County business license guide
Accuracy checked and last updated: August 1, 2026 · Next review: December 1, 2026
A Maricopa County business may deal with a city or town, the county, Arizona agencies, and federal agencies. The right list depends on your exact address and what the business does. This guide shows where to start before you open, sign a lease, buy equipment, sell food, hire workers, or take bookings.
Bottom line
Maricopa County does not issue or require one general business license for businesses in unincorporated county areas. That does not mean you are cleared to operate. You may still need county zoning or building approval, a food permit, an Arizona Transaction Privilege Tax license, a city or town license, or an industry license.
If the address is inside Phoenix, Mesa, Chandler, Glendale, Scottsdale, Gilbert, Tempe, Surprise, or another city or town, start with that municipality. A mailing address that says “Phoenix” does not always prove that the property is inside Phoenix city limits.
Quick start: check these five things first
- Confirm the legal jurisdiction. Write down the physical address and parcel number. Ask whether it is inside a city or town or in unincorporated Maricopa County.
- Describe the business in one clear sentence. Include what you sell, where customers meet you, whether food or alcohol is involved, and whether you will use a home, vehicle, booth, office, warehouse, or storefront.
- Check the local layer. Use the city or town licensing page if the address is incorporated. Use county planning and permit offices if it is unincorporated.
- Check Arizona TPT and state licensing. TPT may apply to retail, restaurants, rentals, contracting, lodging, and other taxable business classes. Regulated work may need a separate state license.
- Check the site before spending money. Confirm zoning, occupancy, building, fire, signs, parking, home-business limits, and health rules before signing a lease or buying major equipment.
Which government layer handles what?
Business owners often use the words “business license” for several different filings. In Maricopa County, those filings can come from different offices. One approval does not replace the others.
| Layer | What it may control | First place to check |
|---|---|---|
| Federal | EIN, federal employer taxes, and permits for federally regulated activities | IRS, SBA, and the federal agency for the activity |
| Arizona | LLC or corporation filing, TPT, trade name, employer accounts, professional and industry licenses | Arizona Business One Stop and the agency that regulates the work |
| Maricopa County | Unincorporated-area zoning and building, food permits, mobile food, rental registration, and other activity-specific permits | County Licenses & Permits, Permit Center, Planning and Development, Environmental Services, or the Assessor |
| City or town | Local business license or registration, zoning, occupancy, signs, fire, vending, short-term rental, and regulated activities | The municipality where the physical address or job site is located |
| Private party | Lease, HOA, marketplace, delivery app, payment processor, insurer, or event organizer rules | Your contract or platform account |
For a plain-English comparison, read business license vs. LLC vs. DBA vs. seller’s permit. Arizona calls its main sales-related tax license the Transaction Privilege Tax license, or TPT. It is not a general county license and it does not approve zoning.
Maricopa County business license and permit rules
No general county business license
The county’s official Licenses & Permits page says Maricopa County does not issue or require a general business license for unincorporated areas. It tells businesses inside an incorporated city or town to check with that municipality.
This county rule is easy to misunderstand. “No general county license” does not mean “no county permits.” The county may still regulate the property, the building, food handling, a mobile food unit, a pool, air emissions, a road connection, or another specific activity.
Unincorporated property, zoning, and construction
If the site is outside city or town limits, start with Maricopa County Planning and Development. The department handles land-use planning, building permit review, inspections, and code compliance in unincorporated Maricopa County.
Many applications go through the county’s Permit Center. The Permit Center is used by Environmental Services, Planning and Development, Transportation, and Flood Control. Ask which department owns your application before uploading plans or paying a fee.
Check the address before you file
Do not rely only on the city name in a postal address. A property can use a Phoenix, Mesa, or Scottsdale mailing name while being outside that city’s legal boundary. Give the agency the street address and parcel number and ask, “Which government has zoning and licensing authority over this property?”
Food establishments and mobile food units
Restaurants, bakeries, caterers, grocery operations, food-prep spaces, temporary food booths, and many other food businesses should check Maricopa County Food & Restaurants. A new or remodeled fixed food business may need plan review before construction and an inspection before opening.
Food trucks, trailers, carts, and some event vendors should use the county’s Mobile Food Establishments page. A county food permit controls food safety. It does not give permission to park, vend, use private property, or operate at any location you choose. The city, property owner, fire department, and event organizer may have separate rules. The BLG food truck license and permit guide explains the usual permit stack.
Residential rental property
Arizona law requires residential rental property information to be registered with the county assessor. Maricopa County owners can start with the Assessor’s rental registration guidance. This filing is separate from a city short-term rental license, Arizona transient lodging tax duties, insurance, and platform rules.
Long-term residential rental TPT changed on January 1, 2025. Do not use an old blog or old tax account as your only guide. Ask ADOR and the city whether your activity is long-term residential rental, transient lodging, commercial lease, property management, or another taxable class.
County phone script
What to say
“My business will operate at [full address and parcel number]. I will [plain description of activity]. Is this property in unincorporated Maricopa County? Does the county require zoning approval, a building permit, a food or health permit, or another activity-specific permit before I open?”
