A. An accessory dwelling unit (ADU) shall not be larger than twenty percent (20%) of the lot area and the ADU shall not have more than one (1) bedroom. Where practical, the twenty percent (20%) size standard may be altered to accommodate logical expansions or internal conversions. Examples of this include, but are not limited to, the addition of a second floor to a detached garage or the separation of a basement as an accessory unit.
B. ADUs shall meet all of the dimensional requirements of the land use district and requirements of the Ada County Building Code as set forth in title 7, chapter 2 of this Code.
C. The design of the ADU shall be compatible with the existing neighborhood by taking into account height, bulk, and site location, and incorporating materials, colors and a design motif that is compatible with and complements the architectural theme and style of the principal dwelling unit. The principal and the ADU shall be designed to portray the character of a single family dwelling. Only one (1) entrance to the structure may be located on the front building elevation of the house unless multiple entrances are already in existence.
D. Off-street parking shall be provided as per section 8-4G-6 of this title, in addition to the required off-street parking for the principal permitted dwelling. The driveway apron (driveway space within the front yard setback) may be utilized for this requirement.
E. Input from adjacent property owners should be considered in the design and siting of an ADU in order to maintain privacy between adjacent housing units. (Ord. 703, 2-10-2010; amd. Ord. 864, 2-21-2017)
