Essential Guide to New Construction Inspections: Understanding the 4 Key Phases

Building a new home is an exciting journey, but it also comes with many critical steps to ensure the final product is safe, sound, and built to last. One of the most important parts of this process is new construction inspections. These inspections happen in phases, each focusing on different aspects of the build. Knowing what happens at each phase helps homeowners and builders catch issues early, avoid costly repairs, and ensure quality.

This guide breaks down the four key phases of new construction inspections: pre-pour/foundation, pre-drywall/framing, completion/final, and the 11-month warranty inspection. Understanding what inspectors look for at each stage will give you confidence throughout your home-building experience.

Pre-pour foundation inspection on a new construction site

Pre-pour foundation inspection ensures the base of the home is solid and ready for concrete.

Pre-pour/Foundation Inspection

The first major inspection happens before the concrete is poured for the foundation. This phase is crucial because the foundation supports the entire structure. Inspectors check:

• Soil condition and compaction to ensure it can support the weight of the house.

• Footings and forms to confirm they are the correct size and properly placed.

• Rebar placement to verify steel reinforcement is installed according to plans.

• Drainage and waterproofing measures to prevent future water damage.

  
  

Why this matters: If the foundation is flawed, it can lead to cracks, settling, or even structural failure. Catching problems before pouring concrete saves time and money. A thorough pre-pour/foundation inspection gives peace of mind that the home’s base is strong.

Pre-drywall/Framing Inspection

Once the foundation is set and framing is up, the next inspection takes place before drywall installation. This phase is often called the pre-drywall inspection or framing inspection. Inspectors focus on:

• Structural framing including walls, floors, and roof trusses.

• Electrical wiring and plumbing rough-ins to ensure they meet code and are correctly installed.

• HVAC ductwork placement and sealing.

• Insulation preparation and vapor barriers.

  
  

This inspection is important because it checks the home’s skeleton and internal systems before they get covered up. Fixing issues at this stage is easier and less expensive than after drywall goes up. For example, if wiring is not up to code, the inspector will flag it so the builder can correct it before finishing the walls.

Completion/Final Walkthrough Inspection

The final walkthrough or completion inspection happens when the home is nearly finished. This inspection covers everything visible and functional, including:

• Doors and windows for proper installation and operation.

• Flooring, cabinetry, and fixtures for quality and finish.

• Electrical outlets, switches, and lighting to confirm they work safely.

• Plumbing fixtures for leaks and proper function.

• Heating and cooling systems for performance.

• Safety features such as smoke detectors and handrails.

  
  

This phase ensures the home is ready for occupancy and meets all building codes. The inspector’s report helps the homeowner identify any last-minute repairs or touch-ups before closing. It’s the final chance to catch defects and ensure the builder has met expectations.

11-Month Warranty Inspection

Most new homes come with a builder’s warranty that lasts about one year. The 11-month warranty inspection happens near the end of this period. It focuses on:

• Identifying defects or issues that have appeared since moving in.

• Checking for water intrusion, cracks, or settling.

• Testing mechanical systems like HVAC, plumbing, and electrical.

• Reviewing cosmetic problems such as paint or flooring damage.

  
  

This inspection is a homeowner’s opportunity to document problems covered under warranty. Builders typically fix these issues at no extra cost. Scheduling this inspection before the warranty expires protects your investment and ensures your new home remains in good condition.

Why Phased Inspections Matter

Each phase of new construction inspections plays a vital role in building a safe, durable home. Skipping or rushing any inspection can lead to hidden problems that become expensive repairs later. For example, missing a framing issue could cause structural weaknesses, while ignoring the 11-month warranty inspection might leave you responsible for costly fixes.

Working with a qualified inspector who understands the phases and what to look for helps homeowners and builders stay on track. It also builds trust and transparency throughout the construction process.

Building a new home is a major investment. Understanding the four key phases of phased inspection helps you protect that investment and avoid surprises. From the foundation to the final walkthrough and warranty check, each inspection ensures your home is built right.
