Yes. The ‘new’ part of a new home implies many warranties, both on equipment and workmanship, but it doesn’t guarantee that everything was built, connected or installed perfectly. And as builders continue to fight to keep costs down, the labor from which they draw is increasingly less skilled.
Most home inspectors will offer a bit of a modified version of a home inspection for new homes that is more akin to a punch list walk through on steroids where they spend less time inspections the mechanical condition, and focus more on the installation and aesthetics. It is a valuable exercise that we highly recommend.
