What to Include in Your Phase 1 ESA Request

When soliciting quotes from environmental consultants, provide the following to ensure accurate scoping and pricing:

  • Property address and APN — enables the consultant to pre-screen regulatory databases before quoting
  • Property size (acreage and building square footage) — larger sites require more reconnaissance time
  • Known or suspected environmental history — prior uses, USTs, spills, or remediation you’re aware of
  • Lender name and loan program — some lenders have specific report requirements (e.g., SBA, HUD, CMBS) that affect scope and who can sign
  • Required turnaround — standard is 2–3 weeks; rush orders (3–5 days) add 40–50% to cost
  • Target closing date — drives urgency and whether a reliance letter or update letter will be needed later

Getting quotes from at least two consultants is standard practice. Cheapest is not always best: a low quote from an inexperienced firm that misses a REC can cost far more in Phase 2 ESA and remediation than you saved on the Phase 1.

Typical Phase 1 ESA Timeline

StepDuration
Quote and contract execution1–3 days
Regulatory database search2–5 days
Site reconnaissance visit1 day (scheduled within 3–7 days)
Historical records review3–7 days (concurrent with database search)
Report drafting and review3–5 days
Final report delivery14–21 days total (standard)
Rush delivery5–10 days total

Under ASTM E1527-21, a Phase I ESA is presumed viable when conducted within 180 days prior to the acquisition or transaction date (not the site visit date). If more than 180 days pass between transaction and completion of key components, an update letter is required. CMBS and SBA programs each set their own independent validity windows (12 months and 1 year respectively).

Lender Requirements for Multifamily Residential Properties

Risk Classification

Multifamily Residential properties are classified as Low environmental risk for Phase 1 ESA purposes — apartments, condos, townhomes. This property type carries a 1× cost multiplier versus standard commercial properties (residential use), resulting in a typical adjusted range of $2,000–$4,500 nationally.

What Lenders Require

Low-risk property types may qualify for streamlined environmental review under some lender programs, but Phase 1 ESA is still commonly required. SBA requires environmental investigation for all commercial real estate collateral. For loans over $250,000, a Records Search with Risk Assessment is required at minimum; a full Phase I ESA is triggered by the property’s NAICS code or risk findings, not a flat dollar amount. Fannie Mae and Freddie Mac routinely require Phase 1 ESA for all multifamily acquisitions. For low-risk property types like offices, medical offices, and retail, the Phase 1 ESA typically finds no RECs and closes quickly — making it primarily a liability protection document rather than a risk discovery tool. CMBS pools require current Phase 1 ESA (within 180 days) for all properties at origination. Even low-risk properties benefit from Phase 1 ESA because it establishes the baseline environmental condition, protecting buyers from liability for contamination introduced by prior owners under CERCLA’s innocent landowner defense.

Report Standards

All Phase 1 ESAs must follow ASTM E1527-21 — the current standard adopted in December 2022. Reports must be completed by a qualified Environmental Professional (EP) meeting the qualifications defined in the AAI rule. Lenders require the report to be addressed or include reliance language allowing them to rely on the findings. CMBS lenders typically require Phase I ESA within 12 months of loan origination. SBA accepts reports within one year of loan issuance. Under ASTM E1527-21, five time-sensitive components must be completed within 180 days of the acquisition/transaction date to invoke the innocent landowner defense.
