The Ultimate Checklist for New Construction Home Inspections

Buying a newly built home is exciting, but fresh paint and new finishes do not always mean every detail is complete. Small installation mistakes, loose fixtures, drainage issues, plumbing leaks, or unfinished work can still be present.

A professional new home inspection gives buyers a detailed look at the accessible systems and components before they take ownership.

The best way to approach the inspection is with a clear checklist. Rather than focusing only on cosmetic details, buyers should pay attention to the roof, exterior drainage, electrical system, plumbing, HVAC equipment, insulation, windows, doors, appliances, and safety features.

Use this practical house inspection checklist to understand the areas that deserve attention in a newly constructed home.

Exterior and Building Envelope Checklist

Start with the outside of the home.

The exterior protects the interior from rain, wind, sunlight, and changing temperatures. Small gaps or incomplete finishes can create maintenance problems later.

Check for:

• Cracks in stucco or siding
• Damaged exterior finishes
• Loose trim
• Missing sealant
• Gaps around pipes and wall penetrations
• Damage around windows and doors
• Incomplete paint
• Loose exterior fixtures
• Cracked walkways
• Damaged patios or porches

Pay particular attention to places where two different materials meet.

For example, the area around windows, doors, utility penetrations, and exterior trim often depends on proper flashing or sealant to help manage water.

A new construction home inspection should document visible areas that appear damaged, incomplete, or poorly sealed.

Grading and Drainage Checklist

Good drainage helps move water away from the house.

A newly landscaped yard may look attractive, but the shape of the ground can affect how rain and irrigation water move around the property.

Inspect:

• Soil slope around the foundation
• Low areas near exterior walls
• Downspout discharge points
• Drainage channels
• Yard drains
• Areas where water may collect
• Signs of erosion
• Irrigation near the home
• Walkways that direct water toward the building

Water should generally move away from the structure.

A low area beside the foundation can hold water during heavy rain or irrigation. Even if the soil is dry on inspection day, visible grading can help identify areas worth watching.

For Southern California homes, drainage still matters even though long dry periods are common.

Roof Checklist

New roofing materials can still have installation or construction-related defects.

An inspector may review the roof from a safe and accessible location and look for:

• Damaged roofing materials
• Loose materials
• Missing components
• Flashing concerns
• Roof penetrations
• Vents
• Skylights
• Chimney components when present
• Gutters
• Downspouts
• Drainage
• Construction debris

Roof penetrations deserve extra attention.

Plumbing vents, exhaust vents, skylights, and other openings need proper flashing and sealing to help prevent water intrusion.

A new construction inspection should also consider whether roof drainage appears to move water away from vulnerable parts of the home.

Attic and Insulation Checklist

The attic can reveal details that are hidden from the finished rooms below.

When safely accessible, check:

• Roof framing
• Roof sheathing
• Insulation coverage
• Ventilation
• HVAC ducts
• Electrical wiring
• Plumbing penetrations
• Exhaust ducts
• Moisture staining
• Construction debris

Insulation should appear reasonably consistent.

Missing, compressed, or disturbed insulation may affect comfort and energy efficiency.

Bathroom exhaust ducts also deserve attention. Moist air from bathrooms should not simply be released into the attic.

The attic portion of a new home inspection can help identify workmanship issues that buyers would not normally notice during a regular walkthrough.

Foundation and Visible Structural Checklist

A new home's visible structural components should still be reviewed carefully.

Check for:

• Significant foundation cracks
• Unusual separation
• Floor movement
• Framing concerns
• Visible support problems
• Wall alignment
• Stair construction
• Loose railings
• Damaged structural materials

A small crack does not automatically mean there is a serious structural problem.

Concrete and finished materials can crack for several reasons. The inspector considers the location, size, pattern, and surrounding conditions before recommending further evaluation.

If significant structural concerns are observed, an engineer or another qualified specialist may be recommended.

Electrical System Checklist

Electrical components should be checked throughout the house.

A professional inspector may review accessible:

• Main electrical panel
• Circuit breakers
• Panel labeling
• Outlets
• Switches
• Light fixtures
• GFCI protection
• AFCI protection
• Visible wiring
• Grounding
• Bonding
• Exterior outlets

Common issues in a newly built property may include:

• Outlets that do not operate
• Loose switches
• Missing covers
• Lights that do not respond properly
• Incorrect panel labels
• Loose fixtures

GFCI protection is especially important in areas such as bathrooms, kitchens, garages, and exterior locations where required.

The electrical portion of the house inspection checklist should focus on operation, visible installation, and safety-related concerns.

Plumbing Checklist

New plumbing connections should not be assumed to be leak-free.

Check:

• Faucets
• Toilets
• Sinks
• Bathtubs
• Showers
• Water pressure
• Drainage
• Hot and cold water
• Visible supply pipes
• Accessible drain pipes
• Exterior hose connections
• Water heater connections

Run water at fixtures and look beneath sinks for signs of leakage.

Check whether:

• Faucets operate smoothly
• Toilets flush correctly
• Water drains normally
• Hot and cold water are connected properly
• Cabinets remain dry beneath plumbing fixtures

Even a small leak can damage new cabinetry, drywall, flooring, or other materials if it continues unnoticed.

Water Heater Checklist

The water heater should also be reviewed as part of the new construction home inspection.

Depending on the system, inspect accessible:

• Water connections
• Drainage
• Temperature and pressure relief components
• Venting
• Electrical or gas connections
• Mounting
• Visible leaks
• Nearby moisture damage

The exact components depend on whether the home has a tank, tankless, gas, or electric system.

A new unit can still have installation concerns, so age alone should not be used to judge condition.

HVAC Checklist

Heating, cooling, and ventilation affect comfort throughout the home.

