Accessory buildings, except as otherwise permitted in this title, shall be subject to the following regulations:
A. No accessory building or structure shall be permitted in any required front yard; provided, however, that flagpoles may be located not less than ten feet (10') from the front and side lot lines, and basketball hoops and backboards not exceeding thirteen feet (13') in height may be located so that no portion of such structure (including the backboard) extends beyond the front lot line or within five feet (5') of the side lot line.
B. Where an accessory building or structure is structurally attached to a principal building, the accessory structure shall be subject to, and must comply with, all regulations of this title applicable to the principal building. An accessory building connected to a principal building via an open walled covered walkway shall be considered to be structurally attached to the principal building. For purposes of this subsection, a walkway shall be deemed to be "covered" if any type of building or structural support materials of any kind connect the upper half of the vertical elements of the walkway.
C. Except as provided in subsection D of this section, an accessory building or structure shall not be located less than five feet (5') from any interior lot line or not less than five feet (5') from the rear lot line. On a corner lot, along a street line that is determined to be the side of the lot, accessory buildings and structures shall not be located less than twenty percent (20%) of the width of the lot to such street line, or less than the applicable required front yard setback or required corner lot side yard setback for a principal structure or building on the adjoining lot along the same street line, whichever distance is greater.
D. An accessory building or structure located, in whole or in part, along that portion of the rear or side lot line that forms part of the front half of the side lot line of an adjacent lot shall not be located less than ten feet (10') from the rear or side lot line of the lot on which any such accessory building or structure is located; provided, however, that this restriction shall not apply to any accessory building or structure that is erected eighty feet (80') or more from any street bounding the block; and provided further, that in the C (R-5), B (R-4), and A (R-3) Residence Districts, an accessory building or structure, with neither a width nor depth exceeding ten feet (10'), nor a height exceeding ten feet (10'), may, if located entirely in the required rear yard, extend to within two and one-half feet (2.5') of the rear lot line and to within two and one- half feet (2.5') of an interior side lot line; provided, that the portions of such lot lines along which any such accessory building or structure, or any part thereof, is located, does not form the front half of an adjacent lot, and does not form the half of the lot closest to the side street for a corner lot or an adjacent corner lot. (See section 10-13-1, illustration 6A of this title.)
E. An accessory building or structure that is considered to be a garage, shed, greenhouse, or any other type of miscellaneous enclosed building shall not be located less than five feet (5') from any principal building, or from any structure attached to a principal building, or less than three feet (3') from any deck attached to a principal building or structure, provided such deck is of a type specified in subsection 10-5-6B3 of this chapter.
F. An accessory building shall not be erected or used prior to the construction and use of the principal building. An accessory building or use may be maintained for a period no greater than one year after the date that the principal building is demolished or the principal use in the principal building is ceased, unless a building permit is issued and construction is actually begun within that one year period and is thereafter diligently pursued to completion, or unless a certificate of occupancy is issued and a use commenced within that period.
Where an accessory structure or use is to be maintained in the absence of a principal structure or use under this subsection, the Building Commissioner may require the property owner to execute a covenant, in a form provided by the Village, providing that any accessory structures must be removed at the owner's expense at the expiration of this allowance or else may be removed by the Village at the owner's expense. The covenant shall further provide that any fees owed to the Village pursuant to the covenant that have not been paid within thirty (30) days following the mailing of a written demand for payment may be imposed as a lien against the property and may be foreclosed in the manner provided for mortgages or mechanics' liens under Illinois law.
G. Accessory structures or buildings erected or altered on any lot in any zoning district that exceed one thousand (1,000) square feet in total floor area shall be subject to the principal structure setback requirements for such zoning district.
H. No garage hereafter erected on any lot located in the R-1, R-2, R-3, R-4, or R-5 Residence District shall have vehicular doors that extend along the front of the lot for a distance greater than fifty percent (50%) of the width of the principal building, or eighteen feet (18'), whichever is less.
