(A) Area. Every lot upon which a structure is hereafter erected shall front onto a dedicated street or public right-of-way, and shall conform to the following minimum lot area and width requirements.
(1) Residential use.
(a) The lot area shall be a minimum of 7,000 square feet with a minimum width of 70 feet (where sanitary sewers are available).
(b) Where no public sewers are available and disposal is by soil absorption, the minimum lot area shall be one acre. The Posey County Health Department may require a larger lot.
(2) Non-residential use.
(a) The lot area shall be a minimum of 10,000 square feet with a minimum width of 100 feet (where sanitary sewers are available).
(b) Where no public sanitary sewers are available and disposal is by soil absorption, minimum lot area shall be one acre. The Posey County Health Department may require a larger lot.
(B) Yards.
(1) Front yard and street side yard.
(a) Every lot used for a single-family detached dwelling shall have a front yard (or street side yard) not less than 25 feet in depth. The front yard (or street side yard) may be more or less than the 25-foot minimum depending on the predominant front yard (or street side yard) setback of existing structures along the blockface. If only one lot on the blockface is developed, the front yard (or street side yard) should be an average of the 25-foot setback and the existing structure setback. When the proposed structure falls between two developed lots, the front yard setback should be the average of the two abutting lot structure setbacks.
(b) Every lot used for a non-residential use shall have a front yard (or corner lot side yard) not less than 25 feet in depth.
(c) If there is no dedicated roadway right-of-way, the front yard (or comer lot side yard) setback from the center of the roadway is 25 feet plus one-half the right-of-way width of the applicable roadway functional class as if the roadway had been dedicated (adding 25 feet for a “local street”, 40 feet for a “collector” or “secondary arterial”, 60 feet for a “primary arterial”, and 75 feet for a “divided primary arterial”).
(2) Side yards.
(a) Every lot used for a single-family detached dwelling shall have a side yard not less than five feet in depth.
(b) Every lot used for a non-residential use shall have a side yard not less than ten feet in depth. However, when a non-residential use by right or special exception abuts a residential or office district, the minimum side yard requirement in the RS or R-1 District of ten feet shall be increased by one foot for each foot of building height exceeding 18 feet, but the required side yard shall not exceed 25 feet.
(3) Rear yard.
(c) Every lot used for a one-family dwelling shall have a rear yard not less than 25 feet in depth.
(d) Every lot used for a non-residential use shall have a rear yard not less than ten feet in depth. However, when a non-residential use by right or special exception abuts a residential or office district, the minimum rear yard requirement in the A District of ten feet shall be increased by one foot for each foot of building height exceeding 18 feet, but the required rear yard shall not exceed 25 feet.
(C) Height. No building or structure or part thereof shall be erected or altered to a height exceeding two and one-half stories, or 35 feet.
(D) Lot coverage. The combined area occupied by all principal and accessory buildings shall not exceed 30% of the area of the lot.
(E) Minimum floor area. A one-family dwelling shall have a minimum livable floor area of 950 square feet and shall be a minimum of 23 feet wide.
