Relating to the authority of a county that borders the United Mexican States to regulate residential land use; creating a criminal offense.

SB 2593 allows counties bordering Mexico to establish zoning rules for residential development in unincorporated areas, including platted subdivisions and specific land tracts. It authorizes regulations on building size, lot coverage, housing density, setbacks, utilities, and permitted land uses. The bill requires public hearings and a majority vote by commissioners courts to adopt or amend rules, with stricter three-fourths approval needed if protested by 20% of affected landowners. Violations of these zoning regulations would be treated as criminal offenses under the bill's provisions.
