Advantages of the New Implementation:
Increased Housing Availability: ADUs provide additional housing options within existing neighborhoods, helping to address the city's housing shortage.
Affordable Housing: By allowing homeowners to create rental units, the initiative supports the availability of more affordable housing options.
Homeowner Benefits: Homeowners can generate additional rental income and provide space for multigenerational families without significantly altering the neighborhood's character.
