Top Common Home Inspection Defects Found in New Construction Final Inspections

When buying a newly built home, many expect everything to be perfect. After all, it’s brand new construction. Yet, final home inspections often reveal defects that can cause costly repairs or safety concerns down the line. Understanding the most common issues found during these inspections helps buyers prepare and negotiate effectively. This article highlights typical defects discovered in new construction final inspections and explains why they matter.

Structural and Foundation Issues

Even new homes can have structural problems. Inspectors frequently find cracks in foundations or uneven floors. These defects may indicate settling issues or poor soil preparation. For example, a visible crack wider than 1/4 inch in a foundation wall can allow water intrusion or compromise stability.

Other structural concerns include:

• Improperly installed support beams or joists

• Gaps between framing members

• Uneven or sloping floors

  
  

These problems affect the home’s long-term durability and may require costly repairs if left unaddressed.

Roofing and Exterior Defects

Roofing problems are common in new homes, often due to rushed installation or subpar materials. Inspectors look for:

• Missing or damaged shingles

• Poor flashing around chimneys, vents, and skylights

• Inadequate roof ventilation

  
  

Faulty roofing can lead to leaks, water damage, and mold growth inside the home. Exterior siding and trim may also show defects such as:

• Gaps or cracks in siding panels

• Improper sealing around windows and doors

• Paint or finish issues

  
  

These defects allow moisture penetration and reduce energy efficiency.

Plumbing and Electrical Problems

New construction plumbing systems sometimes have leaks or improper connections. Common issues include:

• Loose or leaking pipe fittings

• Incorrect water pressure

• Poorly installed fixtures

  
  

Electrical defects are also frequent, such as:

• Exposed wiring or loose connections

• Non-functional outlets or switches

• Improper grounding or circuit breaker issues

  
  

These problems pose safety hazards and may require licensed professionals to fix.

HVAC System Deficiencies

Heating, ventilation, and air conditioning (HVAC) systems in new homes often have installation errors. Inspectors may find:

• Incorrect duct sizing or placement

• Poor sealing of duct joints causing air leaks

• Thermostat malfunctions

  
  

These defects reduce system efficiency and increase energy costs. Proper HVAC installation is critical for comfort and indoor air quality.

Interior Finishes and Fixtures

Final inspections often reveal cosmetic and functional defects inside the home. Examples include:

• Misaligned doors and windows that don’t close properly

• Cracked or uneven drywall

• Paint drips or missed spots

• Loose or missing hardware on cabinets and drawers

  
  

While these issues may seem minor, they affect the home’s appearance and usability.

Safety Concerns

Safety defects are especially important to catch before closing on a new home. Inspectors check for:

• Missing or improperly installed smoke and carbon monoxide detectors

• Inadequate stair railings or guardrails

• Trip hazards from uneven flooring or thresholds

• Improperly installed handrails or balusters

  
  

Addressing these concerns protects occupants and ensures code compliance.

Why These Defects Occur in New Construction

New homes are complex projects involving many trades and tight schedules. Common causes of defects include:

• Rushed work to meet deadlines

• Lack of proper supervision or quality control

• Use of inexperienced subcontractors

• Material defects or damage during construction

  
  

Buyers should expect some issues but use inspections to identify and fix them before moving in.

What Buyers Should Do

To avoid surprises, buyers should:

• Hire a qualified, independent home inspector experienced with new construction

• Attend the inspection to ask questions and see defects firsthand

• Request detailed reports with photos and recommendations

• Negotiate repairs or credits with the builder before closing

• Schedule a follow-up inspection after repairs

  
  

Being proactive helps ensure the new home is safe, sound, and comfortable.
