Princeton, Texas Building Permit Guide

The City of Princeton’s Development Services Department issues building and trade permits inside city limits, and every application, payment and inspection request goes through the EnerGov self-service portal. A new home under 4,000 sq ft carries a $1,500 permit fee plus $400 for plan review, and inspections requested before 5 p.m. are done the next business day, Monday to Thursday.

What requires a permit in Princeton?

Most construction and remodeling needs a City permit. Development Services lists these common cases:

Fences may be up to 6 feet tall in side and rear yards and 48 inches in front yards, and barbed wire is not allowed. Any retaining wall section 4 feet or taller needs engineered plans and a letter from the engineer after construction.

Princeton building department: who handles permitting

Development Services covers planning and zoning, permitting, building inspection, code compliance and GIS. City permits apply inside the city limits only. In the extraterritorial jurisdiction (ETJ), which reaches up to 2 miles beyond the limits, the City applies only its subdivision ordinance, under an interlocal agreement with Collin County: it reviews plats, stormwater, utilities and driveways, and no other City ordinance, zoning included, applies there. Land outside the city falls to Collin County, and since October 1, 2025 Princeton no longer provides fire service outside its limits under the old county agreement.

Princeton permit records and contractor registration

Permits are filed by record type in EnerGov: building, remodel, accessory, foundation, roofing, fence, pool, electrical, plumbing, mechanical, irrigation and alternative power source permits, among others. The City posts an EnerGov user guide next to the portal link.

• Contractor registration: general, electrical, plumbing, mechanical and irrigation contractors, sign contractors and backflow testers must register with the City before they can receive a permit. Registration costs $75 a year.
• Gas work: only a homeowner or a licensed master plumber can get the plumbing permit needed for a gas inspection, and the City releases gas service to Atmos, Si Energy or Centric only after a passed City inspection.
• Home backup power: generators and battery storage on one- and two-family homes may use a third-party plan reviewer and inspector under the state law in force since September 1, 2025, but a City electrical permit ($90) is still required before Oncor, Grayson-Collin Electric Co-op or TNMP gets a service release.
• Other applications: the Business License – Certificate of Occupancy application, development, plat, zoning, variance and specific use permit applications are posted on the Permitting page.

Princeton permit fees

Building fees come from Appendix A of the City’s code (fee schedule as published in May 2026), with the changes in Ordinance No. 2025-09-22, adopted September 22, 2025. Plan review is charged on top of the permit fee.

On the commercial table, a valuation between $100,001 and $500,000 pays $993.75 for the first $100,000 plus $5.60 for each additional $1,000. Water and wastewater impact fees ($3,026 and $1,963 per service unit in the code’s schedule) and park fees may be added when the permit is issued. The City’s fence FAQ still quotes a $25 fee, but the September 2025 ordinance raised it to $75.

Princeton trade permits

Development Services issues electrical, plumbing, mechanical and irrigation permits as separate EnerGov records, each at $90 under the fee schedule. Only registered contractors can pull them, except that a homeowner may pull a plumbing permit for gas work. Electrical work follows the 2023 National Electrical Code and plumbing the 2021 International Plumbing Code, both with City amendments.

Commercial fire protection systems are reviewed under the City’s fire fee schedule at $0.035 per sq ft of building area (minimum $60), and fire permit fees double if a system is installed before its permit is issued.

How to get a building permit in Princeton

Inspections in Princeton

Inspectors work Monday through Thursday, 7:30 a.m. to 5 p.m., and a request received before 5 p.m. is done the next business day in that window. (An older FAQ gives a midnight cutoff; the Building Inspections page sets 5 p.m.) Inspections cover foundation, framing, electrical, plumbing and final stages, and the work must stay accessible until approved. Inspectors sign the inspection record when work passes and leave a correction notice when it fails; a re-inspection costs $75. The Building Official can extend a permit deadline in some cases.

Floodplain: floodplains run mainly along Sister Grove Creek. Building in one requires permits, and Princeton requires freeboard, typically 1 to 2 feet above the base flood elevation.

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
