Do I need my own inspection on a new construction home in Maryland?
Yes, get your own inspector. The county inspector checks code minimums, the builder's quality manager works for the builder, and neither one reports to you. An independent pre-drywall and final inspection on a Maryland new build runs about $700 to $1,100 combined, and it routinely finds items the walkthrough never would.
We get this question most from buyers at South Lake in Bowie, where Ryan Homes is building four level townhomes fast enough that trades overlap on the same block. But the answer is the same at a Toll Brothers single family home in Germantown or a Lennar townhome in Frederick. Here is what the inspections cost, what each one catches, and how to handle a sales office that says you don't need one.
What does a new construction inspection cost in Maryland?
Plan on $300 to $600 per visit, and two or three visits over the life of the build. Maryland inspectors price new construction by stage rather than by house size, and the ranges below are what buyers in the Baltimore and Washington suburbs are quoted today:
| Stage | When | Typical Maryland price |
|---|---|---|
| Pre-drywall inspection | Framing, rough plumbing, electrical and HVAC done, insulation not yet covered | $300 to $500 |
| Final inspection | A few days before your builder walkthrough | $400 to $600 |
| 11 month warranty inspection | Month 10 or 11 of ownership, before the one year builder warranty ends | $300 to $500 |
| Optional: foundation or pre-pour | Before the slab or basement floor is poured | $250 to $400 |
Townhomes run at the low end, a 4,000 square foot single family at the high end. Thermal imaging and a sewer scope, which we recommend on any home with a finished basement, add $100 to $250. Set against a $460,000 townhome or a $1 million single family, the whole program is a rounding error, and your buyer agent credit at closing usually covers it several times over.
What does a pre-drywall inspection actually catch?
The things you will never see again once the drywall goes up. On Maryland new builds the recurring finds are missing or crushed insulation behind tubs and in rim joists, HVAC ducts disconnected in the attic, notched or over drilled floor joists where the plumber ran drain lines, nail plates missing where wiring passes through studs, window flashing lapped the wrong way, and roof truss bracing left off. None of those fail a county framing inspection on their own, and every one of them turns into a comfort or moisture problem you pay for later. The builder's own project manager may fix all of it if you hand them a list; the point is that nobody else is looking on your behalf.
Isn't the county inspection enough?
No. County inspectors in Prince George's, Anne Arundel, Montgomery and Frederick counties check that the work meets the adopted building code, and they spend minutes per house on a route of dozens. Code is a legal minimum, not a quality standard, and it says nothing about a warped cabinet run, a sloped deck, a bathroom fan venting into the attic, or a grade that drains toward the foundation. Maryland also does not license home builders the way it licenses electricians; builders register with the Home Builder Registration Unit at the Attorney General's office, which handles complaints after the fact. Prevention is on you.
Will Ryan Homes or Toll Brothers let me bring an inspector?
Yes, with rules, and the rules are in the contract you sign. Every large Maryland builder allows a third party inspector at pre-drywall and final. Most require the inspector to be licensed, scheduled through the project manager, and accompanied by a builder employee. Some limit the visit to a set window and prohibit the inspector from touching anything. What a sales rep may tell you at the model, that "our quality process makes it unnecessary," is a sales line, not a policy. Ask for the inspection clause in writing before you sign, and read the rest of the contract with our list of Maryland builder contract gotchas next to it.
Two practical points. First, the builder decides the schedule, so tell your project manager at the pre-construction meeting that you are bringing an inspector and want 48 hours notice before drywall. Second, the builder is not obligated to fix everything on your inspector's report, only what violates code, their own specifications, or the contract. In practice the good project managers fix nearly all of it because the list is usually short and the fixes are cheap before drywall.
How the timing fits a Maryland build
- Pre-construction meeting. Tell the project manager you will have an independent inspector at pre-drywall and final. Get their notice policy.
- Pre-drywall, usually 8 to 14 weeks after foundation. Inspector walks framing, mechanicals and insulation. You forward the report to the project manager the same day.
- Final inspection, 3 to 5 days before your walkthrough. Inspector tests every outlet, window, fixture and appliance, runs water everywhere, checks grading and the roof. Their report becomes your walkthrough punch list.
- Walkthrough. Go through the report item by item with the builder rep and get every open item written on the builder's form. We attend this one with you.
- Month 11. Warranty inspection before the one year coverage runs out. Submit the list in writing to the builder's warranty department.
What if the builder's warranty covers it anyway?
The warranty helps, but it is narrower than buyers assume. Under Maryland Real Property section 10-604, a new home warranty security plan covers workmanship and materials for one year, systems for two, and major structural defects for five, and a builder can offer a plan that meets those terms or disclose in writing that it is not participating. Either way, the warranty pays to repair a defect after it shows up. It does not pay for the ceiling that got wet before the duct leak was found, the month you spent arguing about it, or anything discovered after the coverage window closes. An inspector finds the item while it is still the builder's problem and still cheap.
Who should skip the inspection?
Almost nobody, but two cases come up. If you are buying a quick move in home that is already finished, skip pre-drywall because it is too late, and spend the money on a thorough final with thermal imaging instead. And if you are buying a condo where the association owns the structure, the pre-drywall visit matters less than a careful final on the unit itself and a read of the condo documents.
If a sales office visit at South Lake, Millersville Run or any other Maryland community is on your calendar, register us as your agent first. Half of the commission the builder pays us comes back to you at closing, which on most townhomes pays for every inspection on this page with money to spare, and we walk the final with you. The rest of the process is in how buying new construction works in Maryland.
