Three Site Selection Mistakes That Will Cost You More Than Your Build

A site that looks right can be completely wrong. This is one of the most expensive lessons in commercial development, and it gets learned over and over because the mistakes aren't visible to the untrained eye. The property looks suitable. The location feels right. The price seems fair. Then due diligence reveals a problem that either kills the deal after money has been spent, or worse — the problem surfaces after the contract is signed and the entitlement process has already started. By then, backing out is its own kind of expensive. Moving forward is more expensive. There's no clean exit.

Three scenarios account for a disproportionate share of site selection disasters in the healthcare and specialty commercial world. Each one is preventable with proper due diligence. Each one has ended projects or added six-figure costs that no one budgeted for.

The zoning problem that isn't obvious at first is the most common. A parcel is zoned commercial. The listing describes it as suitable for medical or retail use. Everything about the zoning designation on paper looks compatible with a dental clinic, veterinary office, or healthcare practice. The due diligence checklist gets ticked off, the contract gets signed, and then someone actually reads the zoning code in detail. Certain commercial zones permit healthcare uses, but not as a matter of right — they require a conditional use permit. A conditional use permit isn't a formality. It's a discretionary approval process that typically involves a public hearing, sometimes multiple hearings, notice to adjacent property owners, and a period in which neighbors or advocacy groups can object to the project.

That's what happened to one practice owner who found what seemed like a perfect corner lot in a strong demographic area. Zoned commercial, traffic count was excellent, demographics were exactly right, good visibility. The price was fair. The deal was signed. Three weeks into the process, the land use attorney flagged that the specific subzone required a conditional use permit for healthcare occupancy. The public hearing was eight months away on the planning commission calendar. There was potential opposition from adjacent residents. By the time the conditional use permit was granted — nearly a year after the contract was executed — the owner had spent money on legal fees, planning consultants, and lost time that couldn't be recovered. A site that looked like a six-month project became an eighteen-month one before construction started.

The fix is simple and costs almost nothing: before a contract is executed, confirm with the local planning department — not just the listing broker — that the intended use is permitted by right or by administrative permit, not by discretionary approval. That one phone call, made before any money changes hands, would have avoided the problem entirely.

The utilities problem is invisible until someone checks. A site in an established commercial corridor, on a road with utilities, with neighboring buildings that obviously have city sewer — it seems safe to assume utility connections are available. For most sites, that assumption holds. But "city sewer runs along the road" and "city sewer is accessible from this parcel" are not the same thing. Sewer mains run on specific alignments, and the connection point from a given parcel to the nearest accessible main can involve meaningful distance, easement negotiation, and contractor cost.

One site that looked ideal for a medical clinic checked every box on the initial pass — visibility, zoning, price, traffic. The feasibility study flagged that city sewer ran along the main road, which was accurate. What the initial study missed was that the connection from this particular parcel to the nearest manhole required 800 feet of off-site sewer extension through a portion of the right-of-way that hadn't been fully improved. The engineering estimate came in at $180,000. That number wasn't in anyone's budget. It wasn't in the site cost. It wasn't in the construction allowance. It was a surprise that appeared after the contract was signed and the due diligence period was nearly expired. The project survived, but it survived at a cost that meaningfully changed the return economics. A thorough site feasibility — one that actually traces utilities to the parcel, not just to the general vicinity — would have surfaced this number early enough to negotiate it into the purchase price or walk away cleanly.

The traffic and access problem is one that owners systematically underweight because they're thinking about the site from the car they drove there in, not from the car their patients will drive. Great visibility on a high-traffic road is an asset. But visibility and access are different things. A site can be extremely visible and extremely difficult to enter and exit safely, and those two facts can coexist on the same corner.

One clinic evaluated a site on a busy commercial arterial with strong demographics and excellent signage exposure. Patient volumes were there. The brand would be seen by thousands of drivers daily. The access configuration, however, was a problem that didn't reveal itself until a traffic engineer looked at it: the only driveway was shared with the adjacent tenant, oriented in a way that required patients to make an unprotected left turn across four lanes of fast-moving traffic. The sight lines from that left turn were impaired by a parked truck zone that was in permanent use by a neighboring business. The city traffic department had already flagged the intersection in a prior study and would not approve a new access permit for medical use without mitigation improvements. The mitigation was a signalized intersection — a cost in the hundreds of thousands of dollars that required coordination with the city, adjacent property owners, and the state DOT for the signal timing network. The project was ultimately abandoned at that site.

A traffic analysis conducted before executing the purchase contract — looking specifically at access, not just volume — would have identified this before any money was spent on legal fees, design fees, or the option payment.

These three scenarios aren't exotic. They happen regularly on projects where the site looked right to the owner without looking right to someone who knew what to look for. Proper site due diligence isn't a long or expensive process — it's a structured checklist executed by people who know which questions to ask. Zoning confirmed by the planning department, not the broker. Utilities traced to the parcel, not to the corridor. Access evaluated by someone who understands driveway permits and traffic circulation, not just someone who drove the route.

The site is the foundation of everything that follows. Getting it right before the contract is signed costs very little. Getting it wrong after costs everything.
