Oswego, N.Y., Code of Ordinances ch. 149 § 149-12
Habitable space
Operative Text
A. Size. (1) Habitable space shall have a minimum ceiling height of seven feet, six inches over 50% of the floor area; and the floor area where the ceiling height is less than five feet shall not be considered in computing floor area. (2) A dwelling unit shall contain at least one habitable room having a minimum of 150 square feet of floor area and a minimum horizontal dimension of 10 feet. (3) Kitchens shall have a minimum of 60 square feet of floor area, and other habitable spaces shall contain not less than 80 square feet of floor area and shall have a minimum horizontal dimension of seven feet. (4) Every alcove less than 60 square feet in area, except a cooking space or foyer, shall be deemed to be part of a habitable room. The area of the opening in the dividing partition between the alcove and the room shall be at least 80% of the wall area of such partition, measured on the alcove side, but not less than 40 square feet. The depth of such alcove shall not exceed half its width. The floor area of the alcove shall be added to the floor area of the room in determining light and ventilation requirements for the room. An alcove with an area of 60 square feet or more, but less than the required area of a habitable room, shall be separately lighted and ventilated as required for habitable space. B. Basements. Basements shall not be deemed habitable space where required windows are located only on one wall and the depth of the basement space exceeds four times its clear height. C. Light and ventilation. (1) Habitable space shall be provided with: (a) Natural light through one or more windows, skylight, transparent or translucent panels, or any combinations thereof, that face directly on legal open spaces at least six inches above the adjoining finished grade or are above the roof. The amount of light shall be equivalent to that transmitted through clear glass equal in area to 10% of the floor area of the habitable space. (b) Artificial light. (c) Natural ventilation through openable parts of windows or other openings in exterior walls that face legal open spaces above the adjoining finished grade or above a roof, or through openable parts of skylights, providing total clear ventilation area equal to not less than 5%) of the total floor area of each habitable space. (2) Habitable space may also be provided with mechanical ventilation, in addition to natural ventilation. D. Miscellaneous requirements. (1) Dwelling units shall be separated from each other and from other spaces outside the dwelling unit. (2) Sleeping rooms within dwellings units shall be separated from each other and from other spaces outside the sleeping rooms to provide privacy. (3) Lodging units shall be separated from each other and from other spaces outside the lodging units. (4) A communal kitchen or dining room in a lodging house shall be accessible to the occupants sharing such kitchen or dining room without going through a dwelling unit or lodging unit of another occupant.
Section 149-12 of Oswego's Code of Ordinances establishes minimum physical standards for spaces classified as "habitable" in residential dwellings. These standards cover ceiling heights, floor area dimensions, natural and artificial light, ventilation, and the separation of dwelling and sleeping units from one another. Spaces that fall short of these measurements — such as low-ceilinged basements or undersized rooms — may not legally qualify as habitable space, affecting how a unit's livable area is calculated and represented.
Plain English — not legal advice.
Operators of residential rental properties in Oswego must ensure that every unit offered for occupancy meets the dimensional and environmental thresholds set out in § 149-12, including minimum ceiling heights, room sizes, and window-to-floor-area ratios for light and ventilation. Compliant operators typically document room measurements, verify that natural light sources face legal open spaces, and confirm that dwelling and sleeping units are properly separated before renting. Kitchens, alcoves, and basement spaces each carry their own specific requirements under this section that should be reviewed during property inspections or before listing a unit.

Under § 149-12, tenants in Oswego have a right to occupy dwelling units that meet defined minimums for ceiling height, room size, natural light, and ventilation, and where sleeping areas provide adequate privacy through proper separation. If a rented space appears to fall below these standards — for example, a basement room with insufficient ceiling clearance or a bedroom lacking required window area — that condition may constitute a code violation. Tenants can report potential violations to the local code enforcement office, raise the issue as a defense in relevant housing proceedings, or consult a tenant-rights organization for guidance on available options.
