Katy Project Experience

Permitting in Katy

“Katy” spans three counties and two review worlds: inside the City of Katy limits, the city’s permit office reviews your project; the far larger unincorporated areas run through Harris County or Fort Bend County. Our F45 + FS8 dual fitness studios at 3170 Peek Road were permitted through Harris County with parallel TDLR filings. Knowing which reviewer your address answers to is step one — we confirm it before we propose. Statewide, any Texas commercial project valued over the $50,000 statutory threshold also requires TDLR registration and Texas Accessibility Standards (TAS) review — we file the registration and coordinate the accessibility review as part of the package.

Frequently Asked Questions

Do you have completed projects in Katy?

Yes — the F45 + FS8 dual fitness studios at 3170 Peek Road, designed as one architecture + MEP package with parallel Harris County permits and TDLR filings.

Who reviews commercial permits in Katy?

It depends on the address: inside the City of Katy limits, the city reviews; the much larger unincorporated areas run through Harris County or Fort Bend County. TDLR accessibility review applies statewide over the $50,000 threshold, and we file it as part of the package.

How fast can you deliver a permit set?

Typical tenant-improvement packages run 3–5 weeks from contract to submittal. On the fast end, our 25,250 SF Star Pipe industrial renovation in Houston had schematic design approved 7 days after signing. Answering plan-review comments until the permit is issued is standard scope.
