It’s important to note that cities permit ADU’s differently. For example, Andover allows ADU’s only on lots zoned for 2.5+ acres. Plymouth allows ADU’s only if the home was originally constructed with an ADU. St. Paul allows ADU’s only within carriage houses, but is considering allowing them along the University Ave. LRT corridor. Roseville allows ADU’s as a permitted use, but requires notification of all neighbors prior to administrative approval. New Brighton allows ADU’s only on lots twice the minimum lot size, and only for use by the homeowners’ employees (i.e. nanny, caretaker, etc.). Since Minneapolis amended their ordinance in 2015 to allow ADU’s, the city has issued 50 permits. By contrast, nine suburbs queried by Staff stated that they typically issue 0- 1 ADU permits per year (mostly, zero). When Richfield amended their ordinance to allow ADU’s, a number of property owners with illegal ADU’s applied for permits to become legal units, but the city has not received any applications for “new” ADU’s. The Mounds View Planning Commission has discussed ADU’s extensively. Highlights of these discussions include: Ownership: Either the home or the ADU is to be owner occupied, and homesteaded. Homestead may include “Relative Homestead”, in which a relative may occupy the home instead of the homeowner. To counter this, some cities have required that the owner record a covenant, requiring homeowner occupation. Staff believe that a covenant is not necessary, and that requiring a condition of CUP approval, that the property be owner occupied is sufficient. Rental License: If the ADU does not have access into the home, the owner will need to obtain a rental license, and would be inspected by the City every other year. ADU Size: If the ADU is internal to the existing home (i.e. conversion of a basement or second floor), then the minimum size is 300 sq ft, and maximum size can be no larger than the floor above or below the ADU. If the ADU is to be a home addition, or in an accessory building, then the minimum size is 300 sq ft, and maximum size 800 sq ft. These size limitations are consistent with many other cities. It is possible that a small house less than 800 sq ft in area could add on an 800 sq ft ADU. The Council may want to consider requiring that the ADU cannot exceed the size of the principal structure (home). Accessory buildings are limited to a height of 18’ (from ground to roof peak). It is unlikely that an existing detached garage attic could be converted into an ADU (trusses are different if for storage vs living area). A new detached garage could have an ADU above it, but would still need to be 18’ or less in height. Setbacks: ADU’s are to comply with the same setbacks as homes (10’ side and rear yard setback).
