Mustang, Oklahoma Building Permit Guide

In Mustang, the City’s Community Development Department at 1501 N. Mustang Road reviews plans, issues building, electrical, plumbing and mechanical permits and inspects the work, and all applications go through the GovWell portal. A house permit is $20 plus 5 cents per square foot and the $4.50 state fee, plus a $50 plan review, and the City allows three full days to review house plans.

What needs a permit in Mustang?

The City’s fee schedule and construction guides list these permits. Electrical, plumbing and mechanical work each need their own permit, and subcontractors buy their own.

Improvements in a state highway right-of-way also need a permit from the Oklahoma Department of Transportation.

Who handles permitting in Mustang?

Community Development handles plan review, permits, contractor and business licences, zoning and floodplain management for property inside city limits. Mustang’s building code amendments make the community development director the building official, and the department names Wayne Blethrow as Chief Building Official. Mustang is on the State Fire Marshal’s July 2026 list of cities that do their own plan review, permitting and inspections.

Mustang’s permits stop at the city limits. Unincorporated Canadian County has no general building permit; the county requires permits only for floodplain and county right-of-way work; see our Canadian County guide.

Applying through GovWell

Mustang uses GovWell for every building permit, contractor licence, business licence and planning or zoning application. First-time users create an account before submitting, and the department answers questions about the portal at 405-376-9873. PDF versions of the City’s forms are kept in the department’s online document library.

All general contractors and subcontractors must hold a City of Mustang licence before a permit is issued, along with any state licence their trade needs. General contractor licences and electrical, plumbing and mechanical contractor licences each cost $100, with a $50 renewal, and every contractor licence expires on October 31.

Mustang permit fees

These figures are from the City’s Permits & Fees page and match Section 42-18 of the City Code. Every permit carries a $4.50 state fee, and the smallest permit costs $54.50 including that fee.

For example, a 2,000 sq ft house has a building permit fee of $120 ($20 plus $100) and the $4.50 state fee, plus $50 for plan review and the $50 park fee, before trade permits. Utility connection and park fees are paid when the building permit is bought. A new house that connects to City sewer also pays the $1,000 sewer infrastructure impact fee when the building permit application is filed (City Code Section 42-118), plus water meter and connection charges, which Ordinance 1350 raised for new construction on May 5, 2026.

Electrical, plumbing and mechanical permits

Community Development issues the trade permits, and each licensed subcontractor buys its own. The same rates apply to homes and commercial buildings.

Commercial plans may be sent to the City’s consulting fire engineer for review, and the applicant pays the consultant’s fee. Gas service is not released until the service line and appliances pass inspection.

Plans and documents

The Residential Construction Guide requires an Oklahoma architect’s or engineer’s seal where any part of a structure is over two stories, below grade, or has an unsupported span of 30 feet or more. If no fire hydrant is within 600 feet, the plans must show alternative fire protection. The City allows three full days to review house plans; commercial and industrial review takes longer.

How to get a Mustang building permit

Inspections in Mustang

Inspections are usually available within 24 hours of the request, on business days only, and the City encourages booking an appointment. The general contractor calls for site and footing inspections before the pour, and each trade contractor calls for its own ground, rough-in, top-out and final inspections. Rough-ins and top-outs can be held until all trades are ready, so they are inspected in one trip.

A final inspection is done only when the building is complete, including driveways, sidewalks, flooring and light fixtures. A reinspection costs $50 the first time and $100 after that. Water meters can take up to 2 weeks to set, and a temporary certificate of occupancy is available only on a limited basis once fire and life safety items are complete. Permits are valid for one year, and renewals may be available for a small fee.

Local Mustang details

Floodplain: Mustang takes part in the National Flood Insurance Program. Building or excavating in or near the 100-year floodplain can also require a Floodplain Development Permit under Chapter 50, Article II of the City code, usually with an engineer, surveyor or architect. Most new and substantially improved habitable buildings must have the lowest floor at least 1 foot above the base flood elevation, certified by a registered professional.

Commercial sites: required storm water detention must be in place before any impervious surface is created, and fire hydrants must be installed and tested before combustible materials arrive.

Design policies: the department has adopted policies on clear spans and footing design, available by calling 405-376-9873.

Building codes in Mustang

The City’s commercial permits page says Mustang follows the 2018 International codes as amended and adopted by the Oklahoma Uniform Building Code Commission, and the 2020 National Electrical Code. The online Code of Ordinances (version of July 30, 2024) adopts the 2018 building, existing building and residential codes with local amendments. The older Residential and Commercial Construction Guides still name the 2015 editions.

Oklahoma sets statewide minimum codes (the 2024 editions since September 14, 2026) that cities enforce and may strengthen; most counties issue no building permits for unincorporated land, though a few do. Oklahoma rules
