Buying Land in Gregg County, Texas

No Groundwater District Yet -- But One Is Actively Being Formed

Case-by-case / verify locally

As of this writing, no part of Gregg County sits inside a groundwater conservation district, which means the general statewide rule of capture applies to groundwater production here without any local permitting, spacing, or metering requirement layered on top. That is changing: Gregg County's Commissioners Court voted in mid-2026 to join roughly 14 other East Texas counties overlying the Carrizo-Wilcox Aquifer in a joint effort to create a new regional groundwater conservation district, with a bill targeted for the Texas Legislature's 2027 session. See our standalone well-water page for the full detail -- if you're planning to drill in Gregg County in the next couple of years, this is worth tracking closely rather than assuming today's unregulated status is permanent.

No Confirmed County Subdivision Regulations for Unincorporated Land

Case-by-case / verify locally

This research did not locate a published, county-adopted subdivision-regulations document for unincorporated Gregg County, unlike several comparison counties in North and Central Texas that have posted detailed platting rules. That could mean the county's platting review is genuinely lighter-touch, or it could simply mean the governing document isn't posted where this research could find it -- either way, confirm directly with the Gregg County Judge's office or Commissioners Court before assuming a land split in the unincorporated county is either unregulated or follows a specific set of standards.

The County Health Department Handles Septic Permits Directly

Generally favorable

Gregg County Health Department holds TCEQ authorized-agent status for on-site sewage facilities, reviewing site evaluations and issuing OSSF permits under the statewide 30 TAC Chapter 285 rules rather than routing through a TCEQ regional office. Confirm current fees and site-evaluation requirements directly with the Health Department (903-237-2628) before budgeting a septic system.

A Century of Oil Development Sits Under Much of the County

Case-by-case / verify locally

Gregg County was ground zero for the East Texas Oilfield, discovered in October 1930 and still the largest oil reservoir ever found in the contiguous United States -- more than 30,000 wells were eventually drilled across the field's roughly 140,000 acres spanning Gregg and four neighboring counties. Gregg County is no longer a major producer (it ranks 72nd among Texas counties by current output), but that legacy well density means a real, non-zero chance that a given rural tract has an old plugged or unplugged well, an active lease, or severed mineral rights on it. Before buying raw land here, check Railroad Commission of Texas well records for the specific parcel and have a landman or title company confirm mineral-rights and lease status -- this is a genuinely more relevant diligence step in Gregg County than in most of the rest of the state.
