In Bexar County, storage sheds under 120 square feet without electrical or plumbing generally do not require a building permit. Larger sheds require permits under the 2021 International Building Code adopted by the county in 2024.
Bexar County adopted the 2021 International Building and Fire Codes effective January 1, 2024. Under these codes, detached accessory structures (sheds) of 120 square feet or less, single-story, without electrical or plumbing, do not require a building permit. Sheds over 120 square feet require a permit through the county or city depending on jurisdiction. All sheds must comply with zoning setbacks — typically 5 feet from rear and side property lines. Sheds must be in the rear yard. Within San Antonio, the Development Services Department handles shed permits. Prefabricated sheds still require a permit if over 120 square feet.
Unpermitted sheds may be cited as building code violations with fines up to $2,000 per day. Stop-work orders and retroactive permit requirements apply.
