Which statement best describes a Building Component Type?

• A. Items in the interior or exterior of housing onto which paint, stain, varnish, or shellack has been applied and that have a common substrate
• B. The physical foundation of the building
• C. The color of paint chosen for a room
• D. The type of brush used

Answer: (A)

Building Component Type describes surfaces that share a common substrate and have the same kind of finish, treated as a single unit for assessment. It refers to items inside or outside the home onto which a finish like paint, stain, varnish, or shellac has been applied and that all sit on the same material under the finish. This grouping helps inspectors plan sampling and interpret results, since surfaces under the same component are likely to have similar lead-based paint characteristics. For example, all wood window trim and interior doors finished with the same paint form one component because they share the wood substrate and the same type of finish. In contrast, a building foundation or a completely different material (like metal siding or drywall) would be a different component due to a different substrate. The color or the brush used isn’t what defines a component; it’s the surface material under the finish and the finished surface itself.
