New-home 11-month builder warranty inspection checklist

A comprehensive pre-deadline new-home warranty inspection checklist for reviewing contract and warranty dates, prior repairs, structure and movement, roof and exterior water management, foundation and drainage, plumbing, electrical, HVAC and ventilation, insulation and moisture, interiors and safety, seasonal limitations, specialist referrals, formal written notice, correction verification, and preservation of unresolved claims before common first-year milestones expire.

Warranty documents, legal or contractual deadlines, exclusions, prior notices, and repair history are organized first

Critical item

The inspection and notice plan should use the actual documents and preserve every relevant date and unresolved condition.

Roof, attic, cladding, openings, flashing, decks, foundation, grading, drainage, and exterior systems are reviewed after seasonal exposure

Critical item

The exterior and site should manage water, weather, loads, and movement without active leakage, unsafe condition, or unresolved installation defect.

Plumbing, electrical, gas, HVAC, ventilation, appliances, safety devices, and controls are functionally reviewed

Critical item

Systems should operate safely and consistently with commissioning, listing, design, and owner documentation.

Structural movement indicators, floors, walls, ceilings, stairs, guards, doors, windows, cabinets, tile, and finishes are mapped

Critical item

Observed movement and defects should be measured, located, and referred appropriately rather than dismissed or overstated.

Inaccessible, structural, environmental, roof, sewer, HVAC, electrical, plumbing, pool, well, or septic concerns receive timely specialist review

Critical item

A general inspection should identify when qualified design, trade testing, environmental assessment, camera work, laboratory sampling, or seasonal follow-up is needed.

Formal warranty notice, builder response, correction scope, access, retesting, and unresolved rights are tracked to verified completion

Critical item

Each item should be submitted and closed according to controlling documents without waiving unresolved conditions through informal status updates.

Use early enough before the applicable builder or component warranty milestone to inspect, obtain specialist input, and deliver notice through the required channel. โ€œ11-monthโ€ is a planning convention, not a universal legal deadline; actual rights, exclusions, statutes, and notice dates vary by contract and jurisdiction. Do not enter unsupported excavations, walk incomplete framing or roofs, open energized equipment, operate pressurized systems without authorization, or interfere with required inspections. Use qualified inspectors and licensed trades for inaccessible, structural, electrical, gas, mechanical, environmental, or life-safety conditions.
