Do you need a permit for hvac in Nepean?
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.
