Every occupant of a dwelling containing a single dwelling unit, or an occupant of a nonresidential building containing a single unit, shall be responsible for the extermination of vermin infestations and/or rodents on the premises. Every occupant of a nonresidential building containing more than one unit shall be responsible for the extermination whenever their unit is the only one infested. Notwithstanding, however, whenever an infestation is caused by the failure of the owner to maintain a building in a reasonable rodent proof, or reasonable vermin proof, condition, extermination shall be the responsibility of the owner. Whenever extermination is the responsibility of the owner, the extermination must be performed by a licensed pest control contractor.
