Understanding Pre-Drywall Inspections and Why They Matter
A pre-drywall inspection is your only real chance to see what’s behind the walls of a new home before drywall installation covers it all up. Once the walls close, the electrical wiring, plumbing system, HVAC systems, and insulation are hidden. Any potential problems at that point become far more costly to find and fix.
For buyers building in Jacksonville, here’s what a home inspector looks for during this crucial step, what they typically find, and why it matters.
What Is a Pre-Drywall Inspection?
A pre-drywall inspection is a visual evaluation of a new home’s systems after rough-in electrical work, plumbing, and HVAC installation are done, but before drywall goes up. It takes place during a specific window in the home building process, after the builder has installed the major systems and the house has passed municipal building codes inspections, but before anything is covered up.
That window is crucial. It’s the one point where every stud, joist, pipe, wire, and duct is fully visible and accessible for inspection.
What Will the Home Inspector Look For?
The home inspector evaluates the quality of work across several major areas of the house, checking that everything is installed correctly and meets building codes.
Here’s a real example from a recent Jacksonville inspection.
A crew was drilling a hole for a pipe and accidentally punched through the HVAC ductwork underneath the floor. Instead of reporting it, they shoved the broken pieces back in and moved on. Without an independent inspector catching it, that damage would have been sealed behind the walls with no one the wiser.
That’s just one example. Here’s a closer look at the major areas your inspector will evaluate and what they’re checking for.
Structural Components
The inspector checks that framing is square, plumb, and built according to plans.
Common concerns include bowed or improperly spaced studs, missing headers above doors and windows, and improperly secured joist hangers that compromise structural integrity.
Electrical Work and Outlets
The electrical system is checked for safe routing, correct junction box placement, and code compliance. Electrical outlets, switches, and dedicated circuits for appliances should match the plans and be positioned where they’ll be useful once the walls close.
Improperly routed electrical work is one of the most common safety concerns found at this stage.
Plumbing System
The plumbing system is inspected for proper routing, secure connections, and correct pipe sizing. The inspector looks for potential problems like pipes run through structural members without reinforcement and drain lines with incorrect slope. These are the types of issues that lead to leaks and costly repairs in the future if not corrected now.
HVAC Systems
Heating and air conditioning ductwork is checked for proper sizing, secure connections, and adequate support. Poorly installed HVAC systems can lead to energy loss, uneven temperatures throughout the house, and noise issues that are nearly impossible to fix after drywall installation.
Insulation and Environmental Factors
The inspector checks insulation for proper coverage, correct material, and no gaps. In Jacksonville’s hot, humid climate, environmental factors make proper insulation and vapor barrier installation crucial for energy efficiency, moisture management, and the long-term safety of the structure.

Why Aren’t Municipal or Builder Inspections Enough?
Many buyers assume that between county inspections and the builder’s own walkthroughs, everything is good. But municipal inspections, builder self-checks, and an independent pre-drywall inspection all serve very different purposes.
County inspectors focus on compliance with building codes at a minimum standard and often spend just 15 to 30 minutes on a property. Builder walkthroughs are helpful, but they’re the same team responsible for the work. That’s not an independent evaluation, and the builder’s priorities don’t always align with yours as the homeowner.
A pre-drywall inspection from an independent inspector typically lasts one to two hours, and results in a detailed inspection report focused entirely on your house and your concerns.

An independent inspector’s evaluation is a best practice in new home builds, even if your builder pushes back. The detailed inspection report gives homeowners real documentation to reference with the builder and any contractor involved in correcting issues.
Common Issues Found During a Pre-Drywall Inspection
Even with reputable builders, a drywall inspection at this stage routinely uncovers concerns. Dozens of contractors work on tight timelines, and mistakes happen. Catching problems early is the whole point.
Common findings include:
- Missing fire blocking between floors (a crucial safety concern)
- Electrical outlets at incorrect locations or heights
- Plumbing vents not routed to code
- HVAC ducts disconnected, poorly sealed, or undersized
- Improperly installed window flashing around doors and windows
- Insulation gaps around outlets, pipes, or at corners of exterior walls
- Flooring and floor level concerns from uneven framing
Most of these are straightforward to correct at the pre-drywall stage. After drywall installation, the same repairs require cutting into finished walls, costing more money and time. Fixing these issues at the pre-drywall stage costs a fraction of what the same repairs would run after the walls are closed.
Where This Inspection Fits in the New Home Building Process
If you’re building a new home in Jacksonville, a pre-drywall inspection is the second of three key inspection points.
- Pre-slab inspection takes place before they pour the concrete slab. This is your chance to verify plumbing rough-ins, post-tension cables, and soil preparation before they’re sealed under concrete.
- Pre-drywall inspection happens after rough-in work on the house is done. This is your widest window for inspecting the home’s structural and mechanical systems before closing up the walls.
- Final inspection takes place when the new home is finished, before your walkthrough with the builder. It covers everything from the roof to the foundation, including finished systems, flooring, doors, appliances, and surfaces.
Each inspection catches things the others can’t because each happens at a different stage when different elements are visible. Together, they give homeowners a complete picture of the work at every major milestone.
For Jacksonville buyers: New home construction is booming in areas like Nocatee, the Northside, St. Johns County, and along the First Coast Expressway corridor.
Builders and contractors are working at high volume, and that pace makes an independent inspector at each stage even more important for your peace of mind and the safety of your future home.
Other Questions New Home Buyers Ask
What is a pre-slab inspection?
A pre-slab inspection evaluates plumbing rough-ins, post-tension cables, and soil preparation before the concrete slab is poured. Once the slab is down, everything underneath is sealed permanently.
What does a final inspection cover?
The final inspection happens when the house is done, before your builder’s walkthrough. It evaluates every finished system and surface from the roof to the foundation.
Do new homes come with warranties?
Most builders offer a one-year workmanship warranty and longer structural warranties. Having a detailed inspection report from each stage strengthens your position if you need to file a claim in the future.
Should I get a home inspection even on new construction?
Yes. New doesn’t mean flawless. Dozens of contractors work on tight schedules, and mistakes happen. An independent home inspector catches what builder quality checks and municipal code inspections may not.
When to Schedule a Pre-Drywall Inspection
A qualified home inspector knows what to look for across electrical work, plumbing, HVAC systems, insulation, and safety concerns. This is not something homeowners can do effectively on their own, even with some building knowledge.
Book your inspection ASAP if:
- You’re building a new home and want independent verification of the work
- Rough-in work is done, and drywall hasn’t been hung yet
- You want a detailed inspection report to share with your builder
- You’re buying in a new development and want to confirm the work meets your standards, not just minimum code
Conclusion
A pre-drywall inspection is your best opportunity to verify that your new home is good to go. It’s the one point in the building process where the most critical systems are fully visible, and that window doesn’t stay open long. The peace of mind it provides is well worth the investment.
