Pre-Drywall Inspection Checklist for Yorkville Buyers

Do you need a pre-drywall inspection on a new construction home in Yorkville?

Yes, if the builder will allow it. A pre-drywall inspection is your one chance to have a licensed home inspector look at the framing, wiring, plumbing, ductwork, and insulation before drywall covers them for good. The city inspector checks the work against the adopted building code for the builder’s permit, not for you, so a separate inspection gives you your own written record. Get the right to that visit written into the builder’s purchase agreement before you sign, because after you sign, access is up to the builder.

New construction is what buyers ask me about most in Yorkville right now, and the pre-drywall inspection is the step many have never heard of until the walls are closed.

The questions online repeat every week: “Is it worth it when the city already inspects?” “The builder won’t let my inspector in. Can they do that?”

Here is how the pre-drywall inspection works in Yorkville, Oswego, and Montgomery, what to put in writing before you sign, what to check on the day, and what to do with the report.

Why the city inspection isn’t your inspection

Every new house in Yorkville is built under a city permit, and the city inspects the work as it goes. That is real protection, but it is not the same thing as a pre-drywall inspection you hire.

Start with who the city process serves. The United City of Yorkville’s building permit information page says it is the property owner’s responsibility to make sure all necessary inspections are performed, and inspections must be requested at least one working day ahead.

Until closing, the owner of your lot is usually the builder. The builder schedules those visits, and the results go into the builder’s permit file.

Then look at the yardstick. Yorkville’s permit pages list the 2018 International Codes, including the 2018 International Residential Code. The Village of Oswego adopted the 2021 International Residential Code beginning October 1, 2024, and Montgomery lists 2021 ICC codes.

Code is a legal minimum. A house can pass every city visit and still have a crushed duct or an outlet nowhere near where your couch goes.

Illinois law draws the same line. Under the Home Inspector License Act (225 ILCS 441), anyone who performs home inspections for pay in connection with a sale needs a license from the Illinois Department of Financial and Professional Regulation (IDFPR). City and village code officials are exempt from that license while doing their government job, which is code compliance, not a report for you.

There is one more gap. The Illinois Residential Real Property Disclosure Act exempts transfers of newly constructed homes that have never been occupied (765 ILCS 77/15(9)).

On a resale, the seller’s disclosure report starts the conversation about known problems. On a never-lived-in home, there is no report, so your inspections do that work.

If you’re buying a finished spec home, my guide to buying move-in ready homes in Yorkville covers what you can still check. If your home is still a slab and a set of plans, you have a window that spec buyers don’t.

Buyers on r/FirstTimeHomeBuyers put it plainly. One poster wrote that city inspectors “are checking code minimums and moving fast, not really looking out for you specifically.”

Get pre-drywall inspection access in writing before you sign

This is where buyers usually lose the pre-drywall inspection, and it happens weeks before the framing goes up. Builders typically sell on their own purchase agreement rather than the standard resale contract, and that agreement controls whether anyone you hire can walk the site before closing.

Some builders welcome third-party inspectors. Others limit them to the final walk or say nothing at all, which leaves the decision to whoever answers your email.

In one r/RealEstate thread, a buyer said a national builder “stalled for 2 weeks and ultimately refused to allow him entry,” after the buyer had already paid the inspector. The replies agreed: if the contract is silent, the builder can say no.

So read the access section before you sign, and ask for these points in writing:

• A pre-drywall inspection right. Your licensed inspector may walk the home after the rough-ins and before insulation and drywall.
• Notice. The builder tells you or your agent when rough framing, electrical, plumbing, and mechanical work is ready, with enough lead time to book an inspector.
• Who can attend. You, your agent, and your inspector, with any site-safety rules spelled out.
• How findings get handled. A written response to each item, and photos of corrections before the walls close.
• A final inspection right. A separate visit before closing, scheduled ahead of the builder’s orientation walk.

This is the “why the right agent matters” part of new construction. The builder’s sales team works for the builder.

Many builders also want your agent registered at your first model visit, which is why my new construction guide for Yorkville, Oswego, and Montgomery says to bring your own agent from day one. Your agent should be the person asking for inspection access while you still have negotiating room, not the person telling you an inspection isn’t needed. One r/FirstTimeHomeBuyer poster’s agent kept saying exactly that, and the replies were blunt: get the inspection.

Pre-drywall inspection checklist for Yorkville buyers

Once access is in writing, the hard part of a pre-drywall inspection is timing. The window between the city’s rough inspections and insulation can be short.

Before the visit

• Confirm the inspector’s license. Search the name on the IDFPR license lookup. The Act also requires inspectors to carry general liability insurance of at least $100,000.
• Sign a written agreement first. Illinois’ home inspection standards of practice (68 Ill. Adm. Code 1410.200) require a signed contract before the inspection that lists the systems and components covered and any limitations. Make sure it says “pre-drywall” and names what will be open to view.
• Time it after the city’s rough approvals. Ask the builder’s construction manager to tell you when the framing, electrical, plumbing, and mechanical rough inspections pass, then book your inspector before insulation goes in.
• Bring your floor plan and options sheet. Your inspector checks condition. You check that what was built matches what you bought.

What the inspector looks at

Illinois’ standards define “inspect” as a visual check of readily accessible systems, so the inspector reports what can be seen with the walls open. At pre-drywall, that usually includes:

• Framing and structural components: walls, headers, beams, and the floor and roof structure.
• Rough electrical: wiring runs, boxes, and panel location.
• Rough plumbing: supply and drain lines, vents, and how pipes pass through framing.
• HVAC: duct routing, connections, and supports.
• Windows, exterior doors, and flashing, plus signs of water getting in.
• Insulation and vapor retarders where already installed.

What you check yourself

• Outlets, switches, and lights in the places you’ll actually use them. Walk each room as if the lights are off.
• Backing for TV mounts, grab bars, towel bars, and heavy shelves.
• Every option you paid for: extra outlets, a gas line, pendant lights, a basement bath rough-in.
• Photos or video of every wall and ceiling, labeled by room. You’ll use them for years.

What to do with the report

The standards require a written report within 2 business days of the pre-drywall inspection, with the inspector’s name and license number.

Two other rules help you here. The inspector may not deliver the report to anyone but you without your written consent, so you decide what the builder sees. And the inspector may not advise you whether to go through with the purchase, so read the report as a list of conditions, not a verdict.

Send the builder the items you want addressed in writing, through your agent, and ask for a written answer on each one. For anything that will be covered, ask for a photo of the fix before insulation, or a quick recheck by your inspector. A short, specific list with photos gets a better response than a long PDF.

Then keep two more dates on your calendar. The first is the final inspection before closing.

Yorkville’s residential permit application states that the owner agrees not to occupy the building until all inspections are performed and a certificate of occupancy is issued, so ask for proof of the certificate of occupancy before closing day. The second is the walkthrough before your one-year warranty mark, which I explain in my post on builder warranty coverage in Illinois.

One local tip: the same Yorkville application says the permit is a public document under the Illinois Freedom of Information Act. If the builder can’t tell you what has been inspected on your lot, ask the city.

Questions Yorkville buyers ask about a pre-drywall inspection

These come up with nearly every new construction buyer I work with.

Plan your new build inspections with a local broker

A pre-drywall inspection costs you one visit and gives you a record of the parts of your house you will never see again. The time to secure it is before you sign the builder’s agreement, not after the framing goes up.

If you’re looking at a new build in Yorkville, Oswego, Montgomery, or anywhere in Chicago’s Western Suburbs, I’ll go through the builder’s contract with you, ask for inspection access in writing, and help you plan the pre-drywall and final visits around the build schedule.
