Phase 1 Environmental Site Assessment Cost in Hawaii
Phase 1 Environmental Site Assessment work in Hawaii follows the same federal standard as everywhere else in the country: ASTM E1527-21 and the EPA's All Appropriate Inquiries rule. Hawaii carries a premium of about 45% above the national baseline in the published 2026 cost guides, and every consultant working here still has to complete the same records review, site visit, and interviews the standard requires nationwide before a lender or a CERCLA liability-protection buyer will accept the report.
What tends to drive cost up in Hawaii
What changes state to state is which state-level agency's records sit alongside the federal sources (CERCLIS/Superfund, RCRA) every Phase 1 ESA checks. In Hawaii, that agency is the Hawaii Department of Health, Environmental Management Division. A consultant working in Hawaii should already have an established process for pulling those records; confirming they have done so before is a reasonable question to ask when comparing quotes.

Frequently asked questions: Hawaii
What does a Phase 1 ESA cost in Hawaii?
Published 2026 cost guides put Hawaii about 45% above the national baseline, putting a typical standard commercial parcel in the $2,900 to $6,525 range. See the full 50-state table for how that compares to neighboring states.
Does Hawaii have its own environmental review process?
Yes. The Hawaii Department of Health, Environmental Management Division runs Hawaii's state-level environmental programs separately from the federal AAI process. A Phase 1 ESA still has to meet the ASTM E1527-21 standard for CERCLA liability protection regardless; the state agency's records come into play as one more source a consultant checks, and separately if contamination is found or a state disclosure law applies.
How long does a Phase 1 ESA take in Hawaii?
The standard national turnaround of 2 to 4 weeks from authorization to final report applies in Hawaii the same as elsewhere. Rush service in 5 to 10 business days is commonly available from most firms for a premium, and the completed report is valid for 180 days from the site inspection under ASTM E1527-21.
