Buying land
Buying land & acreage in Collin 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: Grayson-Collin Electric Co-op north of US-380, plus CoServ and Farmers Electric in some areas; most cities are Oncor areas with retail choice.
