A standard home inspection is performed in accordance with the InterNACHI® Home Inspection Standards of Practice (SOP) which can be found by clicking HERE. These standards establish the minimum requirements for a professional residential home inspection.
How a Standard InterNACHI® Home Inspection Works
A home inspection is a non-invasive, visual examination of the readily accessible areas of a residential property, performed for a fee, and designed to identify material defects within specific systems and components as defined by the InterNACHI® Standards of Practice.
A material defect is a condition that, in the judgment of the inspector, significantly affects the value of the property or poses an unreasonable risk to people.
In practical terms, during your inspection we will:
- Visually inspect readily accessible and safely reachable areas of the home
- Operate normal homeowner controls where appropriate
- Describe inspected systems and components in a written report
- Report observed material defects present at the time of the inspection
The inspection is not technically exhaustive and does not involve dismantling, destructive testing, or invasive procedures. It is not a code compliance inspection, engineering evaluation, or warranty. The inspection reflects the condition of the property at the time of the inspection, based solely on what is visible and accessible.
Systems Included in a Standard Home Inspection
At a minimum, the InterNACHI® Standards of Practice require inspection and reporting on the following systems:
- Roof
- Exterior
- Basement, foundation, crawlspace, and structure
- Heating
- Cooling
- Plumbing
- Electrical
- Fireplace
- Attic, insulation, and ventilation
- Doors, windows, and interior
Roof
The inspector shall inspect:
- Roof covering materials
- Visible flashings, penetrations, and skylights
- Gutters and downspouts
- Visible signs of leakage or damage
Exterior
The inspector shall inspect:
- Exterior wall coverings, trim, and flashing
- Exterior doors
- Decks, balconies, stoops, steps, and porches
- Driveways, walkways, and grading adjacent to the structure
- Attached garages and carports
Basement, Foundation, Crawlspace, and Structure
The inspector shall inspect:
- Visible foundation components
- Structural framing where accessible
- Crawlspaces and basements where accessible
- Visible signs of moisture intrusion, water penetration, or structural movement
Heating System
The inspector shall inspect:
- Accessible heating equipment
- Normal operating controls
- Visible distribution systems
- Visible venting and fuel supply where applicable
Cooling System
The inspector shall inspect:
- Central air conditioning or heat pump systems, if installed
- Normal operating controls
- Visible cooling equipment and components
Plumbing System
The inspector shall inspect:
- Interior water supply and distribution systems
- Drain, waste, and vent systems where visible
- Plumbing fixtures and faucets
- Water heating equipment
Electrical System
The inspector shall inspect:
- Service entrance conductors and service disconnect
- Main and sub panels
- A representative number of switches, receptacles, and lighting fixtures
- Presence of ground-fault and arc-fault protection where installed
Fireplaces and Fuel-Burning Appliances
The inspector shall inspect:
- Readily accessible fireplaces, inserts, and stoves
- Visible chimneys and venting systems
- Basic operation of accessible components where safe
Attic, Insulation, and Ventilation
The inspector shall inspect:
- Attic access and visible framing
- Insulation type and approximate depth
- Ventilation systems where accessible
- Visible signs of leaks, condensation, or moisture intrusion
Doors, Windows, and Interior
The inspector shall inspect:
- Interior walls, ceilings, and floors
- Steps, stairways, handrails, and guardrails
- Interior doors and a representative number of windows
- Built-in cabinets and countertops
- Smoke and carbon monoxide alarms where present
What Is Outside the Scope of a Standard Home Inspection
A standard home inspection does not include:
- Code compliance verification or permit review
- Engineering or architectural analysis
- Environmental testing such as radon, mold, asbestos, lead, or air quality
- Pest inspections requiring a separate license
- Wells, septic systems, irrigation systems, water treatment systems, or specialty equipment
- Pools, spas, or similar recreational features
- Thermal imaging, sewer scopes, or other ancillary services unless specifically contracted
- Predicting future performance, remaining service life, or guaranteeing hidden defects
Going Beyond the Minimum Standards
The InterNACHI® Standards of Practice represent a baseline. Many experienced inspectors choose to exceed these minimum requirements by providing additional detail, documentation, and explanations, while still operating within the limits of a visual, non-invasive inspection.
Your written report will:
- Identify inspected systems and components
- Describe observed material defects and safety concerns
- Provide recommendations for repair, further evaluation, or monitoring
