How long does it take to get a building permit in Ottawa?

Building permit timelines in Ottawa typically range from 10 business days for simple projects to 8+ weeks for complex renovations, depending on the scope and completeness of your application.

The City of Ottawa Building Code Services (613-580-2424) processes permits on different timelines based on project complexity:

Simple Permits (10-15 business days):

• Decks under 24 inches high


• Fences


• Sheds under 108 square feet


• Minor interior renovations without structural changes

• Bathroom renovations


• Kitchen renovations (non-structural)


• Basement finishing


• Window and door replacements


• Interior wall modifications

• Structural modifications


• Additions


• New construction


• Projects requiring multiple trades coordination


• Secondary dwelling units (can take 6-12 weeks due to zoning compliance requirements)

The biggest factor is application completeness. Incomplete applications get rejected and restart the clock. Common delays include missing structural drawings, inadequate site plans, or unclear electrical/plumbing layouts. The City of Ottawa's Building Code Services strongly recommends having a qualified designer or architect prepare drawings for anything beyond simple renovations.

Seasonal timing matters too. Spring and early summer see higher application volumes, potentially adding 1-2 weeks to processing times. Winter applications often move faster through the system.

The Ottawa Process:

Submit your application through ottawa.ca/building or in person at City Hall. You'll receive an acknowledgment within 2-3 business days. The review process involves multiple departments - building, electrical, plumbing, and sometimes planning or heritage if your property has special designations.

Red Flags to Avoid:

Never let a contractor start work before permit approval, even if they claim it's "just preparation." Some contractors promise to "handle the permit later" - this creates liability issues and potential stop-work orders. Always verify your contractor can actually pull permits in Ottawa by checking their licensing status.

Expediting Your Application:

Consider pre-consultation services offered by the City (additional fee applies). This catches issues early and can prevent rejections. Ensure your contractor or designer is familiar with current Ottawa Building Code requirements and submission standards.
