What Should You Ask Before Signing a Custom Home Contract?
A custom home contract is a 12 to 24-month commitment worth $400,000 to over $1,000,000. These questions identify the builders who will manage your project with accountability.
How Do You Price and Manage Change Orders?
Ask for a specific walkthrough of the change order process: ‘If I decide to upgrade the kitchen countertop after the contract is signed, walk me through exactly what happens.’ The answer should include: the builder produces a written description of the change, a detailed price breakdown (labor, material, markup percentage, and any schedule impact), and requires your written approval before any work on the change begins. A builder who says changes can be discussed on-site and invoiced later is describing a process that creates billing disputes. A builder who cannot answer this question with a specific process has not systematized change order management.
Who Manages My Project Day-to-Day?
Ask: ‘Who is my primary contact for this project, and who is the site supervisor?’ Many custom home builders are principals who personally manage projects — and then grow their business to the point where the principal is rarely on-site. Ask specifically whether the person you are meeting with will be your daily contact or whether you will be handed off to a project manager. Meet the project manager and site supervisor before signing — these are the people who will actually manage your home’s construction.

How Do You Manage the Draw Process?
Ask: ‘Walk me through how draws are requested, how quickly inspections are scheduled, and how quickly funds are disbursed.’ A builder with an organized draw process submits draw requests promptly after milestone completion, works with an efficient lender who schedules inspections quickly, and has a track record of draws being disbursed within 5 to 10 business days of request. A builder whose draw management is disorganized creates cash flow stress for subcontractors — which translates to slower work and subcontractor disputes during construction.
What Is the Warranty After Completion?
Ask: ‘What specific warranty do you provide on the completed home, and what does it cover?’ Quality custom builders provide: 1-year workmanship warranty (all defects in labor and materials), 2-year mechanical systems warranty (plumbing, electrical, HVAC), and 10-year structural warranty (foundation, framing, structural defects). These are industry-standard terms under the Residential Construction Performance Guidelines (RCPG) published by the NAHB. A builder who cannot describe their warranty terms specifically has not formalized their warranty process. (For more on this, see How to Find the Best Custom Home Builder.)
Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
Making a Confident Decision
The information in this article is designed to help you ask better questions of the professionals you work with, evaluate their answers with more confidence, and understand the decisions involved in this type of home services project. It is not a substitute for professional assessment of your specific home. (For more on this, see Questions to Ask a Custom Home Builder.)
Every home is different. Roof slopes, local weather, tree exposure, soil conditions, and existing system condition all affect what the right solution is for your specific situation. The general principles here apply broadly, but a professional who assesses your home in person will give you guidance that accounts for the details that general articles cannot.
When you are ready to move forward, getting at least two or three quotes from licensed, insured, local contractors is the most important practical step. It lets you compare approaches, assess contractor quality, and confirm that the solution proposed matches your specific situation and budget. The FTC advises hiring only licensed, insured contractors, getting the full scope in writing, and never paying the full amount up front.
