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.

Short answer

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

Arizona

Except 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

Arizona

Unless 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

Arizona

Unless 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

Arizona

After 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.

Source: A.R.S. 33-1804(E)(2); 33-1248(E)(2)

Irrigation backflow

Phoenix

Irrigation 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.

Separate landscape meter

Phoenix

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

Community pool fill lines

Maricopa County

A 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.

Shared sewer to the main

Phoenix

The 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.

Condo or planned community: the statute decides the starting point

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.

Who pays when the shared line fails

A.R.S. 33-1255 sets the default billing rules for condos. Costs for a limited common element go to the units it serves. A cost that benefits fewer than all units goes to those units. And if an owner's misconduct caused the expense (for example, an owner's contractor cutting into a common line), the association can assess that cost to that one unit. The declaration can change the first two defaults; the misconduct rule stands on its own.

Access is part of the deal. Under A.R.S. 33-1247, owners must let the association through their unit on reasonable notice to reach common plumbing, and whoever caused damage during that access pays to fix it promptly.

Shared sewer lines and the public main

Phoenix City Code 28-5.1 makes the property owner (or the owner's contractor) responsible for the sewer connection from the building to the public sewer. The city only steps in for single-family and duplex properties with a break in the public right-of-way. Whoever owns the shared line in a condo complex or townhome community, often the association, is on the hook for the whole run, including sections under the street, with a city permit. When a condo project goes through Maricopa County subdivision review, the county also requires covenants that provide for maintaining the water and sewer piping serving common areas.

Roots and grease in shared laterals are the usual culprits. A camera run shows where the problem sits and whose line it's in. That answers the who-pays question with footage instead of guesses. More on who is responsible for the sewer line in Phoenix.

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.

Anything else, call (602) 675-1555.

In Phoenix, who is responsible for the sewer line to the city main?

You are. In Phoenix, the property owner is responsible for the sewer line from the house to the public main, under City Code Chapter 28. The one exception: for single-family and duplex homes, the city repairs broken sewer piping in the public right-of-way. A clog in your line is always your cost.

Utility easement vs right-of-way: who can dig to fix my sewer?

A utility easement is a strip on your land where a utility may run its lines. A public right-of-way is public land controlled by the city. To dig in either to fix a sewer line, you need a city permit, an Arizona 811 locate, and the right contractor license, like an ROC A-12.

How do I maintain my sewer line to prevent backups?

Keep grease and wipes out of the drain, flush only toilet paper, keep trees and large shrubs away from the line and cleanout, act on slow drains early, and get a camera look at older lines. Grease, debris and roots cause nearly all reported sewer blockages.

Do I need a backflow preventer and annual test for my sprinklers in Arizona?

Yes. An in-ground sprinkler system is a cross-connection, so Arizona requires a backflow preventer on it. Under A.A.C. R18-4-215, a testable assembly must be tested at least once a year, and after any install, repair, or move, by a certified tester.

My backflow assembly failed its test. What happens next?

The assembly has to be repaired or replaced, retested by a certified tester, and a passing report filed with your water provider by its deadline. Most failures are fixed by cleaning or rebuilding the check valves or relief valve. Mesa wants repairs done by the compliance date, and Scottsdale gives 45 days after its notice.

What happens if I miss my Phoenix backflow test deadline?

Under City Code 37-146, Phoenix can shut off your water after 10 days written notice, or right away if your system could be a health hazard. It can also add up to 1,000 percent to your water charges per billing period. Service comes back only after the test is done and you pay the city's costs and penalties.

Read full answer: What happens if I miss my Phoenix backflow test deadline?
Why won't my sprinkler system shut off?

A zone that keeps running almost always has a stuck valve. Debris under the rubber diaphragm, a torn diaphragm, an open manual bleed screw, or a failed solenoid keeps it open. Shut the irrigation isolation valve or the backflow shutoffs to stop the water now, then clean or replace the bad part.

How do I find a leak in my pool's underground plumbing?

First rule out Phoenix evaporation with a 24-hour bucket test. If the pool drops more than the bucket, you likely have a leak. Use a dye test for shell and fitting cracks, but buried pipe leaks need a pro to pressure-test each line to find the break.

How do I legally drain or backwash my pool in Phoenix?

In Phoenix, pool and spa water and filter backwash must go to the sanitary sewer through your home's sewer cleanout, not the street, alley, gutter, or storm drain. Discharge at about 12 gallons per minute. No cleanout? A permit is required.

Read full answer: How do I legally drain or backwash my pool in Phoenix?
What size gas line does a pool heater need?

A pool heater's gas line size depends on its BTU rating and the pipe length from the meter. A 400,000 BTU natural gas heater burns about 400 cubic feet an hour: usually 1-1/4 inch pipe on short runs, 1-1/2 or 2 inch on long ones. The meter must carry the whole load too.

Read full answer: What size gas line does a pool heater need?
How do I plan a water shutoff for my commercial building?

Plan a commercial water shutoff by locating and labeling every valve first, then isolating only the affected zone so the rest of the building keeps service. Schedule it after hours, notify staff and tenants in writing, coordinate the fire line and equipment, relieve pressure, and verify backflow on restart.

Read full answer: How do I plan a water shutoff for my commercial building?
Why is my water bill so high when I can't find a leak?

A high bill with no visible leak almost always means a hidden one. The usual culprits are a silently running toilet, an underground irrigation leak, a slab leak, or a dripping fixture. Use the water-meter test and a toilet dye test to confirm, since the EPA says the average home wastes more than 9,300 gallons a year.
