Cal. Civ. Code § 58
Incombustible materials
Operative Text
§ 58. Incombustible materials. Except as may be specifically provided otherwise in this chapter, all required incombustible materials, including fireproofed wood, shall be capable of withstanding successfully standard fire tests as prescribed by the building code. In the absence of any such prescribed requirements, the department shall have the power to make supplementary regulations relative to standard fire tests for incombustible materials.
N.Y. Mult. Dwell. Law § 58 establishes a baseline performance standard for incombustible materials used in multiple dwellings, including fireproofed wood. Any such material must be able to pass standard fire tests as defined by the applicable building code. Where the building code does not specify those testing requirements, the relevant department is authorized to issue its own supplementary regulations to fill that gap.

Under N.Y. Mult. Dwell. Law § 58, operators of multiple dwellings generally ensure that any incombustible materials—including fireproofed wood—used in construction or renovation meet the fire-test standards set by the building code. Compliant operators typically verify that suppliers and contractors can document that materials satisfy those standards before installation. When local building code requirements are silent on specific fire tests, operators look to any supplementary regulations the department may have issued under this section.

N.Y. Mult. Dwell. Law § 58 gives tenants a basis to expect that incombustible materials in their building meet established fire-resistance standards. If a tenant has reason to believe that substandard materials were used, general enforcement paths include raising the issue with the local building or housing department, which holds oversight authority under this provision. Tenant-rights organizations can help residents understand how this section interacts with broader housing safety requirements and what complaint processes may be available.
