No trailer shall be parked on any premises other than an approved trailer park, and no person shall occupy any trailer parked on any premises other than an approved trailer park; excepting, however, that any trailer owned by the owner or occupant of any premises may be parked on such premises owned or occupied by such person, and a trailer owned by a guest of such owner or occupant of any premises may be parked on such premises and occupied by such guest, provided, however, that altogether any and all such parkings and occupancies on any such property by any guest or guests shall not exceed a total of fifteen days in any calendar year. The owner or occupant of any such premises, immediately after the entry on such premises, of any trailer owned by a guest, shall report to the building department the date of such entry; the registration number of such trailer, and immediately after the departure of such trailer shall report the date of such departure, and failure of such owner or occupant of any such premises to make any such report shall constitute prima facie evidence of the existence of such parking and occupancy for a period of fifteen days in such calendar year.
