CC Work Session 2.4. Meeting Date: 12/14/2021 Information Title: Discuss Ordinance #21-18 Amending Section 117-349 of City Code to Allow Accessory Dwelling Units (ADU's) Purpose/Background: Summary At least once a month, Planning Staff receive calls from residents requesting information about mother-in-law suites, or some other form of an Accessory Dwelling Unit. Planning Staff have a proposed ordinance to allow attached, and detached, Accessory Dwelling Units (commonly known as ADUs) in the City of Ramsey for single-family residential properties only, at the request of the Planning Commission during their regular meeting on July 22, 2021. Planning Commission Meetings (July - October) The Planning Commission recommended City Staff pursue an accessory dwelling unit ordinance, after discussion of Council Business during their July regular meeting. Since then, City Staff have worked with the Planning Commission over the last few months to create an ordinance that would be recommended for introduction by the Planning Commission. Minutes from the various meetings are attached to this case. Planning Staff researched surrounding city requirements for ADU's, discussed multiple aspects of the case, and prepared a draft ordinance - which was reviewed and recommended for introduction by the Planning Commission during their regular meeting on October 28, 2021. The proposed ordinance reflects some of the most recent additions requested by the Planning Commission: • Modeled after Dayton's ADU ordinance • No minimum lot size for attached, but minimum lot width • Minimum lot size of 2.5 acres for detached ADU's • No options for Interim Use Permits Types ofADU's • Attached— e.g. mother in law suite above garage, two separate entrances to the home, essentially a home addition but it's a suite. Requested occasionally from callers, but not as often as detached. • Detached— converted garage, tiny home on a foundation etc. most often requested from callers. • Internal— suite within the existing home, our code already allows this so long as the entire home (suite + existing home) is accessible via the front door. These are typically converted basements. Our code doesn't limit # of kitchens, bathrooms, etc. so this has not been a request from residents. Proposed Regulations General requirements from Cities that have ADU's that were incorporated into the ordinance include: • One (1) ADU per residential lot; • Allowed on existing single-family residential properties only; • Principal dwelling and/or ADU must be owner occupied; • Compliant with all other city, local, regional, state, and federal regulations; • Building code standards and permits (utilities, stairways, equipment, etc).; • Match primary residence (siding, material, roof pitch, trim, windows, projecting eave, etc.); • Maximum size of 800 sf— Attached and Detached • Conversion of portion of detached garage is allowed (800 sf max); • Cannot create a new tax parcel or be sold separately from the primary residence; • Cannot be utilized for Home Occupations;
