Oregon Construction Contractors (CCB) Practice Test

A residential building is characterized by being a structure designated for people to live in, specifically focusing on units constructed for residential occupancy. The definition includes buildings with no more than four units, which can encompass single-family homes, duplexes, triplexes, and fourplexes. This aligns with common zoning regulations and building codes that distinguish between residential and multi-family or commercial properties.

In contrast, the other choices pertain to different types of structures. A structure with more than four units typically represents multi-family or commercial buildings, which fall outside the residential classification. A single-family dwelling only describes one specific type of residential building but does not encompass the broader category that includes two or three-family homes. Lastly, a commercial property is designed for business purposes, thus clearly separating it from residential classifications. This clarity in defining residential buildings ensures compliance with regulations and building codes relevant to construction contractors.
