Environmental Site Assessment Cost in California
The cost of a Phase 1 Environmental Site Assessment in California ranges from $1,800 to $2,500 for most standard commercial properties. ALFA Environmental Assessment Services offers competitive flat-rate pricing throughout the state, with no hidden fees or surprise charges.
Why Costs Vary
Phase 1 ESA costs vary based on property size, complexity, location, and turnaround requirements. Urban properties in dense areas like San Francisco or Los Angeles may cost slightly more due to the complexity of historical research. Rural or agricultural properties may require additional travel time. ALFA Environmental provides a free, no-obligation cost estimate for every property.
