Commercial Use & Occupancy Permits in Texas | PE-Stamped Packages

Texas cities require a certificate of occupancy for new construction, a change of use (an office becoming a restaurant, a warehouse becoming retail), a new tenant occupying space, and most build-outs that alter exits, occupancy loads, or structural elements. The application rides on a use permit or build-out permit that bundles site plan, fire, and structural review.

The change-of-use case is where engineering matters most: the building code reclassifies the space's occupancy category, and the new category carries higher floor live loads. A second-floor office converting to storage, or retail converting to fitness, may exceed what the existing structure was designed to carry — and the city will require a PE's verification before granting occupancy.

For change-of-use and heavy-occupancy applications, building departments want a licensed engineer's verification that the structure can carry the new use: floor live loads per the IBC's occupancy table, concentrated loads from equipment and storage racking, and any structural alterations the build-out introduced.

We evaluate the existing framing — beams, joists, and slabs — against the new use's requirements, and where capacity falls short we design the reinforcement: added beams, sistered framing, or strengthening of the slab. The stamped evaluation letter or calculation package goes into the occupancy application, and plan reviewers accept it because it addresses exactly what they check.

Occupancy review verifies the site supports the use: parking counts by occupancy category, accessible routes from parking and street to the entrance, fire apparatus access, and site drainage that meets the city's criteria. A change of use can change the required parking ratio — converting office to restaurant, for example, usually raises it — and a shortfall can stall the permit as badly as a structural deficiency.

We prepare the compliant site plan for the use permit, quantify parking and accessible-route compliance, and where a shortfall exists, design the layout or supporting documentation (shared-parking studies, variance applications) that resolves it. For full site design see our site plan engineering service.

The sequence: (1) we review your proposed use against the space and site, and tell you exactly which engineering pieces your city requires; (2) we perform the structural evaluation and prepare the stamped verification and site plan; (3) your contractor or architect assembles the full build-out package with our engineering included; (4) the city reviews — typically 2-4 weeks for change-of-use; (5) final inspections verify the work, and the certificate of occupancy is issued.

We respond to reviewer comments at no additional cost for the original scope, and most simple occupancy evaluations are delivered within a week. Call (833) 598-1772 with your address and proposed use — we'll tell you on the call what your city will require and quote the exact scope.

Structural verification letters for occupancy applications typically cost $750-$2,500. Floor live-load evaluations with reinforcement design run $2,000-$6,000. Use-permit site plan packages range $2,500-$8,000 depending on the site and city. Tenant improvement structural plans are quoted by scope — see our commercial structural engineering service.
