How do I negotiate a dental lease?
On this page
Negotiate before you sign, with a dental-experienced attorney, and focus on the terms that decide whether you can build, open on time and sell later: TI allowance, delivery and rent-commencement dates, exclusive use, relocation, assignment and renewals. Dental lenders usually want at least a 5-year term (Dental Practice Brokers). The 2026 checklist is below.
This page is general information, not legal advice. Have a dental-experienced attorney review any lease before you sign.

Why is a dental lease different from an office lease?
Because you'll put hundreds of thousands of dollars of plumbing, vacuum, electrical, cabinetry and shielding into someone else's building, and you can't easily move it. Mostofi Law Group, a California dental lease firm, calls the office lease most dentists' second-largest financial commitment after the practice itself (Mostofi Law Group). The lease also decides what your practice is worth when you sell: Jaffe Law notes that buyers want 10 or more years remaining when they acquire a practice (Jaffe Law).
The checklist
Money and build-out
- TI allowance sized to a real dental budget, with disbursement timing and what it can pay for. See TI allowance and build-out cost.
- Work letter that assigns landlord work versus tenant work line by line: plumbing stub-outs, electrical capacity, HVAC, ceiling height, slab trenching for vacuum.
- Free rent or abatement during construction.
- CAM and operating expense caps, plus audit rights. Mostofi lists uncapped pass-throughs among dangerous landlord-drafted terms (Mostofi Law Group).
Dates and delays
- Delivery date and outside date. Holland & Knight advises setting an outside date for landlord improvements tied to an extension of rent commencement (Holland & Knight).
- Remedies for late delivery: daily liquidated damages or rent abatement, self-help, and a termination right if delay becomes severe (Holland & Knight).
- Narrow force majeure that excludes routine permitting, supply chain and contractor underperformance (Holland & Knight).
- Rent commencement tied to substantial completion that means lawful occupancy and operation. See build-out delay liability.
Use and competition
- Broad permitted use covering current and future services. A narrow "general dentistry only" clause can block adding orthodontics or oral surgery later (Cohen Law Firm).
- Exclusive use barring other dental practices in the building or center (Jaffe Law).
- Operating hours and after-hours HVAC that fit your schedule.
- Signage rights.
Relocation, demolition and termination
- Relocation clause removed, or limited with 6–12 months' notice and landlord-paid moving and rebuild (Cohen Law Firm).
- Demolition and early-termination clauses removed or compensated (Mostofi Law Group).
Assignment and exit
- Assignment to a qualified dental buyer with consent not unreasonably withheld, conditioned or delayed (Jaffe Law; Cohen Law Firm).
- No landlord share of sale proceeds (Cohen Law Firm).
- No pass-through of landlord's fees on assignment (Dental Practice Brokers).
- Personal guarantee limited, and released on assignment to a qualified buyer (Jaffe Law). Cohen Law Firm describes negotiating caps of 12–24 months of rent and burn-off after 36 months of timely payment (Cohen Law Firm).
- Renewal options at defined terms; a 5-year term with multiple 5-year renewals is one broker's recommendation (Dental Practice Brokers).
- Ownership of improvements at lease end spelled out, including what you may remove. This affects valuation later; see valuing leasehold improvements.
What does a dental lease review cost?
Less than one bad clause. As one published example, Cohen Law Firm lists a flat fee of roughly $2,500–$5,000 for a standard dental lease review and negotiation, and $4,000–$7,500 for build-out leases with substantial tenant improvements (Cohen Law Firm). That's one firm's pricing, not a market rate; get a quote and a scope in writing. Ask whether the fee covers the LOI as well as the lease, because many of the terms above are easiest to win at the LOI stage.
When should I negotiate?
Before you sign the LOI, ideally while you still have a second site in play. Dental Practice Brokers warns that waiting until a sale is imminent is often too late, because your leverage is the threat of leaving at signing or renewal (Dental Practice Brokers). Test-fit the space first so you know it holds your operatory count; see square footage and lease vs. buy.
Which free tools help with this?
The build-out cost & timeline calculator (free tool, coming soon) is planned to estimate build-out cost and timeline from square footage and operatory count. The dream-practice builder (free tool, coming soon) is planned to let you lay out rooms and operatories before anything is drawn. FloorStack Studio (live, free plan) places every device on your floor plan and gives you a device schedule with rooms, ports and cable lengths (FloorStack FAQ).

Frequently asked questions
What's the most important clause in a dental lease?
Many dental attorneys say assignment, because it decides whether you can sell (Cohen Law Firm).
How long should a dental lease be?
One broker recommends a 5-year term with multiple 5-year renewals and notes lenders often require at least 5 years (Dental Practice Brokers).
Can I remove a relocation clause?
Often you can negotiate it out. If not, require long notice and landlord-paid relocation (Cohen Law Firm).
What protects me if the landlord's work is late?
An outside date, rent tolling, liquidated damages or abatement, and a termination right (Holland & Knight).
Should I sign a personal guarantee?
Often lenders and landlords require one. Try to limit it and get it released on assignment (Jaffe Law).
Do I need a dental-specific attorney?
It helps. Dental-specific issues like exclusives by practice type and work-letter specs are easy to miss.
