TO:Chair Peterson and Planning Commission Members FROM:Michael P. Gaffron, Asst. Planning & Zoning Administrator DATE:January 4,1996 SUBJECT: Proposed Zoning Code Amendment - Oversized Accessory Structure Table List of Exhibits A - Section 10.03, Subd. 9 B - Amendment Option I C - Amendment Option 2 D - List of Typical Oversize Accessory Structures Summary It was recently pointed out that the oversized accessoiy' structure ordinance adopted in 1989 places a 3,000 s.f. limit on the footprint area of individual accessory buildings, and a 6,000 s.f. limit on the aggregate square footage of all accessory buildings on a property, regardless of acreage in excess of 9 acres. It was suggested to staff that this be expanded to allow additional square footages for properties larger than the current 9-acre threshold. A number of options are presented for Planning Commission's consideration. Background A recent building permit application for an accessory structure on a 20-plus acre residential parcel required a variance application due to the 6,000 s.f. accessory structures limit per the table in Section 10.03, Subd. 9(C-2). That table, and the requirements for meeting principal structure setbacks, limiting height, and requiring execution of a \NTitten covenant, were adopted in 1989 to allow some flexibility for accessory structures on large properties without the need for a variance. The current table sets 1,000/2,000 s.f. limits (each accessory structure/all accessory structures) for lot areas less than 2 acres. The table then adds 200/400 s.f. for the third acre; an additional 200/400 s.f. per each additional half acre until the 5 acre threshold; then 200/400 s.f. per additional acre up to the 9 acre threshold, above which no additional square footage is allowed. In each case, the allowance for total accessory structures is double that for individual structures. The table yields a decreasing percentage of lot area potentially covered by accessory structures as lot area increases. For example, a 2 acre lot with 2,400 s.f of accessory structures is 2.20% covered. A 5 acre lot with its allowable 4,000 s.f of accessory structures is 1.93% covered. A 9.01 acre lot with its full complement of 6,000 s.f of accessory structures is 1.45% covered by accessory buildings. r: liL- : — I'-t,
