Home My WebLink About5. Zoning Ordinance Text Amendment for Accessory Structures t � City of Rosemount Executive Summary for Action ' City Council Meeting Date: September 6, 1994 � Agenda Item: Zoning Ordinance Text Agenda Section: Amendment: Accessory PUBLIC HEA.RING Structures Prepared By: Richard Pearson Agenda No: Assistant Planner '�E� � � Attachments : P.C. Memo; Public Notice; Approved By: Draft Ordinance. The attached zoning ordinance text amendment will create some ability for residents in the Rural Residential and Ag�iculture Districts to build accessory structures larger than the current maximum of 1, 200 square feet. The amendment also attempts to make the accessory structure language "user friendly." The Planning Commission discussed the amendment on July 26th and again on August 9, 1994 when they passed a motion to recommend approval. It should be noted that discussions centered on existing standards that would be unaffected by the amendment. Every year Planning staff responds to requests for accessory structures in the Rural Residential and Agriculture Districts . Pole barns are prohibited on non-agricultural uses of less than 20 acres, west of Akron Avenue. The original intent of the ordinance was to eliminate or reduce rural home occupations that tend to accumulate junk cars and debris as a by-product. Other requests have to do with size. A structure as large as 3, 000 square feet can be attached to a house and called an attached garage. Detached accessory buildings and garages are limited to 1, 200 square feet total . The text amendment xecommendation is intended to provide some flexibility to the size limitation while still providing the needed prohibitions . This is in light of 'the fact that several people have recently constructed massive "attached" garages . Recommended Action: A MQTION to adopt Ordinance No. B-46 AN ORDINANCE AMENDING ORDINANCE B - CITY OF RO5EMOUNT ZONING ORDINANCE for the regulation of detached accessory structures in the Rural Residential and Agriculture Districts west of Akron Avenue .

ATTAC�Iv'rs: Application; Survey; Fxcerpt of Current Ordinance. 6b. Zoning Ordinance Text Amendment: Accessory Structures - Rura1 Residential District (Badger Basen: 12250 Cobblestone Lane) PttOPos�,: Mr. Badger Basen lives in the Rura1 Residential district on a 4 acre lot. He owns a 40 foot long motor home RV and is required to store it within a building according to the restrictive covenants of his neighborhood development. To accomplish this, he wants to construct a 1500 sq. ft. building which is 300 sq. ft. larger than the maximum area allowed'for an accessory structure including detached garages. A variance was discussed originally to process the request. However, there was difficulty with establishing the "hardship" needed according to the findings required to grant a variance. There might also be circumstances in which other property owners in the rural residential district may want a large accessory building - especially in Mr. Basen's neighborhood. DISCUSSION: Accessory structures are regulated in a variety of ways by other Cities. I have assembled information from neighboring cities for comparison purposes. APPLE VALLEY LOW DENSITY RESIDENTIAL DISTRICTS: Maximum size is 750 sq. fi. which is equivalent to a detached three-car garage. ' BURNSVII..LE RESIDENTIAL DISTRICTS: Accessory structures exceeding 1000 sq. ft. require a conditional use permit. INVER GROVE HEIGHTS: Single family uses limit accessory structures to 1000 ft. sq.

July 26, 1994 P.C. Meeting Reviews ~ ) Accessory Building Z.O. Text Amendment � � �. � Page Two Cootv Rapms had an interesting approach which provides some flexibility: 768 sq. ft. or 75% of the,flvor area of the dwelling unit whichever is larger to a maximum .. _ of 1200 sq.ft. Ros�otm�r: 1 Z00 sq. ft. for Rural Residenrial or non-agriculture uses on less than 20 acres west of � Akron Avenue. Some of the above cities may not have the same type of rural residential uses if their residential land is generally within the Metropolitan Urban Service Area (MUSA). Lakeville makes such a distinction between R-1 and R-2 and 3 with the latter two being in the MUSA with sewer and water. CONCLUSION The important aspect of raising the allowable size requirements for accessory structures is ensuring that the residential use remains the principal use in terms of function as well as appearance. To that end, no accessory structure in a residential setting should be similar in size or larger than the principal structure which is the dwelling unit. The solution is to lirnit the size of accessory structures to be proportionately smaller than the principal structure. Anotl�er concern is the possible proliferation of undesirable home occupations in the rural residential district. There are restricrions on home occupations that are intended to eliminate the nuisances of some home occupations. Additional current standards require compatibility of accessory structures with dwelling units aesthetically through the use of like materials and the requirement for minimum roof pitch and shingles for buildings exceeding i50 sq. ft. RECOlvIl1TENDATION Planning Staff recommends a text amendment allowing an increase in the maxunum area standard for accessory structures in the Rural Residential districts based upon the following criteria: 1. Accessory buildings over 150 sq. ft. in size shall ha�e a minimum 3:12 roof pitch; 2. Roofs shall be shingled with asphalt, wood or tile to match the home; 3. An adequate number of windows shall be provided to break up the solid plane or exterior walls to simulate the character of the home; 4. Siding which is identical or closely matches the home shall be incorporated in the design of the accessory building; 5. The maximum aga egate area for accessory structures shall not exceed fifty percent of _ the area of the principal structure including attached garage; 6. The minimum setback standards for accessory structures exceeding 150 sq. ft. shall be the same as principal structures; and 7. Maximum lot coverage shall not esceed 10%. k { ��i��'�'��;� � C I TY O F RO S E M O U N T Z875 C145th SAt eet West P.O.Box 510 Ever thin s Comin U Rosemount!!
