With a new construction home, the International Association of Certified Home Inspectors recommends you have two or three inspections on the property.
The first inspection is called a foundation or “pre-pour” inspection and occurs just before the foundation is poured on the home. This one ensures the site has been excavated and graded properly, that anchors and footing are adequately spaced and in place, and that the stage is set for a strong and long-lasting home. In the event the inspector finds issues on this go-around, it allows the builder to make adjustments before pouring the foundation (when there’s generally no going back).
The second inspection you might consider is a framing or “pre-drywall/sheetrock” inspection. This one happens after the entire frame has been built, the roof is on and the windows are installed, but before the sheetrock and walls are put up. It allows the inspector to make sure the beams, posts, studs, and other structural components are installed properly, as well as check things like the wiring, plumbing, window flashing, and other elements that are generally hidden behind the wall. If any problems crop up on this inspection, your builder can fix them before going further with the project.
The final and third inspection is the one you would have on any resale property—the one that ensures the home is safe for occupancy and has been finished per local code and building standards. Anything your inspector finds on this inspection should be remedied by your builder before closing.
