(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 tract area shall be a minimum of 7,000 square feet with a minimum tract width of 70 feet (where sanitary sewers are available) for single-family detached and single-family attached uses. For a quadruplex, (four units with two common walls), the minimum tract area is 14,000 square feet. For multiple family uses and “group quarters” uses (Use Unit 7), the minimum tract area is 10,000 square feet with a minimum tract width of 100 feet.
(b) It is assumed that there is a minimum of three townhouses per structure with a 70-foot tract width; thus, the minimum lot width is 20 feet (with public sewers) for townhouses. Therefore, the interior lot of the three townhouses has a minimum lot area of 2,000 square feet and the exterior townhouse lots are a minimum of 2,500 square feet.
(c) It is assumed that there are two units per structure in a duplex with a 70-foot tract width; thus, the minimum lot width is 35 feet (with public sewers) with one common wall for duplexes. Therefore, the minimum lot area is 3,500 square feet per dwelling unit (where sanitary sewers are available).
(d) It is assumed that there are four units per structure in a quadruplex with a 70-foot tract width; thus, the minimum lot width is 20 feet (with public sewers) for a quadruplex with two common walls. Therefore, the minimum lot area is 3,500 square feet per dwelling unit (where sanitary sewers are available).
(e) Where no sanitary sewers are available and disposal is by soil absorption, the minimum lot area shall be one acre per single-family detached dwelling and one acre per duplex structure. The lot size for townhouse, quadruplex, multi-family structures and “group quarters” (Use Unit 7) structures shall not be less than one acre, and the Posey County Health Department may require a larger lot size. For all residential uses, the Posey County Health Department may require a larger lot for any type of residential use.
(2) Non-residential use.
(a) The lot area shall be at least 10,000 square feet with a minimum width of 100 feet.
(b) Where no sanitary sewers are available and disposal is by soil absorption, minimum lot of the 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 or tract for single-family detached dwelling, townhouse structure, single-family attached structure, multiple family structure and “group quarters” structure (Use Unit 7), 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 the there is no dedicated roadway right-of-way, the front yard (or corner 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 yard.
(a) Every lot used for a single-family detached dwelling or every tract used for a single-family attached structure shall have a side yard not less than five feet in depth. The interior lot (or unit) of a townhouse structure with two common walls has no side yard requirement. The adjoining lots of a duplex with one common wall or adjoining lots of a zero lot-line development have no side yard requirement. The adjoining portion of lots of quadruplex structure with two common walls has no side year requirements.
(b) Every lot used for non-residential use shall have a side yard of 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 office 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.
(a) Every lot or tract for a residential use shall have a rear yard of not less than 20 feet in depth. For a quadruplex, the rear yard must be observed for the tract holding the quadruplex structure, but is not observed for the adjoining portion of lots where a common wall exists between abutting units.
(b) Every lot used for a non-residential use shall have a rear yard of 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 office 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 2.5 stories, not to exceed 35 feet.
(D) Lot coverage. The combined area occupied by all principal and accessory buildings shall not exceed 50% of the area of the lot.
(E) Minimum floor area.
(1) Minimum livable floor area for a single-family detached dwelling unit shall be 950 square feet and a minimum of 23 feet wide.
(2) Minimum livable floor area for a single-family attached (townhouse, duplex, zero lot-line or quadruplex) shall be 650 square feet per dwelling unit, total of 1,950 square feet for a townhouse structure (assuming three units) total 1,300 square feet per duplex structure (two units) total of 650 square feet per zero lot-line unit, and total of 2,600 square feet per quadruplex structure (four units).
(3) Minimum livable floor area for a multiple-family dwelling shall be 400 square feet for an efficiency apartment, 500 square feet for a one-bedroom apartment, 600 square feet for a two-bedroom apartment, and 700 for a three-bedroom apartment.
(F) Minimum lot area per dwelling unit. The minimum lot area per dwelling unit shall be 1,500 square feet for multiple family uses and other residential uses in the Use Group 7 containing multiple dwelling units.
(G) Floor area ratio. The floor area ratio shall not exceed 0.50.
(H) Dwelling unit density. The maximum number of dwelling units per acre is 29.04.
