Who is liable when a build-out runs late?

Key facts

Why is delay liability so hard to pin down?

Because a dental build-out usually runs under two contracts that weren't written together. The lease governs the landlord's work and your rent start date. The construction contract governs your general contractor. Holland & Knight warns that if the landlord's construction contract allows broader time extensions or a different substantial-completion trigger than the lease, the two can fall out of step (Holland & Knight). The same mismatch can hit you between your lease and your own contractor.

Delays also come from many hands at once: permits, utility service, equipment lead times, inspections and late design changes. See common build-out delays for causes.

When the landlord is late

If the landlord is delivering the shell or doing work before you take possession, your protection is whatever the lease says. Holland & Knight's June 2026 analysis recommends:

• An outside date for landlord work tied to an extension of the rent commencement date. Rent tolling alone "rarely solves the business problem" (Holland & Knight).
• Liquidated damages that commonly accrue daily after the deadline. Landlords often prefer to pay them as future rent abatement (Holland & Knight).
• A self-help right to finish landlord work at the landlord's cost, backed by coordinated lease and construction contract terms (Holland & Knight).
• Remedies that run until substantial completion, defined as the work needed for lawful occupancy and operational launch (Holland & Knight).
• Narrow force majeure: events outside the landlord's control, promptly noticed, subject to mitigation, possibly excluding routine permitting issues (Holland & Knight).

Put these in the lease before you sign; see the dental lease negotiation checklist.

When the contractor is late

Under A201-2017, the contract time is "of the essence" and the contractor confirms by signing that it is a reasonable period (§8.2.1) (AIA A201-2017 sample). But that alone doesn't give you money. A201 §15.1.7 is a mutual waiver of consequential damages; on the owner's side it covers rental expenses, losses of use, income, profit, financing and reputation (AIA Contract Documents). For a dental practice, lost production during a late opening is exactly that kind of loss.

The fix is liquidated damages. The waiver doesn't preclude an award of liquidated direct damages when they are provided in the contract documents (AIA Contract Documents). Set a daily amount you can justify, such as your daily debt service and rent. Holland & Knight's advice from the lease context applies here too: state that actual damages are hard to quantify at signing and that the amount is a reasonable estimate, not a penalty (Holland & Knight). Dental & Medical Counsel likewise lists "milestones with penalties for delay" among the terms to negotiate (Dental & Medical Counsel).

When the delay is excusable

Section 8.3.1 of A201-2017 extends the contract time for delays caused by the owner or architect, changes ordered in the work, labor disputes, fire, unusual delay in deliveries, unavoidable casualties, adverse weather, and other causes beyond the contractor's control (RIW). An extension means no liquidated damages for that period.

Whether the contractor also gets paid for its delay costs is a separate question. RIW notes that §8.3.3 doesn't bar recovery of delay costs but doesn't mandate them either; owners often add "no damage for delay" language making a time extension the only remedy (RIW).

When the tenant caused it

You are the owner on your own build-out, so your delays count against you. Late equipment selections, design changes after permit, and IT or equipment vendors who aren't ready on time all show up as owner-caused delay. Landlords also negotiate tenant-delay clauses; Holland & Knight says those should be administered with discipline, with clear notice (Holland & Knight). Lock equipment and technology decisions before permit drawings, and involve IT early.

How do I protect myself before it happens?

1. Align dates: lease outside date, rent commencement, contract substantial completion and your loan's draw schedule.
2. Define substantial completion the same way in both documents: lawful occupancy and patients in chairs (AIA A201-2017 sample).
3. Add liquidated damages to both documents.
4. Put every change in a signed change order with its time impact.
5. Keep a dated log of notices, inspections and decisions; Holland & Knight advises keeping excuse provisions narrow and notice requirements tight (Holland & Knight).
6. Build float into the plan; see the build-out timeline.

Which free tools help with this?

The permit & inspection tracker (free tool, coming soon) is planned to track permits, inspections and the certificate of occupancy in one place. 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. 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).

How FloorStack helps

FloorStack is a dental build-out platform that gives the doctor a dated record of the project. The free Permit & inspection tracker (coming soon) will log permits, inspections and the CO against your deadlines, which is the record you need if a delay turns into a claim. The free Build-out cost & timeline calculator (coming soon) helps you set a realistic schedule and a daily cost of delay for liquidated damages. Studio (live, free to start) locks the technology scope on the floor plan early, so IT and equipment don't become the owner-caused delay (FloorStack).
