Cal. Civ. Code § 30
Cellar ceilings
Operative Text
§ 30. Cellar ceilings. In every such dwelling three stories or more in height the ceiling of the cellar, or of the lowest story if there be no cellar, shall be fire-retarded, or be equipped with a sprinkler system, unless such ceiling has already been plastered to the satisfaction of the department.
Under N.Y. Mult. Resid. Law § 30, residential dwellings of three stories or more must have the ceiling of their cellar—or lowest story if no cellar exists—treated to resist fire spread. This requirement is satisfied by applying fire-retardant materials, installing a sprinkler system, or having the ceiling already plastered to the satisfaction of the relevant department. The rule establishes a baseline fire-safety standard for the lowest level of taller multi-residence buildings.
Plain English — not legal advice.
Operators of multiple dwellings three stories or higher should ensure that the cellar ceiling, or lowest-story ceiling where no cellar exists, meets the fire-resistance standards outlined in N.Y. Mult. Resid. Law § 30. Compliant buildings typically achieve this through fire-retardant treatment, a sprinkler system, or existing plaster that has been accepted by the inspecting department. Owners generally document any departmental approvals of plastered ceilings to demonstrate ongoing compliance during inspections.

N.Y. Mult. Resid. Law § 30 establishes a right to live in a building where the cellar or lowest-story ceiling meets fire-safety standards in dwellings of three or more stories. If a tenant believes this requirement is not being met, general enforcement paths include filing a complaint with the local housing or building department, raising the violation in a housing court proceeding, or reaching out to a tenant-rights organization for guidance. Keeping notes and photographs of conditions in common areas like cellars can help document concerns when pursuing any of these avenues.
