Phase 1 ESA

A Phase 1 Environmental Site Assessment is a fundamental part of the real estate due diligence process and provides critical information about environmental liabilities associated with a property being purchased.

What Is A Phase 1 ESA?

A Phase I Environmental Site Assessment (Phase 1 ESA) is an investigation of a property’s current and historical use. The process views and investigates a property in regards to former use in order to determine if there is a potential for hazardous conditions that might be present on the property. Typically, a Phase 1 environmental study involves an on-site inspection by an environmental firm with detailed photography to document conditions.

Lenders require a Phase 1 Environmental Site Assessment for all properties that are greater than 4 units. 100% of the time, lenders will require a Phase 1 study for commercial properties. For multifamily properties – it can go either way. A Phase 1 ESA interviews with past and present building occupants, and with owners of neighboring properties are also conducted to validate past uses. A Phase 1 ESA does not involve any testing of things like paint, soil, or moisture, though a visual inspection may indicate the presence of hazardous materials.

How Much Does a Phase 1 ESA Cost?

Phase 1 Environmental Site Assessments cost anywhere between $1,800 to $4,600. The cost is dependent upon property location, and the complexity of the site’s history and uses.

A Phase I environmental site assessment can confirm suspicions about whether or not a property has potential risks, but it acts as only a single layer of a complete assessment process. It does not include collection or evaluation of soil samples, water, lithological analysis, radon testing, or any other kind of lab analysis. The study can determine whether a Phase 2 ESA needs to be conducted, or it can confirm that a site is indeed “clean” so that the sale of the land may proceed.
