Accessory Dwelling Units

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.

See Section 404.24 of the Land Development Code (ULDC) for more detailed information about Accessory Dwelling Units.

In what zoning districts are ADU's allowed?

One additional living unit is allowed accessory to the principal structure without counting toward gross residential density in the following residential zoning districts: RE, RE-1, R-1aa, R-1a, R-1b and R-1c in Estate Residential, Low Density, or Medium Density land use designations and in the A zoning district in Rural/Agriculture land use designation.

Accessory units have no minimum size and may be a maximum of 50% of the gross square footage of the principal residence or 1700 SF, whichever is greater.
