9.A. - Page 4 of 43 <br />and second -story above a detached garage, and noting that second -story ADUs regulations were recently <br />approved in 2019. Other nearby municipalities, including San Carlos and Belmont, have allowed ADUs <br />above legally established detached garages with a maximum height of 20 ft., as long as the ADU footprint <br />does not extend beyond the garage footprint. <br />Based on the diagrams by the design consultant (Attachment C), a maximum height of 16 ft. would allow <br />for a one-story building with loft space suitable for storage but not a second floor living area. An 18 ft. <br />ADU would allow for a two-story with a flat roof and short ceiling heights, but adequate for living space <br />and sleeping quarters. A 22 ft. ADU would allow for multiple designs for both a partial two-story ADU and <br />a two-story ADU with full plate heights on the entire upper floor and a pitched roof. ADUs with lower <br />heights could cause some architectural constraints to roof slope that may not allow an ADU to match the <br />architectural style of the main home. <br />In 2019, 2020, and 2021 a total of 186 ADU applications were submitted and of those 26 (13%) were for <br />detached ADUs above 16 ft. in height.
