City of Phoenix Codes: Zoning, Permits, and Short-Term Rentals

The Phoenix City Code is the collection of local ordinances the City Council has adopted to regulate property maintenance, noise, zoning, animals, pools, rentals, and construction inside city limits. The Phoenix city codes most residents run into are Chapter 39 (neighborhood preservation), Chapter 23 (noise and lighting), Chapter 8 (animals), the Zoning Ordinance, and the building permit rules — and they carry real teeth: inspectors can issue civil citations, escalate to criminal misdemeanors, and bill property owners directly when the city has to clean up a problem itself. Civil sanctions start at $100 and cap at $2,500 per offense, not counting surcharges.¹

Property Upkeep Under Chapter 39

Chapter 39, the Neighborhood Preservation Ordinance, sets the baseline for how a property has to look and function. Most citations start with vegetation. Lawn grass and weeds can’t exceed six inches. Properties must stay clear of dead trees, loose branches, dead palm fronds within ten feet of any structure or fence, and tumbleweeds.²

The same chapter bans accumulation of junk, litter, and debris on any lot, including discarded furniture and scrap. Perimeter fences and walls must stay structurally sound; leaning, collapsed, or missing sections count as violations. Graffiti visible from the street or a neighboring property has to come off within ten days of a notice of violation. If the owner doesn’t act, the city sends a crew and bills the cost back.³

Penalties escalate in a rolling 36-month window. A first violation carries a civil sanction of at least $100. A second within 36 months moves the minimum to $250. A third or later climbs to at least $500. The absolute cap for any single offense is $2,500.¹

Noise, Construction Hours, and Outdoor Lighting

Chapter 23 handles noise. Phoenix doesn’t set a single decibel threshold; instead it lists categories of disturbance and gives extra weight to sounds between 11:00 p.m. and 7:00 a.m., when loud music, shouting, and similar noise are specifically flagged as disturbing to nearby homes, hotels, and hospitals.⁴ Daytime noise isn’t automatically fine either — any sound that disturbs the comfort or repose of others can trigger enforcement.

Residential construction within 500 feet of an occupied building follows seasonal hours. From May through September, work is allowed 6:00 a.m. to 7:00 p.m. on non-holiday weekdays. From October through April, the window is 7:00 a.m. to 7:00 p.m. Weekend and holiday work is off-limits unless the Planning and Development Director grants a special permit.⁴

Outdoor lighting sits in the same chapter. Certain high-intensity fixtures must be fully shielded so light projects downward instead of onto neighboring property. The requirement applies to high-pressure sodium, metal halide, fluorescent, quartz, and incandescent bulbs over 150 watts. Fixtures with an automatic shutoff that keeps them dark from 11:00 p.m. to sunrise are exempt from the shielding mandate.⁵

Zoning: Setbacks, ADUs, and Home Businesses

The Zoning Ordinance controls what gets built, where it sits, and how tall it can be. Accessory structures like sheds, workshops, and detached garages have their own height limits: 15 feet maximum when placed in a required rear or side yard, or up to the main house’s allowed height when located outside required yards. Building beyond those limits without an approved variance triggers a modification order.⁶

Accessory Dwelling Units

Arizona House Bill 2720, signed in 2024, requires cities over 75,000 residents to allow at least one attached and one detached ADU on any single-family lot. In Phoenix, a detached ADU on a lot up to 10,000 square feet is capped at 1,000 square feet of gross floor area. Larger lots allow up to the lesser of 3,000 square feet or 10 percent of the net lot area. Attached garages, shade structures, and carports built as part of a detached ADU don’t count toward that square footage. Height in required yards caps at 15 feet.⁶ ADUs cannot be used as short-term rentals.

