Thompsons, TX Permit Fees (2026)

Building permit fees and building permit fees for Thompsons, straight from the official fee schedule, with a free permit fee calculator below.

Fort Bend County's Engineering Department issues development permits in the Town of Thompsons under a 2014 interlocal agreement that has permit fees paid directly to the county, and the Town's flood ordinance sets the permit fee by the Fort Bend County fee schedule. The Town approved a fire code agreement with the county in July 2026; whether the county has signed it is unconfirmed, so ask whether the Fire Marshal fees shown apply to commercial buildings in the Town. See the Fort Bend County fee schedule

The Town of Thompsons publishes no building, electrical, plumbing or mechanical permit fee. Fort Bend County issues development permits in the Town on the county's schedule: a flat development permit ($100, or $150 in a floodplain) for new structures, additions, floodplain work and similar development. Fire Marshal fees on commercial, public and larger multifamily buildings apply only once the county fire code agreement the Town approved in July 2026 is in force. Work started without a permit is charged double. Town subdivision, plat and civil construction review and inspection fees (Ordinance 189) are separate.

How to Apply for a Permit in Thompsons

Fort Bend County's Engineering Department issues development permits inside the Town of Thompsons under an interlocal agreement. Apply online through the county's MyGovernmentOnline portal at mgoconnect.org (create an account, then a Residential or Commercial Development Permit application); a Residential Development Permit is required for any new structure on residential property, or addition to an existing structure, of 400 square feet or more, and work in the floodplain needs a permit too. New structures need a CenterPoint address verification letter, and an application includes a site plan, the recorded deed, a metes and bounds description for property outside a platted subdivision, septic design drawings where a septic system will serve the structure, and other agencies' permits. Commercial projects first get County Engineer approval of civil construction drawings. Fees are paid to the county, and work started before the permit is issued pays double. Applications, power release and inspection requests go to Permits@fbctx.gov or 281-633-7500. Subdivision plats and civil construction plans go to the Town of Thompsons, City Hall, 520 Thompson Oil Field Road, 281-343-9929.
