In Ottawa installing an air conditioning unit or a heat pump does not require a building permit.
Zoning still governs where the outdoor unit may sit. Exempt from a building permit still means the work must comply with the Ontario Building Code and any applicable law, such as the Zoning By-law.
Designated heritage buildings and properties inside a Heritage District Overlay are not covered by these exemptions, and the City asks owners to confirm with a Building Client Service Centre before starting.

Common questions
Hiring in Stittsville
Stittsville is a growing community on Ottawa's western edge, next to Kanata. It combines an older village core with fast-expanding subdivisions like Fairwinds and Jackson Trails. New builds here drive steady demand for decks, fences, landscaping, and basement finishing, while the older village homes need roofing, windows, and renovation work. The businesses below serve Stittsville and the far west end.
A furnace or heat pump that is oversized short-cycles and wears out early. A good Ottawa installer does a heat-loss calculation for your home rather than matching the old unit's number.
Cold-climate heat pumps now work through Ottawa winters and can cut energy costs. Rebate programs change year to year; ask which current federal or provincial rebates your project qualifies for.
