Shed permit rules in Galveston County, TX — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
The county cannot set shed setbacks. In the City of Galveston, accessory structures must sit 3 feet from side and rear lines (0 to an alley) and 6 feet from any habitable structure. League City requires a permit for sheds over 200 square feet.
Texas counties have no zoning power, so unincorporated Galveston County imposes no shed setback or size limit; a building permit for septic/floodplain may still apply. In the City of Galveston, LDR Sec. 3.305 sets accessory-structure setbacks. In League City, storage sheds larger than 200 square feet require a residential building permit, and building a shed without a permit violates city ordinance. Always check the FEMA flood zone; coastal Galveston County has strict floodplain elevation rules.
In cities, building or placing a shed without the required permit is a code violation carrying stop-work orders and daily fines; unincorporated county has no shed ordinance to cite.
