Accessory Dwelling Units

Accessory dwelling units (ADUs), also referred to as in-law apartments and as second units, are independent living spaces secondary to the main living area. They can be cottages, conversions, carve-outs, or a new special category, junior accessory dwelling units. This type of infill housing provides a wide range of benefits:

Homeowners benefit because rental income makes owning a home more affordable and can provide access to homeownership, because the value of the home increases, and because family members or caregivers can be housed

Renters benefit because they have more options for affordable housing and may have shorter commutes

Communities benefit from the diversity that comes with multi-generational housing,  from additional housing consistent with neighborhood character, from additional employees and customers for local businesses, and from a reduction in commuter traffic

Government benefits because second units, as well as junior second units with private bathrooms, count toward affordable housing requirements (RHNA), and because property taxes increase for homes with legal second units

The Planet benefits from a reduction in commute-related carbon emissions, and from more efficient use of existing resources
