Key Contract Provisions Every Massachusetts Contractor and Project Owner Needs

By a Massachusetts Business Attorney  · Construction Law

“Why does it matter what’s in my construction contract?” The answer is simple. Because when something goes wrong on a job, your contract is the only thing standing between you and a financial disaster. Most contractors and project owners sign construction contracts without really understanding what they’re agreeing to, and that’s when I get the call.

Let me walk you through the provisions that matter most in Massachusetts construction work. These aren’t just legal technicalities. They’re the safeguards that protect your money, your timeline, and your business.

Scope of Work: Be Specific, or Pay for It

The single biggest source of construction disputes I see is an unclear scope of work. You think you’re agreeing to build a deck. The owner thinks that includes the stairs, the railing, and the stain. Nobody agrees on what “finished” means until the job is half done.

Here’s what I tell clients: your scope of work needs to be detailed enough that someone who wasn’t there could read it and know exactly what’s being built or repaired. Include:

1. Detailed description of the work, including materials and finishes
2. Specific locations and dimensions
3. Plans, drawings, or specifications that are incorporated into the contract
4. What is explicitly NOT included (exclusions matter as much as inclusions)
5. Any existing conditions or assumptions about the property

Massachusetts courts, like courts elsewhere, interpret contracts against the drafter. If you’re a contractor and you drafted a vague scope, the owner’s interpretation will likely win. If you’re an owner and your contractor drafted something unclear, you’ll both end up fighting about what you paid for. That’s why clarity at the start saves litigation later.

Payment Terms and Schedule: Protect Your Cash Flow

This is where contractors lose money month after month. Your contract needs to specify:

1. The total contract price and what it includes
2. How and when progress payments are made (weekly, monthly, upon completion of phases)
3. The amount or percentage of retainage (money held back until final completion)
4. When retainage is released (at final completion, 30 days after, etc.)
5. Interest due if payment is late
6. What triggers final payment and what constitutes “substantial completion”

For residential construction in Massachusetts, M.G.L. c. 142A, § 3 has specific requirements around contract timing and disclosures. Your contract should comply with those requirements, but more importantly, it should be clear about when you get paid. I’ve seen contractors complete work and wait six months for the final payment because the contract didn’t clearly define when the owner’s payment obligation arose.

On the owner side, you want to make sure your contract protects retainage as leverage for corrections and punch list items. Don’t give up that leverage too early. That retainage is your insurance that the contractor will come back and finish what needs finishing.

Change Order Procedures: Your Protection Against Scope Creep

Here’s something I see contractors get wrong all the time: they do extra work based on a phone call or a verbal okay from the owner. Weeks later, when the final bill comes due, the owner says “that wasn’t authorized” or “I never agreed to that price.” Now you’re left proving what you were owed, and the owner is left thinking you’re trying to pad the bill.

Your contract must include a change order procedure. It should say:

1. All changes to the scope of work must be documented in writing and signed by both parties
2. The change order must specify the additional work, the cost, and any time extension
3. No work beyond the original scope will be performed without a written change order
4. The contractor will not proceed with extra work until the change order is actually signed

I recommend that contractors add language stating they won’t start extra work until the change order is signed, not just “agreed to.” This protects you from doing work and having to prove later what you were owed. It also protects the owner from unexpected billing.

Owners should make sure the change order procedure gives you a way to get items in writing. If your contractor is resistant to putting things in writing, that’s a red flag. A reputable contractor wants documentation as much as you do.

Dispute Resolution and Indemnification: Know Where You Stand

Most construction contracts include two critical but often misunderstood provisions: dispute resolution and indemnification.

Dispute resolution means how you’ll handle disagreements if they arise. Your options include:

1. Negotiation between the parties
2. Mediation (a neutral third party helps you reach agreement)
3. Arbitration (a private decision-maker hears the case and makes a binding decision)
4. Litigation (court)

Each has pros and cons in terms of cost, speed, and confidentiality. Some contractors prefer arbitration because it’s faster and private. Some owners prefer litigation because they want a court record if things go bad. Make sure your contract is clear about which process applies, and understand what you’re signing up for.

Indemnification is trickier and more important than most people realize. When you indemnify someone, you’re agreeing to cover their losses if things go wrong. In construction, owners often demand that contractors indemnify them for injuries on the job site. That makes some sense, but I’ve seen contracts where the contractor indemnifies the owner even if the owner’s own negligence caused the injury. That’s where you need to push back. Look for language that limits your indemnity to losses caused by your own acts or omissions, not the owner’s or a third party’s.

Massachusetts courts will enforce indemnification clauses, but they interpret them fairly narrowly. Still, you don’t want to sign away more liability than necessary. Don’t agree to indemnify someone for their own negligence. That’s unreasonable and uninsurable.

Termination Rights and Warranty Provisions

Your contract should clearly specify what happens if either side wants out of the deal:

1. Can the owner terminate for convenience (just because they’ve changed their mind)?
2. If so, what does the contractor get paid (cost plus profit, cost only, a percentage)?
3. Can the contractor terminate if the owner doesn’t pay or breaches the contract?
4. What notice is required?
5. What happens to the work in progress and materials on site?

I’ve seen contracts that don’t address termination at all. When an owner gets cold feet mid-project, nobody knows what they owe. Is it just the work done so far? What about the contractor’s overhead and profit? Clarify this upfront.

Warranties are equally important. Your contract should specify:

1. The duration of any warranty on the work (one year, five years, ten years)
2. What’s covered (workmanship only, or materials too?)
3. Who’s responsible for warranty repairs (the original contractor, a subcontractor, a supplier)
4. The process for making a warranty claim and how the contractor gets notice

For residential work, Massachusetts law sets certain minimums under M.G.L. c. 142A, but your contract can be more or less protective depending on your negotiating position. Owners should make sure they know what they’re getting and for how long. Contractors should be clear about what you’re warranting so you’re not liable for problems that arise from normal wear and tear or owner misuse.

The Bottom Line

I’ve handled too many construction disputes where one party says “but I thought the contract meant this” or “I didn’t realize that wasn’t included.” The difference between a job that goes smoothly and one that ends up in litigation often comes down to whether the contract was clear from the start.

Whether you’re a contractor protecting your right to payment or an owner making sure you know what you’re buying, take the time to negotiate and understand every major provision. Don’t sign a contract just because you’re eager to get started. A few hours of clarity on the front end saves months of fighting later.

If you’ve already signed a contract and you’re concerned about what it says, or if you’re about to sign one and want to make sure you’re protected, I can help.
