Accessory buildings and structures, except as otherwise permitted in this ordinance, shall be subject to the following regulations:
A. Where the accessory building is structurally attached to a principal building, except as provided in section 28.10, it shall conform to all regulations of this ordinance applicable to the principal building.
B. A detached accessory building or structure shall not be located in the front or the required side yards except as provided in this division. No detached accessory building (excluding pools) shall be located closer than ten feet to any principal building or deck. Detached accessory buildings are permitted to be located in the required rear yard provided they are not closer than three feet to any lot line. In the case of a through lot, a detached accessory building or structure shall not be located in any required rear yard that abuts the front yard of an adjacent lot. In the case of a corner lot, accessory buildings (excluding swimming pools and sheds) shall not be located in either required front yard. Swimming pools, and sheds not exceeding 200 square feet, when located on a corner lot, may extend ten feet into the side street front yard setback, provided there is no paved access to the property line or curb cut. Sheds not exceeding 200 square feet, when located on a corner lot which has a six feet sight-obscuring privacy fence or six feet high sight-obscuring landscaping along the front setback line of the side street front yard, may extend 27 feet into the side street front yard setback of the corner lot, or 37 feet into the side street front yard setback of a corner lot if on a major thoroughfare, provided there is no paved access to the property line or curb cut. If a shed is installed at a location which is more than 10 feet into the front yard setback of the side street front yard of the corner lot as a result of the existence of a 6' sight-obscuring privacy fence or six feet high sight-obscuring landscaping, a six feet sight-obscuring privacy fence or six feet high sight-obscuring landscaping shall be maintained at all times. A notice of this condition shall be recorded against the property at the time the permit is issued for the shed encroaching into the front yard setback whenever the sight-obscuring fence or landscaping is required due to the placement of the shed within the required yard. In no instance shall an accessory structure be located within a dedicated easement.
C. Accessory buildings and structures shall not exceed one story, or 15 feet in height, in any residential or commercial zoning district. Accessory buildings with a floor area over 50 square feet shall be installed upon a concrete slab floor that is at least 3½ inches thick and in compliance with all applicable requirements of the Michigan Building Code or Michigan Residential Building Code. Sheds shall not exceed ten feet in height on a lot of one-fourth acre or less located in any residential zoning district. Sheds shall not have openings or doors exceeding six feet in width.

1. A satellite dish antenna that is designed to receive direct satellite service, including direct-to-home satellite service, that is one meter or less in diameter shall be permitted without a zoning compliance permit, unless it is attached to a mast of greater than 12 feet in height. If the mast to which it is attached exceeds 12 feet in height, then special approval land use by the Planning Commission under Article 25 shall be required;
2. A satellite dish antenna that is designed to receive video programming services via multi- point distribution services, including multichannel multi-point distribution services, instruction television fixed services and local multipoint services and that is one meter or less in diameter or diagonal measurement shall be permitted without a zoning compliance permit, unless it is attached to a mast of greater than 12 feet in height.

Such a structure shall not, however, be erected so as to injure the roof covering, and when removed from the roof, the roof covering shall be repaired to maintain weather and water tightness. The installation of any antenna structure mounted on the roof of a building shall not be erected nearer to the lot line than the total height of the antenna structure above the roof, nor shall such antenna structure be erected near electric power lines or encroach upon any street or other public space;
5. Satellite earth stations more than one meter in diameter located in a residential district shall require special land use approval by the Planning Commission under Article 25;
6. Satellite earth stations more than two meters in diameter located in an area where commercial or industrial uses are generally permitted shall require special approval land use by the Planning Commission under Article 25;

Any structure covered by this section shall not be located in any front or required side yard setback.
I. In nonresidential zoning districts, accessory buildings may occupy any of the ground area which the principal building is permitted to cover. Accessory buildings in nonresidential zoning districts that abut nonresidential zoned properties shall be regulated according to the provisions of section 28.00, A-G. Minor accessory buildings, such as buildings for guard shelters and gate houses, may be located in the front or side yard in nonresidential districts, upon site plan approval. All such buildings or structures shall be architecturally and aesthetically compatible with the principal building. All such devices shall be located and landscaped to reduce the visual impact from surrounding properties and from public streets.
