What I Look For When I Walk a Building
Before you sign a lease, walk the building with the people who will actually build in it: your GC, your architect, your MEP engineer. A few hours of their time prices what no flyer or tour can: power, mechanical, plumbing, structure, and access. Every finding becomes one of three things — a lease ask, a budget line, or a reason to walk away.
A broker tour and a diligence walk are different events that happen in the same building. The tour is about whether you could see your clinic here: the light, the parking, the neighbors, the address. The walk is about whether this building can physically become your clinic, at a price and on a timeline your pro forma survives. Both matter. Only one of them is usually done before the lease gets signed.
I walk buildings for a living, and the discipline is always the same: bring the right people, check the same systems every time, and determine how everything you find impacts the deal. Here's the version of that discipline you can run on your own next site.
Who should walk the building with you?
Not just you and the broker. The walk works because of who's looking: your architect, who knows your program and can see whether it fits this plate; a GC you trust, who prices what they see out of habit; and a mechanical/electrical/plumbing engineer, because the three most expensive surprises in clinic construction are all in their lane. If the landlord's building engineer will join, take that meeting every time. Nobody knows where the bodies are buried like the person who maintains the building.
This costs something: a few thousand dollars of professional time if these aren't yet your contracted partners, favors called in if they are. Against what it de-risks on a $3–5M build, it is the cheapest insurance in the entire project. The most expensive walks are the ones that don't happen until after you sign the lease.
What do you actually verify on the walk?
The flyer told you the square footage and the rent. The walk verifies the things the flyer rarely mentions:
- Power. Service size, panel capacity, spare breaker positions, and where the meter and switchgear live. Clinics are power-hungry, and an electrical service upgrade is the kind of finding that gets priced in quarters, not weeks.
- Mechanical. Age and tonnage of the existing HVAC units, and who owns their replacement under the lease being discussed. A unit with three winters left is a negotiation item now or your capital expense later.
- Plumbing. Size of the water and sewer lines and where the existing connections are. Healthcare water and sewer demand is exponentially higher than office or retail users, and undersized utilities will create problems down the line.
- Structure and geometry. Column grid against your room module, clear ceiling heights, floor capacity for anything heavy. A grid that yields 14 exam rooms where the flyer math promised 17 is a different business.
- Code and access. Accessible path of travel from parking to suite, restroom count and condition, exit capacity, and anything that smells like a change-of-use trigger. Also the unglamorous list: loading, trash, and where an ambulance would actually pull up.
Take photos of everything, especially panel schedules and equipment nameplates. Half the value of the walk is the argument it settles three months later.
What do you do with what you find?
Findings are only useful if they change the deal. Everything from the walk sorts into three buckets. First, lease asks: conditions the landlord should cure or fund — the aging HVAC unit, the service upgrade, delivery condition language that actually matches the building's reality. These have maximum leverage exactly once, before signing, which is why the walk belongs before the lease. Second, budget lines: things you'll accept and pay for knowingly, priced into scope and contingency instead of discovered during demo. This is how the walk connects to the change-order math: every condition you find standing in the space is one that doesn't arrive later at change-order margins. Third, walk-aways. Which deserves its own section.
When is the answer to walk away?
Some findings aren't discounts. They're deal killers. The utility upgrade whose timeline the utility controls, not you or the landlord, and which moves your opening by two quarters. The column grid that caps your room count below the number your pro forma needs, permanently. The landlord who won't fund or permit infrastructure work on a building that can't function without it. A concession can't fix any of these, because the problem isn't the cost. The building simply can't produce the clinic your model assumes, on the clock your capital allows.
A bad building at a great rent is still a bad building. Rent is maybe 8–10% of a clinic's operating economics. Throughput, opening date, and build cost are the numbers that move the business, and they're set by the physical building far more than by the lease rate. I've walked away from deals that looked great on paper, and every one of them looked better from the next building over.
The discipline that makes walking away possible is writing your thresholds down before you tour anything: minimum room count, latest acceptable opening date, maximum all-in build cost. There are no perfect buildings, only tradeoffs, and thresholds are how you tell an acceptable tradeoff from a fatal one while you're still standing in the space, slightly in love with it, with a broker saying another group is looking at it Thursday. That pressure is real. The thresholds are how you hold against it.
Key takeaways
- A broker tour asks whether you could see your clinic here. A diligence walk asks whether the building can physically become your clinic on budget and on time. Do the second one before the lease.
- Bring the people who will build it: architect, GC, and MEP engineer. Their few hours of time is the cheapest insurance on a $3–5M project.
- Verify the same systems every time: power, mechanical, plumbing, structure and geometry, code and access. Photograph panel schedules and nameplates.
- Sort every finding into a lease ask, a budget line, or a walk-away. Findings that don't change the deal weren't diligence.
- Write your walk-away thresholds (room count, opening date, all-in cost) before you tour. A bad building at a great rent is still a bad building.
Frequently asked questions
When should you do a building walkthrough with your GC and architect?
Before you sign the lease, ideally while the LOI is being negotiated. That's when findings have maximum leverage: the landlord can still cure conditions, fund infrastructure, or adjust delivery language. A walk after signing still helps your budget, but everything it finds has become your problem at your cost.
What does a pre-lease building walkthrough cost?
If your architect, GC, and MEP engineer aren't yet under contract, plan for a few thousand dollars of professional time for a thorough walk of a candidate building. Against a $3–5M build, it's the cheapest de-risking money in the project: a single finding, like an aging HVAC unit shifted to the landlord, typically repays it many times over.
What are the most expensive things to miss on a clinic site walk?
Electrical service capacity, because utility-controlled upgrades run on the utility's timeline; plumbing locations, because fixtures far from existing wet walls mean slab cuts; HVAC age, because replacement is a six-figure question that belongs in the lease; and structural geometry, because a column grid that caps your exam room count changes the business case permanently.
How do you know when to walk away from a clinic site?
Set thresholds before touring: minimum room count, latest acceptable opening date, maximum all-in build cost. Walk away when a finding breaks a threshold in a way no concession cures — a utility timeline nobody controls, a structural grid that can't produce your program, a landlord unwilling to touch essential infrastructure. Price problems are negotiable. Building problems usually aren't.
Touring Buildings This Fall?
I walk candidate buildings with founders and their teams, run the systems check, and sort the findings into lease asks, budget lines, and walk-aways before anything gets signed.
Schedule a ConversationWalk findings become lease asks, and lease asks become clauses. What You're Actually Signing grades 26 of them.
