With a Residential Small Commercial license (R100), how many multi-family units can a contractor build?

The correct choice indicates that with a Residential Small Commercial license (R100), a contractor is permitted to build a multi-family structure consisting of four units, commonly referred to as a four-plex. This type of license is specifically designed to allow contractors to manage residential projects that are on a smaller scale and that include multi-family dwellings.

The limit of four units is significant in distinguishing the capabilities of the R100 license from other categories that might allow for larger residential projects or different types of commercial construction. This regulation helps ensure that contractors focus on projects that align with their licensing qualifications, which can vary by state or governing authority. Understanding these limits is crucial for compliance with regulatory requirements and helps contractors operate within their legal bounds while also catering to specific market needs for smaller multi-family housing solutions.
