What Is a Phase 1 Environmental Site Assessment?
A Phase 1 Environmental Site Assessment, written as Phase I ESA in most reports, is a records review and site inspection that looks for signs a property has been contaminated by hazardous substances or petroleum. The consultant follows ASTM Standard E1527-21. Nobody drills or samples anything during a Phase 1.
The work covers historical aerial photos, fire insurance maps, city directories, regulatory database searches, a walk of the property, and interviews with the owner, the occupants, and anyone else who knows the site's history. The report ends with a finding of whether any Recognized Environmental Conditions exist.
Lenders ask for a Phase 1 before they fund a commercial purchase or refinance. SBA 7(a) and 504 loans require environmental due diligence on most real estate collateral. Buyers order one on their own because a Phase 1 completed before closing is what qualifies them for the innocent landowner and bona fide prospective purchaser defenses under CERCLA.
What a Phase 1 ESA Reviews in Michigan
Properties in Detroit, MI fall under Michigan Department of Environment, Great Lakes, and Energy along with the federal databases every Phase 1 covers.
Michigan has a rule that makes the timing of a Phase 1 ESA matter more than almost anywhere else. Under Part 201 of the Natural Resources and Environmental Protection Act, a buyer of a property that qualifies as a facility must complete a Baseline Environmental Assessment within 45 days of purchase or occupancy and submit it to EGLE within six months to avoid liability for the existing contamination. The Baseline Environmental Assessment builds on a Phase 1 and usually needs Phase 2 sampling to document conditions at the time of purchase.
The Michigan lists a consultant checks for a property in Detroit, MI:
- Part 201 Inventory of Facilities. Sites where contamination exceeds residential cleanup criteria, which is the trigger for Baseline Environmental Assessment obligations.
- Part 213 leaking underground storage tank sites. Petroleum release sites regulated under Michigan's tank law.
- Underground storage tank registrations. Registered tanks held by EGLE's Materials Management Division.
- Baseline Environmental Assessment submittals. Prior BEAs filed for the property or neighboring parcels, which reveal earlier findings.
- Brownfield Redevelopment Authority plans. Local authority brownfield plans that show which parcels have received tax increment financing for cleanup.
Common Sources of Contamination on Detroit, MI Properties
The industries that shaped Detroit include automotive manufacturing, steel production, coke processing, metal finishing, chemical production, coal power generation, and auto parts manufacturing. Consultants who work here pay close attention to Delray neighborhood and Zug Island industrial zone, Southwest Detroit and River Rouge corridor, East Side former auto plant district, Hamtramck GM assembly area, Downriver communities including Ecorse and River Rouge, and Detroit Riverfront former industrial waterfront, where past land use raises the odds of a finding.
The auto industry and its suppliers shaped every city from Detroit to Grand Rapids. Stamping plants, foundries, and metal finishing shops left chlorinated solvents, chromium, and petroleum under land that is now being rebuilt. Flint and Saginaw carry the same legacy. Outside the cities the concern turns to agriculture, gravel pits used as dumps, and the state's aggressive posture on PFAS, which has identified hundreds of sites from former plating shops, tanneries, and firefighting foam use. Dry cleaners and gas stations show up on every commercial corridor.

Michigan Cleanup Programs and Buyer Liability Protection
The Baseline Environmental Assessment is the liability tool. A buyer who completes and files it on time takes the property without responsibility for cleaning up what was already there, though the buyer still owes due care obligations under Section 20107a to keep the contamination from getting worse and to protect people on the site. Brownfield Redevelopment Authorities in most counties can approve tax increment financing that reimburses assessment and cleanup costs.
How Much Does a Phase 1 ESA Cost in Detroit, MI?
Across the country a Phase 1 ESA runs from $1,500 to $6,000, and a plain commercial building on a single parcel lands near the low end of that range. A standard Phase 1 in Michigan prices near the national middle. The Baseline Environmental Assessment adds a separate fee, and buyers should budget for both when the property has any industrial history.