Home-Based Businesses

Home occupations are allowed but tightly bounded. Only family members living in the home can work in the business. No exterior signs, storage, or displays. The business cannot occupy more than 25 percent of the area under roof. Activity has to stay between 7:00 a.m. and 10:00 p.m. Odor, dust, noise, vibration, smoke, heat, and glare cannot cross property lines. Anything that generates outside traffic, operates from an accessory building, or involves outdoor use needs a separate use permit.⁷

Animals: Leashes, Barking, and Backyard Poultry

Chapter 8 governs pet ownership, and the leash rule generates most citations. Dogs must be confined on the owner’s property or controlled on a leash no longer than six feet when off it. Electronic collars do not satisfy the leash requirement. Letting a dog roam is a Class 1 misdemeanor. A second violation within 24 months carries a minimum $100 fine. A third jumps to at least $500. Any violation involving a dog previously declared vicious brings a minimum $500 fine plus at least five days in jail.⁸

The barking ordinance prohibits keeping a dog “in the habit of barking or howling” and disturbing the peace of anyone in the city. There’s no specific duration threshold; the standard is a pattern that disturbs neighbors. Civil sanctions run $150 to $2,500, and criminal convictions carry a minimum $150 fine.⁹

Backyard chickens are legal, with limits. On a half-acre lot or smaller, you can keep up to six head of poultry. Enclosures must sit at least 20 feet from neighboring property lines, cannot be in the front yard, and must prevent birds from wandering. Roosters and other male poultry are banned unless physically incapable of crowing. Going beyond six birds, or placing an enclosure closer than 20 feet, requires written consent from every adjoining property owner and occupant.¹⁰

Pool Barrier Requirements

Any pool, spa, or hot tub holding 24 inches or more of water must be enclosed by a barrier. The rules are strict:

Fence or wall at least five feet tall and non-climbable.
Gates that are self-closing and self-latching, opening outward and away from the pool.
Latch height at least four and a half feet above the ground, or designed to be inaccessible to small children from outside.
Any gap in the barrier under four inches wide.

If a house wall forms part of the enclosure, every door from the home into the pool area must also be self-closing and self-latching to the same standard as a gate.¹¹

Short-Term Rentals

Since November 2023, Phoenix has required a limited short-term rental permit for any property rented for fewer than 30 consecutive days. The permit costs $250, is non-refundable, and must be renewed annually. Applications run through the SHAPE PHX portal, and the city must issue or deny within seven days of receiving all required documents. Applicants need a Transaction Privilege Tax license from the Arizona Department of Revenue and must update their rental status with the Maricopa County Assessor’s Office. Owners also have to notify every single-family residential property adjacent to and diagonally across from the rental.¹²

Arizona state law sets the penalty ladder. A first verified violation can bring a fine up to $500 or one night’s rent, whichever is greater. A second reaches up to $1,000 or two nights’ rent. A third or later, up to $3,500 or three nights’ rent. Three verified violations within 12 months can trigger permit suspension for up to a year.¹³

Building Permits and Unpermitted Work

Most residential construction requires a building permit. That includes new structures over 200 square feet, room additions, wall removals, electrical rewiring, plumbing relocations, patio covers, porch enclosures, fences over three feet tall, and gas line work. Exempt projects include painting, replacing flooring, swapping kitchen cabinets or plumbing fixtures in existing locations, replacing an air conditioner of the same size and capacity in the same spot, and minor non-structural repairs like glass or trim replacement.¹⁴

Permits expire 24 months from the date of issue. If work is still active, the owner can request a one-year extension in writing before expiration; the fee is 50 percent of the current permit cost. An expired permit can be reinstated for up to one year if no changes have been made to the original plans and it’s been expired less than a year. Once a permit has been expired for a year or more, reinstatement is off the table and the owner has to apply for a new permit.¹⁵

If the city discovers work done without a permit, it issues a Notice of Violation, and the owner has 15 calendar days to submit a permit application. Failure to respond escalates to formal citations.¹⁶

How Enforcement Works and How to Report a Violation

Phoenix residents can report potential violations through the myPHX311 portal online or through the city’s mobile app. You select a category, provide the address, and get a case number to track the case.

For property maintenance complaints, the process usually begins with a pre-notification letter, not an immediate inspection. If the alleged violation isn’t a health or safety hazard and the property is occupied, the city mails the owner a letter and an inspector follows within ten days. When an inspector confirms a violation, the city issues a formal Notice of Violation with a correction deadline tied to severity:¹⁷

Minor violations: 15 days.
Significant-cost repairs or abatement cases: 35 days.
Graffiti: 10 days.
Health or safety hazards: 0 to 24 hours.
Illegal signs: 5 days.

Miss the deadline and the city escalates to formal citations or handles the cleanup itself and sends you the bill. For live noise complaints, call the non-emergency police line instead of using the portal; those require a real-time response that the inspection track isn’t built for.
