The District also performs floodplain management services for several cities within Maricopa County. -
Air Quality issues dust control, asbestos, open burn, and stationary source permits.
Dust control permits are required for any project disturbing more than 0.1 acres (about 4,356 square feet). -

Maricopa County Zoning Information
Before applying for a permit in an unincorporated area, you need to confirm the property is zoned for the intended use. Maricopa County zoning is governed by the Maricopa County Zoning Ordinance (MCZO), with a modernized version that took effect January 9, 2026 after a comprehensive rewrite by the Board of Supervisors.
Common zoning districts include:
Rural-43, Rural-70, Rural-190: Rural zoning districts with minimum lot sizes ranging from 43,000 square feet to roughly 4.4 acres.
R1-43, R1-35, R1-18, R1-10, R1-8, R1-6: Single-family residential districts at varying densities.
R-2, R-3, R-4, R-5: Multi-family residential districts ranging from low to high density, including mobile home park provisions in R-5.
C-1, C-2, C-3: Commercial districts from neighborhood-scale to general commercial uses.
IND-1, IND-2, IND-3: Industrial districts for light, heavy, and recycling/heavy industrial uses.
Overlay Zones: Include the Military Airport Overlay around Luke Air Force Base, Dark Sky Lighting standards, and floodplain overlays.
The 2026 zoning update introduced several notable changes, including provisions for multiple accessory dwelling units per single-family lot, short-term rental standards, removal of the "plan of development" requirement for smaller multi-family projects, and expanded definitions for emerging technologies like Battery Energy Storage Systems and data centers.
Zoning information for a specific property can be researched through the Maricopa County Zoning Map.
Maricopa County Building Code
Building codes in Arizona are adopted at the local jurisdiction level. For unincorporated areas of Maricopa County, the Board of Supervisors adopts the International Code Council's model codes along with the Maricopa County Local Additions and Addenda (MCLAA).
Maricopa County currently enforces the 2018 International Building Code along with amendments approved by the Board of Supervisors in August 2022. The adopted code suite also includes the 2018 International Residential Code, 2018 International Fire Code, 2018 International Plumbing, Mechanical, and Fuel Gas Codes, the 2017 National Electrical Code, and the 2018 International Energy Conservation Code. Local amendments address Maricopa County-specific conditions including extreme heat considerations, energy efficiency requirements, floodplain regulations, and dark sky lighting standards.
Code year alignment varies across Maricopa County's incorporated cities. Phoenix, Scottsdale, and several other municipalities have adopted newer code cycles than the county, which means projects that straddle jurisdictional lines or move between city and county review may need to address different requirements.
Construction projects in Maricopa County must also comply with statewide code requirements adopted by the State of Arizona.
Maricopa County Permit Approval Timeframe
Maricopa County offers several review tracks depending on project complexity, all administered through the Permit Center launched in June 2024. The four primary tracks are Standard Review, Fast Track, Permit by Inspector, and Annual Facilities Permit.
Standard Review applies to most residential and commercial projects, with initial plan review typically completed within 5 to 30 business days depending on project type and department workload. MCDOT right-of-way reviews target 20 business days for turnaround.
Fast Track offers an expedited review for simple projects with no dominant zoning, environmental, drainage, or floodplain concerns. Eligible projects can be processed the same day in person or within two days online after plans are accepted.
Permit by Inspector allows certain residential alterations and repairs to be reviewed in the field by the inspector rather than going through formal plan review. This is useful for smaller projects that meet the program's eligibility criteria.
Annual Facilities Permit is designed for qualified commercial facilities, allowing routine work on existing buildings to be authorized under a single annual permit rather than requiring individual permits for each project.
Once issued, Maricopa County permits require construction activity to begin within 180 days, with continued inspections required to keep the permit active. One free 180-day extension is available if requested within 180 days of expiration.
Step-by-Step: How to Get a Permit in Maricopa County
1. Confirm jurisdiction: Verify your property is in unincorporated Maricopa County rather than within an incorporated city or town. Projects inside city limits go through that municipality's permitting department.
2. Determine which county departments are involved: Most projects involve Planning and Development at a minimum, but septic, food, air quality, floodplain, or right-of-way work may also require permits from Environmental Services, Air Quality, Flood Control District, or MCDOT.
3. Identify your review track: Standard review applies to most projects. Fast Track is available for simple work with no major zoning, drainage, or floodplain concerns. Permit by Inspector and Annual Facilities Permit may be available depending on the project type and the facility.
4. Set up your Permit Center account: All applications run through the Permit Center launched in June 2024. Personal and company accounts have different registration paths, so set up your account before you're ready to submit.
5. Confirm zoning and overlay requirements: Check the property's zoning district, applicable overlay zones (Military Airport, Dark Sky, floodplain), and any zoning interpretations that may affect the project. A Pre-Application meeting is recommended for complex commercial or non-residential projects.
6. Address environmental requirements: Properties without sewer service need an approved septic system through Environmental Services. Dust control permits through Air Quality are required for any disturbance over 0.1 acres.
7. Prepare your plans: Construction documents must meet the 2018 International Building Code as amended by the Maricopa County Local Additions and Addenda. Plans should be uploaded as PDFs that meet the county's document guidelines.
8. Submit your application: Upload plans and supporting documents through Permit Center. Pay any upfront fees required to begin review.
9. Plan review: Reviewers from Planning and Development, Flood Control, MCDOT, and other applicable departments review the application based on permit type. Comments are issued through Permit Center.
10. Respond to corrections: Upload an updated full set of documents through Permit Center to start a new review round. Each correction cycle adds time to the overall timeline.
11. Pay final fees and pull the permit: Once review is complete, final permit fees are applied and the permit can be issued. Print and post the permit on site before construction begins.
12. Schedule inspections: Inspections are scheduled through Permit Center. The county requires regular inspection activity to keep the permit active.

How Much Do Permits Cost in Maricopa County?
Maricopa County calculates permit fees based on project valuation, square footage, and inspection requirements, with the full fee structure established by the Board of Supervisors and incorporated into Ordinance P-36. Initial or upfront fees are required when a project is accepted for review, with final fees applied before the permit is issued.
Fees in Maricopa County are distributed across the five permitting departments. Planning and Development fees cover building plan review and inspections, while Environmental Services, Flood Control District, Air Quality, and MCDOT each have their own separate fee schedules for their respective permit types.
General ranges to budget for:
Simple residential permits (water heater, HVAC swap, minor electrical): $100 to $500
Mid-size residential projects (room addition, remodel): $500 to $3,000
Commercial tenant improvements: $2,000 to $15,000+
New commercial construction: $10,000 and up
Renewal and extension fees apply if permits expire. Applicants requesting an extension within 90 days of expiration pay a renewal fee equal to 20 percent of the original permit fee. Renewals requested more than 90 days after expiration are charged the full new application fee. Initial fees are non-refundable, and refund requests for unused balances typically take four to six weeks to process.
