City of Phoenix Codes: Zoning, Permits, and Property Upkeep

The Phoenix City Code is the body of local ordinances the City Council has adopted to regulate how property is maintained, what gets built, how loud a neighborhood can be, and how animals, pools, and rentals are handled inside city limits. The rules carry teeth: inspectors can issue civil citations, the city can abate problems and bill the owner, and repeat violations become criminal misdemeanors with fines reaching $2,500 per offense.¹ Below are the provisions residents and property owners run into most, and what happens when they’re broken.

Property Upkeep Under Chapter 39

Chapter 39, the Neighborhood Preservation Ordinance, sets the baseline for how any residential or commercial property must look and function.² Vegetation drives most complaints. Lawn grass and weeds cannot exceed six inches. Properties must stay clear of dead trees, loose branches, dead palm fronds within ten feet of a structure or fence, and tumbleweeds.

The ordinance also prohibits accumulation of junk, litter, and debris on any lot, including discarded furniture and scrap metal. Perimeter fences and walls must stay structurally sound; leaning, collapsed, or missing sections count as violations.

Graffiti gets its own fast clock. Building exteriors must stay free of graffiti visible from the street or neighboring property, and after a notice of violation the owner has ten days to remove it. If nothing happens, the city sends a crew and bills the owner for the work.³

Penalties escalate within a rolling 36-month window:

First violation: civil sanction of at least $100, up to $2,500.
Second violation within 36 months: minimum rises to $250.
Third or subsequent violation within 36 months: minimum rises to $500.

Criminal convictions carry the same minimums. The absolute cap for any single offense is $2,500, before surcharges.¹

Noise, Construction Hours, and Outdoor Lighting

Chapter 23 handles noise without setting a single decibel number. Instead, it lists categories of disturbing sound and gives special weight to the hours between 11:00 p.m. and 7:00 a.m., when loud music, shouting, and similar activity are specifically flagged as disturbing to nearby homes, hotels, or hospitals.⁴ Daytime noise is not automatically legal; any sound that disturbs the comfort or repose of others can trigger enforcement.

Construction Hours

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

Outdoor Lighting

Light trespass falls under the same chapter. High-intensity outdoor fixtures must be fully shielded so light projects downward rather than spilling onto neighboring property. The rule applies to high-pressure sodium, metal halide, fluorescent, quartz, and incandescent bulbs over 150 watts. Fixtures with an automatic shutoff that keeps them dark between 11:00 p.m. and sunrise are exempt from the shielding requirement.⁵

Zoning, Setbacks, and What You Can Build

The Phoenix Zoning Ordinance controls what gets built, where it sits on the lot, and how tall it can be. Residential setbacks define the minimum distance between structures and property lines. Accessory structures like sheds, workshops, and detached garages are capped at 15 feet when placed in a required rear or side yard; when located outside required yards, they can match the height allowed for the main house.⁶ Exceeding these limits without an approved variance triggers a modification order.

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 accessory dwelling unit on any single-family lot. Under the Phoenix ordinance, a detached ADU on a lot up to 10,000 square feet cannot exceed 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 the ADU don’t count toward that square footage. Height in required yards caps at 15 feet. ADUs cannot be used as short-term rentals.⁶

Home-Based Businesses

Phoenix allows home occupations, but the rules are stricter than many people expect. Only family members living in the home can work in the business. No signage, displays, or stored materials can be visible from the street. The business cannot occupy more than 25 percent of the total area under roof. Operating hours must stay within 7:00 a.m. to 10:00 p.m. Odor, dust, noise, vibration, smoke, heat, and glare cannot cross property lines. A home occupation that generates outside traffic, operates from an accessory building, or involves outdoor use requires a use permit.⁷

Animal Rules

Chapter 8 governs pet ownership, and the leash law produces most of the citations. Dogs must be confined on the owner’s property or controlled on a leash no longer than six feet off-property. Electronic collars do not satisfy the leash requirement. Letting a dog run at large is a Class 1 misdemeanor. A second violation within 24 months carries a minimum $100 fine, a third jumps to at least $500, and 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” that disturbs the peace of any person in the city. The code does not fix a duration threshold; the standard is a disturbing pattern. Civil sanctions range from $150 to $2,500, and criminal convictions carry a minimum $150 fine.⁹

Backyard Chickens

Poultry is legal within limits. On a half-acre lot or smaller, you can keep up to six head. Exceeding that cap requires written permission from every adjoining property owner and occupant. Enclosures must sit at least 20 feet from neighboring property lines, cannot occupy the front yard, and must prevent birds from wandering onto other properties. Male poultry are banned unless physically incapable of crowing.¹⁰

Pool Barrier Requirements

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

Fence or wall at least five feet high and non-climbable.
Gates 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 the outside.
Any gap in the barrier less than four inches wide.

If the house wall serves as part of the enclosure, every door from the home into the pool area must 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 (non-refundable) and renews annually. Applications go 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 must notify all single-family residential properties adjacent to and diagonally across the street from the rental.¹²

Arizona state law sets the penalty framework. A first verified violation can bring a fine up to $500 or one night’s rent (whichever is greater), a second up to $1,000 or two nights’ rent, and a third or subsequent 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

Most residential construction in Phoenix requires a permit, including 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

Expiration and Reinstatement

A building permit expires 24 months after it was issued. If work is still underway, 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 the permit has been expired less than a year. Permits expired a year or more cannot be reinstated, and the owner must start over with a new application.¹⁵

Work Done Without a Permit

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

Reporting Violations and Correction Timelines

Residents report potential violations through the myPHX311 portal online or via the city’s mobile app. Users select a category, provide the address, and receive a case number for tracking. For noise complaints that need a real-time response, call the non-emergency police line instead, since the inspection process is not built for immediate issues.

For property maintenance complaints that are not health or safety hazards, the city often starts with a pre-notification letter to the owner before an inspection follows within ten days. Once an inspector confirms a violation, the Notice of Violation sets a correction deadline keyed 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.

If the deadline passes without correction, the city issues formal citations or performs the cleanup itself and bills the owner for the cost.
