What Most Dental and Medical Tenants Get Wrong Before Signing a Lease

A dental or medical lease is not a standard office lease.

You are often signing for ten years, investing hundreds of thousands of dollars into specialized improvements, and tying your practice to a location that has to work for patients, staff, providers, equipment, and future growth.

Most of the expensive mistakes I see do not happen at renewal. They happen at signing, when the tenant is focused on the first-year rent and misses the lease terms that drive the real cost over time.

Here are the terms that actually move the numbers.

The expense base year can quietly become one of the biggest costs

In a full-service office lease, you are not just negotiating the starting rental rate. You are also negotiating how operating expenses are handled over time.

Most office leases include a base year or expense stop. The landlord covers operating expenses up to that base amount, and the tenant pays its pro-rata share of increases above it.

That sounds simple, but it can become expensive if the base year does not reset at renewal.

For example, say a dental practice leases 4,000 square feet in a medical office building. The lease is full service, and the tenant's expense base year is set in Year 1. Over the next ten years, taxes, insurance, utilities, repairs, janitorial, management fees, and other building costs increase. By the end of the term, the tenant may already be paying a meaningful amount in pass-through expenses above the original base year.

Now the renewal comes up. If the tenant negotiates a new rental rate but fails to reset the expense base year, they may be renewing into a "new" deal while still paying over a ten-year-old expense base. That can make the effective rent much higher than the face rate in the lease.

This matters because medical and dental practices usually stay in place for a long time. Once you have invested heavily into plumbing, electrical, cabinetry, imaging rooms, sterilization areas, treatment rooms, and specialized equipment, moving is expensive and disruptive. The landlord knows that.

That is why renewal language needs to be negotiated in the original lease, while the tenant still has leverage.

The key issue is not only the starting rental rate. It is whether the renewal includes a reset of the expense base year, a cap on controllable operating expense increases, clear exclusions from pass-throughs, and a fair method for calculating your pro-rata share. Otherwise, the tenant may win a small concession on rent and lose far more over time through operating expense pass-throughs.

Exclusivity protects the procedures your practice depends on

Exclusivity is not just about who leases the space next door. It is about protecting the specific procedures and services that drive your revenue.

For a dental, orthodontic, med spa, surgical, or specialty medical practice, this can be critical. If another tenant in the same building or center is allowed to offer overlapping services, it can directly impact your patient flow and revenue.

As your tenant representative, this is something we can ask to have written into the lease up front. If it is in the lease, you have protection. If another practice tries to come in later and offer the same procedures that drive your business, the clause gives you recourse.

Without it, you may have none.

This is not something you try to fix after the fact. You negotiate it at signing, or you usually do not get it.

The use clause can create problems after you start spending money

This issue is especially important in retail and mixed-use properties.

A landlord may tell you that your use is acceptable, you sign the lease, and you start design and buildout. Then you find out the use also requires approval from the property owner, master landlord, condo association, or an anchor tenant with approval rights.

If that approval does not come, the tenant can be stuck after already spending real money.

I have seen tenants get well into the process before learning that the landlord could not actually get the required approval for the use.

Before you spend money on design, permitting, or construction, make sure the use is confirmed in writing by the right parties.

TI is a lever, not a gift

Tenant improvement dollars are not free money.

The landlord is underwriting those dollars into the overall economics of the deal and expects to recover that investment through rent, term, credit, and total return over the lease.

That is why TI, free rent, base rent, term, escalations, and tenant credit have to be negotiated together, not separately.

Sometimes the right move is to push for more TI and accept a higher rental rate because preserving cash for the practice matters more. Other times, it may make sense for the tenant to fund more of the buildout directly in exchange for a lower rent.

The right answer depends on the tenant's cash position, the cost of the buildout, comparable deals in the market, and how the landlord is viewing risk and return.

This is especially important for medical users. A standard office buildout is one thing. A dental, surgical, or medical suite can require additional plumbing, electrical capacity, medical gas, specialized flooring, equipment infrastructure, and higher construction costs. That makes the TI conversation much more important than it would be for a typical office tenant.

A strong negotiation is not just asking for more money. It is knowing which levers to push, how far to push them, and how to structure the deal so the tenant gets the best economic outcome while still making sense for the landlord.

Know your real buildout costs before you negotiate the TI

You cannot negotiate the right TI number if you do not know what the space will actually cost to build.

Too many tenants accept an allowance that sounds generous, only to find out later that it covers a fraction of the actual medical buildout. By that point, the lease is signed, leverage is gone, and the tenant is forced to absorb the gap.

The better approach is to get a real cost picture early. Understand the likely buildout range, identify the expensive items, and then negotiate the TI, rent, free rent, and term around the actual economics of the project.

The buildout team matters

How the buildout is contracted and managed matters as much as the lease itself.

For healthcare clients, I typically help coordinate with project managers, contractors, architects, and other professionals who understand medical and dental buildouts. The goal is to competitively price the work, manage the process, and avoid leaving the tenant dependent on only one contractor or the landlord's preferred vendor.

That helps protect the tenant on cost, accountability, and execution.

The lease and the buildout should not be treated as separate decisions. They are part of the same economic deal.

The mistake is focusing only on the headline rent

The pattern is usually the same.

The tenant negotiates hard on the rental rate and gives away the terms that actually determine cost and risk over the life of the lease.

For healthcare tenants, the real economics are in the details: expense structure, renewal language, TI, free rent, use approvals, exclusivity, buildout obligations, assignment rights, signage, parking, and operating expense protections.

A tenant rep who works on healthcare leases knows where those terms hide and how to address them while you still have leverage.

That leverage is strongest before you sign.

If you are evaluating a new location, expansion, or renewal in Northern Virginia, Washington, DC, or Maryland, that is the right time to have the conversation.