The county lists 602-506-3766 for questions about the Maricopa County application process. Ask to be routed to the department that handles your exact activity.
Phoenix metro city and town rules
Most people in Maricopa County operate inside a city or town. Local rules are not uniform. Some places use a general business license. Some use a business registration. Phoenix does not issue one general city business license, but it licenses certain regulated activities and has separate tax, zoning, building, sign, vending, and fire processes.
| Municipality | Main local starting point | What to know |
|---|---|---|
| Phoenix | Phoenix License, Permitting & Certification Services | Phoenix says it does not issue a general business license. Check regulated licenses, TPT, zoning, building, fire, signs, vending, and occupancy. See the Phoenix business license guide. |
| Mesa | Mesa Licensing | Mesa lists a General Business License for most Mesa businesses and separate specialty licenses. See the Mesa business license guide. |
| Chandler | Chandler Business Registration | Chandler requires a business registration for each physical business location in city limits, unless an exception applies. See the Chandler business license guide. |
| Glendale | Glendale business license system | Check the city license for a permanent physical location and ask whether a specialty license, TPT, zoning, fire, or sign approval also applies. See the Glendale business license guide. |
| Scottsdale | Scottsdale Business & Regulatory Licenses | Check the Business Registration License and any special license for mobile food, short-term rental, alarms, or another regulated activity. See the Scottsdale business license guide. |
| Gilbert | Gilbert Business Registration and Licensing | Gilbert says commercial and home-based businesses located in the town need a business license. The local license and Arizona TPT are different. See the Gilbert business license guide. |
| Tempe | Tempe General Business License | Tempe’s General Business License took effect in 2025 and covers permanent locations, many home businesses, TPT businesses, and other listed activities. Check annual renewal instructions. |
| Surprise | Surprise Business Licensing | Surprise requires a city business license for people carrying on business within city limits. Home and commercial applicants may need zoning review and supporting forms. |
This table is a starting point, not a full list of Maricopa County municipalities. Peoria, Avondale, Goodyear, Buckeye, Tolleson, El Mirage, Fountain Hills, Queen Creek, Wickenburg, Youngtown, Paradise Valley, Cave Creek, Carefree, Gila Bend, and other local governments may have their own process. Check the municipality that controls the address or job site.
Ask for the exact name of the local filing
Do not ask only, “Do I need a business license?” Say what you do and ask whether you need a general license, business registration, TPT location, home occupation approval, zoning clearance, certificate of occupancy, specialty license, sign permit, fire permit, or short-term rental license.
Arizona state registrations, taxes, and industry licenses
Arizona does not issue one blanket state business license that covers every business. The state layer may include entity formation, a trade name, TPT, employer accounts, or a license for a regulated trade or industry. The BLG Arizona business license guide gives a wider state overview.
LLC or corporation filing
Use Arizona Business One Stop to build a state checklist and reach state filing tools. LLCs and corporations are formed or registered through the Arizona Corporation Commission Corporations Division. The ACC states that it does not issue city business or occupational licenses.
An LLC is a legal structure. It does not prove that your address is zoned for the activity, that you hold TPT, or that you have county food or city licensing approval.
Trade name
If you use a public business name that differs from your legal personal name or entity name, check the Arizona Secretary of State’s Trade Names and Trademarks program. A trade name is a name filing. It is not an LLC, a city license, a trademark for the whole United States, or proof that another business cannot challenge the name.
Arizona Transaction Privilege Tax
Arizona’s TPT is a tax on the privilege of doing business in taxable classes. It is often called a sales tax license, but the legal structure is different from a typical consumer sales tax. Start with ADOR’s TPT License page and apply, file, pay, or renew through AZTaxes.gov.
A business may need to list each Arizona location or city where it has a taxable base or operation. Business codes, region codes, and rates can change, so use ADOR’s current TPT rate table instead of copying a rate from an old article. ADOR requires TPT licenses to be renewed annually. Check the current renewal notice and close locations that are no longer active.
Contractors, liquor, and other regulated work
Construction and many trade activities may require an Arizona contractor license. Check the Arizona Registrar of Contractors before advertising, bidding, or taking work that may be regulated. A license does not replace the building permit for a job site.
Businesses that manufacture, sell, or serve alcohol must use the Arizona Department of Liquor Licenses and Control. Liquor licensing includes state review and a local city, town, or county recommendation. Do not sign a lease based only on the hope that a liquor license will be approved.
Child care, health care, behavioral health, cosmetology, real estate, transportation, cannabis, security, professional services, and other fields can have their own state board or agency. Search by the exact activity, not just the word “business.”
Federal steps
EIN
An Employer Identification Number is a federal tax ID, not a business license. Get it free from the IRS EIN page. Many businesses need an EIN because they have employees, use a corporation or partnership, open certain accounts, or file certain federal taxes.
