Why a Phase I Environmental Assessment Is Critical When Buying a Property for Your Dental Practice

Jordan Uditsky • March 4, 2026

What Lies Beneath

You’re a dental practice owner in search of a new location for your growing enterprise. You’ve decided to purchase rather than lease your new space and have identified an attractive free-standing building that fits the bill. Undoubtedly, you (and likely a professional inspector you retain) will give that structure a thorough once-over to ensure it is suitable and that there are no significant problems that need to be addressed.

 

But that building wasn’t erected in a vacuum – it was built on a piece of land. If your pre-closing due diligence doesn’t include an equally rigorous inspection of that land and, more importantly, what lies below its surface, you could be purchasing a ticking time bomb of environmental liability and remediation obligations.

 

That is why most lenders require buyers of commercial property to conduct a Phase I environmental site assessment (ESA) before they will agree to finance the purchase. Even though such an assessment is not required by law, lenders understand the risks involved if contamination or other environmental hazards are later found to be present. And those risks and accompanying exposure can fall squarely on you and your dental practice, even though you had no role in contaminating the property.

 

However, a Phase I ESA is not only about protecting a lender’s interests, but it also serves as a critical legal and financial protection tool for property purchasers and owners. If you are on the market for a new professional home for your dental practice, here's what you need to know about Phase I ESAs, whether you need one, when to get it, and how the process works.

 

Why a Phase I ESA Matters

 

Phase I ESAs exist because of the environmental contamination legal framework established under the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund. CERCLA imposes strict, joint, and several liability on "potentially responsible parties" for the cost of cleaning up contaminated properties. As noted, that liability can attach to current owners of contaminated land even if they had nothing to do with creating the contamination.

 

However, amendments to CERCLA in 2002 provide protection and a safe harbor from liability for certain purchasers and owners. The "innocent landowner" or "bona fide prospective purchaser" (BFPP) defense can serve as a shield against liability if a buyer has conducted "all appropriate inquiries" (AAI) into the property's prior uses before closing. A properly conducted Phase I ESA satisfies this AAI requirement. Skip it, and you could be on the hook for cleanup costs that run into the hundreds of thousands — or millions — of dollars, even for contamination left behind by a tenant or prior owner decades ago. And good luck seeking indemnification from a long-gone or judgment-proof seller or former owner.

 

Many states, including Illinois, have their own environmental cleanup regimes, but federal CERCLA liability is the primary driver behind Phase I requirements in commercial transactions.

 

When to Order a Phase I ESA

 

Timing matters. A Phase I ESA must be completed within 180 days before the closing date to satisfy the ASTM E1527-21 standard and the federal AAI rule. However, certain components, such as interviews with government officials and a review of government databases, must be completed within one year of closing. If your Phase I is more than 180 days old at the time you close, it will need to be updated or a new one commissioned.

 

Accordingly, it is a good idea to order your Phase I ESA early in the due diligence period, not as an afterthought in the final week before closing. If the assessment identifies a Recognized Environmental Condition (REC), a finding that suggests possible contamination, you'll want time to negotiate with the seller, commission a Phase II investigation (which involves actual soil and groundwater sampling), or potentially walk away from the deal. Rushing that process is a costly mistake.

 

How the Process Works

 

A Phase I ESA is conducted by a qualified environmental professional — typically a licensed engineer or geologist with appropriate credentials. The assessment involves four core components:

 

  • Records review (federal and state databases, historical maps, aerial photographs, etc.)
  • Site reconnaissance (a physical inspection of the property and adjoining properties)
  • Interviews with current owners, occupants, and local government officials; and
  • Preparation of a written report.

 

The process typically takes two to four weeks and costs anywhere from $1,500 to $5,000 or more for a standard commercial property, depending on size and complexity.

 

Environmental concerns may not immediately rise to the surface when you are looking to purchase property for your practice, but a Phase I ESA and the guidance of an experienced commercial real estate attorney throughout the process can help ensure that problems don’t bubble up later that could put you in a legal and financial mess.

