Do I Need a Permit for a Commercial Tenant Improvement in Texas?
Commercial tenant improvement permit requirements. When a TI needs a permit, the permit stack, stamped drawings, contractor licensing, and change-of-occupancy triggers.
Almost always yes — a commercial tenant improvement needs a building permit, usually with electrical, mechanical, and fire permits alongside it.
Texas-specific rules
In Texas the trades that dominate a tenant improvement are licensed by the state even though general contracting is not regulated the same way. Anyone performing non-exempt electrical work must be licensed by the Texas Department of Licensing and Regulation and must perform that work through a licensed electrical contractor, and air conditioning and refrigeration contractors must hold a TDLR ACR licence with an ACR contractor employed at each permanent location. One TDLR exemption is worth knowing before scoping a TI: a licensed ACR contractor may make the electrical connections for heating and air-conditioning equipment, and the disconnect serving it, WITHOUT a separate electrician licence.

When a Tenant Improvement Needs a Permit
Nearly any commercial tenant improvement that moves a wall, changes the electrical or mechanical layout, or alters exits needs a building permit. Cosmetic work — paint, carpet, and like-for-like fixture swaps — usually does not. The line is structural and life-safety impact, not cost: relocating a single non-bearing partition can trigger a permit while a far more expensive finish package does not. Because a tenant improvement is commercial rather than residential, plan review is typically more involved and the accessibility and fire provisions apply in full.
The Permit Stack
A tenant improvement rarely means one permit. The building permit is the parent, and electrical, mechanical, and plumbing permits are usually pulled alongside it by the respective subcontractors. Fire sprinkler and fire alarm work commonly needs separate review, sometimes by a fire district rather than the building department. Expect each trade permit to carry its own inspections, and expect the certificate of occupancy or completion to depend on all of them passing — one open trade permit can hold up the whole space.
Stamped Drawings and Who Prepares Them
Most jurisdictions require plans prepared by a licensed architect or engineer for commercial work, with the threshold set by floor area, occupant load, or the nature of the change rather than by a single national rule. Structural modifications almost always need an engineer stamp. Energy compliance documentation for the mechanical and lighting scope is commonly required as well. Confirm the stamping threshold with the building department before you commission drawings, because redrawing a set to add a stamp is slower and more expensive than commissioning it stamped.
Contractor Licensing Is a State Question
Who may legally perform a tenant improvement is decided at the state level, and the rules differ more than most people expect. Some states license contractors centrally and separate commercial from residential qualification; some register contractors instead, tied to workers compensation rather than a trade exam; and some leave general contracting to city or county licensing while still licensing the electrical and mechanical trades at state level. The consequences of getting it wrong range from a failed inspection to a contractor losing the right to lien the property. Check the requirement for your state before signing, not after.
Assume a commercial tenant improvement needs a building permit plus trade permits, and budget for plan review. Confirm three things early: whether your drawings need an architect or engineer stamp, whether the work changes the building's occupancy classification, and how your state licenses or registers the contractor doing the work.
