Pre Drywall Inspection Checklist: Catching Last Deficiencies

Written by Ed Caldeira | Nov 20, 2025 4:15:00 PM

Many causes of home warranty issues cannot be seen during the closing process because they are hidden behind drywall. A pre-drywall inspection (example) is the last opportunity to catch deficiencies before they cause problems months in the future.

Use this comprehensive pre drywall inspection checklist to ensure your build is on track and compliant with building codes, energy efficiency standards, and quality expectations.

Why a Pre Drywall Inspection Matters

A pre drywall inspection ensures everything inside your walls is correctly installed, code-compliant, and defect-free before it gets sealed up. Inspections at this stage typically cover:

  • Structural framing
  • HVAC system placement
  • Electrical wiring and outlet box positioning
  • Plumbing lines and pressure tests
  • Fire blocking and safety features
  • Insulation preparation

Missed defects at this point can lead to costly rework, failed inspections, delays, or unhappy homeowners.

Pro Tip: Use a Digital Checklist for Accuracy and Accountability

Paper checklists are easy to overlook. Using a digital inspection platform like FTQ360 helps ensure inspections are complete, photos are captured, and issues are resolved before drywall is installed. Teams can track deficiencies in real-time and improve accountability.

Frequently Asked Questions About Pre Drywall Inspections

What is a pre drywall inspection?

A pre drywall inspection is a critical quality control step during the home construction process. It occurs after framing, plumbing, electrical, HVAC, and other systems are installed but before insulation and drywall are added. The purpose is to verify that all components inside the walls are properly installed, up to code, and free of defects before they’re sealed in.

What should be on a pre drywall inspection checklist?

A comprehensive pre drywall inspection checklist should include items from all major trades, such as:

  • Framing alignment and fire blocking
  • Electrical wiring, boxes, and panel setup
  • Plumbing lines, venting, and pressure tests
  • HVAC duct routing and sealing
  • Window and door installation
  • Fire safety and air sealing
  • Exterior penetrations and waterproofing

Each item should be visually inspected and documented to ensure compliance and catch potential issues early.

When should a pre drywall inspection be done?

A pre drywall inspection should be conducted after rough-ins are completed (framing, plumbing, HVAC, and electrical), but before insulation and drywall are installed. This timing allows access to all wall cavities, systems, and structural components for a thorough visual and documented inspection.

Who should perform a pre drywall inspection?

  • A pre drywall inspection is typically performed by:
  • Local building inspectors (as part of required code compliance)
  • The general contractor or builder
  • A third-party home inspector (often hired by the buyer)
  • A quality assurance team, especially in production or custom homebuilding

Some builders also use construction inspection software to standardize and document inspections digitally for better accuracy and accountability.
