If you are a general contractor working in New Hampshire, having a solid written service agreement is one of the smartest things you can do to protect yourself and your business. A good agreement sets clear expectations with your client, spells out exactly what work you will perform, and helps you avoid the kinds of misunderstandings that lead to payment disputes or lawsuits. This guide walks you through what to include in a general contractor service agreement in New Hampshire and why each piece matters.

Every general contractor service agreement should cover the basics first. That means a clear project scope with start and completion dates, permit and inspection responsibilities, a payment schedule tied to milestones, warranty terms for workmanship, a process for handling change orders. You want anyone reading the document to understand exactly what they are agreeing to. The more specific you are about the scope of work, the less room there is for a client to claim you promised something you did not. If you are managing subcontractors, your agreement should spell out who is responsible for scheduling inspections and obtaining permits so there is no confusion on the job site.

New Hampshire has its own set of rules that affect how contractor agreements work. Depending on the type of work you do and the dollar value of the project, you may need to be licensed or registered with the state, and your license number may need to appear on your contract. If you are not paid for your work, New Hampshire law gives you mechanics lien rights, meaning you can file a claim against the property. You generally have 120 days after you finish work to file your lien, so do not wait. In New Hampshire, clients typically have a three business day right to cancel certain home improvement contracts without penalty. Your agreement should inform the client of this right. New Hampshire also has state energy code compliance for insulation and sealing work. Make sure your agreement accounts for these state-specific requirements. The New Hampshire-compliant template on this page already includes these clauses, so you do not have to figure them out on your own.

Payment terms are where many contractor agreements fall short. Be specific about how and when you get paid. Will you bill a flat fee, an hourly rate, or milestone-based payments? When is the final payment due, and what happens if the client is late? If you are collecting a deposit, check whether New Hampshire limits how much you can collect up front. A clear payment schedule protects your cash flow and gives the client a roadmap of what to expect financially throughout the project.

Finally, think about insurance and liability. Your general contractor service agreement in New Hampshire should address who carries insurance, what types of coverage are in place, and how disputes will be handled if something goes wrong. Carry adequate general liability insurance and workers compensation coverage as required by New Hampshire law. Include a clause stating that you are an independent contractor, not an employee, so there is no confusion about tax responsibilities or employment relationships. A well-written agreement protects both you and your client, and it shows that you run a professional operation.
