A practice-transition buyer will read every chart, model three years of collections, and count every chair. Then they sign for a building they never evaluated. The equipment gets an appraisal. The revenue gets a quality-of-earnings review. The physical plant that has to support both gets a walkthrough and a handshake.
That gap is where the expensive surprises live. When you buy an existing dental or medical practice, you are not just buying a patient base and a set of operatories. You are buying the HVAC that ventilates them, the panel that powers them, the vacuum and compressed-air lines that run them, and whatever deferred maintenance the prior owner deferred. None of that shows up in a chart audit.
The building is the part of the deal nobody underwrites
Practice-transition due diligence is mature on the financial side. Buyers have brokers, lenders, and accountants pushing them to verify collections, insurance mix, and equipment value. What they rarely have is anyone asking whether the space can support the practice they intend to run. The building is treated as a fixed backdrop, not as a set of aging systems with real remaining-life questions.
This is different from a post-close reserve baseline, which sets your multi-year capital plan once you already own the practice. A post-acquisition reserve baseline answers "what should I budget over the next five years." A pre-close review answers a sharper question: "given what this building needs, is the price still right." Same systems, but the timing changes everything about how the answer gets used.
The facility questions that belong in diligence
Ventilation for the operatories. Clinical spaces have air-change and pressurization considerations that a standard commercial office HVAC system was never designed to meet. An overview of ASHRAE 170 dental operatory ventilation lays out the design considerations. Whether the installed system actually delivers them is a question for a mechanical specialist to verify; the diligence step is to document the system's observable condition and configuration and flag the gap between what it looks built to do and what the care model needs, so it is on the table before you close.
Plumbing, vacuum, and compressed air. Dental infrastructure includes systems a general contractor does not touch in a typical office: the vacuum system, the compressed-air supply, and the waste plumbing. A review documents their observable condition and flags visible signs of wear or age; confirming remaining service life on a specific unit is a specialist's call. The point is that a tired vacuum pump does not land as a surprise in your first quarter of ownership.
Electrical capacity. If you plan to add imaging, a CBCT unit, or additional operatories, the existing panel may not have the capacity, and upgrading service is not trivial. Reading available capacity against your expansion plan is a licensed electrician's scope; the diligence step is to document the visible condition of the panels and service and flag the capacity question early, so it becomes a known line item instead of a post-close scramble.
OSHA-relevant facility items and accessibility. Eyewash access, exit paths, and similar facility items are easy to overlook when the focus is clinical. ADA and accessibility at the entrance, the restroom, and the treatment areas carry their own exposure. A review of OSHA-relevant dental office facility requirements gives a buyer a documented picture rather than a blind spot.
What an owner-side FCA is, and what it is not
A Facility Condition Assessment scoped for a practice acquisition is owner-side and buyer-side. It is built around the questions a buyer needs answered, and it documents the observed condition of building systems and any deferred-maintenance backlog. It is not a lender-ordered report. It is not an appraisal or a valuation opinion. It does not set the price or contest it. It documents what is there so the buyer can decide with the building in view.
An FCA increases the likelihood that condition issues are identified before they force the issue after close. It is a baseline and a recommendation. It documents findings; it does not certify condition or promise the absence of issues that a visual and functional review would not surface. The value is in reducing exposure to the surprises that show up as unplanned capital in year one.
How buyers use the record
A documented deferred-maintenance backlog gives a buyer a factual basis to act. That might mean reassessing the offer, negotiating a repair allowance, or simply walking into ownership with a funded plan for the first year of capital spend. The assessment does not negotiate; it grounds the negotiation in what the building actually needs. For buyers assembling several locations, the same discipline scales, and a fractional facilities manager for multi-site dental and medical portfolios keeps the condition record consistent across every deal.
The financial diligence tells you whether the practice makes money. The facility review tells you whether the building it runs in is going to cost you more than the deal assumes. Both belong in the file before you sign.
