Hidalgo County
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.

Mcallen FAQ
What counts as lot coverage?

Pharr FAQ
Is there a lot-coverage limit in unincorporated Hidalgo County?
No. Counties have no zoning, so there is no county coverage or floor-area limit outside city limits. The county reviews subdivision plats for lot layout under Chapter 232, but not building coverage.
What does the county regulate about lots?
Subdivision platting. Under Local Government Code 232.001, dividing a tract outside a city into parts requires a plat stating each lot's dimensions. Coverage caps come from deed restrictions or a city, not the county.
