Cal. Civ. Code § 55
Wainscoting
Operative Text
§ 55. Wainscoting. 1. Whenever the surface of walls, partitions or ceilings in any apartment or suite of rooms of any non-fireproof multiple dwelling is covered, sheathed or wainscoted wholly or in part after April eighteenth, nineteen hundred twenty-nine, such covering shall be backed solidly with plaster. In fireproof multiple dwellings such covering shall be backed solidly and continuously or filled with incombustible material. In the case of walls and partitions in fireproof dwellings, such backing and filling shall extend to the fireproof floor construction and in non-fireproof dwellings to the floor beams. All such backing and filling shall be fire-stopped. 2. No wood wainscoting other than fireproofed wood complying with the provisions of section fifty-eight shall be erected in any public hall, stair or shaft of any multiple dwelling.
N.Y. Mult. Dwell. Law § 55 governs how wall, partition, and ceiling coverings—commonly called wainscoting—must be installed in multiple dwellings. In non-fireproof buildings, any such covering applied after April 18, 1929 must be backed solidly with plaster, while fireproof buildings require solid, continuous backing or filling with noncombustible material. The backing or filling must reach down to the floor construction or floor beams depending on building type, and all such assemblies must be fire-stopped. Additionally, untreated wood wainscoting is prohibited in public halls, stairways, and shafts of any multiple dwelling, regardless of building type.

Property owners and managers operating multiple dwellings in New York should be aware that § 55 of the Multiple Dwelling Law sets specific construction standards for any wall, partition, or ceiling coverings installed in their buildings. Compliant operators ensure that wainscoting in non-fireproof buildings is solidly plaster-backed and that fireproof buildings use noncombustible fill or backing extending fully to the appropriate floor construction, with proper fire-stopping throughout. In common areas such as public halls and stairways, operators generally use only fireproofed wood that meets the standards referenced in section fifty-eight, rather than untreated wood materials.

Under N.Y. Mult. Dwell. Law § 55, tenants living in multiple dwellings have an interest in knowing that the law sets fire-safety construction standards for wall and ceiling coverings in their building. If wainscoting or similar coverings appear to have been installed without proper backing, fire-stopping, or with untreated wood in common areas, this may represent a code violation that can be reported to the New York City Department of Buildings or the relevant local housing authority. Tenants who believe such a violation exists may also consider consulting a tenant-rights organization or raising the issue as part of a broader housing maintenance complaint.
