How long building permits actually take in Ottawa

What the Building Code actually requires

Ontario's Building Code sets maximum review periods that apply to every municipality, Ottawa included. The clock starts when a complete application is received — not when an application is submitted.

A typical custom home falls in the 10 day category; multi-unit and commercial work lands in the longer windows.

Building Code Act, 1992 and O. Reg. 332/12, Division C, s. 1.3.1.3

The clock is not the schedule

• An incomplete application never starts the clock. Missing drawings, an unsigned form or an unresolved zoning issue means the review window has not begun, however long the file has been sitting there.
• Deficiency letters reset your schedule. Each resubmission loop costs days to weeks. The review restarts; your trades do not.
• Zoning problems surface late. Setbacks, height, lot coverage and infill rules are knowable before you apply. Discovering them in review is the expensive way.
• Other approvals run on their own clocks. Committee of adjustment variances, site plan control and conservation authority sign-offs precede or parallel the permit, and none of them are bound by these windows.

Keeping permits off the critical path

• Resolve zoning questions at intake, before the design is finalized.
• Submit complete: a submission checklist per building class, enforced every time.
• Track review status and deficiency responses like tasks with owners and due dates, not like emails.
• Book inspections against the construction schedule rather than after the fact.
