Construction Contract Clauses to Watch

The scope of work clause is the spine of the contract. Every other clause references it. A precise scope lists the work to be performed, the materials by brand and tier, the finish quality, and the inclusion or exclusion of related tasks like haul-off, permit pulling, and final cleaning.

Weak scope language is the root cause of most homeowner-contractor disputes. If the scope says install new flooring, the homeowner and the contractor can disagree about whether that includes removing existing flooring, prepping the subfloor, or installing transitions. A complete scope removes that ambiguity.

A fair construction payment schedule ties draws to milestones, not to calendar dates. Common milestones include contract signing, materials delivery, rough-in completion, drywall completion, and final walk-through. Each draw should match the value of work actually completed, not a fixed percentage of the total.

For projects under $25,000, a 10 to 25% deposit is typical, with the balance split across 2 to 3 milestone draws. For larger projects, expect 4 to 6 draws over the project lifetime. Avoid contracts that demand more than 30% upfront, because that imbalances the leverage early in the project.

The change order clause must require a written change order, signed by both sides, before any extra-scope work begins. The change order should describe the additional scope, the new cost, and the impact on the project timeline.

Verbal change orders are the leading cause of project disputes. Even a contractor and homeowner who trust each other forget what was agreed two weeks later. A written paper trail protects both sides. ContractShield generates change orders inside the project workspace and tracks signature status, which removes the manual paperwork problem.

A lien waiver is a written acknowledgment from a subcontractor or supplier that they have been paid for the work covered by a specific draw. Without it, the homeowner can pay the GC in full and still face a mechanic's lien from a sub or supplier the GC failed to pay.

The contract should require a conditional lien waiver tied to each draw the homeowner releases to the GC. The waiver attaches a list of subs and suppliers and confirms each is paid through the draw period. ContractShield collects lien waivers automatically as part of the milestone draw flow.

Most residential construction contracts include a one-year general workmanship warranty plus pass-through manufacturer warranties on equipment and materials. Anything shorter than one year on workmanship is a red flag. Some trades like roofing carry longer manufacturer-specific warranties (Class 4 shingles can carry 30 plus year material warranties), but the labor side stays at the contractor's number.

Review whether the warranty covers parts and labor or parts only. A parts-only warranty leaves the homeowner paying labor for any in-warranty replacement, which can be the larger cost line.

A strong dispute resolution clause names the specific arbitration body (typically the American Arbitration Association or JAMS), the rules under which the arbitration will run (typically AAA Construction Industry Rules), and the venue (the county where the project is located).

Vague language like disputes will be settled by arbitration without naming a body or rules creates ambiguity that delays resolution. Both sides win when the dispute clause is specific.

The termination clause should allow termination for cause (material breach by the other side) and termination for convenience (either side wants out, with a defined wind-down). Termination for cause should require a notice and cure period, usually 7 to 14 days, before termination takes effect. Termination for convenience should specify how the contractor is paid for work-in-progress and how materials on site are handled.

Without termination language, neither side has a clean exit. Most disputes that end up in court started with a vague or missing termination clause.
