practical level, since the PMC applies the greater of the three maximum sizes listed, a maximum of 1,200 square feet will be allowed in many instances, consistent with the maximum ADU size currently allowed in the PMC. Nonetheless, this approach mirrors the (difficult to interpret and apply) state law such that the proposed amendments to the PMC are consistent with these different variables and limitations, while at the same time upholding the standards currently in the PMC. Despite this, it is important to reiterate that, the PMC would require that an attached ADU exceeding any of the Minimum ADU Standards comply with applicable development regulations for the zoning district or PUD in which it is located; thus application of floor- area-ratio maximums, minimum open space requirements etc. may further restrict the above-listed maximums, although in no case can the ADU be restricted to less than 800 square feet. c. Detached Single-Family ADUs [see Exhibit A, PMC 18.106.045] The changes proposed to the PMC related to detached ADUs principally pertain to square footage maximums, as well as requiring second-story ADUs to meet objective standards. (i) Height The maximum height for a detached ADU is 16 feet, consistent with the Minimum ADU Standards (one foot greater than the existing height maximum of 15 feet); detached ADUs are limited to one-story. In the current and revised PMC, an exception is provided for an ADU proposed above a detached garage, in which case the maximum height is 25 feet in the R-1 , RM, and MU districts and 30 feet in the A district (the 25-foot height limit currently exists for the R-1 and RM districts and is proposed to be carried forward to the MU District). ADUs proposed above a detached garage in the C-C District would be limited to 40 feet, which is the existing height limit for accessory structures. The provision to allow ADUs above detached garages was added as part of the modified ADU regulations adopted by the City in 2013 and no change to the overall height limits (or to the setback requirements) is proposed. The detached ADU above a garage would, however, need to meet objective standards (see the section titled, Proposed Objective Design Standards, intended to address such issues as neighbor privacy and compatibility with existing buildings). (ii) Setbacks Detached ADUs are required to be located a minimum of 4 feet from side and rear property lines if they are proposed as one-story structures up to 16 feet in height. If proposed above a garage, the ADU must be at least 5 feet from side and rear property lines, even in the C-C District where no setbacks are required for accessory structures. For corner lots, a 10-foot street side setback would be required (consistent with the current PMC) in situations where the ADU does not meet any one of the Minimum ADU Standards. An ADU that meets all of the Minimum ADU Standards could have a 4-foot setback, even on the street side of a corner lot. The new state law indicates that no setbacks may be required when either of the following types of structures are converted to an ADU: (1) a legal, existing accessory structure; or (2) a non-conforming structure when the ADU is constructed in the same location and with the same dimensions as the non-conforming existing structure. This is more permissive than the existing requirement since the PMC currently indicates no setbacks are required for existing garages P20-0412, Accessory Dwelling Units Planning Commission 5 of 13 y zoning districts include the RM and MU districts. The Central-Commercial (C-C) District also allows multifamily dwellings and thus in accordance with the new state law, must now also allow ADUs; JADUs would be allowed in existing single-family dwellings.
