Common Issues found during Pre-drywall and New Home Construction Inspections

IMG 3032 e1514825250844

Every week I hear home buyers say that they do not need a home inspection on a new construction because both the builder and the county code enforcement officers have gone through the house and have given their OK.  Most if not all of issues or concerns in the following list were found after builder and code inspections.  Building codes are basically a set of minimum standards by which constructing a home to any lessor degree is essentially illegal.  So building to local building codes is simply complying with local minimum standards; it does not guarantee that “best practices” are used in constructing the house. In case you have any doubt as to whether to have your new home inspected by an independent professional inspector, this list will help clarify the need for one.  In the future, I will post on specific defects and why it is important to discover and correct them before further issues arise.

When inspecting pre-owned homes, I consider some conditions as cosmetic or part of the house’s character, such as, small cracks, nicks and gouges in trim, doors that rub slightly.  However, when I am inspecting a brand-new home, I will hold them to a higher standard, and these conditions become a sign of the level of workmanship and oversight.  Your new home is a very complicated structure with many systems that have to work together.  The general contractor builds your new home from scratch on site with many different sub-contractors coming and going. With schedules and budgets to maintain, they inevitably are forced to make compromise choices. When a functional issue is found, or cosmetic issue is obvious, the builder should and usually does agree to fix it.  The homebuyer needs to know that “new” does not mean “perfect”.

If you are thinking or the builder has suggested that a home inspection is not necessary for a new home, here is a list of issues that I have recently found in new home construction.
