- PermitVerified Sep 2026Chandler Homeowner Building Permit Manual (Rev. 4/09/26), Work Exempt from PermitDo you need a permit to repipe a house in Chandler?Our reading: yes, replacing a house's water supply or drain piping needs a Chandler permit. The homeowner manual never uses the word repipe, but it says ordinary repairs, which need no permit, do not include replacement of water supply, sewer, drainage, soil, waste, vent or gas piping.
- PermitVerified Sep 2026Chandler Development Services, Inspections page; Homeowner Building Permit Manual, Inspection Scheduling (pp. 5 to 6) and Required InspectionsHow do you schedule a plumbing inspection in Chandler?Chandler lets you book a plumbing inspection three ways: the CLICS online portal, the automated phone line at 480-782-3100, or a text to 844-281-3520 with the permit number, three-digit inspection code and date. The city's manual says to request it at least one business day ahead, with the work exposed.
- City CodeVerified Sep 2026Chandler City Code 29-4 (Ord. No. 5108)What does Chandler City Code 29-4 change in the International Plumbing Code?Chandler City Code 29-4 adopts the 2024 International Plumbing Code, deletes its Chapter 1 and points to the building code's administration chapter instead, and makes two technical changes: drinking fountain substitutions (410.4) and grease interceptor sizing (1003.3.7). Every other IPC section applies as the model code wrote it.
- PermitVerified Sep 2026Chandler Homeowner Building Permit Manual, Working Without a Permit and FeesWhat happens if you do plumbing work without a permit in Chandler?Chandler can issue a Legal Notice or an Order to Comply, and the permit fee is doubled for work done without a permit. The city can also order non-compliant work removed at the homeowner's cost. Problems often surface at sale, when county records do not match and FHA will not provide a loan.
- PermitVerified Sep 2026Chandler Homeowner Building Permit Manual (Rev. 4/09/26), Room Additions and Appendix AWhat is the Chandler water meter worksheet when you add plumbing fixtures?Chandler's Homeowner Building Permit Manual asks for a water meter worksheet when you add plumbing fixtures to a room addition, and says remodels typically follow the same requirements.

The Zoning Administrator can extend that by at most 30 days for weather or acts of God. Sign permits are due before occupancy.
- Adopted CodesVerified Sep 2026Chandler City Code Ch. 29, Arts. IV, VI, VII and X (Ord.

Water Heaters
Water Heaters in every city- PermitVerified Sep 2026Chandler City Code 29-6.7 (IRC R105.2 as amended); Homeowner Building Permit Manual, Work Exempt from Permit, item 10Chandler water heater replacement permit: when you need oneUsually no permit for a like-for-like swap. City Code 29-6.7 exempts a gas water heater of equal or lesser BTU and an electric one of equal or lesser amperage, in the same location, and the homeowner manual lists like-for-like swaps as exempt. A bigger unit, a new location or new piping changes the answer.
- PermitVerified Sep 2026Chandler City Code 29-6.7 (IRC R105.2 as amended), Gas item 4 and Plumbing item 5; Homeowner Building Permit Manual, Work Exempt from Permit, item 10Do you need a permit to switch to a tankless water heater in Chandler?Chandler's pages do not say. City Code 29-6.7 exempts a gas water heater replacement only when the new unit has equal or lesser BTU capacity and sits in the same location, and no city page names tankless units. Our reading: a higher-BTU unit, a move or new gas piping falls outside that exemption.

A new line from the meter must be buried at least 12 inches below grade.

- City CodeVerified Oct 2026Chandler City Code 52-36(C) to (F) and 52-1Which backflow device does a Chandler business need?Chandler picks the backflow device by hazard, not by business type. Health hazards, auxiliary water supplies and uncontrolled cross-connections need an air gap or a reduced pressure principle (RP) assembly.
