Most Phase 1 Environmental Site Assessments in Florida fall somewhere between $2,000 and $5,000 for a standard commercial parcel. That’s the honest range, and it’s the range you’ll find published by firms working across the country.
The problem with a range that wide is that it tells you almost nothing. A $2,000 quote and a $5,000 quote can both be for the same ASTM standard on the same size parcel, and one of them can still be the wrong number. What you actually need to know is what moves the price, which parts of a quote are real work and which are padding, and what makes a site in Charlotte or DeSoto County cost more than the same acreage somewhere else.
If you’re not yet sure the report is required in your situation, start with when you actually need a Phase 1 ESA. Otherwise, here’s how a Phase 1 gets priced, and what to look for when the quotes come back.
What You’re Paying For
A Phase 1 Environmental Site Assessment is a records and observation investigation into a property’s environmental history. There’s no drilling and no lab work. If a proposal includes soil samples, that’s a Phase 2, and it should be priced separately.
The fee covers four things:
- The records review. Federal, state, county, and local databases, historical aerial photographs, topographic maps, Sanborn fire insurance maps, city directories, and chain of title. This is where most of the hours go, and it’s where the real findings come from.
- The site reconnaissance. An environmental professional walks the property and documents what’s on it: staining, drums, fill, wells, tanks, transformers, stressed vegetation.
- The interviews. Current and past owners, occupants, neighbors, and local officials.
- The report. A written assessment, prepared to the ASTM E1527-21 standard, identifying any recognized environmental conditions along with the environmental professional’s opinion and a recommendation.
A recognized environmental condition, or REC, is the term the standard uses for the presence or likely presence of a hazardous substance or petroleum product on a property. If you want the full walkthrough of what the report contains and who does what, we covered it in what a Phase 1 ESA actually is, and the shorthand terms are all defined in our engineering glossary.
ASTM E1527-21 is the version EPA recognizes as satisfying All Appropriate Inquiries, the federal due diligence standard that preserves CERCLA liability protections for a buyer. The older E1527-13 standard was retired in February 2024. A cheap report written to a retired standard isn’t cheap, it’s worthless, and that’s the first thing worth checking on any quote.
There’s a second recognized standard worth knowing about if your parcel is rural. EPA also accepts ASTM E2247-23, written specifically for forestland and rural property. On a large tract of former grove, pasture, or timber, that’s frequently the right standard, and a firm that quotes it without being asked is a firm that looked at your parcel before it priced it.
The Five Things That Move the Number
In our experience, almost every quote difference traces back to one of these.
1. Acreage. More ground means more to walk, more to photograph, and more historical coverage to pull. Most firms tier this and the tiers can jump hard: a five-acre parcel is frequently quoted at a third to half again what a one-acre parcel costs.
2. The number of parcels. This is the one people don’t see coming. Each separate parcel ID requires its own chain of title, its own historical research, and its own database radius. Three parcels assembled into one project site is three sets of records, not one. Market adders for this commonly run $500 to $1,000 per additional parcel.
3. How much history the site has. A parcel that’s been vacant scrub since the 1940s is a short review. A parcel that’s been a packing house, then an equipment yard, then a strip retail center is a long one. Every prior use adds records to find, read, and account for in the report.
4. What the prior use was. Certain uses carry known contamination risk and the review goes deeper as a result. Former gas stations and dry cleaners commonly add 30% to 60% to a Phase 1 fee. Industrial history adds 20% to 40%. That’s not a firm padding the invoice, it’s genuinely more work.
5. How fast you need it. Rush work costs money everywhere. A five to seven day turnaround typically carries a $500 to $1,000 premium in the broader market.
What Makes a Southwest Florida Parcel Cost More
The generic cost guides stop at the list above. They can’t tell you what’s specific to this part of the state, and around here there are four conditions that reliably add work. They’re also the four we see turn into environmental surprises on a development project when nobody checks early.
Former grove and pasture land. A great deal of the buildable land in Charlotte, DeSoto, Hendry, and Manatee counties was grove or row crop inside living memory. Pre-1972 arsenic-based pesticides and organochlorines persist in topsoil for decades, and Florida’s soil cleanup target levels under Chapter 62-777, F.A.C. are 2.1 mg/kg of arsenic for residential use and 12 mg/kg for commercial or industrial use. Those are not high numbers. When the 1950s aerials show rows, the historical review gets more careful, not less.
