QD Design designs spas, salons, med-spas, and fitness studios in Katy, Texas — architecture plus sealed MEP engineering under one contract, including franchise prototype adaptation. We are a HUB-certified A/E firm based in Cypress (Houston metro), led by a Texas-licensed Professional Engineer.
What a Katy spa or salon permit set includes
Wellness buildouts are plumbing- and ventilation-heavy for their size: treatment-room HVAC that stays quiet and draft-free, hot-water systems sized for real demand, salon exhaust, laundry utilities, and lighting under IECC 2021 with COMcheck. The architectural side carries treatment-room layouts, accessibility under TDLR/TAS, and finish schedules that satisfy both franchisor standards and local amendments. One firm producing both keeps the set consistent before the reviewing jurisdiction reviews it. See our spa & salon design service.

- Lash-studio franchise prototype, Euless — repeatable rollout documentation.
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 an architect and engineer for a spa or salon buildout in Katy?
For most commercial spa, salon, and fitness buildouts, yes — treatment rooms, plumbing changes, and ventilation put the project past the threshold where the reviewing jurisdiction requires sealed MEP drawings alongside architectural plans. QD Design produces both under one contract.
Can you work from our franchisor’s prototype?
Yes — this is one of our specialties. We delivered the Hand & Stone massage spa in Pearland (our second location for that franchise), dual F45 + FS8 fitness studios in Katy on parallel permits, and a repeatable lash-studio prototype in Euless built for rollout.
Who reviews spa and salon 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 over the $50,000 threshold, and it ran in parallel on our Katy fitness studios and Cypress med-spa.
What MEP issues surprise spa owners most?
Hot-water demand and treatment-room ventilation. Massage and facial rooms need quiet, draft-free conditioning; salons add chemical exhaust considerations; fitness studios add outdoor air and electrical for equipment. We size these systems in the first pass so they don’t surface as plan-review comments.
