Do You Need a Permit to Replace a Water Heater in California?
Getting a water heater permit is essential, required by California law, and can be obtained from your local building and safety planning office. The permit acts as a request for inspection and can help to give you guidance on the appropriate codes for your area, as well as the installation itself. These permits can cost anywhere between $50 and $400. Secondary permits could be required in the event of some major work such as a renovation.
An inspector will come to check on the installation and make sure it has been done safely and correctly.
