Gainesville, Texas Building Permit Guide

Inside Gainesville city limits, building, electrical, plumbing and mechanical permits come from the City’s Community Development department at 104 W. Hird St., and applications go through the EnerGov self-service portal or by email. A new house costs $1.15 per square foot ($1,575 minimum) under the fee schedule effective October 1, 2026, with impact fees added, and inspections requested before 4:00 p.m. are processed for the next day.

What requires a permit in Gainesville?

Each accessory structure needs its own permit, and any wiring, plumbing or mechanical work on it is permitted separately. Boat docks on Moss Lake also need a City building permit.

Gainesville building department: who handles permitting

The Permits & Building Inspection division of Community Development reviews plans, issues building and trade permits, registers contractors and schedules inspections for property inside the city. It works from the Public Works Facility rather than City Hall. Commercial plans are passed to every other City department involved, and the permit is approved only once all of them have signed off.

Land outside the city limits is unincorporated Cooke County. Septic systems on both sides of the city limit are permitted by Cooke County (a conventional residential system was $410 under its 2026 process): TCEQ lists the City of Gainesville’s septic program as administered by the County.

EnerGov filing and contractor registration

Create an EnerGov account to apply, upload plans, pay and request inspections; the City publishes an online citizen guide for the portal. You can instead print the application for the job type (residential building, commercial building, residential accessory, sign, fire protection equipment, Moss Lake dock or tent) and email it to cs@cogtx.org or bring it to the office.

No contractor can obtain a permit without registering with the City first. Registration takes the application, a copy of the driver’s licence, a liability insurance certificate for at least $1,000,000 per occurrence naming the City as holder, any state trade licence, and the fee: $210 the first year and $105 to renew, every year. Registered contractors receive an ID card. The registration form does not treat private citizens doing their own work as contractors.

On new homes and new commercial buildings, every electrical, plumbing and mechanical subcontractor must “validate” on the job by filing the trade validation application. Validation is free because the trade fees are charged on the parent permit, and the building permit is not issued until all three trades have validated.

Gainesville permit fees

Fees come from the City fee schedule effective October 1, 2026. Impact fees under Ordinance 1625-08-2026 are added to all new residential and commercial construction and are not included below.

For example, a 2,000 sq ft new house is $2,300 before impact fees. Commercial and multi-family work is charged on construction value, which includes plan review: $275 up to $10,000, rising to $1,590 for the first $100,001 plus $9 per additional $1,000, and $8,415 for the first $1,000,001 plus $7 per additional $1,000. Commercial trade, fence, roofing and fire system permits use the same valuation table.

Utility connections are billed separately: for example a 1-inch water tap is $1,919.08, a 3/4-inch meter $747.20 and a 4-inch sewer tap $1,561.38, and accounts outside the city limits pay 150% of the in-city rates.

Gainesville trade and fire permits

Electrical, plumbing and mechanical permits are issued by Community Development, and plumbers, electricians and air-conditioning contractors must hold a state licence as well as City registration. On a remodel or accessory building each trade pulls its own $160 permit; on a new house the trades validate on the building permit instead.

Fire alarm and sprinkler work needs a Fire Protection Equipment Permit, submitted as three paper sets plus a PDF, and fire system contractors register with the City like other trades. Sprinkler, alarm and underground fire line permits are priced on the commercial valuation table, and kitchen hood suppression systems are $300.

Plans and documents to submit

An engineered slab design must be filed before the permit is issued, with the engineer’s letter confirming the pour after it is done. Drawings marked “Not for Construction” or “For Pricing Only” are refused. For commercial jobs, Community Development emails plan review comments within 10 business days of a complete submittal. A shed, fence or carport application needs only a plot plan at 1 in = 20 ft or 1 in = 100 ft on paper at least 8½ by 11 inches.

How to apply for a Gainesville building permit

An accessory permit becomes void if work does not start within 180 days, or if work stops for 180 days at any point.

Inspections in Gainesville

Request inspections in EnerGov or by calling 940-668-4799 with the address or permit number and the inspection type; do not call inspectors directly. Requests made before 4:00 p.m. are processed for the next day, the City does not do same-day inspections, and inspections are generally made within 24 to 36 hours, excluding weekends and holidays.

Keep all work exposed until it passes. An inspection fails if the work is not ready or nobody is on site to meet the inspector, and the re-inspection fee must be paid in advance. Manufactured home permits cover the meter base, sewer and water connections, gas test, HVAC, disconnect and tie-down inspections. A commercial building needs a Certificate of Occupancy application approved before anyone occupies it, along with any backflow certification and special inspection reports.

Local Gainesville details that matter

Codes: the City’s Construction Guidelines list the 2021 International Building, Residential, Plumbing, Fuel Gas, Mechanical, Property Maintenance, Energy Conservation and Fire Codes and the 2020 National Electrical Code. The older Commercial Building Process & Guide still names the 2015 editions, so design commercial work to the 2021 list. Energy reports are required for all new homes and commercial buildings.

Floodplain: no construction permit is issued in the floodplain until the Flood Hazard Development Application and elevation certificate are approved; the City’s decision tree sets out what each project must provide.

Asbestos and accessibility: commercial additions, remodels and repairs need an asbestos study before the permit, and the job must be notified to the state asbestos program at least 10 days before work starts. Projects with accessibility elements carry a TDLR project number on the application or plans.

Moss Lake: dock construction is $1.15 per sq ft ($550 minimum) and needs a site plan, survey and dimensioned drawing, and docks also carry an annual permit.

Texas building code

Texas has no single statewide building code: state law makes the International Residential Code the base code for homes in cities and the International Building Code the base for commercial buildings, with each city choosing the edition and its own amendments, while the National Electrical Code and the energy code apply statewide. Outside city limits most counties issue no building permits for homes. Texas building code rules
