Find the right local answer
Identify the city or county responsible for building permits at your property. Describe the existing heater, proposed replacement, fuel, location and any planned electrical or venting changes. Ask which permits, plans and inspections apply.
If you live in a condominium, managed building or other shared property, also ask the responsible property manager about access, shutdowns and approval arrangements. Those arrangements do not replace public permit requirements.

Our California guide explains the current state energy-code starting point and a documented San Diego permit example. It also lists the details to have ready when contacting your own building department.
That guide is information for homeowners, not a claim that this website operates an installer network in every California city.
City guides with different local decisions
- San Diego: replacement versus tankless permit routes
- Sacramento: permits, virtual inspections and SMUD eligibility
These guides describe the named city’s process. Confirm the property’s jurisdiction and any separate utility conditions.
Outside California
The same questions are useful throughout the United States, but the answers can differ. Ask who handles plumbing, gas and electrical permits, whether replacement and relocation use different processes, and when an inspection is required.
- Who checks requirements for this exact address?
- Who obtains the permit and pays its fees?
- Are any plans or equipment specifications required?
- Who schedules inspection and records completion?
- How are additional requirements handled in the quote?
