New-construction homes get sold with the implicit assumption that everything is right because everything is new. That assumption breaks down in practice. National survey data from inspection trade groups consistently shows that new-construction inspections turn up defects on most properties — sometimes minor cosmetic items, sometimes substantive code or workmanship issues. A new construction home inspection checklist PDF, used as both a buyer’s reference document and a working field list, gives the buyer a structured way to engage with the property before the warranty clock runs out. This guide covers what such a checklist should include, where buyers can find PDF templates, and how a new-construction inspection differs from a resale inspection.

New construction home inspection checklist PDF: what it should cover

A useful new-construction inspection checklist covers four categories that map to the typical buyer touchpoints with the property:

1. Pre-drywall (rough-in) inspection

Performed after framing, plumbing rough, electrical rough, and HVAC rough are complete but before insulation and drywall close the walls. This is the only window to see how the house is actually built.

• Framing — proper nailing, joist spacing, beam sizing, header construction
• Plumbing rough — supply line sizing, drain slopes, venting, water hammer arrestors
• Electrical rough — wire sizing, junction boxes, GFCI and AFCI locations, panel sizing
• HVAC rough — duct sizing, register locations, return path adequacy
• Insulation — verify R-values match plans before drywall closes
• Air sealing — penetrations sealed before insulation

2. Final walkthrough inspection

Performed when the builder declares the house complete and ready for closing. This is the inspection most buyers think of as “the new construction inspection.”

• Exterior — siding alignment, trim caulking, paint coverage, grade and drainage
• Roof — shingle alignment, flashing, ridge vents, gutter installation
• Windows and doors — operation, weatherstripping, gaps and racking
• Interior finishes — drywall texture, paint coverage, cabinet alignment, flooring
• Plumbing fixtures — function, drainage, supply pressure, hot water response
• Electrical — outlets, GFCI/AFCI function, switch operation, fixture installation
• HVAC commissioning — heating and cooling operation, register airflow, thermostat function
• Appliances — power-on test, function check
• Code-required exhausts — bath fans, range hood, dryer venting

3. Builder warranty inspection (11-month)

Most builders provide a one-year fit-and-finish warranty. An inspection at 11 months catches issues that have emerged during the first year of occupancy before the warranty expires.

• Settlement cracks in drywall and stucco
• HVAC performance during full heating and cooling seasons
• Plumbing leaks that have developed
• Door and window operation after seasonal movement
• Roof performance through a full year of weather
• Grade and drainage performance after weather events
• Appliance function after extended use

4. Long-term warranty items (2-10 year)

Major systems warranties run longer than fit-and-finish. Track these for the duration of coverage:

• HVAC system warranty (typically 5-10 years on major components)
• Roof material warranty (20-50 years prorated, with installation warranty 1-10 years)
• Structural warranty (typically 10 years per state law in many states)
• Major appliance manufacturer warranties

What makes new-construction inspection different from resale inspection

Code compliance focus

New construction is built to current IRC and local amendments. A new construction inspector specifically checks code compliance items that a resale inspector might note but not emphasize. GFCI placement, AFCI breaker presence, smoke and CO detector locations, egress dimensions, stair geometry, handrail and guardrail requirements.

Builder warranty as recourse

Resale inspections inform negotiation; new construction inspections create a documented record of issues that the builder is contractually obligated to address under the warranty. Documentation discipline matters more in new construction because the recourse path runs through the builder for the first year and beyond.

Workmanship vs aging

Resale inspections distinguish original construction quality from age-related wear. New construction inspections are looking only at workmanship — there is no aging contribution to the findings.

Builder walkthrough vs independent inspection

Builders typically conduct their own walkthrough before closing. This is not equivalent to an independent inspection. The builder’s interest is closing the sale; the inspector’s interest is identifying defects. Most experienced buyers hire an independent inspector in addition to the builder walkthrough.

The companion guides on new home inspector career considerations and home inspection checklist PDF formats cover adjacent topics.

Common new-construction defects to flag

Trade publications and inspection trade groups consistently identify the following as the most common new-construction findings:

Drywall texture and paint touchup

Inconsistent texture, missed paint spots, and drywall finish defects (banding, ridges, fastener pops) are the highest-volume findings. Most are cosmetic and addressable under warranty.

Cabinet alignment

Doors out of plumb, drawers binding, hardware missing or loose. Builder warranty items.

HVAC commissioning

Systems not balanced, registers blowing wrong direction, thermostats wired incorrectly, condensate lines not connected. Significant items that affect comfort and efficiency.

Code-required exhausts

Bath fans terminated in attic instead of through roof, dryer vents that exceed allowed length, range hood vents non-functional. Common findings with real consequences for mold, fire, and indoor air quality.

Plumbing fixtures

Slow drains from construction debris, supply leaks at fixture connections, P-traps installed incorrectly. Builder warranty items but worth catching at walkthrough.

Electrical

Outlets reverse-polarity, GFCI not at code-required locations, AFCI breakers absent on bedroom circuits, missing arc-fault protection on required circuits. Code-compliance items.

Exterior

Grading sloped toward foundation instead of away, gutters undersized, downspouts terminating at the foundation, missing flashing at penetrations.

Insulation

Compressed batt sections, missing pieces in inaccessible corners, attic insulation depth less than specified. Energy efficiency and comfort items.

