Summary

Chandler enforces the 2024 International Plumbing Code and requires a permit for plumbing work, but Section 29-2.11 exempts a short list of like-for-like swaps on single-family homes, water softeners, solar pool heaters, and electric water heaters, as long as the replacement matches the old unit's capacity and location.

Plumbing: 3. Replacement of water conditioning or treating equipment affixed to Group R-3 occupancy where the replacement equipment is of equal or lesser treatment capacity and is placed in the same location as the existing equipment. 4. Replacement of solar pool and spa heating equipment serving a Group R-3 occupancy where the replacement equipment is of equal or lesser heating capacity and is placed in the same location as the existing equipment. 5. Replacement of electric water heating equipment affixed to a Group R-3 occupancy where the replacement equipment is of equal or lesser amperage rating and is placed in the same location as the existing equipment. 6. Special cases as allowed by the Building Official for work of a similar nature and complexity as those items listed above.

Full Breakdown

7, with a table running from a 750-gallon interceptor at 0-21 drainage fixture units up to 3,000 gallons at 308-342 DFUs). 11's amendment to 'Work exempt from permit': for Group R-3 (single-family) homes, a homeowner can replace water conditioning or treating equipment 'where the replacement equipment is of equal or lesser treatment capacity and is placed in the same location,' replace solar pool or spa heating equipment on the same equal-or-lesser, same-location basis, or replace electric water heating equipment 'of equal or lesser amperage rating' in the same spot, all without pulling a permit.

Item 6 lets the Building Official extend the same treatment to comparable special cases. A new fixture, a gas water heater swap, a relocated line, or higher-capacity equipment falls outside these exemptions and needs a permit reviewed by Development Services under the adopted IPC.

Violations & Fines

Plumbing work performed without a required permit is enforced the same way as any Chapter 29 violation: a Class 1 misdemeanor under Section 29-1.3(B)(1), punishable by a fine up to $2,500 for an individual or $20,000 for a legal entity, up to six months' imprisonment, up to three years' probation, plus the building official's stop-work and abatement authority under Section 29-1.3(C).

Frequently Asked Questions

Do I need a permit to replace my water heater in Chandler?
Not if it's an electric water heater on a single-family home replaced with equal-or-lesser amperage in the same location. Section 29-2.11 exempts that swap. A gas water heater replacement, a capacity increase, or relocating the unit falls outside the exemption and needs a permit.
What plumbing code applies in Chandler?
The 2024 International Plumbing Code, adopted by reference in Section 29-4, with the model code's administration chapter replaced by Chandler's own Chapter 29 permitting rules and local amendments to fixture substitutions and grease interceptor sizing.
Can I replace a water softener without a permit?
Yes, if it's a like-for-like swap: Section 29-2.11 exempts replacing water conditioning or treating equipment on a Group R-3 home when the new unit has equal or lesser treatment capacity and sits in the same location as the old one.
