Gilbert Building Permits — Cost, Timeline & Process

The Town of Gilbert requires a building permit for most construction, alteration, and repair work that affects structural, electrical, plumbing, or mechanical systems. Permits are issued by the Town of Gilbert Development Services Department — Building Safety Division, which also handles zoning clearances, plan review, and field inspections.

Gilbert is incorporated as a Town, not a city — making it one of the largest incorporated towns by population in the United States (over 267,000 residents). Despite its "town" designation, the permitting process is equivalent in scope and complexity to Arizona cities of comparable size. The Development Services Department handles the full range of residential, commercial, and industrial permit types.

Arizona has no mandatory statewide building code. Gilbert enforces its own locally adopted codes. Gilbert has adopted the 2018 International Codes (IBC, IRC, IMC, IPC, IFC, IECC) and the National Electrical Code (NEC), each with local Gilbert amendments. Gilbert is located in Maricopa County in the East Valley, adjacent to Mesa and Chandler.

When You Need a Permit

You generally need a Town of Gilbert building permit for:

• New construction, additions, and accessory structures including ADUs (Accessory Dwelling Units)
• Structural alterations, load-bearing wall changes, and foundation work
• Electrical, plumbing, and mechanical (HVAC) changes
• Reroofing and window or door openings in exterior walls
• Swimming pools, spas, and retaining walls above applicable height thresholds
• Solar photovoltaic (PV) system installations
• Demolition of any habitable structure

Minor cosmetic work (painting, floor coverings, cabinetry without plumbing or electrical changes) is typically exempt. When in doubt, contact Gilbert Building Safety before starting work.

OneStopShop — The Current Online Portal

Gilbert's current online self-service portal is OneStopShop.gilbertaz.gov. Applicants use it to register, submit supported applications, make payments, and access current Development Services workflows. Through the Town's online services you can:

• submit supported development and permit applications;
• use electronic plan-review services where applicable;
• pay fees online;
• look up permits; and
• schedule inspections through the Town's current online tools.

Permit Costs

Gilbert permit fees are established in the Development Services Fee Schedule published by the Town. Fees are typically calculated based on:

• Building permit fee — scales with project valuation
• Plan review fee — a percentage of the building permit fee
• Impact fees — for new construction or added square footage (water, wastewater, transportation, parks)
• Trade permit fees — separate fees for electrical, plumbing, and mechanical work

Do not rely on third-party fee estimates. Always check the current Gilbert Development Services Fee Schedule linked in the sources above for exact amounts.

Review Timing

Gilbert publishes Plan Review Timeframes and separate plan-review program guidance. Review duration depends on the project type, completeness, review program, and correction cycles. Use the current Development Services timeframe publication and permit record rather than generic week-or-month estimates.

The Process

1. Pre-submittal: Verify zoning and applicable codes for your parcel on the Gilbert zoning map
2. Plans: Prepare drawings stamped by a licensed Arizona architect or engineer where required
3. Submit through OneStopShop / current electronic plan review: Follow Gilbert's current online instructions for the applicable permit type
4. Plan review: Gilbert Building Safety reviews plans for building code, zoning, fire, and engineering compliance
5. Corrections: Respond to review comments through Gilbert's current electronic plan-review workflow and resubmit revised plans
6. Permit issuance: Pay remaining fees and download or receive the approved permit
7. Inspections: Schedule required inspections at each construction phase through eTRAKiT
8. Final: Pass final inspection and receive a Certificate of Occupancy where applicable

Inspections

Typical inspection stages for a residential project include:

• Footing and foundation
• Underground plumbing and electrical
• Framing
• Rough plumbing, electrical, and mechanical
• Insulation
• Drywall
• Final building and trade inspections

Schedule inspections through Gilbert's current online inspection service or by contacting Building & Fire staff. Submit inspection requests at least one business day in advance.

Common Reasons for Denial or Corrections

• Plans don't meet the 2018 International Codes as locally amended by Gilbert
• Missing structural calculations, energy compliance documentation, or design-professional stamps
• Zoning conflicts (setbacks, height limits, lot coverage, permitted use)
• Missing site or civil review items (drainage, right-of-way, water or wastewater clearances)
• Incomplete submittal or missing documents in the current electronic plan-review system
• HOA or private covenant review not completed (note: the Town does not enforce private CC&Rs)
