The pre-drywall inspection is the one window to see inside your new home's walls. Here's what to check, who to bring, and the photos you'll thank yourself for.
There's one day in your entire build where you get to see everything — every wire, every pipe, every duct run, every stick of framing — before it disappears behind drywall forever. Most buyers walk that day with their builder, nod politely at the studs, take a photo for Instagram, and head home.
That's a missed opportunity, and honestly, it's one of the biggest ones in the whole building process.
I've walked a lot of pre-drywall inspections with buyers across Johnson County, and I want to give you the same checklist I use — because once the drywall goes up, fixing what's behind it stops being a punch-list item and starts being a change order.
What the Pre-Drywall Walk Actually Is
Somewhere between rough-in and insulation, your builder will invite you to a pre-drywall walkthrough. The house has its bones: framing complete, roof on, windows in, and the mechanical trades — electrical, plumbing, HVAC — roughed in but fully exposed.
This is not a ceremonial visit. It's a working inspection, and it's the only one where you can verify what's inside your walls against what you actually bought.
Two things to arrange before you go. First, ask your builder how much time you'll have — you want a real hour, not fifteen minutes on the way to another appointment. Second, seriously consider bringing your own third-party inspector. Yes, even on a new build, and yes, even with the excellent builders we have working across Johnson County. A pre-drywall inspection from a licensed inspector typically runs a few hundred dollars, and it's the cheapest insurance you'll buy in the entire transaction. Municipal inspections check code minimums — your inspector checks workmanship.
The Checklist: What to Verify While You Still Can
Framing and structure. Look for cracked or bowed studs, floor squeaks, and framing that's been notched or drilled heavily to route pipes and wires — there are limits to how much material can come out of a load-bearing member. If something looks improvised, ask about it now.
Electrical rough-in. Walk every room with your selection sheet. Count the outlets. Confirm switch locations actually make sense for how the room will live — you'd be amazed how often a switch ends up behind where the door swings. Verify your upgrades made it in: the floor outlet in the great room, the sconce boxes flanking the primary bath mirror, the 220 line in the garage for the EV charger you mentioned once in the design center.
Plumbing rough-in. Confirm fixture locations against the plan, especially anything you moved or upgraded. Check that tub and shower valves are set for the fixtures you selected. If you paid for a rough-in — future basement bath, a pot filler, a gas line to the patio — this is the day you confirm it exists.
HVAC and ducts. Look at where the supply runs land in each room and ask about returns on every floor. Bedrooms over garages and bonus rooms are the classic comfort trouble spots in our climate — August in Kansas will find every shortcut in a duct design.
Blocking. This is the sleeper item. Blocking is the extra lumber inside the wall that gives future you something to anchor into: towel bars, the TV over the fireplace, heavy mirrors, closet systems, grab bars in a main-floor bath if you're thinking long-term. It costs almost nothing to add today and requires opening the wall later.
Windows and exterior. Check for cracked glass, confirm window operation, and look at the flashing and house wrap details around openings while they're still visible.
Take the Photos. All of Them.
Before you leave, photograph every wall of every room, floor to ceiling, with something in frame for scale. Ten years from now, when you're hanging shelves or your electrician is hunting a junction box, those photos are a map of everything behind your drywall. I've had past clients tell me this was the single most useful thing they did during their build.
Where This Fits in the Bigger Picture
The pre-drywall walk is one checkpoint in a longer sequence of protections. Your contract set the ground rules months earlier — if you're still at that stage, my breakdown of the builder contract clauses worth reading twice is where to start. And at the other end of the build, the final walkthrough and punch list is your last formal pass before closing — much easier when you already know what went into the walls.
This is also exactly the kind of moment where having your own agent on a new build earns its keep. The builder's superintendent runs the walk; your agent makes sure your questions get answered and documented. If you're still deciding who's building your home, my guide to custom home builders in Johnson County covers the names you'll be choosing between — and communities like Sundance Ridge and Mills Farm each have their own mix of builders and processes worth understanding before you sign.
The Bottom Line
You get one look inside your walls. Bring your selection sheet, bring an inspector, bring your camera, and treat that hour like the inspection it is. Everything you catch at pre-drywall is a conversation; everything you catch after closing is a project.
