Remodel / Addition Permit
Also known as: alteration permit, addition permit, renovation permit
A permit covering interior remodels, structural alterations, or square-footage additions to an existing building.
A remodel or addition permit covers construction work that alters the structure, systems, or footprint of an existing building without razing it entirely. In Texas, this category includes kitchen and bath remodels involving structural or systems work, room additions, garage conversions, second-story additions, and commercial tenant improvements. Required documentation varies by scope: a simple remodel may require only basic drawings, while a large addition requires full architectural and engineering packages. Both residential and commercial projects fall under this work class.
Why it matters for contractors
Remodel and addition permits are the highest-frequency permit category in most Texas cities and often represent projects underway with an active GC — giving specialty trades a real-time call list for immediate subcontract opportunities.
