Summary
Hidalgo County sets no lot-coverage or floor-area ratio limit in unincorporated areas because Texas counties have no zoning authority. The county's land control is subdivision platting (lot layout under Local Government Code Chapter 232), not coverage. Coverage caps, if any, come from deed restrictions or a city inside city limits.
The owner of a tract of land located outside the limits of a municipality must have a plat of the subdivision prepared if the owner divides the tract into two or more parts to lay out a subdivision of the tract, including an addition.
Full Breakdown
There is no county maximum lot-coverage percentage or floor-area ratio for unincorporated property, because Hidalgo County has no zoning power to set one. The county regulates subdivision platting: under Local Government Code Chapter 232 it reviews plats for lot layout, streets, drainage, water, and sewer. Section 232.001(a) requires the owner of a tract outside a municipality to have a plat prepared when dividing it to lay out a subdivision. That review addresses how land is divided, not how much a building may cover. Coverage limits, where they exist, come from deed restrictions and Property Code Chapter 202 covenants. Inside a city, that city's zoning sets lot-coverage and FAR limits. On an unincorporated lot without covenants, the county imposes no cap.
Violations & Fines
No county lot-coverage citation applies in unincorporated areas. Subdividing land without a required plat violates Local Government Code Chapter 232 and can block sales and permits. Deed-restriction coverage limits are enforced civilly; city coverage limits are enforced by that city.
