1 county-level rule, plus city-specific rules for 4 cities in Hidalgo County, Texas.
Verified from official government sources
Hidalgo County does NOT have an accessory dwelling unit (ADU) ordinance. Texas Local Government Code Chapter 233 limits county building-permit authority to commercial, public-accessible, and multifamily (4+ unit) structures, so single-family residential development in unincorporated areas is not subject to county zoning. The County Subdivision Rules permit no more than one single-family detached dwelling per platted lot. Cities such as McAllen, Edinburg, Mission, and Pharr regulate ADUs through their own zoning codes inside city limits.
