(a)

Front yards shall remain unoccupied except for landscaping, signs, fences, driveways and off-street parking access aisles.

(b)

Supplemental front yard setback regulations.

(1)

When dwellings erected on one or both sides of a lot have front yard setbacks less than the required front yard setback, the required front yard setback of the lot may be reduced to no less than the average front setback of the existing developed front yards on lots within 100 feet of, and on the same block as, the subject lot, or ten feet, whichever is greater. This averaging may not be used for locating new accessory structures.

(2)

On corner and through lots, those yards having frontage on streets shall be considered front yards and the front yard setback regulations applicable in the zoning district in which such lots are located shall apply. Both yards having frontage may be averaged in accordance with this section.

(c)

Lots having frontage on the Saginaw River.

(1)

Buildings, excluding boathouses, erected on lots that have frontage on the Saginaw River shall be set back at least 25 feet from the water's edge.

(2)

If dwellings on both waterfront lots adjoining a vacant waterfront lot are set back less than 25 but more than ten feet from the water's edge, the setback may be reduced to the average setback of those dwellings. If one of those lots is vacant and the other occupied by a dwelling which is set back less than 25 feet from the water's edge, the setback may be reduced to the average setback of that dwelling and 25-foot setback required by a above, though in no instance shall the setback be less than ten feet.

(3)

Michigan Department of Environmental Quality (MDEQ) flood plain regulations, Army Corps of Engineers regulations, and standards applicable to the construction of buildings and establishment of uses in coastal zone management areas administered by the MDEQ land and water management division and other state and federal regulations may require greater setbacks than required in section 122-303(b). In such cases, those agencies' regulations and standards shall apply.

(d)

The floor area of basements, attached garages, enclosed or unenclosed porches and decks shall not be included when calculating minimum floor area of dwellings.

(e)

See section 122-306(1) for minimum lot area regulations.

(f)

Apartment buildings three or more stories in height that adjoin single- or two-family residential zoning districts shall be set back at least 15 feet from any side lot line.

(g)

See section 122-306(3) for required distance between individual buildings.

(h)

See section 122-306(2) for minimum floor area regulations.
