InterNACHI Standards of Practice Overview:
The InterNACHI Standards of Practice set a high bar for home inspections, providing a comprehensive blueprint for evaluating a home’s condition. These standards are designed to ensure that inspectors thoroughly examine all significant systems and structural components of a property, from the roof down to the foundation. Here’s an expanded look at what these standards entail:
- Roof: Inspectors check the condition of roof coverings, the integrity of gutters and downspouts, and the installation of vents, flashing, skylights, and chimneys. They assess the roof’s structure for any visible signs of damage or wear from accessible vantage points.
- Exterior: This includes evaluating the condition of siding, trim, doors, windows, and any attached structures like decks or porches. Inspectors also look at how vegetation, drainage, and grading might impact the home’s exterior.
- Basement, Foundation, Crawlspace & Structure: Examination focuses on the foundation’s condition, looking for signs of water intrusion, structural integrity, and the adequacy of support systems like beams and columns.
- Heating: The heating system is operated to assess functionality, including checking the distribution system and the condition of vents, flues, and chimneys, ensuring they’re free from hazards.
- Cooling: Similar to heating, the cooling system’s operation is tested, with attention to distribution systems and condensate management to prevent moisture issues.
- Plumbing: Inspectors review all visible plumbing for leaks, corrosion, and proper function, including water supply, drainage, fixtures, and water heating equipment.
- Electrical: This involves evaluating the electrical service, main disconnects, grounding, panelboards, and a representative number of outlets, switches, and fixtures to ensure safety and functionality.
- Fireplace: Checking the condition of the hearth, damper, flue, and chimney for safety and operational integrity.
- Attic, Insulation & Ventilation: Inspectors assess insulation levels in accessible areas, check for proper ventilation to prevent moisture buildup, and ensure mechanical ventilation systems are working.
- Doors, Windows & Interior: A sample of doors and windows are tested for operation, walls, ceilings, and floors are inspected for signs of damage or structural issues, and stairways and railings are evaluated for safety.
Exclusions under these standards include anything not permanently installed, systems that are shut down or inaccessible, and low-voltage systems unless specifically agreed upon.

Additional Notes:
- General Exclusions: The inspector is not required to operate systems that are shut down, dismantle equipment, or enter areas that are not readily accessible or could be unsafe. Also, items not permanently installed and low-voltage electrical systems (like security systems, phone lines, etc.) are generally not inspected unless specified.
- Inspection Scope: The inspection is visual and non-invasive, based on what can be observed on the day of the inspection without moving personal items, furniture, or making any destructive changes.
