Phase 1 ESA Cost in Texas: 2026 Pricing Guide

Phase 1 Environmental Site Assessments in Texas typically cost between $1,500 and $3,500 for standard commercial properties. Texas generally tracks the lower end of the national range, though properties with petroleum history — extremely common in Texas — can require more records work and push costs higher.

Phase 1 ESA cost in Texas at a glance

The ranges below reflect typical pricing from environmental consulting firms for standard commercial properties in Texas. Houston, Dallas-Fort Worth, and Austin are the largest markets — pricing in those metros is broadly consistent with statewide ranges, though firms with high demand in tight urban markets may price toward the upper end.

Small commercial property (standard use history)$1,500 – $2,200
Mid-size commercial or mixed-use property$2,200 – $3,500
Large property or complex prior use$3,500 – $5,500
Industrial site, oil/gas-adjacent, or multiple parcels$5,000 – $8,000+
Rush turnaround (5 business days or under)+$500 – $1,000

What drives Phase 1 ESA costs in Texas

Texas pricing is generally lower than coastal states, but several state-specific factors can push individual assessments well above average.

Petroleum storage tank history

Texas has an extensive history of underground storage tanks (USTs) connected to fueling operations, oil field service businesses, and industrial facilities. Former gas stations — many now redeveloped into commercial properties — are among the most commonly flagged RECs in Texas Phase 1 ESAs. Properties with petroleum history require more database research and regulatory file review.

Oil and gas proximity

Properties near or formerly part of oil and gas operations require consultants to research production records, pipeline rights-of-way, and historical drilling activity. In the Permian Basin, Eagle Ford Shale corridor, and East Texas fields, these checks add research time and sometimes cost.

Agricultural chemical use

Texas has large acreage of former and active agricultural land, particularly in Central and West Texas. Properties with farming history may have herbicide, pesticide, or fertilizer contamination — a recognized REC type that adds records review time.

Large site acreage

Texas commercial and industrial properties tend to be larger than comparable sites in dense coastal markets. More acreage means more site area to walk, more buildings to inspect, and sometimes more records to pull — all of which affect cost.

Distance from consulting firms

Environmental consulting firms are concentrated in Houston, Dallas-Fort Worth, San Antonio, and Austin. Sites in rural West Texas or the Panhandle may incur travel time charges — the additional cost varies by distance and is typically quoted separately by the consulting firm.

Texas environmental regulations and the Phase 1 ESA

Phase 1 ESAs in Texas follow ASTM E1527-21 and the EPA's AAI rule. The Texas Commission on Environmental Quality (TCEQ) does not impose a separate state standard for Phase 1 ESAs, but it plays an important role if investigation goes further.

TCEQ oversight

The Texas Commission on Environmental Quality (TCEQ) is Texas's primary environmental regulatory agency. TCEQ oversees remediation of contaminated sites, administers the petroleum storage tank program, and issues regulatory database records that consultants pull during Phase 1 records review.

Voluntary Cleanup Program (VCP)

TCEQ's Voluntary Cleanup Program (tceq.texas.gov/remediation/vcp) provides liability relief for parties who voluntarily clean up contaminated sites. As of August 2024, TCEQ had received over 3,300 VCP applications and issued more than 2,800 certificates of completion. A VCP certificate on a target property is material information in a Phase 1 ESA.

Petroleum Storage Tank Program

TCEQ administers Texas's petroleum storage tank (PST) program, which tracks leaking UST sites statewide. Consultants search TCEQ's PST database during Phase 1 records review — properties near open PST cases are flagged as RECs.

VCP liability release

When a site completes TCEQ's VCP process, TCEQ releases non-responsible parties from state cleanup liability. VCP completion does not address federal CERCLA liability or third-party tort claims. A completed VCP on a target property is nonetheless material in Phase 1 due diligence — it provides meaningful state-level liability protection to a buyer.

What's included in every Phase 1 ESA

Every ASTM E1527-21 compliant Phase 1 ESA in Texas includes the same four required components: records review (including TCEQ regulatory databases), site reconnaissance, interviews with owners and occupants, and a written report signed by a licensed Environmental Professional.

Per the EPA's AAI rule, key activities including interviews, the on-site inspection, and government records reviews must be completed within 180 days before property acquisition. The full assessment must be completed or updated within one year. See the full breakdown of what a Phase 1 ESA includes.

If a REC is found: Phase 2 ESA in Texas

Petroleum RECs often lead to TCEQ-regulated Phase 2 investigations

When a Texas Phase 1 identifies petroleum-related RECs — the most common type in the state — the resulting Phase 2 typically falls under TCEQ's petroleum storage tank program. If remediation is required, TCEQ administers the cleanup process and may provide access to the TCEQ Petroleum Storage Tank Remediation (PSTR) Fund for eligible responsible parties.

Not every REC confirms contamination — many Texas Phase 2s come back clean.
TCEQ's VCP is a well-established path to liability clearance for Texas contaminated properties.
It is common in practice for deals with RECs to proceed — typically with price adjustments or remediation escrow, though outcomes vary by contamination type and lender requirements.
