A new home inspection is the last sanity check before you own a stack of problems. When my husband David and I bought our 1998 Austin fixer, we paid for a full new home inspection even though the house was anything but new. The report caught a failing water heater, a cracked vent boot, and missing insulation right above Mia's future nursery. That $450 inspection saved us roughly $4,000 in surprise repairs. Here's what I actually look for now, both as a homeowner and as someone who reads factory spec sheets for fun.
Why a New Home Inspection Matters Even on a Brand-New Build
Builders have their own inspectors. They also have a closing schedule. Those two things do not always align with your best interest. A new home inspection during the first year after construction can find settlement cracks, unsealed door thresholds, and the kind of sloppy electrical work that a city inspector waved through. I have walked new construction where the bathroom GFCI outlet was not actually wired to the breaker it was labeled on. That is not a cosmetic fix. That is a $300 electrician call. Do not skip this step just because the house smells like fresh paint and empty promises. The best time to schedule it is after the drywall mud has dried but before the builder's warranty clock starts ticking. Many builders allow a pre-drywall walkthrough, but that is not the same as a new home inspection. The walkthrough is for checking the floor plan. The inspection is for checking physics. I have seen the same shortcuts in a $400,000 production build and a $200 per square foot custom job. The difference is not the zip code. It is whether anyone looked behind the drywall before the paint went on.
What I Check First: The Expensive Stuff
Start outside. Walk the lot after a hard rain if you can. Water should move away from the foundation, not toward it. I look for downspout extensions that stop two feet from the slab. That single mistake has caused more basement leaks than any cracked wall. Inside, I go straight to the mechanical room. The HVAC filter should be clean and the unit should be right-sized for the square footage. Oversized units short-cycle and die young. Undersized units run forever and rack up utility bills. I also pull the access panel on anything that looks new. Builders call that cosmetic. I call it the place where a loose wire or a missing clamp shows up first.
The Two Inspections Most Buyers Skip
A standard new home inspection covers the house. It does not cover the sewer line or the septic system. In older neighborhoods, cast iron pipes can be half-collapsed and still drain. In new construction, a contractor can drop a tool down the cleanout and never mention it. Pay $150 to $300 for a camera scope. I also recommend a separate radon test if the house has a basement or a slab on grade. The combined cost still comes in under the price of one surprise repair. If the house is on a well, add water quality testing. That is not being paranoid. That is being the kind of buyer who does not make phone calls after closing.
The Mia Test: Safety Checks That Do Not Show Up in a Report
Mia is three and a half. She will climb, pull, and swing on anything. During any new home walkthrough, I am not just buying square footage. I am buying the distance between a window lock and a kid's reach. Check that window stops keep the sash from opening more than four inches. Check that cabinet drawers have soft-close or anti-slam hardware. Check that the water heater is set at or below 120 degrees. Check that the garage door sensors are level and the auto-reverse actually reverses when you hold the door open. These are not upgrades. They are minimums. If a builder tells you otherwise, get it in writing.
How to Read the Report and Build Your Punch List
The inspector hands you a report. You are not supposed to frame it. Separate the safety items from the cosmetic ones. Any mystery leak, electrical tick, or chimney issue goes on the list for the builder before closing. For a resale new home, you can renegotiate. I recommend itemizing every fix with a dollar estimate. A missing vent boot is a $40 part plus labor. A cracked shower pan is a $1,500 replacement. That spread changes how you negotiate. You do not need to be a contractor to say, "I will accept the house when this list is complete." The report is just paper. The punch list is the plan.
What to Pay for a New Home Inspection
In my part of Texas, a thorough new home inspection runs $300 to $600 depending on square footage. Inspector credentials matter more than price. Look for InterNACHI or ASHI certification. Ask if they carry errors and omissions insurance. And never hire an inspector who offers to fix what they find. That is a conflict of interest. Spend the money once. The report becomes the single best document you own after the deed. If the seller or builder offers to pay for the inspection themselves, take the money but pick your own inspector. A second set of eyes is cheap when you compare it to the cost of being wrong.
