Questions to Ask a Builder When Planning a Project

Start a one-page brief with questions to ask a builder

Set up a one-page worksheet with seven headings: desired outcome and constraints; existing information; scope; responsibilities; open questions; change log; handover. Keep facts, assumptions and gaps in separate notes under each heading so the builder has a clear starting point. Leave answers blank until confirmed, then use the sheet to compare proposals and record handover. The FTC's 2014 guide recommends keeping project records together, so treat the completed sheet as part of that file. [1]

Start with your vision—a remodeled house or a custom home—and the constraints: a budget ceiling, a deadline, access limits or work hours. Then list ideas and existing information: drawings and plans, surveys, reports, approvals, photographs, measurements, warranties and correspondence, marking each as attached, requested or missing. Turn gaps into questions to ask the builder. For a home-improvement project, New York City's June 2026 guidance likewise advises listing the work, project specifics and budget limits before speaking with a contractor or builder; it excludes new home construction, plumbing and purely electrical work, so treat it as a local example, not a national rule. [2] [1]

Scope: what is included, excluded or assumed

Scope questions can set boundaries: what work is included, what is excluded, and what is assumed to be someone else's responsibility. Ask the builder for a detailed materials list rather than a category such as flooring. The FTC's March 2014 hiring guide recommended recording each product's color, model, size and brand, and naming who chooses any open item, with an allowance stating how much money is budgeted for it. Use the guide to draft your questions; contract requirements vary by jurisdiction. [1]

Ask a custom home builder how much customization is possible versus standard features and options, and how custom choices affect the price. The National Association of Home Builders' consumer question list suggests asking about appliance upgrades or downgrades and additional fees; it is industry guidance for new-home buyers, not a legal standard. For a custom home, have the home builder mark its floor plan with fixed items, custom details, upgrade options and open selections, then state who prices each one and when a selection becomes a change. Also ask the builder what the price covers. [3] [1]

Questions to ask a builder about who designs, approves, builds and inspects

Building work may involve a builder and several professionals, with design and construction divided among them. The FTC's 2014 guide describes a general contractor as managing the work, hiring and supervising subcontractors, obtaining permits and scheduling inspections; a specialty contractor as installing products; an architect as designing homes and major renovations; a designer or design-build firm as providing both. Ask the builder and each professional to confirm which role they will take, who is to lead the team, and which decisions remain yours to make. The description is general and dated; confirm local roles and requirements. [1]

Put every responsibility beside a name—yours, the builder's or a professional's: drawings, checks, permits, inspections, product approvals, revisions and completion records. Ask each to confirm the list in writing. The FTC's 2014 guide said a competent contractor would obtain the necessary permits, but rules vary. New York City's June 2026 guidance describes a local home-improvement contractor license and a way to check it; that license rule is local, not a national standard. Because building rules depend on the project location, record the licensing body, permit authority and inspection process once the site is chosen. [1] [2]

Use one scope to compare builder proposals and list open questions to ask

For homeowners, give every builder the same written scope of building work and a common response structure. Compare each builder's included and excluded work, materials, allowances, design and permit responsibility, costs and open questions line by line. Before you agree to hire, check the company's experience with projects like yours, its team's experience, how long the team has worked together, and how many years it has been in business. Request references from the builder's clients, including one from a project completed years ago, then ask those clients to comment on quality, and check reviews yourself. The FTC guide recommends several written estimates and warns that the lowest price may not be best. [1]

Keep a running list of questions in the worksheet. Give each question an owner, the date asked and a status: answered, answered with a caveat, or unanswered. Write down verbal answers and ask the builder to confirm them in the proposal; written notes help both sides to check what was agreed. The FTC guide cautions that promises made during conversations can be difficult to rely on later, so record them while the discussion is fresh. [1]

Before accepting a comparison, ask someone else to check whether the proposals explain why one costs more. If not, ask that builder to answer your questions about each difference using the same scope lines, and keep the explanation with the proposal. The FTC suggests asking for an explanation when estimates differ; it can expose an assumption never written into the price. [1]

Agree with the builder how to record revisions, communication and handover

Before building work starts, agree with the builder how changes will be authorized and how to ask questions about a proposed revision. The FTC's 2014 guide describes change orders as written authorization for a change or addition, potentially affecting cost and schedule. Ask who may request changes, who must approve them, which form to use, and how cost and time effects will be recorded before work proceeds. Put the current version in the changes block and retain superseded versions; a verbal instruction leaves no reliable trail. [1]

Agree how communication will work. Record the main contact for the owner and the builder, the preferred channel for routine questions, how to raise urgent site issues, and where to store decisions, plans, attachments and outstanding questions. Review the open-questions block at each meeting rather than leaving it until the end. The FTC guide recommends keeping contracts, change orders, correspondence and payment records together, and keeping one log of calls and conversations. [1]

Plan handover with the builder before completion. List handover questions and documents to collect: a warranty for materials and workmanship, manufacturer information, maintenance instructions, inspection records, promised drawings, and confirmation that the site has been cleaned. Ask the builder to record what was received and what is still missing. The FTC's 2014 sign-off checklist included checking work against the contract, obtaining written warranties, confirming subcontractors and suppliers were paid, and checking the quality of the finished work. Treat that list as prompts to verify locally, not a current payment rule or legal requirement. Save copies with the worksheet; notes from handover discussions help if problems arise later. [1]
