Do I need a permit for hvac replacement or installation in Gilbert?
Yes. In Arizona, hvac replacement or installation generally requires a permit, and Gilbert is no exception.
Most Arizona jurisdictions require a mechanical permit to change out an air conditioner, heat pump, or furnace, even for a like-for-like swap; the specific permit type and inspections depend on the local adopted code. Adding a new electrical circuit or gas line for the equipment, or relocating it, can trigger additional electrical, plumbing, or structural review. Gilbert treats HVAC installations and changeouts, including ductwork and venting changes, as permitted mechanical work, so plan on a residential permit through the One Stop Shop portal rather than assuming a like-for-like swap is exempt. Confirm current mechanical and electrical requirements with Development Services at (480) 503-6700, since Gilbert enforces its own adopted 2018 International Codes with local amendments. All residential except fire permits are submitted, paid, and scheduled online through Gilbert's One Stop Shop portal. A new or relocated system, or one that burns gas, goes beyond a like for like change out and is not covered by replacement exemptions. Gas piping and venting normally require their own permit and a pressure test, and a relocated system usually triggers new duct, condensate, and electrical disconnect requirements.
