Land use and controls are referring to deed restrictions or municipal zoning. Most homes in residential subdivisions in Texas have deed restrictions that restrict their use to residential use. Deed restrictions also generally require you to get approval from the Homeowners Association before making additions or improvements to the home. They also covers issues such a car parking, yard maintenance, etc. Municipal zoning covers similar issues, but is enforced by the local municipality. Not all cities in Texas have zoning restrictions. The City of Houston does have zoning restrictions, but can enforce deed restrictions.
