How long do I need from permit application to start in Ottawa?

In Ottawa, you should budget 4–10 weeks from permit application to breaking ground, depending on the complexity of your project.

For a standard basement finishing permit (framing, electrical, plumbing rough-in), the City of Ottawa typically processes applications in 10–20 business days — roughly 2–4 weeks. However, that assumes your application is complete and accurate on the first submission. Missing drawings, unclear scope, or a request for revisions can easily add another 2–4 weeks to the process.

More complex projects — like a secondary suite or basement apartment conversion — fall into a different category. These require zoning compliance review in addition to the standard building permit review, and you're realistically looking at 6–8 weeks minimum, sometimes longer if your property needs a Committee of Adjustment variance or if the City flags any zoning issues. It's not uncommon for secondary suite permits to take 8–12 weeks when all the back-and-forth is factored in.

One thing many Ottawa homeowners don't realize: you can use that waiting period productively. While your permit is in review, your contractor can be finalizing material selections, ordering long-lead items (like egress windows or steel beams), and locking in trade schedules. A well-organized contractor will have you ready to start the day the permit is issued, not two weeks after.

A few practical tips for Ottawa specifically:

• Submit through the City's online portal at ottawa.ca/building — it's faster than paper submissions
• Have a licensed designer or experienced contractor prepare your drawings — incomplete or non-compliant submissions are the #1 cause of delays
• Call Building Code Services at 613-580-2424 if you have pre-application questions about your specific project
• Don't schedule trades or order materials until the permit is in hand — working without a permit creates serious liability and insurance issues
