Mesa Building Permits — Cost, Timeline & Process

Last updated: Verified:

Mesa's Development Services Department administers land-use planning, plan review, permitting, and building inspections.

Current Codes

Mesa's current technical-code package took effect January 8, 2026 and includes the 2024 IBC, IRC, IFC, IPC, IMC, IFGC, IEBC, IECC, and ISPSC, together with the 2023 NEC, subject to Mesa amendments. The City states that permit applications submitted on or after the effective date use the 2024 package, subject to published transition provisions for certain earlier designs and standard plans.

DIMES

Mesa uses DIMES as its current development-services record and permitting system. Current City inspection guidance directs users to the DIMES record to view corrections and schedule, reschedule, or cancel inspections. Remove remaining references that tell current applicants to use ACA Mesa for permit submission or inspections.

When You Need a Permit

Permit-required work generally includes new construction and additions, structural alterations, regulated trade work, many roofing and exterior-opening projects, pools and other regulated structures, and demolition. Use Mesa's current permit guidance for exemptions and project-specific thresholds.

Fees

Mesa's current Development Services pages note that Water and Wastewater Capacity Fees took effect January 1, 2026, with the full ¾-inch and 1-inch meter fees effective July 1, 2026 after the phase-in period. Other building and development fees depend on permit type and scope; use current City fee schedules.

Review Timing

Use Mesa's current published plan-review targets for the applicable permit type rather than generic estimates. Targets are service goals, not guarantees of total permit duration, and corrections or additional review disciplines can extend the process.

Process

  1. Confirm zoning and the applicable 2024 code package.
  2. Prepare the plans and supporting documents required for the permit type.
  3. Submit through DIMES.
  4. Complete applicable plan-review disciplines.
  5. Respond to corrections in the current record and resubmit as directed.
  6. Pay required fees and obtain the permit.
  7. Schedule required inspections through DIMES or the City's current automated inspection options.
  8. Complete final inspections and obtain a Certificate of Occupancy when required.

Inspections and Permit Activity

Mesa states that construction permits expire if work does not commence within 180 days of issuance, and a permit becomes void if no work and inspection activity occurs within 180 days. Required inspections must occur before work is concealed or covered. Follow the current City instructions for the specific permit record.

Common Correction Issues

  • Noncompliance with Mesa's 2024 I-Code package, 2023 NEC, or local amendments
  • Missing structural, energy, or professional documentation when required
  • Zoning or site-development conflicts
  • Missing civil, drainage, right-of-way, water, or sewer information where applicable
  • Incomplete DIMES submittal

FAQ

How do I apply for a building permit in Mesa?
Most building permit applications are submitted through ACA Mesa (Accela Citizen Access) at aca-prod.accela.com/MESA, the City of Mesa's online permitting portal. You create an account, upload plans for electronic plan review, pay fees, and schedule inspections in one place. In-person service is also available at the Mesa Development Services Department.
How much does a building permit cost in Mesa?
Mesa building permit fees are calculated from project valuation, with separate plan review, inspection, and impact fees. The City publishes an official Development Services Fee Schedule; exact amounts depend on your project's scope and valuation. See the Mesa fee schedule linked in the sources for current rates. Do not rely on third-party estimates.
How long does plan review take in Mesa?
Review timelines vary by project type and workload. Simple over-the-counter permits (like-for-like replacements, minor repairs) may be issued the same day or within a few business days. Standard residential plan review and commercial projects typically require multiple weeks for the first review cycle. Check with Mesa Development Services for current turnaround estimates.
Which building codes does Mesa use?
Mesa has adopted the 2018 International Building Code (IBC), 2018 International Residential Code (IRC), 2018 International Mechanical Code (IMC), 2018 International Plumbing Code (IPC), 2018 International Fire Code (IFC), 2018 International Fuel Gas Code (IFGC), 2018 International Energy Conservation Code (IECC), and the National Electrical Code (NEC), each with local Mesa amendments. Arizona has no mandatory statewide building code — Mesa enforces its own locally adopted codes.
How do I schedule a building inspection in Mesa?
Request inspections through the ACA Mesa portal at aca-prod.accela.com/MESA. You can also contact the Mesa Development Services Department directly by phone. Submit inspection requests at least one business day in advance to ensure scheduling.
