Note 1: Single-Family Attached and Townhouse Development. Regulators are shown on a per unit basis. Side yard setbacks are indicated for detached building walls.
Note 2: Multi-Family Development. The minimum side yard setback increases by 1 feet for each 1 foot in height above 35 feet, up to a maximum height of 50 feet.
Note 3: Zero Lot Line and Single-Family Attached Development. Within a common development, one interior side yard may be equal to zero for single-family detached residential use if:
1 The normal side yard setback requirement must be maintained adjacent to any lot with an existing structure not within the common development; or not otherwise designated for zero lot line use.
2. An easement for maintenance of the zero lot line façade is prepared by the developer and filed with the Crawford County Register of Deeds, the City Clerk, and the Building Official at the time of application for a building permit.
Note 4: Flexible Yard Setbacks in Planned Districts. The Planning Commission and City Council may vary required minimum setbacks in planned districts. However, the setback from the front facade of a garage to any public or private street right-of-way including the boundary of sidewalks must be at least 20 feet.
