Water Heater Permits in Apache Junction, AZ

Like-for-like swaps are often exempt inside city limits. A new fuel, a tankless conversion, or a new location is a permit. Gold Canyon is the county, not the city.

What we are Referral service, not a contractor

In most like-for-like swaps inside Apache Junction city limits, a permit is not required, provided the city conditions are met. Switching gas and electric, changing tank to tankless, or moving the heater requires a city plumbing permit, listed at $100 per dwelling in the city’s fee schedule (revised 2021; confirm the current fee). Gold Canyon and other unincorporated areas follow Pinal County rules. Always confirm with Building Safety. Last verified October 8, 2026.

Short answer

People searching “do you need a permit to replace a water heater in Arizona” get a generic yes. Apache Junction’s own code is more specific. The exemption is conditional. It is not permission to skip the T&P discharge, the pan, the vent, or the electrical bond. Call (480) 555-0199 if you want a plumber to pull whatever permit the address actually needs. This site does not pull permits.

When a permit is not required in Apache Junction city limits

City administrative code section 7-1-6(B), in the “Work exempt commentary” PDF dated March 9, 2022, lists work exempt from building permits. The fuel-gas clause says a permit is not required for:

Replacement of gas water heating appliances of equal or less Btu/cfh rating and minor modification to electrical, plumbing, mechanical and fuel gas connections necessary to serve the new appliance in one-or two-family residential homes, and manufactured homes where the venting and combustion air are compliant with current code requirements.

The plumbing clause says a plumbing permit is not required for:

Replacement of electric water heating appliances of equal or less amperage rating, where code required bonding and disconnecting means are present, in one- and two-family residential, R-1, R-2, R-3, and R-4 occupancies, manufactured homes, and park models where the appliance serves an individual dwelling unit.

Both sentences are the city’s, not a paraphrase written to win an argument. Read them in the PDF linked below. If the new heater is a higher BTU or a higher amp draw, you have left the exemption.

When a permit is required

The fee table in Chapter 4, Article 4-4, effective February 3, 2020 and revised February 1, 2021, has a line for residential water heaters when you change fuel or energy source, change type from tank to tankless, or change location. The listed amount is $100 per dwelling unit. The schedule also describes a technology fee of 2% of the permit fee and a $40 minimum administrative fee for a stand-alone MEP permit. Call Building Safety before you treat the 2021 dollar amount as this month’s fee. Applications go through the city’s Building Safety and Inspection division. The city points people to MyGovernmentOnline on its forms page.

That is the job on a water heater replacement that is not a straight swap, and on many tankless conversions.

Gold Canyon and unincorporated Pinal County

Gold Canyon, ZIP 85118, is not the City of Apache Junction. Pinal County Bulletin 003, “Permit Exemptions,” says the replacement of an electrical or gas water heater with the same type, size, and location may be permit exempt. “May be” is the county’s wording. If the heater moves or the type changes, ask Pinal County, not Apache Junction Building Safety. The service-area page separates the two geographies.

Code items still required even without a permit

An exemption from the permit fee is not an exemption from the installation. The plumber should still check venting, T&P discharge, bonding and a disconnect on electric units, an expansion tank when the system needs one, a drip pan where the location needs one, and strapping if the adopted code requires it. Your plumber confirms the strapping rule for your address.

Can I replace my own water heater in Arizona?

A.R.S. § 32-1121(A)(5) exempts an owner working on their own property when that property is not for sale or rent, within the limits of the statute. The same statute’s advertising rule is why this website says, in plain text, that it is not a licensed contractor. Doing the work yourself still leaves gas, scalding water, and electrical risk with you. If a local permit is required, the homeowner exemption does not erase it. Read the statute, then decide.

How to check a plumber’s license

Residential water heaters fall under Arizona Registrar of Contractors classification CR-37, plumbing, which covers residential and commercial plumbing. Search the contractor at roc.az.gov. Ask for the license number when a plumber is connected from this line. We do not print an ROC number on this site, because this business is not the contractor.

Permit questions

Call (480) 555-0199

Do you need a permit to replace a water heater in Arizona?

Arizona does not use one statewide yes or no. In Apache Junction city limits, many like-for-like gas and electric replacements are exempt under city code section 7-1-6(B) when the city’s conditions are met. Changing fuel, changing a tank to tankless, or moving the heater needs a permit. Gold Canyon follows Pinal County, which has its own same-type exemption. Confirm with the office that covers your address.

Do I need a permit to install a tankless water heater in Apache Junction?

A tank-to-tankless change is a change of type. The city fee table lists that work as a permitted water heater job, shown at $100 per dwelling on the schedule revised in 2021. Confirm the current fee with Building Safety. A like-for-like tankless replacement, same fuel and place, is a different question and should be asked of Building Safety with the model numbers in hand.

Am I allowed to replace my own water heater?

Arizona Revised Statutes section 32-1121(A)(5) has a homeowner exemption for owners working on property that is not for sale or rent. That statute does not cancel the city’s permit rules, and it does not make a gas or electric swap safe. Most Apache Junction owners call a plumber. If you do it yourself, you still have to meet the exemption conditions and the code items the plumber would have checked.

Does Arizona require water heater straps?

Your plumber should follow the code Apache Junction or Pinal County has adopted, including strapping if that code requires it. Do not skip strapping just because a like-for-like swap is permit-exempt.

How much is a water heater permit in Apache Junction?

The city fee table revised February 1, 2021 lists $100 per dwelling for a residential water heater when you change fuel, change type from tank to tankless, or change location. The same schedule mentions a 2% technology fee and a $40 minimum administrative fee on stand-alone MEP permits. Confirm how those fees combine, and confirm that $100 is still current, with Building Safety before you rely on it.

Does a mobile home water heater replacement need a permit?

The city’s gas and electric like-for-like exemptions name manufactured homes, and the electric clause also names park models when the heater serves one dwelling. The conditions still apply: equal or lower input, compliant venting or bonding and a disconnect. A type change or a move is permitted work. Park rules can be stricter than the city. See the mobile home guide for the housing context.
