while maintaining a degree of privacy. 2.2b Why would Roseville discourage accessory dwellings? Accessory units could create land use problems because they: 1. Turn into rental units of umelated individuals, hard to limit occupant number. 2. Many times have non-professional homeowner construction and maintenance; 3. Design details may not be sensitive to other structures in the neighborhood; 4. Parking and access can be a problem if not installed with construction; 5. Create more impervious surfaces (more roof and parking surfaces); 6. Could create a safety problem (access) in areas where of the existing house is not accessible or there is no alley or comer access. 2.3 What conditions will allow for the establishment of an ADD? An accessory dwelling unit may be created through the following: 1. Internal conversion within an existing dwelling: 2. Additions to existing house or garage (and be located at least 30ft back from the front property line); 3. Conversion of an existing garage if it is set back at least 40ft from the front property line; 4. Inclusion in development plans for, or part of, the construction of a new single family detached dwelling unit; or 5. A separate detached dwelling unit that must be located at least 6 feet from any structural element of the primary unit. 2.4 Can an ADD be established on a lot there are two single-family units or townhomes on the lot? An accessory dwelling unit may not be established on a lot of record with two or more single- family residences. 2.5 Does an accessory dwelling need a building permit? Yes. Before receiving a building permit to establish an accessory dwelling, the applicant must record a deed restriction covenant with the Ramsey County Recorder certifying that the owner is occupying one of the dwellings on the lot. An ADD comply with applicable building, fire, and health and safety codes. An ADD cannot be occupied until a Certificate of Occupancy is issued by the Community Development Department. 2.6 Does an ADD have to connect to water and sewer? Yes. An accessory dwelling unit must connect to public sewer and water. 2.7 What is the maximum area allowed for an accessory dwelling within the primary dwelling? The total gross floor area of an accessory dwelling must not exceed forty percent of the area of the primary dwelling's living area, excluding uninhabitable floor area, the garage or other outbuildings. If the accessory dwelling unit is a separate building on the site, in addition to the forty percent size requirement, the ADD along with all other impervious surfaces cannot exceed thirty percent of the site, except with a variance. 2
