Phoenix permits, summer work hours and city rules for contractors

Phoenix is where the state does most of the licensing and the city does the permitting. That makes the city page shorter than a place like Chicago, but it has some rules that surprise newcomers: the summer work hours, a license for painting address numbers on curbs, and a stormwater code that reaches wash water. The details below come from the City of Phoenix, the Arizona Legislature and the National Weather Service, as listed in October 2026. It is general information and not legal advice. Some city handouts carry older revision dates, which are noted where they matter.

Arizona licenses, Phoenix permits

Arizona runs contractor licensing through the Registrar of Contractors, including the handyman exemption for jobs under $1,000 and the requirement that handyman ads say "not a licensed contractor". Our Arizona contractor licenses guide and Arizona page cover that, with the state's transaction privilege tax and workers' compensation rules. Phoenix adds permits, a few city licenses, noise and stormwater codes. The city's License Services brochure says the City of Phoenix does not have or issue a general business license, and that only certain types of activities are regulated and require licensing.

What the City Clerk licenses, and what it does not

The City Clerk's License Services section lists the activities it licenses. They include street and mobile vending, secondhand and scrap metal dealers, auction houses, massage establishments, liquor and several others. For tax, the brochure sends people to the Arizona Department of Revenue. Phoenix's tax page says a business with transaction privilege tax liability needs a city tax license, reported through the state system. The page lists the city rate at 2.8 percent on most activities, up 0.5 percentage points under Ordinance G-7369 effective July 1, 2025, and says the rate varies by business activity. The city's January 2025 public notice shows 2.3 percent as the rate before that increase, so a 2.3 figure on an older page or in an old guide is out of date. Confirm the rate for your activity on the city's current rate chart. The city's license fee page lists a $50 non-refundable first-year license fee due within 30 days of your start date, with a 50 percent late fee ($25) added if it is late. How a contractor's work is classified for this tax is a state question, covered on the Arizona page.

Painting house numbers on curbs takes a city license

If part of your business is painting address numbers on curbs and driveway aprons, Phoenix licenses it under City Code Chapter 31, Article X. The city's fee sheet, revision 7-12, lists a $30 nonrefundable application fee and a $30 annual license fee. The rules say:

• You need the owner-occupant's permission, and you must show your current license before painting.
• Business activity is limited to 8 a.m. to 8 p.m. daily.
• The paint must be reflective and in a contrasting color. Numbers go within the driveway or start within three feet of it and must be at least three inches high.
• You are responsible for all cleanup, and the license expires at the end of the calendar year and cannot be transferred.

The City Clerk's page lists a state transaction privilege tax license from the Department of Revenue, and says you may need a building or use permit from Planning and Development. Applications are by appointment at 602-262-4638.

The state license number is the gate for permits

The Planning and Development Department's permit issuance sheet, revision 1/19, says state and city law require construction to be performed by state-licensed contractors, and that applicants must give a state contractor's license number under A.R.S. section 32-1169. It restates the state rule that work by anyone other than the property owner needs a licensed contractor when a permit is required or the cost is more than $1,000. Out-of-state contractors on permits where construction value is above $50,000 need an Arizona Department of Revenue surety bond or a bond exemption certificate. Right-of-way permits add a certificate of liability insurance and a construction bond.

The sheet applies the licensed-contractor rule to work done by someone other than the property owner. It also says owners and developers who sell or rent a property within one year of construction must use licensed general contractors for all new construction. The city can ask for a written statement from the Registrar of Contractors to verify an exemption.

The residential projects page lists what does and does not need a permit:

The page points to the city's Work Exempt from Permit document for the complete list.

Summer construction hours follow a 2025 state law

Phoenix's after-hours construction noise page says a new state law took effect on May 13, 2025 and sets legal summer construction hours for every Arizona city and town. From May 1 to October 15, legal hours are Monday through Friday 5 a.m. to 7 p.m. and Saturday 7 a.m. to 7 p.m. Concrete may be poured up to one hour before the hours start, and the page says that for work with a valid permit, summer hours cannot be restricted under the law. The page does not state hours for the rest of the year, so confirm those with Planning and Development. Report after-hours construction noise at 602-262-7456. Other noise complaints go to the police non-emergency line, 602-262-6151.

Stormwater: what can go down the drain

The Water Services Department says only stormwater belongs in the storm drain. It lists allowed non-stormwater discharges, as long as they are not a source of significant pollutants, including individual residential car washing, street wash water, lawn watering and dechlorinated pool discharges. Its FAQ cites City Code Chapter 32C and says businesses with a potential to pollute, and construction projects that disturb an acre or more, must have a stormwater management plan. The pages do not name mobile pressure washing, so a commercial wash crew should call Water Services and not assume street wash water covers a customer's driveway job. The stormwater hotline is 602-256-3190. Our pressure washing start-up guide covers the business side.

Arizona 811 and the white line

Under A.R.S. section 40-360.22, an underground facility operator must mark its lines within two working days of the excavator's inquiry, and a landlord in an apartment community or mobile home park has ten working days. Digging cannot start before marking is complete or the excavator is told none is needed. Before you submit a request, the statute requires you to mark the area to be excavated with white lining. The white-lining step does not apply to excavations a person performs on single-family residential property that the person owns or occupies. The marking deadlines above are the operators' duty, so confirm with Arizona 811 how a notice request works for your job.

The desert calendar

NWS Phoenix reports a 1991 to 2020 normal of 7.22 inches of precipitation a year. In 2025 the city had 37 days at or above 110 degrees and 8.31 inches of rain.

What this means for your website and phones

Put your Registrar of Contractors license number, or "not a licensed contractor" if you rely on the handyman exemption, in your website footer and on your trucks. When your crew starts at 5 a.m. under the summer hours, an AI receptionist can answer the calls that come in while everyone is on a roof. Arizona exempts recording by a party to the call under A.R.S. 13-3012, covered in the call recording guide. Rules change, so verify before you act.
