Medical Office Lease Costs: $100–$250+/SF Build-Outs, TI Allowances and Terms Explained

The lease is where medical deals are won or lost. The space matters, but the terms — who pays for the build-out, how long you’re committed, what happens to your improvements — decide whether the economics work. Here’s what to negotiate and why.

The TI allowance is the headline number

A tenant improvement (TI) allowance is the landlord’s contribution to your construction, quoted per square foot. On clinical space, where build-outs run $100–250+/SF, the difference between a $50/SF and a $100/SF allowance on a 3,000 SF suite is $150,000 of your capital. Landlords trade TI against rent and term — a longer lease usually buys a bigger allowance. Model the total occupancy cost (rent + your net build-out spend ÷ term), not the sticker rent.

Term length: why medical leases run long

Five to ten years is normal, for both sides’ reasons: you need years to amortize construction, and the landlord needs them to recoup the TI. If you’re not ready for that commitment, second-generation space or a sublease is the honest alternative — shorter terms on already-built space.

Clauses that matter more for medical tenants

• Permitted use: must explicitly cover your practice type — “general office” language is a problem waiting to happen.
• Exclusivity: specialists often negotiate a clause preventing the landlord from leasing to a directly competing practice in the same building.
• Restoration: who un-builds the plumbing at move-out? An unlimited restoration obligation on a clinical fit-out is a five-figure surprise — cap it.
• Ownership of improvements: clarify what stays and what you can take.
• Assignment & sublet rights: your exit path if the practice merges, sells, or outgrows the space.
• Operating hours & services: HVAC after hours, elevator access for patients, waste handling for clinical refuse.

Budgeting the whole project

Beyond rent and build-out: architectural and permit fees, medical equipment and millwork, IT and security, moving and downtime, and the working-capital gap while credentialing and patient flow ramp in the new location. A realistic all-in budget prevents the classic mistake — signing a great lease you can’t afford to finish building.

Negotiate from multiple options

Leverage in a lease negotiation comes from credible alternatives. Touring three viable buildings and letting landlords compete moves TI, free rent, and term flexibility more than any single argument. That’s the core of what a healthcare tenant-rep broker does — and the landlord pays their fee.
