an additional 50% fee if you need faster turnaround.

Don't forget that electrical and plumbing work often requires separate permits from ESA (Electrical Safety Authority) and may need TSSA approval for gas work, adding $100-300 to your total permit costs.

Important Note:
Permit fees are just the beginning - factor in inspection costs and potential plan revision fees. The City requires multiple inspections throughout construction, though these are typically included in your permit fee. However, if inspections fail and re-inspections are needed, additional fees may apply.

Always get your permit cost estimate before finalizing contractor quotes, as some contractors include permit costs in their pricing while others expect you to handle permits separately.