Dip vat counties. Between 1906 and 1962, roughly 3,400 cattle-dipping vats were built across Florida, each one an arsenic bath. Most were abandoned in place with no restoration requirement. The Florida Department of Health keeps a county-by-county count of the ones that are known, and it says plainly that there are likely many more that have not been located. On former pasture, that’s a specific thing to chase through the records rather than a box to check.
Multi-parcel assemblages. Development sites here are frequently stitched together from several platted lots or from odd remnant parcels, particularly in the pre-platted subdivisions. That’s the per-parcel research adder, and it’s the most common reason a Southwest Florida quote comes in above what a buyer expected.
Older commercial corridors. Perchloroethylene from a former dry cleaner migrates through groundwater, so a neighboring property two lots down is still your problem. On any commercial parcel in an established retail corridor, the off-site records review is a real piece of the scope.
What a Low Quote Is Usually Leaving Out
Not every cheap Phase 1 is a bad Phase 1. Some of them are, and they tend to be cheap for the same few reasons.
- A database report instead of a records review. Anyone can order a commercial database package and reformat it. Reading the actual state site file on a nearby facility takes hours, and it’s where the useful findings live.
- A desk review instead of a site visit. The standard requires reconnaissance. Call us old-fashioned, but there’s no substitute for getting our boots dirty on the parcel itself, and a report written from a satellite image is not the same document.
- No interviews. They’re part of the standard and they’re the easiest component to skip quietly.
- A report to a retired standard. E1527-13 has been out since February 2024. It still shows up.
- An environmental professional who doesn’t meet the definition. The standard defines who is qualified to sign. A lender’s counsel will check.
The simple truth is that a Phase 1 is the cheapest look you will ever get at what you’re buying. A few hundred dollars saved on the report is not a good trade against a contamination finding that shows up after closing, when it’s yours.
Who Pays For It
Normally the buyer. The buyer is the party whose CERCLA liability protection depends on the due diligence being completed before purchase, so the buyer is the party with the reason to order it.
It can be negotiated into the purchase contract, and in practice the lender’s requirement often settles the question before anyone has the argument. Occasionally a seller commissions one ahead of listing, which speeds a deal up but raises a reliance question: a report addressed to the seller generally can’t be relied on by the buyer without a reliance letter from the firm that wrote it. Ask about that before you assume you’re covered by somebody else’s report.
If you’re still early enough that the parcel itself is the open question rather than its history, a lot feasibility study is usually the cheaper first look.
Don’t Pay For It Twice
A Phase 1 has a shelf life, and this is where buyers lose money without realizing it.
Under the EPA’s All Appropriate Inquiries rule, the assessment must be conducted or updated within one year before the acquisition date, and certain components, including the interviews, the government records review, the site visit, and the search for environmental cleanup liens, have to be completed within 180 days. A deal that stalls for eighteen months means the report on file no longer does the job it was bought for.
If your closing timeline is uncertain, that’s worth building into when you order. Ordering early feels responsible and sometimes means paying for an update later.
What It Costs If the Report Finds Something
A recognized environmental condition doesn’t end a transaction. It changes the next step, and the next step has its own cost.
That step is usually a Phase 2 Environmental Site Assessment, which is where the sampling happens: soil borings, groundwater monitoring, and lab analysis to find out whether something is actually there and how far it goes. A Phase 2 is a different order of expense than a Phase 1, and the scope depends entirely on what the Phase 1 turned up and how large an area needs to be characterized.
Creek doesn’t perform Phase 2 sampling in-house. We’d rather say that plainly than take the work and figure it out afterward. What we will do is explain what the finding means, give you a realistic picture of the range of outcomes, and put you with a firm that does that work.
Worth knowing: plenty of deals close with a REC identified. The finding gets handled through a price adjustment, an escrow, or further investigation that shows the condition is smaller than the record made it look.
How Long It Takes, and What to Ask For
Creek’s turnaround is one to two weeks. From the day it’s ordered, we can be on the site within a week and have the report to you the week following. Complex sites with a long history or several parcels can run longer, and we’ll tell you that when we scope it rather than when it’s due.
