Tenant Improvement and Interior Build-Outs in Irving, TX

Yes, in most cases. Tenant improvement work that involves MEP system changes, partition construction, ceiling modifications, or changes to the fire alarm or sprinkler system requires a City of Irving building alteration permit. Cosmetic-only TI — paint, carpet, and minor finish replacement — may not require a permit, but any work touching the MEP, structural, or life-safety systems does. Medical suite TI always requires a permit regardless of scope.

City of Irving commercial alteration permit review for tenant improvement projects typically runs three to four weeks from a complete submission. Medical office TI permits may take slightly longer if the Fire Marshal's office requires additional review for occupancy classification changes. We pre-screen TI permit submissions against City of Irving requirements before submitting to reduce the likelihood of additional comment rounds.

NFPA 99 medical gas rough-in in a clinical TI suite involves installing copper piping for oxygen, medical air, vacuum, and — if required — nitrous oxide from the building's bulk medical gas source to the clinical rooms. Zone valve boxes are installed at the entrance to each clinical zone to allow individual zones to be isolated without interrupting gas service to other areas. The piping is pressure tested before walls are closed, and the completed system is certified by an ASSE 6010-certified medical gas certifier before the Certificate of Occupancy is issued for the clinical suite.

A straightforward corporate office TI of 5,000 to 8,000 square feet with standard open-plan, conference room, and small office configuration can typically be delivered in 10 to 12 weeks from permit issuance if subcontractors are procured during the permit review period and the tenant's design decisions are finalized before construction begins. Higher-finish executive suites with custom millwork, specialty ceiling systems, or premium flooring may require 14 to 16 weeks. We provide project-specific schedule estimates during preconstruction once the scope and finish level are defined.

Yes. TI build-outs in Las Colinas Class A office buildings require coordination with the property management team for access scheduling, freight elevator reservation, Oncor electrical service coordination, and base building system interface — including HVAC ductwork connections to the base building VAV system and sprinkler main tie-in for head relocations. We establish that coordination protocol with the property manager during preconstruction and maintain it throughout the construction phase.
