ADUs, commonly called Guest Houses, are defined in the San Juan County Code as:
Accessory dwelling unit (ADU)" means a living area that is accessory to the principal residence, located on the same lot, and that provides for sleeping quarters, kitchen, and sanitation facilities. An ADU may be internal, attached or detached.
Within land use districts located inside of the boundaries of activity centers and urban growth areas, there is no restriction on the number of permits for detached accessory dwelling units. Outside of the boundaries of activity centers and urban growth areas, there are five (5) permits for the construction of new ADUs and one (1) permits for the conversion of existing accessory structures (legally in existence for five years) available for 2021.
San Juan County Department of Community Development (DCD) is accepting applications for detached ADU permits proposed outside of urban growth areas and activity centers until 4:30 pm February 8, 2021.