What moves the price on a given property:
| Factor | Effect on price |
|---|---|
| Acreage and number of parcels | More ground to walk and more addresses to research |
| Current use | Industrial, automotive, and dry cleaning sites take longer to document |
| Historical use | A former gas station or manufacturing plant means more agency files to pull |
| Turnaround | A rush report in five to ten business days adds a premium |
| Age of the property | Older sites have more historical sources to review |
| Lender scope | Some banks and the SBA add deliverables beyond the ASTM standard |
A quote tied to the actual address is the only way to know the number for your property. Read the Phase 1 ESA cost guide for a closer look at pricing.
Phase 2 Environmental Site Assessment in Detroit, MI
When a Phase 1 finds a Recognized Environmental Condition, the next step is a Phase 2 ESA. A Phase 2 puts soil borings, groundwater monitoring wells, or soil vapor probes in the ground and sends the samples to a lab. The scope depends on what the Phase 1 found, so a Phase 2 in Detroit, MI can cost anywhere from a few thousand dollars for a handful of borings to well above $30,000 for a site with a plume.
The consultants in our network handle both phases. Ask for a Phase 2 quote when you submit your details, or read the Phase 2 ESA guide and the Phase 2 cost guide first.
Phase 1 ESA Questions From Detroit, MI Buyers
How long does a Phase 1 ESA take in Detroit, MI?
A standard Phase 1 ESA typically takes 2-4 weeks from start to delivery of the final report. Rush turnaround options are available, often within 5-10 business days, for an additional fee.
Who needs a Phase 1 Environmental Site Assessment?
Buyers, lenders, developers, and investors involved in commercial real estate transactions. SBA 7(a) and 504 loans typically require environmental due diligence, including a Phase 1 ESA. Banks and lenders typically require one for commercial property financing. It's also recommended when purchasing former industrial or commercial properties.
Do SBA loans require a Phase 1 ESA in Michigan?
SBA 7(a) and 504 loans typically require environmental due diligence for commercial property purchases, which usually includes a Phase 1 ESA. The report must comply with ASTM E1527-21 and be completed by a qualified environmental professional. Requirements can vary based on the property type, historical use, and lender policy.
What ASTM standard governs Phase 1 ESAs?
ASTM E1527-21 is the current standard for Phase 1 Environmental Site Assessments. It replaced E1527-13 and defines the scope, methodology, and reporting requirements. Compliance with this standard is necessary to qualify for the CERCLA innocent landowner defense.
Does a Phase 1 ESA include soil or groundwater testing?
No. A Phase 1 ESA is a non-invasive review of records, regulatory databases, historical sources, and a visual site inspection. It does not include physical sampling. If potential contamination is identified, a Phase 2 ESA with soil borings or groundwater monitoring may be recommended.
What happens if the report finds a Recognized Environmental Condition?
If the Phase 1 ESA identifies recognized environmental conditions (RECs), the next step is typically a Phase 2 ESA, which involves actual sampling and laboratory analysis of soil, groundwater, or air to confirm the presence and extent of contamination.
Can a Phase 1 ESA protect buyers from environmental liability?
Yes. A Phase 1 ESA conducted under ASTM E1527-21 helps establish the "innocent landowner" defense under CERCLA. This can protect buyers from liability for pre-existing contamination they were not aware of at the time of purchase.
What's the difference between Phase 1 and Phase 2 ESAs?
A Phase 1 ESA is a non-invasive investigation that reviews records and inspects the site visually. A Phase 2 ESA involves physical sampling (soil borings, groundwater monitoring wells, etc.) and laboratory analysis. Phase 2 is only needed when Phase 1 identifies potential contamination concerns.
Is a Phase 1 ESA required before buying commercial property in Michigan?
While not legally mandated for all purchases, most lenders, banks, and SBA lenders typically require a Phase 1 ESA before financing commercial real estate in Michigan. It is strongly recommended for any commercial, industrial, or redevelopment transaction to identify potential environmental liabilities.
