Building Permits

Do I need a building permit to have a Furnace or
Air Conditioner or ductwork installed in my home?

Building permits are required when you install new, or replace an existing, furnace (and/or) any refrigerant containing component (and/or) more than 40 feet of system ducts.

  1. It's the LAW - Every licensed HVAC Contractor in California knows that building permits are required for installations or replacement of HVAC equipment or ductwork. Simple repairs do not require permitting.  If your contractor tells you otherwise, they are either lying, incompetent or unlicensed. Show them the door.
  2. Trust but Verify - The building permit system helps insure that the homeowner actually gets what they are paying for and that what is being installed is done safely & correctly.   A safety inspection will be performed by the city or county inspector and the energy efficiency inspection and testing will be performed by the HERS Rater.  
  3. Failing to permit - Very often when a contractor wants to bypass the permit process, it is because they are not capable of installing a HVAC system to code.  If disaster strikes, and the unpermitted HVAC system causes a fire, your insurance may not cover the damages. Think Illegally Installed.
  4. Selling your Home - If permits were not obtained and you sell the home in the future, you must disclose that your HVAC system was installed without permits on the seller's Disclosure Statement (Its the LAW). To complete the sale you likely will be required to obtain the permits and have the system brought up to current code which could cost you thousands of dollars.
Take Out a Building Permit Yes, a building permit is required for the installation or replacement of a heating and/or cooling system. Failing to obtain a required permit is violation of law, and risks exposure to additional cost and liability. Real estate transactions require disclosures to potential buyers about permits and Code compliance. If work was done without a permit, you may be required to bring your home into compliance with Code before selling it. Additionally, your homeowner's insurance coverage may be at risk if it is found that improvements to your home were done without a permit. Consult with your policy carrier for more information.
