August 6, 2025 Centerville Planning & Zoning Commission Page 7 of 8 Reference: Zoning Code Issues & Definitions garage or accessory building shall be permitted closer to the front lot line than the front building line or edge of the principal building, provided that the minimum front setback for principal buildings is met Ͻ϶there is screening between the structure and the right-of-way, and that all other required setbacks are met. (5) Detached accessory buildings must have a minimum of a 5-foot interior side setback and a 10- foot rear setback. Where a rear or side yard abuts a street For a corner or through lot, a detached accessory building shall be to the side or rear of the principal building, and shall adhere to the required street side setback as established in Appendix A, Table 1 set back a minimum of 20 feet from any lot line abutting a road the street property line. No structure may be placed in an easement, except bridges by written permit approved by the City Council. Accessory Structure Sizes After reviewing a previous variance, the Council asked the commissioners to look at accessory structure requirements for residential zones, in particular the size limits and allowances currently within code. Below are the current standards found in § 156.107(A): (1) No more than two detached accessory buildings are permitted on any single-family, detached dwelling parcel located in any district except R-1. Combined aggregate square footage for detached accessory structures shall not exceed 200 square feet or 2% of the lot area, whichever is greater, except if the lot has no attached garage, the largest detached structure may not exceed the square footage of the main floor dwelling. (2) In no event may any accessory building exceed the square footage of the main level of the principal structure, except in the R-1 District. (9) Detached parking garages for residential uses may be allowed to exceed the area limitations above, but only with a finding that underground or attached parking is impractical or infeasible. Staff reviewed the standards in nearby communities, to identify what neighboring cities permit. Some cities base their requirements on zoning district, while other cities have a Òsliding scaleÓ, where the amount and number of detached accessory structures is based on the size of the lot. Staff finds that this is a common approach in the Twin Cities region. For example, the city of Hugo does the following: Table 1: Detached Accessory Structure standards - Hugo Lot Size Maximum combined size # of Detached Accessory allowance of all Detached Structures Accessory Structures Under 1.5 acre 260 square feet One 1.5 acres to 2.99 acres 1,500 square feet 3 acres to 4.99 acres 2,000 square feet Two 5 acres to 9.99 acres 3,500 square feet 10 acres or more 5,000 square feet Three Given the development pattern of Centerville, a Òsliding scaleÓ like above could be used with different lot size breakdowns (such as using the minimum lot sizes in each zone) and size limitations/allowances. The current limit of 2% of the lot area acts as a sort of sliding scale already; does the city find that number low 9
