Accessory dwelling units (also known as accessory apartments, guest apartments, in-law apartments, family apartments or secondary units) provide supplementary housing that are integrated into existing single family neighborhoods to provide a lower priced housing alternative with no negative impact on the character of the neighborhood. Because the units are small, they are more affordable than full-size rentals.


Frequently Asked Questions

What are the benefits of Accessory Dwelling Units(ADU)?

Adding an ADU has many benefits to homeowners including giving them the ability to care for a family member and providing extra income by renting the ADU to both family members or non-family members. It also allows homeowners in need of at-home services, to offer low or rent free housing to those performing those services. The ALU provides a moderately priced rental option for low-income residents as well.
