Building Permits & Construction Costs in Houston, TX

In Houston, fence permits are generally required for any fence exceeding 6 feet in height. Fences placed on front property lines may be restricted to 4 feet. Always verify setbacks and utility lines (call 811 before digging).

Detached accessory structures (sheds, workshops) under 200 square feet may be exempt from a building permit, but must still comply with zoning setback requirements (usually 3-5 feet from side and rear property boundaries).

Decks attached to the primary residence or elevated more than 30 inches above the surrounding grade require a building permit. Detailed structural drawings showing footing sizes and joist spacing are usually required.

In Houston, complete roof tear-offs and replacements (re-roofing) typically require a building permit. This ensures proper decking inspection, ice-and-water barrier installation, and compliance with wind uplift standards. Placing a second layer of shingles over existing ones may be restricted or prohibited.

Installing solar photovoltaic (PV) panels requires both a building permit and an electrical permit. Plans must be submitted showing panel layouts, electrical schematics, and an engineering certification verifying that the existing roof structure can support the additional dead load of the solar arrays.

Replacing windows without altering the structural frame (retrofitting) usually requires a simple building permit. However, if the opening size is enlarged, a structural permit is mandatory. All replacement windows must comply with energy efficiency standards and bedroom emergency egress requirements.
