Do I need a P.E.-stamped MEP set for a tenant fit-out in Katy?

In most cases, yes. Texas Occupations Code 1001 requires MEP designs above certain thresholds to be sealed by a Texas-licensed Professional Engineer, and unsealed drawings can stall plan review. Pyra holds TBPE firm registration F-22556.

How much does commercial MEP design cost in Katy?

MEP design fees generally fall between roughly $0.50 and $3.00 per square foot, or about 2 to 8 percent of construction cost, driven mainly by equipment density and complexity. A restaurant with a Type I hood, gas piping and a grease interceptor sits at the high end; an open-plan office fit-out sits at the low end. Pyra quotes fixed fees rather than percentages.

What most often delays a commercial fit-out in Katy?

Utility and shell-system constraints rather than design. When a change of use pushes the connected load past what the existing transformer and service can carry, the resulting service upgrade moves onto the utility engineering queue, and distribution transformer lead times have run long through 2026. Run the connected-load calculation against the new program before design freezes.

Can an out-of-state engineer seal drawings for a permit in Katy?

Not unless they hold a Texas P.E. license and their firm holds the required firm registration in Texas.

Who pays for MEP engineering, the landlord or the tenant?

On a tenant fit-out it is usually the tenant, often reimbursed through a tenant improvement allowance. The lease governs it, and allowances sometimes exclude design fees entirely.

How fast can I get an MEP quote for a Katy project?

One business day on standard scope. Send the architectural set, equipment cuts if available, and a paragraph describing the work.

Does Pyra design fire alarm or fire sprinkler systems?

No. Those are separate licensed scopes handled by fire alarm and fire protection contractors. Pyra coordinates with them but does not perform that design.

Does Pyra handle construction administration?

Yes, and the same engineers who produced the drawings handle it: submittal review, RFI responses and site observation.

Katy permit notes

City of Katy Permit Department reviews MEP. Most growth-area addresses are actually unincorporated Harris/Fort Bend County.

Published: The 2026 Texas Commercial MEP Field Report

We surveyed Texas GCs, architects and developers and analysed 374 sealed commercial projects to find what actually breaks tenant fit-out MEP schedules — and what predicts the projects that stay on time. The findings are published and free to read.
