5 Contract Clauses Your Contractor Hopes You Never Add

You're about to sign a contractor's agreement and it looks official. Nice logo, clean formatting, a few pages of terms. Feels legit.

It's not protecting you. Not even close.

I've reviewed hundreds of contractor contracts over the years and the pattern is always the same. The document protects the contractor's right to get paid. Your right to get quality work, on time, without surprise charges? Nowhere in the paperwork.

Here are five clauses I tell every homeowner to add before they sign anything.

1. The "Not-to-Exceed" Price Cap

Contractor quotes often say "estimated cost." That word, estimated, is doing heavy lifting. It means the final bill can be higher. Sometimes $2,000 higher. Sometimes $8,000.

Add this language: "Total project cost shall not exceed $[amount] without prior written approval from homeowner."

I had a client last month whose HVAC install came in $4,200 over the quote. The contractor pointed to the word "estimate" and shrugged. If she'd had a not-to-exceed clause, that conversation goes differently.

The contractor will push back. That's fine. A contractor who won't cap their price is telling you something about how they run jobs.

2. The Payment-Milestone Schedule

Never pay more than 10% upfront. I know contractors will ask for 30%, 40%, sometimes half. Don't do it.

Structure payments around completed milestones:

• 10% at signing (materials deposit)
• 30% when materials are delivered and verified on site
• 30% at rough completion (framing done, systems roughed in)
• 20% at substantial completion
• 10% held for 30 days after final walkthrough

That last 10% is your leverage. It's the only thing ensuring the contractor comes back to fix the cabinet door that doesn't close right or the paint touch-up they "forgot."

I put together a free checklist that walks through all of this, clause by clause. Grab it here.

3. The Written Change-Order Requirement

"While we're in here, we noticed your subfloor needs replacing. It'll be another $3,500."

That's the most expensive sentence in home improvement. Mid-job upsells account for $500 to $8,000 in unplanned costs on a typical renovation.

Your clause: "No additional work shall be performed, and no additional charges shall apply, without a signed written change order specifying scope, cost, and timeline impact."

Verbal agreements mid-job are worthless. The contractor says it'll be $1,200. The invoice says $2,800. Without a signed change order, you're arguing your memory against theirs.

4. The Permit and Inspection Guarantee

Skipped permits are one of the most common contractor shortcuts. The work might look fine. But when you sell your house and the buyer's inspector finds unpermitted electrical or plumbing, you're looking at $5,000 to $15,000 to rip it out and redo it to code.

Add: "Contractor shall obtain all required permits prior to work commencement and shall not consider the project complete until all inspections are passed. Permit numbers to be provided to homeowner within 5 business days of issuance."

I check permit status on every project I consult on. About 1 in 4 contractors "forget" to pull them. That number goes to nearly zero when the contract requires it.

5. The Dispute Resolution Clause (That Favors You)

Most contractor contracts include an arbitration clause. Sounds fair. It's not.

Contractor-drafted arbitration clauses typically name the arbitration service, location, and cost-sharing arrangement. All of it favors the contractor. Some even require you to travel to a different county.

Replace it with: "Disputes shall first be addressed through written notice and a 15-day cure period. If unresolved, either party may pursue remedies through [your county] small claims court or [your state] licensing board complaint process."

Small claims court costs $30-$75 to file. Arbitration costs $1,500-$5,000. The contractor knows which one you're more likely to actually use.

The Pattern Here

Every one of these clauses does the same thing. It takes a verbal promise and makes it enforceable. Contractors who do quality work won't blink at any of them. The ones who push back hard are telling you exactly who they are.
