New Home Warranty: What It Covers and the Exclusions Builders Rely On

New home warranties come in two forms: the expressed warranty provided by the builder in writing, and the implied warranty of habitability recognised in most states. Most buyers know about the expressed warranty — the written document the builder hands them at closing. Few buyers know that the implied warranty provides additional protection that exists regardless of what the expressed warranty says.

Standard Builder Warranty Coverage

The Exclusions That Matter Most

Four exclusions that builders rely on to deny warranty claims: (1) “Normal building movement” and settlement: all homes settle. Builders define “normal settlement” broadly enough to exclude many visible cracks, misaligned doors, and flooring gaps. The line between “normal settlement” and a warranted structural defect is often subjective and contested. Document all cracks photographically at closing and at 6-month intervals. (2) Consequential damage: most builder warranties exclude damage caused by the defect (water damage from a leaking window, mould from inadequate waterproofing). They may repair the defect but deny responsibility for the consequential damage. (3) Landscaping and drainage: site drainage and landscaping are often excluded from the structural warranty. But drainage failures that cause water intrusion into the foundation can cause structural damage — a chain of causation that creates warranty disputes. (4) Pre-existing conditions you “accepted”: items identified on the punch list and accepted at closing — even if “accepted” means the builder promised to fix them — may be treated as closed issues if not properly documented.

Self-Insured vs Third-Party Insured Warranty

The most important warranty question most buyers never ask: is this a self-insured builder warranty or a third-party insured warranty? (1) Self-insured warranty: the builder promises to repair defects using their own resources. If the builder goes bankrupt, closes, or is acquired, the warranty obligation may go with them. (2) Third-party insured warranty: a warranty backed by an insurance company (2-10 Home Buyers Warranty, Buckeye National, QBW). If the builder can’t perform, the insurance company is obligated. This is materially more valuable than a self-insured warranty, particularly for smaller and regional builders. (3) Ask before signing: request the warranty document and confirm whether it is self-insured or backed by a specific insurer. If self-insured, ask about the builder’s financial stability and track record on warranty claims.

Implied Warranty of Habitability

Most states recognise an implied warranty of habitability for new construction that supplements the expressed warranty: the builder implicitly warrants that the home is fit for human habitation. This implied warranty cannot typically be waived by contract and provides protection for defects that affect livability. Courts have applied the implied warranty to: structural defects that make the home unsafe, plumbing failures that affect sanitation, and building envelope failures that allow water intrusion. The implied warranty does not cover cosmetic issues, normal settlement, or defects below the habitability threshold. If the builder’s expressed warranty denies a claim that you believe affects habitability, consult a real estate attorney in your state — the implied warranty may provide an additional avenue.

How to Protect Yourself

Five steps to maximise warranty protection: (1) Document everything at closing: photograph every room, every system access point, and every exterior surface. Date-stamped photos establish the condition at closing. (2) Complete the punch list before closing: items left on the punch list at closing become warranty claims — a weaker position. Push for completion before signing. (3) Submit warranty claims in writing: all warranty claims should be submitted in writing (email is fine) specifying the defect, location, and date first noticed. Verbal reports are not documented claims. (4) Know your state’s statute of limitations: warranty claims have filing deadlines. Most states have 4–10 year statutes for construction defects. Missing the deadline forfeits the claim. (5) Consider a home warranty: a third-party home warranty (separate from the builder’s warranty) covers systems and appliances the builder’s warranty excludes after year 2. Worth evaluating at closing.

Frequently Asked Questions

What does a new home builder warranty cover?

Typically: workmanship for 1 year, mechanical systems for 2 years, and structural components for 10 years. Common exclusions include settlement-related cracks, consequential damage, landscaping drainage, and cosmetic issues after year 1.

What is the difference between a self-insured and third-party warranty?

A self-insured warranty is backed only by the builder’s own resources. If the builder goes bankrupt, the warranty may be worthless. A third-party insured warranty is backed by an insurance company and survives builder bankruptcy. Always ask which type the builder provides.

What is implied warranty of habitability for new construction?

A legal warranty recognised in most states that the home is fit for human habitation, regardless of what the expressed warranty says. Cannot typically be waived by contract. Covers defects that affect livability — structural failures, plumbing failures, and building envelope failures that allow water intrusion.

How do I make a warranty claim on a new home?

Submit all claims in writing (email) specifying the defect, location, and date first noticed. Accompany with date-stamped photographs. Know your state’s statute of limitations for construction defects (typically 4–10 years). Do not rely on verbal reports to the builder’s warranty line.
