Sec. 2100.18. Housing accommodations which are not the primary residence of the tenant in possession

Any housing accommodations on or after May 1, 1972 which are not occupied by the tenant in possession as his primary residence shall continue to be subject to rent control unless the administrator issues an order decontrolling such accommodation, which the administrator shall do upon application by the landlord, whenever it is established by any facts and circumstances which, in the judgment of the administrator, may have a bearing upon the question of residence, that the tenant maintains his primary residence at some place other than at such housing accommodation.