Timing the inspection within the build

The pre-drywall inspection has to happen at the right moment in the build. Schedule it when:

• Framing inspection has been signed off by the local building department
• Rough plumbing, electrical, and HVAC are all complete
• The builder is preparing to call for insulation inspection
• Before insulation is installed

Missing this window means giving up the opportunity to see how the house is built. Most builders will accommodate the inspection if asked in advance; some resist. Resistance is a red flag.

What an independent new-construction inspector costs

Typical fee ranges in 2026:

• Pre-drywall inspection: $300–$600
• Final walkthrough inspection: $400–$700
• 11-month warranty inspection: $400–$700
• Combined package (all three): $1,000–$1,800

Pricing varies by region and home size. For a $500,000+ new home, the inspection investment is well under 1% of purchase price and routinely identifies thousands in warranty-claimable findings.

Working with the builder after the inspection

Process matters. The inspection report should be:

• Submitted to the builder in writing
• Acknowledged with a written response
• Items prioritized by category (safety, code, workmanship, cosmetic)
• Resolution timeline agreed in writing
• Documentation kept for the warranty period

Builders vary widely in how they handle warranty work. Reputable builders respond constructively to documented findings. Less-reputable builders push back on items as “normal” that an independent inspector has flagged as defects. Knowing which side of that line your builder falls on before closing matters.

Code compliance references

Several authoritative resources govern what counts as a code defect:

• International Residential Code (IRC) — the baseline for most residential construction in the U.S.
• Local amendments — most jurisdictions adopt IRC with modifications
• National Electrical Code (NEC) — electrical requirements
• International Plumbing Code or Uniform Plumbing Code — plumbing requirements depending on jurisdiction
• International Mechanical Code — HVAC requirements

An inspector should reference the specific code section for any code-compliance finding. This makes the warranty conversation with the builder concrete rather than subjective. See the broader hiring context at hiring a home inspector pillar and the cluster guide on home inspection checklist templates.

When to call a professional

For new construction, an independent inspector is the default recommendation regardless of how reputable the builder is. The cost is modest relative to the home price, and the inspector’s findings provide both pre-closing leverage and a documented baseline for warranty claims through the first year and beyond. Buyers who skip independent inspection of new construction routinely find themselves discovering issues during the second year of occupancy with no warranty recourse.

• Thermostat operation and wiring
• Condensate drain installation and termination
• Equipment access and service clearances
• Filter access and proper sizing

How to organize the inspection day

A typical full new-construction final walkthrough takes three to four hours. Effective organization:

• Start exterior; capture grading, drainage, and siding while morning lighting is good
• Move to roof access if safe and within scope; document with drone or camera
• Enter the home, working room by room with a consistent pattern
• Check mechanical room and utility spaces
• Test HVAC operation requiring 10–15 minutes settled run time
• Test plumbing fixtures with simultaneous-use scenarios
• Cycle electrical outlets and switches
• Document any code or workmanship concerns with photos and code references
• Brief the buyer at the end of the inspection on key findings

Photography is critical. Every finding should have at least one photograph; serious findings should have multiple angles and contextual photos showing location within the home.

Working with the builder warranty process

Most builders use a structured warranty process:

• Punch list at final walkthrough — items the builder commits to address before closing
• 30-day call-back list — items emerged in the first month
• 11-month call-back list — final warranty inspection items
• Major systems warranties extend longer (HVAC, structural, roof)

Buyers should know the timeline and document concerns within each window. The cluster guides on home inspection checklist PDF formats and home inspector checklist workflow cover related material. For the hiring side, see the hiring a home inspector pillar.

Common builder pushback and how to respond

Builders sometimes deflect findings with standard responses. Effective counter-arguments:

“That’s normal settlement”

Some settlement is expected but visible drywall cracks in the first year often indicate framing or foundation issues that warrant investigation, not blanket dismissal.

“That’s industry-standard finish”

Cite specific industry standards. NAHB and IRC have specific tolerances for drywall finish, framing alignment, and other workmanship criteria.

“The code official signed off”

Code sign-off is a minimum compliance threshold, not a quality benchmark. Items below code standards are defects regardless of sign-off; items meeting code can still be quality concerns.

“You’re being too picky”

Document findings with photos and code references. Reasonable findings backed by documentation are harder to dismiss.

State-specific considerations

State law affects new-construction inspection in several ways:

• Mandatory disclosure requirements vary
• Builder warranty durations vary; some states mandate longer structural coverage
• Right-to-repair laws may require buyer notification before legal action
• Statutes of limitation on defect claims vary widely
• Some states require licensing for new construction inspectors specifically

Buyers should know their state’s framework before the inspection. A real estate attorney can clarify state-specific protections.

Why a single inspection is rarely enough

Many issues emerge over the first year of occupancy as systems cycle through full seasons:

• HVAC performance reveals itself across summer and winter extremes
• Plumbing leaks often emerge from continued cycling
• Settlement cracks appear as the structure equilibrates
• Grading performance shows under heavy rain or snow melt
• Roof performance manifests under wind, hail, and freeze-thaw cycles

The 11-month warranty inspection catches these emergent issues before the fit-and-finish warranty expires. Skipping this inspection forfeits the leverage of warranty coverage.
