Permitting Authorities in Pinal County

Pinal County permitting runs through several departments housed primarily under Community Development and Public Works, along with separate environmental and flood control authorities. The right mix of agencies depends on project type and location.

Building Safety provides inspection, plan review, and investigative services for all unincorporated areas of the county.

The division also serves cities that have entered into intergovernmental agreements (IGAs) with the county for building code services.

Applications are submitted through the Pinal County Online Permitting Citizen Access Portal.
The Planning Division handles zoning, site plan review, subdivisions, Concept Reviews, and special permits including Temporary Use Permits, Special Events Permits, and Special Density Permits.
Environmental Health handles permits for septic systems, public pools, food establishments, hotels, and other public health facilities.

Environmental Health permits operate independently from building permits and often require parallel applications.
The Flood Control District is the Floodplain Administrator for all unincorporated areas and many cities within the county. Floodplain Use Permits are required for any development in a Special Flood Hazard Area and must be applied for separately from building permits.
Public Works handles right-of-way permits, transportation review, stormwater compliance, and grading. Projects affecting county-maintained roads or disturbing more than one acre may require additional permits through this department.
Fire code review for projects outside city limits is handled by local rural fire districts, including Superstition Fire and Medical, Eloy Fire District, Mountain Vista Fire District, and others depending on project location. The Arizona Department of Environmental Quality handles state-level environmental compliance.

Pinal County Zoning Information

Before applying for a permit in an unincorporated area, you need to confirm the property is zoned for the intended use. Pinal County zoning is governed by the Pinal County Development Services Code, Title 2 (Zoning), which establishes the county's zoning districts, allowed uses, and development standards.

Common zoning districts include:

SR Suburban Ranch, SR-1, SH Suburban Homestead, CAR Commercial Agriculture Ranch: Larger-lot residential and agricultural districts that reflect the county's rural character.

GR, GR-5, GR-10 General Rural: Rural zoning districts at varying lot sizes for low-density residential and agricultural uses.

RU-10, RU-5, RU-3.3, RU-2, RU-1.25 Rural: Rural residential districts with minimum lot sizes ranging from 1.25 to 10 acres.

CB-1, CB-2 Business; C-1, C-2, C-3 Commercial; O-1, O-2 Office: Commercial and office districts ranging from neighborhood-scale to general business uses.

CI-B, CI-1, CI-2, I-1, I-2, I-3 Industrial: Industrial districts for light industrial, warehouse, and manufacturing uses.

MH Manufactured Home, MHP Manufactured Home Park, PM/RVP Park Model/RV Park: Manufactured housing and recreational vehicle district types.

MP-CMP Multi-Purpose Community Master Plan, PAD Planned Area Development: Districts for large-scale planned communities and master-planned development.

A major zoning code modernization is currently underway. The county is updating Title 2 to address dark sky overlay standards, microschools, aquifer protection, water conservation, breweries, mobile vendors, animal husbandry, and landscaping, along with new requirements for properties in high noise or accident potential zones. The changes will not be retroactive to existing land uses.

Zoning information for a specific property can be researched through the Pinal County Interactive Zoning Map.

Pinal County Building Code

Building codes in Arizona are adopted at the local jurisdiction level. For unincorporated areas of Pinal County, the Board of Supervisors adopts the International Code Council's model codes along with county-specific amendments under the Pinal County Development Services Code.

Pinal County currently enforces the 2018 International Building Code along with amendments approved by the Board of Supervisors. The adopted code suite also includes the 2018 International Residential Code, 2018 International Fire Code, 2018 International Plumbing, Mechanical, and Fuel Gas Codes, and the 2017 National Electrical Code. Local amendments address Pinal County-specific conditions including floodplain regulations, hillside development, wildland fire considerations, and the unique requirements of master-planned communities.

Code alignment varies across Pinal County's incorporated cities and towns. Some 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 Pinal County must also comply with statewide code requirements adopted by the State of Arizona.

Pinal County Permit Approval Timeframe

Permit timelines in Pinal County vary by project type and the departments involved in review. Applications are submitted through the Pinal County Citizen Access Portal, where Building Safety, Planning, Flood Control District, Public Works, and Environmental Health review their respective scopes in parallel.

Standard residential projects typically clear initial plan review within a few weeks, while commercial and complex projects can take longer due to multi-department coordination. Building Safety publishes target review times for each permit type, with timelines depending on submittal completeness and current department workload.

Once issued, permits remain valid as long as construction progresses through periodic inspections. The Building Official may extend the time for action by an applicant for a period not exceeding 180 days upon written request, similar to the standard practice across Arizona jurisdictions.

For floodplain projects, the Flood Control District typically issues Floodplain Use Permits within 2 to 5 weeks for single-family residential projects and longer for complex commercial work. Floodplain Use Permits are issued separately from building permits and often run on parallel timelines.

Inspections are scheduled through the automated inspection line at 520-866-6299. Same-day inspections are available if called in by 6 a.m., and inspections can be scheduled up to three days in advance.

