An inspection is still necessary before closing on new construction. It is easy to understand why a buyer could presume that a new home has no issues, but regardless of its squeaky clean appearance it will behoove any buyer to conduct both an inspection and a final walk-through. An inspection will ascertain that everything is in working order and that all items that are meant to be included are completed and in place.
Construction projects usually end with punch-list items that are yet to be finished, an inspection will point out what punch-list items have been completed and what items still need to be attended to. Once the home has closed the chance of repairs being made become less likely as the builder considers the project complete.
Often when buying new construction a Realtor is not involved but don’t let the builder snowball you into leaving important items like the inspection objection clause off of your contract to buy. It would be a shame to move in to a new home and not have the hook-ups in place to install a washer and drier for example, have a bathroom that is missing a shower, or have appliances that were part of the deal absent from the home. Bottom line: an inspection is important no matter if the real estate is new or old.
