Do you need a permit for HVAC work?
Usually needs a permit
Replacing an air conditioner, furnace or heat pump usually needs a mechanical permit, and often an electrical one, with an inspection at the end.
What to ask every contractor
- Does this job need a permit where I live?
- Who pulls it, and is the fee included in your quote?
- Who schedules the inspection, and will you be there for it?
- Will I get a copy of the final sign-off?
How to check your local rules
Search for your city or county name with "HVAC permit", or call the building department. Many publish a list of work that doesn't need a permit. Ask your HOA too — they can have their own approval process.
Questions about HVAC permits
Do I need a permit for HVAC work?
Replacing an air conditioner, furnace or heat pump usually needs a mechanical permit, and often an electrical one, with an inspection at the end. Rules are set locally, so check with your city or county building department.
Who pulls the permit for HVAC work?
Usually the contractor, and the fee is part of the quote. Ask each contractor to write it into the quote, along with who schedules the inspection.
What if a contractor says a permit isn't needed?
Ask them to show you the local rule, or call the building department yourself. A contractor who suggests skipping a required permit to save money is a warning sign.
