Permits, Requirements, and Safety


Attention Homeowners! Cities and counties in Arizona require that you obtain a permit when replacing your water heater, furnace, or air conditioner. We've heard too many scenarios where a licensed contractor has said otherwise; so, let me repeat…

A permit is required to install a new water heater, furnace, or AC unit.

If a contractor is reluctant to “pull a permit”, chances are they are cutting corners on your installation. Please be wary! It’s your responsibility as a homeowner to insist that your contractor permit the installation. Why? If there is no permit on record, you may be held liable should an insurance claim be submitted in the unfortunate case of fire or flood related to your installation. 

While permits can prevent expensive damages, they are also for your health, safety, and welfare.


An “over-the-counter permit” is a requirement of the City of Flagstaff, surrounding cities, and Coconino County residents, to ensure that a minimum safe standard is met. By inspecting your new appliance and verifying that it is installed correctly, to code, and per the manufacturer’s specifications, you’ll know that there are no corners cut and your equipment will function as intended.


When your equipment is installed properly and to current code requirements, not only will it perform optimally, it will last longer and prevent extra strain on your plumbing, heating/cooling, gas, or electrical system. And, don’t forget that Natural Gas and Propane appliances are not something that you want to hope were installed correctly.  We cannot stress this enough – use a licensed professional, make sure that a permit is pulled, and that the inspection takes place shortly after the installation.  


A licensed professional who pulls a permit and has their work inspected can actually save you money in the long run on appliance repairs or replacements. Insist that your plumber or HVAC person pulls a permit for your job to ensure that the work is done correctly and is safe for you and your family. Peace of mind is priceless, and properly permitted work is key when it comes time to sell your home.

At Your Plumber we pride ourselves in following the guidelines of the International Building Codes adopted by the State of Arizona and local jurisdictions, and we provide all of the information needed for permitting and to schedule your inspection.
