Constructing an ancillary dwelling unit offers homeowners the potential for additional living space, rental income, or accommodation for extended family. For example, a detached structure with its own kitchen and bathroom could serve as a long-term rental, generating supplemental income for the property owner. Alternatively, a smaller attached unit might provide comfortable living quarters for aging parents or visiting relatives.
The ability to create additional dwelling units offers significant advantages, contributing to both individual property value and community housing density. Historically, such structures have provided flexible housing solutions, evolving from carriage houses and converted garages to modern, purpose-built additions. These units can increase affordability and address housing shortages in densely populated areas. They also offer homeowners greater flexibility in utilizing their property.