When you ask for a quote, ask for these four things in writing. A firm that can answer them quickly is a firm that has actually looked at your parcel:
- What standard the report is written to. ASTM E1527-21 for a standard commercial parcel, or ASTM E2247-23 if the site is forestland or rural property. Both satisfy All Appropriate Inquiries. Anything else does not.
- Whether a site visit is included, and who performs it.
- How many parcel IDs the quote covers. This is the most common source of a surprise invoice.
- What the turnaround is, measured from the day you order rather than from some later start.
Cost on a Phase 1 depends on the parcel: the acreage, the number of parcels, and how much history the site has. Send us the parcel IDs and we’ll give you a number on your specific site, along with what we already suspect the records are going to show. In this part of Florida we usually have a fair idea before we start.
Working With Creek
Most Phase 1 reports come from a firm you’ll never speak to again. The report arrives, the deal closes, and the relationship ends there.
That’s not how it works when the same firm is doing your geotechnical borings, your civil design, your environmental permitting, and your septic engineering on the same parcel. What the Phase 1 turns up about site history informs the geotechnical work. What the borings find informs the civil design, and the geotechnical report lands on the same desk that already knows the parcel. Nobody has to be brought up to speed twice.
Creek Engineering has spent more than two decades doing this work across Charlotte, Sarasota, Lee, Collier, DeSoto, Manatee, Hendry, and Hillsborough counties. We do the site visit ourselves, we pull the Florida records ourselves, and we’ll tell you honestly when a finding is serious and when it isn’t. The full range is on our environmental engineering services page.
If you have a closing date and need a Phase 1 before it, get in touch with the parcel details and we’ll tell you what the scope looks like.
Frequently asked questions
How much does a Phase 1 ESA cost in Florida?
Most Phase 1 Environmental Site Assessments on a standard commercial parcel fall between $2,000 and $5,000. The number moves with acreage, how many separate parcel IDs are involved, how much prior use history the site has, and whether the property was a known higher-risk use like a gas station or dry cleaner. Simple rural parcels come in lower and complex multi-parcel or industrial sites come in higher.
What makes a Phase 1 ESA more expensive?
Five things, in rough order of impact: total acreage, the number of separate parcels requiring their own research, how many prior uses the site has had, whether any of those uses carried known contamination risk, and how fast you need the report. In Southwest Florida, former grove and pasture land and multi-parcel assemblages are the two that come up most.
Who pays for a Phase 1 ESA, the buyer or the seller?
Normally the buyer, because the buyer is the party whose CERCLA liability protection depends on completing the due diligence before purchase. It can be negotiated into the contract, and the lender’s requirement often settles it first. A seller’s existing report generally can’t be relied on by a buyer without a reliance letter from the firm that prepared it.
How long does a Phase 1 ESA take?
Creek’s turnaround is one to two weeks. From the day it’s ordered we can be on site within a week and deliver the report the week after. Sites with a long history or several parcels can take longer, and we say so when we scope the work.
Does a Phase 1 ESA include soil testing?
No. A Phase 1 is records, observation, and interviews only. Sampling belongs to a Phase 2 Environmental Site Assessment, which is performed only if the Phase 1 identifies a recognized environmental condition worth investigating further. If a Phase 1 quote includes sampling, ask what you’re actually being sold.
How long is a Phase 1 ESA good for?
Under EPA’s All Appropriate Inquiries rule, the assessment has to be conducted or updated within one year before the acquisition date, and certain components within 180 days. A report from a deal that stalled will usually need refreshing before it can be relied on again, which is a real cost on a long timeline.
Which ASTM standard should my Phase 1 ESA follow?
ASTM E1527-21 for a standard commercial parcel. For forestland or rural property, EPA also recognizes ASTM E2247-23, which is often the better fit on large tracts of former grove, pasture, or timber. Both satisfy All Appropriate Inquiries. The retired E1527-13 standard does not, and it still turns up in cheap quotes.
Is a cheap Phase 1 ESA worth it?
Sometimes, and sometimes not. Low quotes tend to be low for identifiable reasons: a database report in place of a real records review, no site visit, no interviews, or a report written to the retired E1527-13 standard. Ask which standard the report follows, whether a site visit is included, and how many parcel IDs the price covers.
