Home Inspection Glossary

---

Automatic safety controls are specifically designed devices that protect systems and components from unsafe conditions, a critical aspect of any building inspection glossary. In this context, a component refers to a part of a system. Decorative ornamental elements are not necessary for the proper operation of essential systems and components of a home, rendering them less relevant in home inspection terms. To effectively describe a system and its components, one identifies them in writing by their type or other distinguishing characteristics. Dismantling refers to the process of taking apart or removing components, devices, or pieces of equipment that a homeowner would not typically disassemble during normal maintenance. Engineering involves applying scientific knowledge for the design, control, or usage of building structures, equipment, or apparatus. Further evaluation encompasses examination and analysis performed by a qualified professional, tradesman, or service technician, extending beyond the basics of a standard home inspection. During a home inspection, an inspector visually examines readily accessible systems and components of a home, accurately describing those systems and components while adhering to a specific standard. Inspecting involves assessing these readily accessible systems by applying the standard, operating normal controls, and opening readily openable access panels. The inspector, hired to evaluate the systems and components of a building, uses this standard to ensure accuracy. Installed systems are those affixed such that removal requires tools, and normal operating controls include devices like thermostats, switches, and valves intended for homeowner operation. Readily accessible systems are those available for visual inspection without needing to move personal property, dismantle, or engage in any destructive measures that pose a risk to persons or property. A readily openable access panel is designed for homeowner inspection and maintenance, ensuring it is accessible, easily within reach, can be opened by one person, and is not sealed in place. Recreational facilities encompass spas, saunas, steam baths, swimming pools, exercise equipment, entertainment setups, athletic facilities, playgrounds, and similar accessories. When referring to a representative number, it means inspecting one component per room for multiple similar interior components like windows and electric receptacles, and one component on each side of the building for multiple similar exterior components. Roof drainage systems are responsible for carrying water off a roof and away from a building. A system may be in a shut down state when the components cannot be operated by normal controls. Structural components support both non-variable weights (dead loads) and variable weights (live loads). Essentially, a system is a combination of interacting or interdependent components assembled to perform one or more functions. A technically exhaustive investigation involves dismantling and extensively employing advanced techniques, measurements, instruments, and tests. The under-floor crawlspace is the area between the ground and the underside of the floor, within the confines of the foundation. An unsafe condition in a readily accessible installed system or component is one that poses a significant risk of serious bodily injury during normal, day-to-day use; this risk may arise from damage, deterioration, improper installation, or changes in accepted residential construction practices. Wall coverings serve as a protective or insulating layer fixed to the outside of a building and can include materials such as aluminum, brick, EIFS, stone, stucco, vinyl, and wood. Lastly, a wiring method includes identifying electrical conductors or wires by their general type, such as non-metallic sheathed cable, armored cable, and knob and tube, among others, reflecting the safety controls definitions relevant in home inspections.
