A home inspection is an important step in the buying process, even for new construction homes. Here are a few reasons why you should consider getting a home inspection for a new construction home:

First, lets explain how most builders operate. Typically, mostly everything is subcontracted. Other companies are hired to perform the work and I think you would be surprised to see how little oversight there actually is. 

If a plumber makes a mistake (or several) the mistakes are typically only corrected when they are found or when a leak, clog or issue occurs. If you are relying that the superintendent is thoroughly looking at this or even if they know what to look for, then you are simply leaving it up to chance. If you are relying on a code inspector (from the county building department) to find all the items, well understand they only inspect certain steps and not everything (very minimal actually).

A lot of different contractors work on the home, many of these contractors can cause discrepancies on other systems in the home. For example, the siding or painting contractors can cause damage to the roof while working on the siding above the roofline. The shingles often get damaged from ladders and equipment while working. An electrician can do a repair, but never puts the insulation back at the walls or ceiling. The drywall contractor can just forget to cutout an air vent and then its out of sight out of mind. So even if the components are okay after install, it doesn't mean they will be okay after additional contractors finish their job.  

These are just a few things we find on a routine basis and its more common than you think. We always find multiple discrepancies with every new construction home we do, so expect some issues. There could be significant discrepancies or maybe only minor ones, but either way the builder will spend a lot more fixing the items than what the inspection costs. For that reason alone, the inspection is worth it, but of course there are many other reasons. 

Sure, you can wait until the builder warranty to have the home inspected, but the warranty will only cover certain things and you simply lose all the leverage if you wait until after closing. The builders will often give way more attention to a home that has been professionally inspected and less attention to a home that hasn't been. 

In conclusion, a home inspection for a new construction home is an important step in the buying process. It can help ensure the safety and stability of the home, allows you to get a much better product and avoid unexpected costs.
