Signing a lease isn't the finish line — it's the starting point.
One of the biggest risks in commercial leasing happens after the lease is signed: when the build-out costs are higher than expected.
Changes in scope, unforeseen conditions, and gaps in pricing or scheduling can cause a build-out to exceed its budget. Cost overruns can affect cash flow, timelines, and operations.
The real question isn't whether risk exists, it's whether you planned for it.
Why Build-Outs Go Over Budget
Even well-planned projects run into issues:
Material price increases
Scope changes during design
Permitting delays
Confusion over landlord vs. tenant responsibilities
Underestimated HVAC, electrical, or mechanical work
Many tenants assume the TI allowance covers everything — until it doesn't.
And when it doesn't, the tenant usually pays.
The Real Cost
Illustrative example: a 10,000 SF build-out budgeted at an assumed $80/SF has an $800,000 budget. An assumed 15% overrun adds $120,000. These inputs illustrate the arithmetic; they are not current market cost benchmarks.
It also creates ripple effects:
Paying rent in two places due to delays
Disruptions to hiring or operations
Cash pulled from growth and redirected to construction
A deal that looked good on paper can change fast.
How Smart Tenants Protect Themselves
The key is simple: you don't manage this risk during construction — you negotiate it upfront. Here's how:
Define the scope clearly. Ambiguity in the work letter is where most surprises originate. Spell out exactly what's included, who's responsible for what, and what "building standard" means in measurable terms.
Define turnkey responsibilities. A turnkey arrangement can place responsibility for a defined scope of work on the landlord. The lease and work letter should specify that scope, delivery standards, approval process, change-order pricing, exclusions, and responsibility for delays. Confirm how tenant-requested changes and unforeseen conditions are handled before relying on a fixed build-out cost.
Build in a project-specific contingency. Agree on the amount with the project team based on the scope, existing conditions, pricing, and identified risks. Keep it separate from the landlord’s allowance.
Protect against delays. Tie your rent commencement to substantial completion of the space, not a fixed calendar date. If the landlord delivers late, you shouldn't be paying rent on a space you can't occupy.
Get competitive bids. Multiple contractor bids expose gaps in pricing and scope early, before they become change orders mid-construction.
The Bigger Picture
Most tenants focus on rent. But build-out risk can be more expensive than the rent itself. The difference between a good deal and a great one often comes down to how risk is handled — not just how the base rate compares.
The Bottom Line
Build-outs rarely go exactly as planned. Smart tenants don't hope for the best — they structure protection from day one, negotiating not just the rent, but the risk.
