The 10-year warranty covers which of the following?

• A. Building envelope
• B. Structural defects
• C. HVAC
• D. Doors and windows

Answer: (B)

In new-home warranties, the 10-year period is aimed at protecting the building’s structural integrity. It covers major defects that affect the safety and stability of the home—things like foundation movement, framing failures, and other load‑bearing structural elements. Non‑structural items aren’t included in this long-term coverage.

That’s why other components aren’t the focus here: the HVAC system is a mechanical system typically covered for a shorter period, doors and windows usually come with their own product or builder warranties, and issues with the building envelope (the exterior shell) are typically addressed under different terms or separate warranties. So the 10-year warranty best fits structural defects.
