Hamden, Conn., Mun. Code Ch. 152 § 152.80
EXTERMINATION OF INSECTS, RODENTS
Operative Text
Every occupant of a dwelling containing a single dwelling unit shall be responsible for the extermination of any insects, rodents, or other pests therein or on the premises. Every occupant of a dwelling unit in a dwelling containing more than one dwelling unit shall be responsible for the extermination whenever his dwelling unit is the only one infested. Notwithstanding the foregoing provisions of this section, whenever infestation is caused by failure of the owner to maintain a dwelling in a ratproof or reasonably insectproof condition, extermination shall be the responsibility of the owner. Whenever infestation exists in 2 or more of the dwelling units in any dwelling, or in the shared or public parts of any dwelling containing 2 or more dwelling units, extermination thereof shall be the responsibility of the owner. (Adopted 9-5-67) Penalty, see § 152.199
Under Hamden Ch. 152 § 152.80, responsibility for pest extermination in a dwelling depends on the structure and scope of the infestation. In a single-unit dwelling, the occupant bears full responsibility for extermination. In multi-unit buildings, a tenant is responsible only when the infestation is confined to their unit alone; once pests are found in two or more units, in shared spaces, or when the infestation stems from the owner's failure to maintain a ratproof or insectproof structure, the responsibility shifts to the property owner.
Plain English — not legal advice.
Property owners and managers operating under Hamden Ch. 152 § 152.80 generally maintain their buildings in a ratproof and reasonably insectproof condition to avoid bearing extermination responsibility. Compliant operators routinely inspect shared areas, hallways, basements, and building exteriors, and arrange professional extermination whenever pests are found in two or more units or in common spaces. Owners also address structural deficiencies—such as gaps, cracks, or deteriorated seals—that could allow pest entry, since failure to do so shifts extermination liability to the owner regardless of where the infestation originates.

Under Hamden Ch. 152 § 152.80, tenants in single-unit dwellings are generally responsible for pest extermination, as are tenants in multi-unit buildings when the infestation is limited solely to their own unit. However, when an infestation spreads to two or more units, appears in shared or common areas, or results from the owner's failure to keep the building structurally pest-resistant, the law places extermination responsibility on the owner. Tenants who believe their situation falls under the owner's responsibility may consider documenting the infestation, notifying the owner in writing, and reaching out to Hamden's housing enforcement office or a local tenant-rights organization to understand available complaint and enforcement options under § 152.199.
