Cal. Civ. Code § 5:10-16.2
Natural ventilation
Operative Text
(a) Every habitable room, bathroom, toilet room or enclosed kitchenette shall have a means of natural ventilation unless there is supplied some other device affording adequate ventilation and exchange of air. Natural ventilation as required hereunder shall be directly to the exterior through an opening of at least three square feet or through a porch having access and exposure to fresh air from the exterior. The total of openable window or skylight area in each such room shall be equal to at least 50 percent of the minimum window or skylight area required for natural light under N.J.A.C. 5:10-16.1. (b) Every such window or skylight shall be equipped with the necessary hardware or other means so that it can be readily opened and closed by occupants from the interior of the dwelling space.
Under N.J.A.C. § 5:10-16.2, every habitable room, bathroom, toilet room, and enclosed kitchenette in a dwelling must have a way to bring in fresh air from outside. This can be achieved through natural ventilation — specifically, openings of at least three square feet that connect directly to the exterior — or through an approved mechanical ventilation alternative. Any windows or skylights used for this purpose must have openable area equal to at least half of the minimum required for natural light under N.J.A.C. 5:10-16.1, and they must be operable by occupants from inside the dwelling.
Plain English — not legal advice.
Operators of residential properties in New Jersey should ensure that every habitable room, bathroom, toilet room, and enclosed kitchenette meets the ventilation standards set out in N.J.A.C. § 5:10-16.2. Compliant properties typically feature windows or skylights with sufficient openable area — at least 50 percent of the minimum light-area requirement — or an approved mechanical ventilation system where natural ventilation is not feasible. Hardware on all windows and skylights should be maintained in working order so that occupants can open and close them without assistance from the exterior.

N.J.A.C. § 5:10-16.2 gives occupants the right to adequate ventilation in every habitable room, bathroom, toilet room, and enclosed kitchenette, including windows or skylights that can be opened and closed from inside the unit. If a rental unit lacks functioning ventilation openings or the required hardware, this may constitute a housing code violation that can be reported to the local municipal housing or code enforcement office in New Jersey. Tenant-rights organizations can help residents understand how to document ventilation deficiencies and what remedies may be available under state housing regulations.
