Buying land

Buying land & acreage in Rockwall County

Outside city limits, county land is mostly unincorporated, so the rules come from the county, the deed and the utility providers rather than a city. That makes due diligence before you make an offer especially important.

Texas counties generally can’t zone land outside city limits, so deed restrictions, HOA rules, floodplain maps, septic permits and nearby cities’ ETJ subdivision rules decide what you can build.

  • Survey and boundary lines
  • Legal, recorded road access
  • Water: city, water supply corporation or well
  • Septic suitability (OSSF permit)
  • FEMA floodplain
  • Deed restrictions and HOA
  • Mineral rights
  • Ag or wildlife valuation

Rural electric: Most cities are Oncor areas with retail choice; Farmers Electric Co-op serves some rural areas.
