Phase 1 Environmental Site Assessment Cost in Texas
Typical Phase 1 ESA cost in Texas
$2,000–$4,500 per standard commercial parcel
Compiled from published 2026 industry cost guides (at the $2,000-$4,500 national baseline). Full methodology on the cost data page.
Texas sits right at the national baseline in the published cost guides, not a premium or a discount state, which is notable given how large its commercial real estate market is. A deep bench of environmental consulting firms competing for work across Houston, Dallas-Fort Worth, Austin, and San Antonio appears to keep pricing in line with the national average even though Texas has some of the highest-volume industrial and energy-sector due diligence work in the country.
What tends to drive cost up in Texas
Texas's oil and gas history shows up constantly in Phase 1 ESA findings, former well sites, pipeline easements, tank batteries, and refining or petrochemical-adjacent land uses are all recurring RECs along the Gulf Coast and in the Permian Basin region. A Houston-area Phase 1 ESA in particular tends to spend real time on historical land-use research given the region's petrochemical corridor.

Frequently asked questions: Texas
Is Texas cheaper for a Phase 1 ESA than other big states?
It's close to the national average rather than a discount, but it is notably cheaper than California or New York, likely reflecting the large number of environmental consulting firms competing for work statewide.
Do former oil and gas sites need extra scrutiny in Texas?
Yes. Former well sites, pipeline right-of-way corridors, and tank batteries are common recognized environmental conditions in Texas, and a competent Phase 1 ESA researches historical land use specifically for these features.
How fast can a Phase 1 ESA be done in the Houston area?
Standard turnaround nationally is 2 to 4 weeks; Houston's large base of environmental consultants means rush timelines (5 to 10 business days) are often available for a premium, the same as in most major Texas metros.
