(Am. Ord. #02-18)

Notes:

1.

Subject to the maximum lot coverage, building height, building setback or other applicable allowances and limitations, there is no maximum size (area) for an attached garage.

2.

If an existing dwelling unit includes an attached garage, then the maximum floor area allowed for all detached accessory buildings (cumulative total per lot or parcel) up to the percentage noted of the net lot or parcel area (in square feet) or 192 square feet, whichever is greater. (Am. Ord. #02-18)

3.

The 1 percent maximum floor area allowance applies to each dwelling unit on a lot or parcel in the Rd-2 2-family zoning district.

4.

Many residential lots in the older established areas of the Village do not have (or may not be capable of having) an attached garage due to lot width, building setback, septic system location, or other limitations associated with substandard lots. In these cases, the maximum floor area allowed for all detached accessory buildings (cumulative total per lot or parcel) is 1% of the net lot or parcel area (in square feet) or 864 square feet, whichever is greater.

5.

The calculation of "maximum floor area" for detached accessory building shall include:

a.

All floor area (including second or higher floors) where the ceiling height above the floor is 6 feet or higher; and

b.

If in the Rs-1 or Rs-2 District, any additional area under cover by an overhang that is greater than 2 feet from the exterior wall on three sides of a building, plus the area under cover by an overhang that is greater than 6 feet on the remaining side(s).

c.

The number, type, architecture and materials for all accessory buildings and structures in business and industrial zoning districts are subject to Site Plan review and approval by the Plan Commission.

(2)

HEIGHT LIMITATION. (Am. Ord. #8-96; Am. Ord. #42-99; Am. Ord. #15-07) Except in the Rs-1 and Rs-2 Zoning Districts, no detached accessory structure located in any single-family or 2-family residential district shall exceed 15 feet in height, except the total height of the structure may be increased to a maximum of 25 feet or the height of the principal dwelling unit on the property, whichever is less. In the Rs-1 and Rs-2 Zoning Districts, the maximum accessory building height is 25 feet.

(2a)

ARCHITECTURAL APPEARANCE AND MATERIALS. (Cr. Ord. #02-18) In single-family and 2-family zoning districts (Rs-1 through Rs-7 and Rd-2), accessory buildings which exceed 160 square feet in area shall be of a similar architectural appearance and exterior material as the dwelling on the property. For accessory buildings greater than 160 square feet in area, the Plan Commission may, in circumstances which it deems appropriate, grant a variance to this requirement and approve different architecture and/or exterior materials with a Zoning Permit. See also Section 17.49 (ARCHITECTURAL CONTROL).
