Living in Grayson County

Is Grayson County a good place to live?

Grayson County is where Collin County’s growth meets small-town and lake country. It grew about 13% from 2020 to July 2025, to roughly 153,600 residents, and had the largest net migration of the north-of-DFW counties we track.

The draw is jobs and value: Texas Instruments began production at its new Sherman semiconductor fab in December 2025, GlobalWafers has built a wafer plant next door, and home prices remain well below Collin County. Ten Twenty Realty’s home base is in Van Alstyne, at the county’s southern edge.

Buying land

Buying land & acreage in Grayson 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 and PenTex Energy serve much of the countryside; Sherman and Denison are Oncor areas with retail choice.