As all dental practice owners know, insurance companies frequently make adjustments to their reimbursement amounts, leading to the common circumstance that a patient who paid a certain amount at the time of treatment may be entitled to a credit from the practice. That credit, usually kept on the practice’s books so that the patient can apply it to future services, has two distinct qualities that have significant legal and financial implications when a practice is about to be purchased or sold. Failure to account for and address such outstanding patient credits early in a transaction can lead to unwanted surprises as well as potentially costly penalties. That is because a patient credit is not only a liability on the books of the practice, it is also the as-yet unclaimed personal property of the patient. That latter characteristic comes with legal obligations under state unclaimed property laws. If you are buying or selling a dental practice, here is what you need to know about handling patient credits during and after the transaction. Are you interested in speaking with one of our attorneys? Click here to contact us now. Accounting For Credits in the Purchase Price More often than not, unused patient credits remain just that – unused. If a practice purchaser knew for an absolute certainty that the patient would never return and ask for the credit to be applied to new services, it would not impact the underlying practice valuation or sale price. Of course, nothing is certain, and if a practice has thousands, tens of thousands, or hundreds of thousands of credits on the books, even a fraction of those credits, if redeemed, could have a significant impact on the practice’s profitability. That is why any patient credits should be disclosed, identified, and addressed as early in the transaction as possible so that neither the buyer nor seller find themselves in the uncomfortable position of renegotiating the purchase price or providing the buyer with a credit. Reporting and Accounting Obligations Under Unclaimed Property Laws Any business holding goods or funds that belong to a customer, client, or other company or individual cannot simply pocket that property or money because its owner may have forgotten about it or is unaware of its existence. If a business holding such property, which includes patient credits, loses contact with the owner for a certain period set by law (called the “dormancy period”), the company effectively becomes the trustee of that property, holding it for the benefit of the owner until they make a claim for its return. In Illinois, that claim may come after the owner searches the Illinois State Treasurer’s unclaimed property database . The information in that database comes from businesses that must provide the Treasurer’s Office with detailed and frequent reports about any unclaimed property they hold pursuant to the requirements of Illinois’ Revised Uniform Unclaimed Property Act (the “Act”). Most U.S. states have adopted this model act, so the following discussion of Illinois’ version is representative of unclaimed property laws generally. When Does Property Become “Unclaimed”? As noted, property is considered unclaimed and abandoned if it has not had any activity within a designated “dormancy period” and the holder is unable to locate the property owner. Under Sec. 15-201 of the Act, the dormancy period is three years for most types of property, though others have longer or shorter periods. For example, there is a 15-year period for traveler's checks, a five-year period for money orders, and a one-year period for payroll checks. Patient credits would fall under the three-year period. Reporting and Notice Obligations For Holders of Unclaimed Property Any for-profit and not-for-profit business entities that conduct business in Illinois are required to electronically report unclaimed property to the Treasurer’s Office on an annual basis. Even businesses not holding any unclaimed property must file a negative report advising as such if they meet any of the following criteria: Annual sales of more than $1,000,000; Securities that are publicly traded; A net worth of more than $10,000,000; or More than 100 employees. The deadline for Illinois dental practices to file unclaimed property reports for unused patient credits is May 1 of each year. The report should reflect one year of account activity three years prior to the last calendar year. Example: If your report is due May 1, 2018, your report will cover activity from January 1, 2014, through December 31, 2014. The detailed requirements as to what must be included in the report are set forth in Section 760.410 of the Illinois Administrative Code . At the same time the report is filed, unclaimed property must be remitted to the Treasurer’s Office. Holders of unclaimed property also must make efforts to reach out to the owner before filing their report and remitting the property. Specifically, the holder of property presumed abandoned shall send a due diligence notice to the apparent owner by first-class U.S. Mail between 60 days and one year before reporting the property. The required contents of the due diligence notice are set forth in Section 760.460 of the Illinois Administrative Code . Consequences of Non-Compliance Holders of unclaimed property face significant penalties for failing to comply with the reporting, notice, and remittance requirements of the Act. Interest and penalties may be imposed on the failure to file, pay, or deliver property by the required due date. Specifically, the state can charge interest at 1% per month on the value of the unreported/unpaid property and impose a penalty of $200 per day up to a maximum of $5,000 until the date a report is filed or the unclaimed property is paid or delivered. For businesses that may have neglected their obligations under the Act, Illinois (and most other states that have adopted the uniform act) offers a Voluntary Disclosure Agreement (VDA) program for unclaimed property holders. In exchange for voluntary compliance through an executed VDA, the Treasurer's Office will agree to forgo the right to assess penalties and interest outlined in the Act. How To Address Unclaimed Property Obligations in a Practice Sale As part of transactional due diligence, a practice purchaser should ensure that the seller has satisfied all of its reporting obligations under applicable law. If it has not, the purchaser should require the seller to complete a Voluntary Disclosure Agreement prior to closing and also include a robust indemnification clause in the purchase agreement should the practice later face penalties for noncompliance. Because of the financial complexities and legal risks involved relating to unclaimed patient credits, practice buyers and sellers alike should consult with experienced counsel to help them navigate this significant and oft-neglected aspect of the practice’s finances and operations.
