(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.
(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.
(c) 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 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 or tract used for a single-family detached dwelling or single-family attached 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 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 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 RT 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 used for a one-family dwelling (attached or detached) shall have a rear yard not less than 20 feet in depth.
(b) 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 RT 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.

(2) A single-family attached dwelling shall have a minimum livable floor area of 650 square feet and shall be a minimum dwelling unit width of 20 feet wide.

(G) Dwelling unit density. The maximum number of dwelling units per acre is 12.446.
