Quick answer: Fountain Hills Building Safety handles AC permits through the TOPPS online system, under the 2024 codes adopted for applications from September 1, 2025. HOA approval is separate.
If you are replacing an air conditioner, heat pump or furnace in Fountain Hills, the Town’s Building Safety division decides what permits apply. This guide explains how the process works so nothing surprises you.
Who handles it
Fountain Hills Building Safety works out of Town Hall at 16705 E. Avenue of the Fountains. Phone lines are 480-816-5123 and 480-816-5177. Plan review, phone and counter help are available 7 a.m. to 6 p.m. Monday through Thursday.
Applying online
The Town uses TOPPS, its Online Permitting and Planning System, for building applications. Contractors and owners register an account, submit the application and, once a permit is issued in TOPPS, schedule inspections through it as well. Inspections run 7 a.m. to 4 p.m., Monday through Friday.
Which codes apply
For applications received on or after September 1, 2025, the Town adopted the 2024 International Mechanical Code, International Residential Code, International Energy Conservation Code and International Fuel Gas Code, along with the 2023 National Electrical Code. New equipment and any duct, gas or electrical changes are inspected to those standards.
What we do
- Confirm with Building Safety whether your specific job needs a permit.
- Pull the permit in TOPPS when required and include the fee in your quote.
- Schedule the inspection and meet the inspector.
- Give you the final inspection record for your files.
HOA approval is separate
Many Fountain Hills communities, especially gated golf communities, have design rules about where equipment goes and how it is screened. A town permit does not replace HOA approval.
Why it matters
Permitted work is inspected, documented for future buyers, and less likely to cause trouble with insurance claims or home sales.
