    New Construction Builder Warranty: What Buyers Should Know

    The 1-2-10 warranty is industry standard, but most buyers miss the 11-month deadline that protects them for the next decade. Here's how it actually works.

    One of the advantages of buying a new construction home is knowing that you're not buying a house with years of someone else's wear and tear. But new doesn't mean nothing will go wrong.

    • A door may need adjustment.
    • A cabinet may shift.
    • An HVAC component may stop working.
    • A window may develop an issue.
    • A leak may appear after a heavy rain.

    When something happens in a brand-new home, the first question is usually:

    "Is the builder responsible for fixing this?" The answer depends on the problem, the warranty terms, the component involved and sometimes the manufacturer. That's why understanding your builder warranty before you need it is worth your time.

    What Is a Builder Warranty?

    A builder warranty is a commitment from the builder covering certain defects or problems in the home for a specified period, subject to the terms and exclusions of the warranty. The exact coverage varies. There is no single nationwide builder warranty that applies to every new construction home. Your builder's warranty documents are what determine your actual coverage. Some warranties may address different categories of issues for different lengths of time. For example, a builder may have separate coverage provisions for:

    • Workmanship
    • Materials
    • Certain systems
    • Structural components

    The specific time periods and exclusions depend on the builder and warranty program. Don't assume that every builder uses the same warranty.

    Builder Warranty FAQ

    What is a 1-2-10 builder warranty?
    A 1-2-10 warranty is the industry-standard new construction warranty: 1 year on workmanship and materials (paint, drywall, tile, trim), 2 years on systems (plumbing, electrical, HVAC), and 10 years on major structural defects (load-bearing walls, foundation, roof framing).
    Who actually backs the 10-year structural warranty?
    Most national builders use a third-party warranty company like 2-10 Home Buyers Warranty, StrucSure, or Quality Builders Warranty (QBW). If the builder goes out of business, the warranty company still honors the structural coverage. Always ask which company backs the warranty and request the actual policy document, not just the summary.
    What's NOT covered by a new construction warranty?
    Cosmetic items after 1 year, normal wear, settling cracks within tolerance (usually 1/4 inch), landscaping, appliances (covered by their own manufacturer warranties), damage from owner modifications, and anything outside the published warranty standards. Pest infestations, mold caused by humidity, and concrete hairline cracks are commonly excluded.
    How do I file a warranty claim?
    Submit claims in writing through the builder's official warranty portal or the email address in your warranty booklet, never verbally to the superintendent. Document with photos, dates, and a written description. Keep copies of everything. For systems and structural claims, file with both the builder and the third-party warranty company at the same time.
    What is the 11-month walkthrough?
    Before your 1-year workmanship warranty expires, walk the home top to bottom and create a punch list of every defect, nail pops, sticking doors, cracked grout, paint touch-ups. Submit it in writing to the builder before month 12. This is the most important warranty deadline of the entire 10-year coverage.
