D.
Factors.
The determination of whether a group of unrelated persons living together are a Family shall be based on such of the following factors as may be known to the Building Commissioner, upon information and belief or otherwise. The presence or absence of any single factor is not necessarily determinative of whether the unit constitutes a Family.
1.
The following factors shall be prima facie evidence that the group of persons living together constitutes a Family:
a.
The same group of persons, or a majority of them, has resided together at a different location for a period of at least 6 months or at the present location for at least 12 months.
b.
One or two members of the group have executed the lease for the entire premises, including the entire rental obligation, and there are no sub-lease, hold-harmless or other written arrangements to pro-rate the rent or recover the rent from other members of the group.
2.
The following factors shall be prima facie evidence that the group of persons does not constitute a Family:
a.
The group includes more than two unrelated individuals.
b.
Individual members of the group have entered into separate leases for the same premises, or parts thereof, with the obligation under each lease constituting only a portion of the total periodic rent payment due to the landlord for occupancy of the premises.
c.
The premises are equipped with combination or key-operated locks on individual rooms or with other means by which one member of the group may prevent other members of the group from entering her or his room or portion of the premises when she or he is not physically present. (Deadbolts, chains or other locking devices operated only from inside the room shall not be considered as evidence of the status of the group.)
3.
The following additional factors shall be considered, to the extent known or applicable, in determining whether the group of persons constitutes a Family:
a.
Voter registration. Voter registration by a majority of the eligible members of the group listing the address of the group's dwelling shall be considered evidence in support of the proposition that the group is a Family. Voter registration listing other addresses by a majority of the adult members of the group, or by a majority of those actually registered to vote shall be considered evidence negating the proposition that the group is a Family.
b.
Driver’s licenses. Drivers' licenses held by a majority of the adult members of the group listing the address of the group's dwelling shall be considered evidence in support of the proposition that the group is a Family. Drivers' licenses listing other addresses by a majority of the adult members of the group, or by a majority of those actually holding such licenses shall be considered evidence negating the proposition that the group is a Family.
