A. It is the purpose of this Code to discourage the conversion of existing dwellings originally designed for occupancy by two families or less to occupancy by more than two families when such conversion is likely to lead to overcrowding, to lack of privacy, to lack of sufficient light and air, to unsafe or unsanitary living conditions or to inadequate provisions for off-street parking and open space.
B. Such conversions shall be consistent with the purposes or other applicable provisions of this Code, housing and building codes and fire codes and utility programs.
C. In connection with such conversion there shall be no evidence of change in the structure to indicate the extra dwelling units, except as may be required by the aforementioned codes and programs. All fire escapes or stairways leading to a second or higher floor shall be completely enclosed within the converted building and no dwelling shall be so converted unless in connection therewith it be placed in a reasonable state of repair.
D. In cases of question as to the applicability of these standards, such proposed conversion shall be deemed an exception and placed before the Board in accordance with the requirements in Section 5.
