    Concept Review Complete: Corrections Required

    The ADU as proposed is not meeting our code requirements for allowable square footage.The maximum square footage allowed for an ADU is 900 sq. ft. For detached accessory structures covered parking spaces, covered exterior stairs, and covered decks are included in the total.So, once we add the area under the balcony and the covered porch, the square footage as proposed is 1,231 sq. ft.Additionally, the intention of an ADU is to be secondary and incidental to the primary home. The massing of this two-story proposal overshadows the single-story existing home, which is the primary use on this property.Finally, an ADU does not require additional parking, and the proposed driveway does not meet our code requirements, as we cannot support a second access.