Step-by-Step: How to Get a Permit in Pinal County

1. Confirm jurisdiction: Verify your property is in unincorporated Pinal County rather than within an incorporated city or town. Projects inside city limits like Casa Grande, Maricopa, Apache Junction, Florence

2. Determine your permit type: Pinal County issues building permits, mechanical/plumbing/electrical permits, grading permits, manufactured home permits, solar permits, special use permits, and right-of-way permits, among others.

3. Identify which departments are involved: Most projects involve Building Safety. Septic, food, or pool projects also require Environmental Health permits. Floodplain projects require a separate Floodplain Use Permit from the Flood Control District. Right-of-way and grading work go through Public Works.

4. Check zoning and confirm access: Verify the property zoning supports the intended use through the Pinal County Interactive Zoning Map. For all residential building permits, Pinal County requires applicants to affirm that legal and physical access to the property exists.

5. Set up your Citizen Access Portal account: All applications are submitted through Pinal County's online portal. The applicant, property owner, or contractor needs an account tied to the project email.

6. Prepare your plans: Construction documents must meet the 2018 International Building Code with Pinal County amendments. Plans must be uploaded as PDFs and include an architectural site plan uploaded separately from construction drawings. RES Check reports are required for energy compliance.

7. Submit your application: Upload plans, supporting documents, and any required affirmations through the Citizen Access Portal. All contractors must hold an active Arizona ROC license in the appropriate specialty classification.

8. Review and corrections: Pinal County departments review the application and issue corrections through the portal. All communication regarding the permit comes via email from a no-reply address, so monitor spam folders.

9. Pay fees and pull the permit: Once review is complete, final permit fees are applied. Payment can be made by credit card or electronic check through the portal. Permits and approved plans become available for download from your account.

10. Schedule inspections: Inspections are scheduled through the automated inspection line at 520-866-6299, with same-day inspections available if requested by 6 a.m. and scheduling up to three days in advance.

11. Floodplain coordination: If applicable, the Flood Control District issues Floodplain Use Permits separately from building permits. Floodplain documentation, including elevation certificates and engineered foundation plans, must be submitted in parallel.

12. Permit close-out: Final inspection closes the permit. The Building Official may grant up to 180-day extensions in writing if the applicant needs additional time.

Speeding Up the Permit Process in Pinal County

Pinal County requires residential applicants to affirm legal and physical access to the property as part of the application. Verifying access and confirming whether the property is inside city limits or unincorporated before submittal avoids delays and resubmittals.

Confirm Jurisdiction and Access Early

Floodplain Use Permits are issued separately from building permits and can take several weeks. Starting both processes at the same time keeps floodplain review from becoming a bottleneck.

Run Floodplain and Building Permits in Parallel

Permit Pushers prepares applications, navigates the Citizen Access Portal, and coordinates with Pinal County Building Safety, Environmental Health, Flood Control District, and Public Works to keep projects moving from application to issuance.

How Much Do Permits Cost in Pinal County?

Pinal County calculates building permit fees based on project valuation and square footage, with the fee structure approved by the Board of Supervisors under A.R.S. § 11-251.08. Fee tables are based on the 1994 Uniform Administrative Code and 2012 ICC Valuation Data, with plan review fees charged separately from permit fees.

A factor unique to Pinal County is the $20 Flood Control District fee assessed to all permits at the time of permit pickup, covering the District's review of washes, floodplains, fissures, and regional routes. This fee applies even for projects that don't require a separate Floodplain Use Permit.

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

Mechanical, plumbing, and electrical work each requires its own permit and an Arizona ROC-licensed contractor in the appropriate specialty classification. Environmental Health permits for septic systems, public pools, and food establishments are issued separately by the Environmental Health Division and have their own fee structure. Floodplain Use Permits issued by the Flood Control District also carry separate fees.

Frequently Asked Questions

The City of Maricopa is in Pinal County, not Maricopa County. This is one of the most common points of confusion in Arizona permitting.

The municipality is located in the northern part of Pinal County along the I-10 corridor, and permits within city limits are issued by the City of Maricopa Development Services Department.

Maricopa County itself is a separate jurisdiction with its own permitting departments.
San Tan Valley is one of the largest unincorporated communities in Arizona, located in the northwest portion of Pinal County.

Because San Tan Valley is not incorporated, all building permits within the community are issued by Pinal County Building Safety rather than by a city or town.
Yes, if your project is in a Special Flood Hazard Area. The Pinal County Flood Control District issues Floodplain Use Permits separately from building permits, and both are required before construction can begin in a floodplain.

For single-family residential projects, Floodplain Use Permits are typically issued within 2 to 5 weeks.

Starting the floodplain process at the same time as the building permit application keeps it from becoming a bottleneck.
Pinal County requires all residential building permit applicants to affirm that legal and physical access to the property exists as part of the application.

The county does not verify access on the applicant's behalf, and the issuance of a building permit does not guarantee or imply that legal access exists.

Property owners are responsible for confirming access through their own documentation.
Inspections are scheduled through Pinal County's automated inspection line at 520-866-6299.

Inspections can be scheduled up to three days in advance, and same-day inspections are available if requested by 6 a.m.
