New Construction Inspection Checklist for Massachusetts Buyers

A useful new construction inspection checklist is organized by timing, because each phase exposes a different set of conditions. Pre-drywall and final/pre-closing inspections address different stages of construction. If you have a one-year builder warranty, an inspection before its notice deadline can help document visible conditions after occupancy. Confirm the project's permitted access, actual warranty terms, and deadlines rather than assuming every phase or an eleven-month appointment fits your purchase.

A private home inspection complements the builder's quality-control process and municipal inspections. It does not replace either one or issue code approval. The goal is to document visible conditions while they can still inform questions, repairs, and follow-up.

New construction inspection checklist by phase

Ken Arnold Home Inspection offers pre-drywall, final-walk/pre-closing, and 11-month warranty inspections through its new construction inspection service. These are available planning checkpoints, not a three-inspection legal requirement or a package automatically included in every appointment. The actual scope depends on readiness, safe access, weather, installed systems, and the inspection agreement.

Before any phase: confirm access and readiness

A well-timed inspection is more useful than a visit before the agreed work is ready or after it has been concealed. Ask the builder or site contact to confirm:

• the date and time when the inspector may enter the property;
• safe access, sufficient lighting, and any required personal protective equipment;
• which utilities and permanent systems the responsible builder or property contact will have ready and operable;
• which roofs, attics, crawlspaces, panels, and mechanical areas can be reached safely;
• who will receive the report and how correction requests should be submitted;
• the applicable contractual or warranty notice deadline.

If a system is not installed, connected, powered, fueled, or safely accessible, have that limitation recorded and decide whether a return visit is feasible. The inspector does not turn on shut-down electrical or fuel supplies or operate shut-down systems; the responsible builder or property contact must arrange readiness. Do not treat “new” as a substitute for “ready to inspect.”

Pre-drywall inspection checklist

The pre-drywall phase provides a view of work that may later be hidden. The inspection remains visual and non-destructive, but open framing can make routing, fastening, connections, penetrations, and water-management details easier to see. Confirm which observations are included in the phase agreement; these examples are not a substitute for an engineering or trade inspection.

Framing and structure

• Visible beams, posts, bearing points, wall framing, floor framing, roof framing, and connectors
• Field cuts, notches, holes, splits, or displaced components that merit builder review
• Window and door openings, visible flashing preparation, and transitions between assemblies
• Visible fire-blocking or draft-stopping details only where included in the agreement and within the inspector's qualifications—not fire-rating or code certification

Rough systems

• Visible supply, drain, vent, gas, and primary electrical distribution routes through framing
• Accessible HVAC ducts, duct boots (fittings that connect ducts to room air outlets), equipment locations, exhaust paths, and return-air provisions
• Penetrations through exterior surfaces or assemblies that will later be concealed
• Potential conflicts between mechanical work and structural framing

Low-voltage and ancillary wiring, such as security or data cabling, is outside the required standard electrical inspection scope. Ask about a separate appropriate review if it matters to your project. Keep the report focused on observed conditions, then ask the builder how each finding will be evaluated and addressed; the report is not a set of construction instructions.

Final inspection before closing

Arrange the final inspection when the work within the agreed scope is sufficiently complete, utilities are ready, appliances and fixtures are installed, and safe access is available. If significant work remains, clarify whether a later reinspection is part of the plan.

Exterior and site

• Roof surfaces and penetrations from safe, accessible vantage points
• Siding, trim, windows, doors, decks, porches, steps, railings, and visible flashing
• Grading, drainage paths, foundation exposure, driveway, walkways, and exterior utility connections
• Gutters and downspouts, including where water is discharged

Interior and installed systems

• Representative windows, doors, cabinets, counters, stairs, railings, floors, walls, and ceilings within the agreed scope
• Electrical panels, representative receptacles and fixtures, and accessible safety devices within the inspection scope
• Plumbing fixtures, drains, accessible supply connections, water heating, and visible leakage
• Heating, cooling, ventilation, and normal operating controls when safe operating conditions allow
• Attic, insulation, basement or crawlspace, garage, and accessible structural components

The builder's cosmetic punch list and the home inspection report may overlap, but they are not identical. A paint touch-up, a leaking connection, an unsafe guard, and an inaccessible system should not be treated as the same kind of item.

11-month warranty inspection checklist

If your purchase includes a one-year builder warranty, start with its coverage dates and required notice method. Schedule with enough time to receive the report and submit any notice before the actual deadline; month eleven is a service label, not a universal legal deadline. Do not wait for that appointment to report an active leak or other urgent condition.

• Recheck prior limitations and items that were incomplete at the final inspection.
• Have the inspector evaluate visible water entry, drainage problems, plumbing leakage, or condensation that developed after occupancy.
• Point out unusual cracking, movement, binding doors or windows, and finish changes that may warrant evaluation.
• Have accessible heating, cooling, plumbing, and electrical systems reviewed under appropriate operating conditions.
• Review attic, basement, crawlspace, garage, and exterior conditions after seasonal exposure where accessible.
• Separate warranty questions from routine homeowner maintenance.

An 11-month inspection is not a warranty-coverage decision and does not guarantee a builder-paid repair. The warranty documents are the starting point for coverage, notice, exclusions, and deadlines; have the appropriate adviser address interpretation and other applicable legal rights. The inspection supplies a current record of visible conditions for the owner to use in that process.

Understand the role of each review

The Massachusetts Home Inspectors Consumer Fact Sheet explains that a standard home inspection is a visual examination of readily accessible, exposed portions of the structure and major systems. It distinguishes a home inspection from a building-code inspection, appraisal, or guarantee. The state's 266 CMR 6.00 Standards of Practice sets the professional scope, including access and operating limitations, for Massachusetts home inspectors.

Turn the report into builder-ready questions

1. Prioritize safety and active damage. These deserve prompt attention and clear communication.
2. Group related observations. A ceiling stain, flashing concern, and drainage issue may require one coordinated investigation rather than three disconnected notes.
3. Identify the next qualified party. Some conditions call for the builder; others may need a licensed electrician, plumber, HVAC contractor, structural engineer, or another specialist.
4. Track status without rewriting the report. Mark items accepted, corrected, scheduled, disputed, or awaiting more information.
5. Recheck significant corrections when appropriate. A photo or statement of completion may not show whether the repair changed the observed condition.

To understand how findings are organized, review the company's sample inspection reports. A clear report should help the buyer distinguish the observation, its implication, and the recommended next step.

Build the timeline backward from your deadline

Start with the closing date or actual warranty notice deadline, then allow time for the inspection, report delivery, builder review, specialist follow-up, and any agreed reinspection. Construction schedules move; keep access and readiness confirmed in writing and avoid assuming that a previously discussed date is still workable.
