HOA and Condo Association Plumbing in Phoenix
Who fixes which pipe under Arizona's condo and planned community laws, plus the backflow, pool and sewer rules that land on the association.
Arizona condo law makes the association maintain the common elements and each owner maintain their unit, unless the declaration says otherwise. In Phoenix, an association also tests irrigation backflow assemblies every year, keeps community pool fill lines on an air gap or approved backflow device, and, where it owns the shared sewer line, repairs it out to the public main.
The rules that apply
Each rule links to the official text we read it from. Cities change these, so check the source before a big decision. Last checked 2026-09-29.
Who maintains what in a condo
ArizonaExcept as the declaration provides, the association maintains, repairs and replaces the common elements and each owner maintains the unit. Owners must allow access through the unit on reasonable notice.
Source: A.R.S. 33-1247(A)Lines that cross unit boundaries
ArizonaUnless the declaration says otherwise, a chute, flue, duct, conduit or other fixture partly inside a unit is a limited common element for the part serving only that unit, and a common element for any part serving more than one unit.
Source: A.R.S. 33-1212(2)Who gets billed
ArizonaUnless the declaration says otherwise, costs for a limited common element go to the units it serves and costs benefiting fewer than all units go to those units. Separately, a cost caused by an owner's misconduct can be assessed to that owner.
Source: A.R.S. 33-1255(C), (E)Emergency board action
ArizonaAfter declarant control ends, a board can hold an emergency meeting for action that can't wait for the 48-hour notice, act only on the emergency, and record the reason in the minutes. Condos have the same rule.

PhoenixIrrigation systems need a PVB, or an RP where there's chemical injection, multiple services, or elevated areas higher than six inches below the PVB. Every assembly is tested at least once a year, with records kept three years.

PhoenixNew services established after January 1, 1990 need a separate water meter for landscape watering of any landscaped area over 10,000 square feet.

Maricopa CountyA pool run by a community association is semipublic. Potable make-up water enters only across an air gap, above a float-controlled feed tank, or through a submerged inlet with an approved backflow device.

PhoenixThe owner maintains and repairs the building connection to the public sewer. The city fixes breaks in the right-of-way only for single-family and duplex properties; other owners repair off-property sections with a city permit.

Board members and community managers get the same call over and over: a pipe broke, and nobody's sure whose pipe it is. In Arizona the answer starts with what kind of association you run.
In a condominium, A.R.S. 33-1247 makes the association responsible for maintaining, repairing and replacing the common elements, and each owner responsible for the unit, except where the declaration says otherwise. A.R.S. 33-1212 fills in the gray zone. When a chute, flue, duct, conduit or other fixture sits partly inside a unit, the part serving only that unit is a limited common element for that unit, and any part serving more than one unit is a common element. A shared drain stack running through several floors usually lands on the association's side of that line. See our page on A.R.S. 33-1247 condo plumbing responsibility.
In a planned community, owners hold their own lots, and the association owns and runs the common areas under its declaration. The plumbing serving one house is usually that owner's; irrigation, pools and other common-area systems are usually the association's. Our Planned Communities Act page walks through it.
Either way, read the declaration and the community's governing documents first. They often draw the line more precisely than the defaults.
Common-area irrigation and the yearly backflow test
Phoenix requires backflow protection on irrigation systems: a pressure vacuum breaker (PVB) where there's no backpressure, and a reduced pressure (RP) assembly where there's chemical injection, multiple services, or elevated areas higher than six inches below the PVB. Every assembly gets tested at least once a year by a certified tester, with records kept three years. A community with dozens of controllers can have dozens of assemblies, so put the due dates on one calendar. See backflow preventers for sprinklers and what to do after a failed test.
Newer communities often have a dedicated landscape meter. Phoenix City Code 37-53 requires a separate meter for landscape watering of areas over 10,000 square feet on services set up after January 1, 1990. When a common-area water bill jumps, that meter is the first place to look; a valve that won't close is a common cause. Here's why a sprinkler system won't shut off.
Pools and community water shutoffs
Maricopa County treats a pool run by a neighborhood or community association as a semipublic pool. Its Environmental Health Code bans cross connections between drinking water and the pool's recirculation system; fill water has to come in across an air gap, above a float-controlled feed tank, or through a submerged inlet with an approved backflow device. Auto-fill valves and pool equipment leaks are common trouble spots. See how to find a pool plumbing leak.
Shutting off water to a building or a whole community needs notice and a plan: a valve that's been exercised, a firm window, and a crew ready to restore service. Our commercial water shutoff guide covers the steps. When a main breaks overnight, the board doesn't have to wait. A.R.S. 33-1804 (planned communities) and 33-1248 (condos) let a board hold an emergency meeting for action that can't wait for 48 hours' notice, as long as the minutes record the reason. Fix first, document after. That's it.