Federal permits
The SBA license and permit guide explains that requirements depend on activity, location, and government rules. Federal permits may apply to alcohol, aviation, firearms, broadcasting, transportation, wildlife, agriculture, or another federally regulated field.
Beneficial ownership reporting
Do not rely on old Corporate Transparency Act checklists. FinCEN’s current beneficial ownership information page says entities created in the United States are exempt from BOI reporting under the March 2025 rule. Certain foreign entities registered to do business in the United States may still have duties. Check FinCEN again before acting because federal rules can change.
Common Maricopa County business situations
Home-based consultant in Phoenix
Phoenix has no general city business license, but the owner should still check home occupation and zoning rules, TPT if the service falls in a taxable class, and any professional license. An LLC and EIN do not replace these checks.
Online seller based in Chandler
The physical business base is in Chandler even when customers are elsewhere. Check Chandler Business Registration, home-business limits, Arizona TPT, and inventory or delivery issues. A marketplace may collect tax on some sales, but its platform rules do not replace government filings. See online business license basics.
Restaurant opening in Mesa
Check the Mesa General Business License, zoning, certificate of occupancy, fire approval, signs, building work, Arizona TPT, and Maricopa County food plan review and permit steps. Get agency feedback before finalizing the lease or kitchen plan.
Food truck working across the metro area
A county mobile food permit does not create a countywide right to park and sell. Check each city’s vendor, zoning, fire, event, and private-property rules. Add the correct TPT locations and keep permits available in the unit.
Contractor with jobs in several cities
Check the Arizona contractor license, TPT classification, the business registration rule for the home city, local contractor or business licenses where required, and a permit for each regulated job. Do not treat one city’s license as a metro-wide license.
Short-term rental in Scottsdale
Check the Scottsdale short-term rental license, Maricopa County Assessor rental registration, Arizona transient lodging tax rules, neighbor notice, liability insurance, pool rules, and platform requirements. Long-term residential rental tax changes do not automatically apply to short stays.
Common mistakes to avoid
- Applying to the wrong government. Confirm city limits or unincorporated status before filing.
- Stopping after forming an LLC. Entity formation does not replace local licenses, zoning, TPT, health permits, or professional licensing.
- Calling every filing a business license. Ask for the exact permit, registration, tax account, or approval.
- Signing a lease before site review. The use may need zoning, occupancy, parking, fire, grease control, accessibility, or building work.
- Assuming a food permit covers vending locations. County food approval and city location permission are separate.
- Using the wrong TPT location or business code. A wrong code can affect filing, rates, and city reporting.
- Forgetting renewals and account closures. Track city, TPT, health, rental, professional, and specialty-license dates separately.
- Trusting an old fee or deadline. Open the official page on the day you file and save the fee schedule or instructions used.
Simple document checklist
Not every agency asks for every item, but gathering these records can reduce delays.
- Physical address, parcel number, and lease or owner permission
- Plain description of products, services, equipment, customer visits, deliveries, and hours
- Legal owner names and contact information
- Entity documents, if you formed an LLC or corporation
- EIN, when required or requested
- Trade name information, if used
- Arizona TPT number and location codes, when applicable
- Floor plan, site plan, menu, equipment list, vehicle details, or sign plan when relevant
- Professional, contractor, liquor, health, or other state license information
- Insurance certificates when required by a city, landlord, platform, or contract
- Copies of approvals, receipts, inspection reports, and renewal notices

No. Maricopa County says it does not issue or require a general business license for unincorporated county areas. You may still need county zoning, building, food, health, rental, air quality, road, or other activity-specific permits.
Do I need a city license if I have an Arizona TPT license?
Maybe. A TPT license is a state-administered tax license. A city or town may also require a general business license, business registration, specialty license, zoning approval, certificate of occupancy, fire permit, or sign permit.
Does Phoenix have a general business license?
No. Phoenix says it does not issue one general business license. Certain activities need a city license or approval, and businesses may also need Phoenix TPT, zoning, building, fire, vending, sign, or occupancy steps.
How do I know whether my address is in a city or unincorporated Maricopa County?
Use the physical address and parcel number, then ask the city or Maricopa County Planning and Development which government has zoning authority. Do not rely only on the postal city name.
Do home-based businesses need local approval?
Often, yes. The city or county may limit customer visits, employees, deliveries, outdoor storage, signs, noise, vehicles, or equipment. A lease or HOA may add private restrictions, but private approval does not replace government rules.

No. An LLC is a legal entity filed with the Arizona Corporation Commission. It does not replace TPT, a city license, county permit, zoning approval, professional license, health permit, or federal permit.
What does a food truck need in Maricopa County?
A food truck may need a Maricopa County mobile food permit, plan or equipment review, fire approval, Arizona TPT, city vending or business licensing, permission for each site, commissary arrangements, and event approval. The exact list depends on the unit, menu, and locations.
Do I need to renew an Arizona TPT license?
Yes. ADOR requires TPT licenses to be renewed annually. Use the current ADOR renewal notice for the due date, fees, late rules, and instructions, and close locations that are no longer operating.
