When are Permit Required

Permits are required for nearly all improvements done to a residential or commercial property. Fences, driveways, roofing, swimming pools, as well as any electrical, mechanical, plumbing or general construction of a structure requires a building permit. A structure includes the main building as well as accessory buildings such as a storage unit, gazebo, etc.

The dismantling of a structure also requires a permit – a demolition permit. Nearly any commercial dismantling or remodeling will also require an asbestos survey (required by the State of Texas).

Understanding General Building Permits

Building Permits

 A Building permit is required in order to protect the health, safety and welfare of the public. It does so by providing the means for City officials to review the project design and to inspect the construction for minimum standards as required by the adopted Building Code and the City Code.

A building permit is required for new construction, additions, alteration, renovations, relocations, and repairs or rehabilitation of a building or structure. Electrical, Plumbing and  A/C and Heating may also be require. Your licensed contractor will know the requirements applicable.

The City requires all contractors to register before doing any work within the city limits. A list of licensed contractors is available at the Building Department.

For residential construction such as detached accessory structures, fences, swimming pools, etc. a site plan must be submitted with certain requirements.
