What can change the price in Casas Adobes?
Switching fuel means a full permit. Electric to gas needs the heater's BTUs and a gas line drawing (meter, pipe size, pipe length). Gas to electric needs a load calculation showing the home's electrical service can handle the new heater, plus where the disconnect goes. The ACT route only works if size and fuel stay the same.

LOCAL CONDITIONS
What’s different in Casas Adobes.
Metro Water's hardness varies by neighborhood system
Metro Main covers roughly Lambert Lane to River Road, between Thornydale Road and First Avenue/Oracle Road. Its 2025 map lists hardness from 52 ppm (Hardy system) to 130 ppm (Loma and Moore-Herb Johnson systems).
Metro Water District: Hardness / TDS / Fluoride (2025 maps) ↗ · Metro Water District: Service Area Maps ↗
What the County inspector checks
For a replacement, Pima County checks for a drain pan where needed, exhaust vents that are connected and supported, a temperature/pressure relief valve in the right spot with a matching rating, a proper discharge pipe from that valve, and supported gas lines.
Certified contractors can skip the County inspection
Pima County, Tucson, Sahuarita and South Tucson back the ACT replacement program. A certified contractor buys a $22.50 water heater permit online, and no local inspection is needed because the contractor's technicians are tested and certified instead. It only covers same-size, same-fuel replacements.
