What does a typical Phase 1 ESA cost?

The cost of a Phase 1 environmental site assessment (ESA) can vary, but typically ranges from $3,000 to $5,000 on average. However, many factors impact the overall cost, such as:

  • Site Size – Costs increase for larger sites that require more time to assess. Complex sites with multiple buildings and uses also increase costs.
  • Location – Assessments in major metropolitan areas or regions with high living costs tend to cost more. More remote rural area assessments may cost less.
  • Scope of Work – A more comprehensive assessment with additional services like sampling, asbestos inspections, lead paint testing, etc. adds more to the costs.
  • Office vs Industrial Sites – Industrial sites tend to be more expensive due to increased risk of historical contamination from use and need for specialized expertise.
  • Expedited Assessment – Requiring faster turnaround times instead of standard 30 days can also increase fees.
  • Assessor Experience – Some consultants right out of college may charge less than those with decades of specific expertise. But experience is very valuable for these assessments.

While $3,000-$5,000 is typical, very complex properties could exceed $10,000 for a Phase 1 ESA. Simple site with few structures could potentially cost less than $3,000 in some areas. Assessor experience level and site complexity tend to be prime drivers of cost.
