How much does a building permit cost for a home addition in Ottawa?

Permit fees scale with declared construction value, roughly $12 to $20 per $1,000, with a minimum fee. Typical totals are $1,500-$6,000 for a single-storey addition, $4,000-$12,000 for a second-storey addition, $800-$3,000 for an attached garage, $500-$1,800 for basement work, and $3,000-$8,000 for a secondary dwelling unit.

If the design needs a minor variance, the Committee of Adjustment application is a separate fee. We show the permit fee as its own line on your quote, so you can see it apart from the build.
