City Council Staff Report <br /> 7/14/2025—Amend Zoning Code—Detached ADUs <br /> Page 2 <br /> Work Session: <br /> The City of Mounds View convened a work session on June 2, 2025, that included participation <br /> from City staff, the Planning Commission, and the City Council. There was extensive dialogue <br /> regarding the potential allowance of detached accessory dwelling units (ADUs), including a <br /> review of practices in peer and neighboring municipalities, as well as the broader implications of <br /> permitting or prohibiting such units. Following this discussion, there was consensus in favor of <br /> allowing detached ADUs as a conditional use, subject to the review and implementation of <br /> specific standards and conditions. <br /> City Code: <br /> § 160.088 CONDITIONAL USES lists the conditional uses permitted in the Single-Family <br /> Residential (R-1) district. The land use classifications in Mounds View follows hierarchical <br /> zoning, where all the uses listed in the R-1 district are also allowed uses in the R-2, R-3, and R- <br /> 4 districts. <br /> Figure 3:Example of an ADU(detached). <br /> If allowing detached ADUs, staff would propose a new subsection with standards specific to <br /> detached ADUs. The proposed draft would make these a conditional use in the R-1, R-2, R-3, <br /> and R-4 districts. <br /> The draft ordinance is based on the current requirements for accessory buildings (160.087(A)) <br /> and ADU (internal) (160.087(J)) in the city code, the draft ordinance prepared by city staff in <br /> 2023, as well as research by current staff on neighboring communities. Staff have included <br /> excerpts from the draft ordinance in italics below for the commissioners to further consider, with <br /> staff comments following. <br /> • One detached accessory dwelling unit may be located on a lot occupied by a single- <br /> family home. The lot must comply with minimum dimensional standards. <br /> o Only one accessory dwelling unit, whether as an addition, internal, or detached, <br /> shall be permitted on a lot. <br /> o Does the commission want to allow multiple ADUs on the same lot? <br /> • An accessory dwelling unit (detached) shall have a minimum gross floor area of 300 <br /> square feet and a maximum gross floor area of 50% of the primary residence. <br /> o The footprint of an accessory dwelling unit (detached) shall count towards the <br /> maximum area allowed for accessory buildings as specified in §160.087(A)(2). <br /> The Mounds View Vision <br /> A Thriving Desirable Communit <br />
