(a) Conversion of Single-Family Dwelling to a Two-Family or Multiple Family Dwelling. An existing dwelling may be converted to contain an additional dwelling unit in the R-6 Two-Family Residential district or additional dwelling units in the R-7 Multi-Family Residential or OR-1 Office-Residential districts, provided there is:
(1) A minimum gross floor area in the dwelling before conversion, exclusive of cellar or basement of two thousand (2,000) square feet.
(2) A minimum of one thousand (1,000) square feet of gross floor area provided for each dwelling unit after conversion.
(3) Before conversion, compliance with all lot size and bulk regulations imposed in the zoning district in which the dwelling is located.
(4) After conversion, compliance with all lot size and bulk regulations imposed in the zoning district in which the dwelling is located.
(5) After conversion, the converted dwelling shall retain the appearance of a single-family dwelling with no major structural alterations to the exterior of the building other than to provide the required means of egress from dwelling units. All fire escapes or stairways leading to a second floor must be completely enclosed within the converted building.
(b) Residential Conversion of Industrial Structures.
(1) Purpose. To permit the conversion of older non-residential buildings within the M-2 Industrial District found within the older central built-up core of the community to allow adaptive reuse of older structures within the central portion of the community that have limited or no potential for continued industrial use.
(2) The Planning Commission may permit conversion of non-residential structures to partial residential use subject to the following:
A. All applicable provisions of the Troy Building Code must be followed.
B. The Planning Commission may limit the number of residential units within the structure based upon available parking area, capacity of the road network to accommodate the traffic, utility capacities, and character of the surrounding neighborhood.
C. All dwelling units must have a minimum residential floor area of six hundred (600) square feet.
D. Where at least fifteen (15) dwelling units are provided within a building, which can accommodate recreational use of the roof, a minimum of thirty (30) percent of the roof area shall be designed to provide open space for residents of such building, unless similar space provided elsewhere on the property. For each additional dwelling unit over fifteen (15), an additional one hundred (100) square feet of roof area shall be devoted to open space use, up to a maximum of fifty (50) percent of the total roof area.
(Ord. 15-2009. Passed 6-15-09.)
E. Prior to authorizing residential use within a structure in the M-2 Industrial Zoning District, the Planning Commission may consider the following:
1. Whether conversion will harm the industrial sector of Troy's economy.
2. Whether the conversion will preempt space necessary for industrial uses, considering the availability of alternate space for industrial use. (Ord. 25-2011. Passed 12-19-11.)
F. Upon the voluntary discontinuance of such residential use in an industrial building for a period of one hundred eighty (180) days no such use shall be reestablished.
G. The conversion of non-residential structures to full residential use shall require Planned Development approval.
