Most budget overruns on a buildout don't begin with bad craft. They begin with a contract that leaves something unsaid. Nobody lied; the paperwork was simply silent on the question that later turned into an argument. The good news is that careful tenant improvement contractors expect to put these protections in writing and don't take offense when you ask. Below are five clauses worth looking for before you sign anything, what each should say, and the warning signs that suggest it's missing.
Clause 1: A detailed scope of work, with exclusions
What it should say: Line-by-line explanation of what is included: demolition, walls, doors, finishing, light fixtures, plumbing, HVAC systems, ceiling, painting, and cleanup. Of equal importance is a written description of what is NOT included: furniture, data cabling, signage, window coverings, and permit fees.
Why it matters: Disputes grow in the space between "I assumed that was included" and "that was never priced." A scope that references the approved drawings and specification sheets removes most of that space.
Red flag: Phrases like "per plans" or "standard finishes" with no detail behind them. If the finish level is not named, the price you were quoted may not be the price you pay.
Clause 2: A payment schedule tied to progress
What it should say: A small down payment, followed by milestone payments based on the accomplishment of milestones and not based on a date. For example, down payment upon signing of contract, payment upon approval of rough-in, payment upon completion of drywall, and final payment when certificate of occupancy and punch list are complete.
Also look for a retainage provision, which usually comes up between five and ten percent retained until the project is done and documents are provided.
Why it matters: If you have paid ahead of the work, you lose your ability to say "not yet." Money should trail progress, never lead it.
Red flag: A request for half the contract price upfront. Some deposits are reasonable for ordering materials, but large advance payments shift the risk onto you.
Clause 3: A written change order process
What it should say: Any change in scope requires a written change order signed by both parties, stating the added or reduced cost and the effect on the schedule, before the work is done. It should also state how markups on changes are calculated.
Why it matters: Changes are normal. Walls turn out to hide old conduit, tenants add a room, the landlord asks for a revision. What turns normal into painful is the verbal agreement. A month later, no one remembers what number was discussed.
Red flag: A contract that says nothing about changes, or one that lets the contractor proceed on "time and materials" without a cap or advance approval. Reliable tenant improvement contractors will accept a clear approval step because it protects them from disputes as well.
Clause 4: Start date, completion date and delay terms
What it should say: A specific date when construction can begin after permits have been issued, a specific date of substantial completion, and what will happen if either is not met. Some agreements may specify a sum per day of delay that is not justified. This is usually termed liquidated damages and is based on a fair estimate of your daily losses, such as the rental cost of the unused area.
Why it matters: A completion date with no consequence is a wish. A reasonable delay clause keeps attention on the schedule without being punitive.
Red flag: "Approximately 12 weeks" with no start trigger and no mention of delays. Vague timing usually means vague accountability.
Clause 5: Warranty, insurance and lien protection
What it should say: Written artistry warranty, generally for one year, along with warranty pass-through for manufacturer warranties for equipment and material. Liability insurance, including workers' compensation insurance, is required by the contract, with you and the lessor listed as additional insured if required by the lease agreement, and lien waivers to be obtained from the contractor and significant subcontractors at each payment.
Why it matters: If a subcontractor is not paid, some jurisdictions allow that party to place a lien on the property, which can become your problem even if you paid the general contractor in full. Progressive lien waivers shut that door.
Red flag: Reluctance to provide insurance certificates or waivers. Anyone who hesitates on paperwork this basic deserves a second look.
A few practical habits that back up the clauses
The effectiveness of a contract lies not only in its existence but also in its execution. Store the drawings that have been signed along with the scope of work in one folder. Document all change orders, noting the date and cost. Compare each payment claim against the schedule of values, questioning any unusually high lines.
And lastly, you can afford to get a lawyer to go over the contract, especially if it’s a big deal, just for an hour. It’ll be cheap compared to the money at risk. But more importantly, as you look at different companies, consider their reactions to this. Companies like Hoover GC, for instance, are definitely ones that should make your list if they discuss the terms freely without pushing you to sign.
Final thoughts
Ensuring the safety of a build-out budget comes down to documentation: what’s covered, when payments flow through, how modifications are permitted, when construction ends, and how mistakes will be dealt with.
Ask every single tenant improvement contractor that makes the list for their approach to these five issues, and use that information to make your final choice. Clear contract terms don’t necessarily mean a smooth process, but they sure do make it less likely for a simple mistake to snowball into something major.
FAQs
1. Should a buildout contract be lump sum or cost-plus?
Lump-sum provides certainty in pricing once drawings have been completed. Cost-plus is best for projects where there are unknowns, but requires that there be a guaranteed maximum price and open books. Determine which is appropriate depending on your level of completion.
2. How much retainage is normal?
Between five and ten percent of the payments can be put aside until project completion and punch list completion, as well as issuance of closing documents. The law may have certain regulations regarding retainage and its release. It should be stated in the contract.
3. What is a lien waiver and why ask for it?
A lien waiver is a document whereby a contractor or subcontractor signs off on receiving payment and waives the right to file a lien for that amount. Collecting one with every payment ensures that any unpaid contractors will not file a claim against the rented property or the property owned by the landlord.
4. Can I negotiate a delay penalty?
Usually, yes, but more often than not, where there is an obvious price attached to a late start. This might be acceptable where contractors receive a small amount per day for controllable delay. Ensure that the definition of excusable delay is well drafted.
5. What if the contractor refuses to change the contract?
Do not treat it lightly. Small changes in the language may be acceptable, but an unwillingness to describe the scope, payment arrangements, and changes shows potential for problems ahead. Check out the others, and be prepared to leave. A professional contractor likes clarity.
