One reason a buyer might choose to buy a “new build” home is the expectation that it will be free from the issues that are found in older homes- like outdated plumbing and electrical, a worn-out furnace, a roof that needs replaced, or being less energy efficient. However, new construction homes have their share of problems, as well.
Building a home is a complex orchestration involving many different subcontractors. Each subcontractor works independently on different aspects of the construction, usually without regard to the others’ work. With all the separate activities occurring at the same time, it is nearly impossible for the builder to carefully check everybody’s work and can often lead to construction defects and poor workmanship being overlooked.
Even the best builders will likely miss something.
Ideally, you want to have a newly built home inspected twice. First, while under construction, just before the drywall is hung. The second time is when the home is finished, right before the final walk-through with the builder.
