REQUEST FOR COUNCIL ACTION <br />Date: March 23, 2020 <br />Item No.: 7.b <br />Department Approval City Manager Approval <br />Item Description: Consider adoption of an ordinance amending Title 10, Zoning, mainly pertaining <br />to height limitations for detached Accessory Dwelling (PROJ0017) <br />1 <br />B ACKGROUND <br />Application Information <br />Applicant: Jeffery Lewis <br />Location: N/A <br />Property Owner: N/A <br />Open House Meeting: N/A <br />Application Submittal: Submitted and considered complete February <br />7, 2020 <br />City Action Deadline: April 7, 2020, per Minn. Stat. 15.99 <br />1 Level of Discretion in Decision Making <br />2 Actions taken on a zoning text amendmentrequest are legislative in nature; the City has broad discretion <br />3 in making land use decisions based on advancing the health, safety, and general community welfare. <br />4 Accessory Dwelling Unit History <br />5 Only a small number of Accessory Dwelling Units (ADUs) have been approved since they were first <br />6 allowed by the major zoning code update in 2010, and most of these ADUs have been attached—that is, <br />7 added to (or incorporated into) the principal structure on aresidential property. Since 2010, the zoning <br />8 code has also allowed detached ADUs, whether these are in their own discrete building or beside or <br />9 above a detached garage. More recently, though, inquiries from homeowners about ADUs above <br />10 detached garages have been increasing considerably in frequency. In responding to these inquiries, <br />11 Planning Division staff has discovered that the existing regulations about the height of detached ADUs <br />12 are tied directly to the height of detached garages, which interferes with the intent of the zoning code to <br />13 allow an ADU to be built above a detached garage. <br />14 Since Roseville first adopted a zoning code in 1959, the overall height of accessory buildings was <br />15 limited to 15 feet and, sometime later, a maximum wall height of 9 feet was added. There are three <br />16 primary reasons to restrict the height and area of accessory structures like this: <br />17 1) to allow the residence to remain the principal use on a residential lot, both visibly and <br />18 practically; <br />19 2) to make clear that accessory buildings of an agricultural, industrial, or commercial scale are not <br />20 allowed in Roseville’s residential districts; and <br />7b rca <br />Page 1 of 3 <br /> <br />
