QD Design designs restaurants in Katy, Texas with architecture and sealed MEP engineering under one contract — floor plan, occupancy and egress analysis, Type I hood and kitchen exhaust design, grease waste, kitchen power, and COMcheck energy documentation in one coordinated permit set. We are a HUB-certified A/E firm based in Cypress (Houston metro), led by a Texas-licensed Professional Engineer, and restaurants are the largest single share of our portfolio.
What a Katy restaurant permit set includes
A restaurant permit package is really two designs that must agree: the architectural set (dining and kitchen layout, occupancy, egress, accessibility, finishes) and the MEP set (hood and exhaust per IMC 2021 and NFPA 96, makeup air, grease interceptor sizing, gas piping, three-phase kitchen power, and lighting compliance under IECC 2021 with COMcheck). Because one firm produces both, hood clearances, duct routing, and equipment schedules match before the reviewing jurisdiction ever sees the drawings — the coordination errors that stall split architect/engineer teams never reach plan review. See our restaurant design service for full scope.

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 I need both an architect and an MEP engineer to permit a restaurant in Katy?
For most commercial restaurant projects, yes — the reviewing jurisdiction expects architectural drawings plus mechanical, electrical, and plumbing plans sealed by a Texas-licensed engineer, and the kitchen exhaust design has to agree with the floor plan. QD Design produces both under one contract, so the set arrives at plan review already coordinated.
Who designs the kitchen hood and grease system?
Our in-house MEP engineers. Type I or Type II hood selection per IMC 2021, exhaust and makeup air, NFPA 96 clearances, fire-suppression coordination, gas piping, and grease interceptor sizing are all part of our standard restaurant scope — the same systems we permitted on the Golden Chick QSR in Humble and the multi-hood food hall on Bellaire Boulevard.
Who reviews restaurant 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. Restaurants also add health-department review of the kitchen layout, and TDLR accessibility review applies over the $50,000 threshold.
How long does restaurant design take?
Typical tenant-improvement restaurant packages run 3–5 weeks from contract to submittal, and answering plan-review comments until the permit is issued is included in our standard scope.
