Summary
Texas counties cannot zone, so unincorporated Hidalgo County has no shed size, height, or setback ordinance. A simple storage shed with no plumbing needs no county building permit, but the county Planning Department still requires a development permit for any structure and a floodplain permit in mapped flood zones.
Applicant acknowledges that a development permit is required for the construction of any structure prior to the commencement of improvements and the application fee shall be doubled for construction commencing prior to obtaining an approved application.
Full Breakdown
Sheds and detached accessory buildings in unincorporated Hidalgo County are not controlled by county zoning, because Texas counties have no general zoning authority and do not adopt a residential building code. There is no county limit on shed square footage, height, or lot-line setback the way a city ordinance sets one. The county Planning Department application does state that a development permit is required to construct any structure before improvements begin, and setbacks and finished-floor elevations must match the subdivision plat and deed restrictions. If the shed sits in a mapped flood zone (Zone A, AE, AH, or AO), a floodplain permit is required. A shed with a bathroom or living quarters would also need a septic (OSSF) permit.
Violations & Fines
Building a shed before obtaining the county development permit doubles the application fee, and placing a structure in a flood zone without a floodplain development permit and elevation certificate can block the required county clearance and utility service.