When conditions allow, check:

• Heating operation
• Cooling operation
• Thermostat response
• Supply vents
• Return vents
• Visible ductwork
• Airflow
• Condensate drainage
• Exterior HVAC equipment
• Filters
• Exhaust ventilation

Walk through several rooms while the system operates.

One room with noticeably weak airflow may indicate a duct, balancing, or installation concern.

Visible duct connections in accessible areas should also be reviewed.

A new home inspection should help identify obvious operational or installation problems, but detailed mechanical diagnosis may require an HVAC specialist.

Kitchen Checklist

The kitchen combines plumbing, electrical systems, appliances, ventilation, cabinetry, and finished surfaces.

Check:

• Sink operation
• Faucet
• Drainage
• Plumbing connections
• Garbage disposal
• Electrical outlets
• GFCI protection
• Lighting
• Exhaust ventilation
• Cabinets
• Drawers
• Countertops
• Flooring
• Built-in appliances
• Sealant

Open cabinets and drawers.

Look under the sink while water is running.

Watch for:

• Leaks
• Loose hardware
• Poor cabinet alignment
• Damaged countertops
• Missing sealant
• Electrical outlets that do not work

A detailed checklist helps buyers move beyond the appearance of a new kitchen and evaluate how the installed components actually function.

Bathroom Checklist

Bathrooms deserve careful attention because they combine moisture, plumbing, electricity, and ventilation.

Check each bathroom for:

• Sink operation
• Faucet function
• Toilet operation
• Shower drainage
• Tub drainage
• Visible plumbing leaks
• Exhaust fan operation
• GFCI-protected outlets
• Shower enclosure
• Caulking
• Grout
• Cabinets
• Flooring
• Doors
• Windows when present

Inspect the areas around tubs and showers for incomplete sealant or visible gaps.

Small finishing issues can become moisture problems after regular use begins.

Bathroom exhaust fans should also operate properly and move moist air away from the room.

Windows and Doors Checklist

Doors and windows should open, close, lock, and latch normally.

Check:

• Exterior doors
• Interior doors
• Sliding doors
• Windows
• Locks
• Latches
• Handles
• Weather stripping
• Screens when included
• Visible sealant
• Door alignment
• Window alignment

A door that rubs slightly may only need adjustment, but it should still be documented.

Windows should move as intended and remain secure.

Also look for gaps around exterior frames that may allow air or moisture intrusion.

Walls, Ceilings, and Flooring Checklist

Fresh finishes can make small defects easy to overlook.

Walk through each room and check:

• Drywall cracks
• Ceiling cracks
• Paint defects
• Damaged trim
• Uneven flooring
• Loose flooring
• Cracked tile
• Ceiling stains
• Gaps
• Missing finish work
• Construction damage

The goal is not to expect every surface to be visually perfect.

Instead, document noticeable conditions and separate cosmetic items from defects involving moisture, movement, or installation.

This section of the house inspection checklist can also help buyers create a clearer list of finishing concerns to discuss with the builder.

Cabinets, Countertops, and Built-In Features Checklist

Inspect built-in features for proper operation and visible damage.

Check:

• Cabinet doors
• Drawers
• Shelving
• Countertops
• Bathroom vanities
• Closet shelving
• Baseboards
• Interior trim
• Hardware

Look for:

• Loose components
• Missing hardware
• Poor alignment
• Damaged finishes
• Gaps
• Incomplete installation

These items may not be major building defects, but documenting them before move-in can prevent confusion later.

Built-In Appliance Checklist

If built-in appliances are installed and included in the inspection scope, they may be operated using normal controls.

Check:

• Oven
• Cooktop
• Dishwasher
• Built-in microwave
• Garbage disposal
• Range hood

The inspector may confirm basic operation and visible installation.

A new construction inspection does not predict the future life of an appliance, but it can identify obvious problems present at the time of inspection.

Buyers should also keep manufacturer warranties and manuals with their home records.

Garage Checklist

Do not overlook the garage.

Check:

• Garage door operation
• Garage door opener
• Safety-reversal features
• Walls
• Ceiling
• Flooring
• Electrical outlets
• Lighting
• Door between the garage and home
• Visible plumbing
• Mechanical equipment

Look for loose hardware, damaged finishes, incomplete construction, or components that do not operate correctly.

The garage often contains electrical, plumbing, HVAC, or water-heating equipment, so it can reveal more than cosmetic issues.

Smoke, Carbon Monoxide, and Safety Checklist

Safety components should be reviewed before move-in.

Check accessible:

• Smoke alarms
• Carbon monoxide alarms
• Handrails
• Guardrails
• Stairways
• Exterior steps
• Egress openings
• Garage safety features

Railings should feel secure.

Stairs should not have obvious loose or damaged components.

Installed alarms should be present and tested within the inspection scope.

These items may seem simple, but they can have an immediate effect on household safety.

What to Look for in the Home Inspection Report

A good home inspection report should make the findings easy to understand.

Look for:

• Clear descriptions
• Locations of defects
• Photographs when useful
• Recommendations
• Areas that could not be inspected
• Items needing specialist evaluation

Do not judge the property only by the number of findings.

Ten small cosmetic items may be less important than one active plumbing leak or electrical safety concern.

A useful report helps buyers understand which findings deserve attention first.

Use a Complete Checklist Before Taking Ownership

A newly built home should be evaluated as a complete property, not simply by how fresh the finishes appear.

Roofing, drainage, electrical systems, plumbing, HVAC equipment, insulation, windows, doors, appliances, interior finishes, and safety features all deserve attention.

A detailed new home inspection can help identify visible defects, unfinished work, and installation concerns before they become harder to address.
