Most heat pump installations need an electrical permit, and many need a mechanical (HVAC) permit too. Here’s what to check, plus how solar permits compare.
Most homes need at least one heat pump permit. Installing a heat pump usually involves new electrical wiring, so an electrical permit is common. Many municipalities also require a mechanical (HVAC) permit for installing or altering heating and cooling equipment, and some have rules about where the outdoor unit can go. The exact requirements depend on your municipality, so confirm them before work starts.
| Permit or approval | When it’s usually needed | Who usually applies |
|---|---|---|
| Electrical permit | When a new circuit or electrical work is needed, which is common | Licensed electrical contractor |
| Mechanical (HVAC) permit | When installing or altering heating, ventilation or air-conditioning equipment, in many municipalities | HVAC contractor |
| Building permit | Sometimes, for structural work such as a new wall mount, platform or major duct changes | Contractor |
| Location or setback approval | If the outdoor unit would sit closer to a property line than zoning allows | You or your contractor |
Heat pump permit rules differ, but official city pages show the pattern:
Check your own municipality’s building department, or ask your contractor to confirm the requirements in writing.
Solar projects usually need more approvals than a heat pump because they connect to the grid:

If you’re doing both at once:
Unpermitted work can lead to orders to correct it, problems with insurance claims or a home sale, and missed safety issues. Some incentive programs also ask for proof that work was done by qualified contractors with the required permits.
Our guide to contractor certifications in Canada explains what to look for.
Plan on an electrical permit for most heat pump installations, and check whether your municipality also requires a mechanical permit or has placement rules. Solar adds utility approval and often a building permit. Either way, have your contractor confirm the heat pump permit requirements in writing before work starts.
Often yes. Many municipalities require a mechanical permit for installing or altering heating and cooling equipment, and an electrical permit if wiring changes. Check with your municipality.
It’s not recommended. Refrigerant work requires certified technicians, and some cities only issue mechanical permits to licensed contractors.
Usually. It needs electrical work and refrigerant lines, and many municipalities treat it like any other heating and cooling installation.
