Cal. Civ. Code § 137
Business uses
Operative Text
§ 137. Business uses. When business is conducted in a non-fireproof multiple dwelling, the ceiling of the business space shall be covered with fire-resistive materials or be equipped with a sprinkler system.
Under N.Y. Mult. Resid. Law § 137, when a non-fireproof multiple dwelling contains space used for business purposes, the ceiling of that business area must be protected—either by being covered with fire-resistive materials or by having a sprinkler system installed. This rule is a fire-safety requirement aimed at reducing the spread of fire in mixed-use residential buildings that lack full fireproof construction. It applies to the physical condition of the building itself, not to the nature of the business being conducted.
Plain English — not legal advice.
Operators of non-fireproof multiple dwellings that include business spaces should be aware that N.Y. Mult. Resid. Law § 137 establishes a specific ceiling-protection standard for those areas. A compliant building owner generally ensures that the ceiling of any business space is either finished with fire-resistive materials or outfitted with a functioning sprinkler system before such space is occupied for commercial use. Routine inspections and documentation of the ceiling's fire-resistive treatment or sprinkler coverage help demonstrate ongoing compliance with this provision.

N.Y. Mult. Resid. Law § 137 establishes a fire-safety standard that protects occupants of non-fireproof multiple dwellings where business activity takes place. Tenants who believe a building's business-space ceiling lacks the required fire-resistive covering or sprinkler system may report the condition to the local housing or building code enforcement agency. Tenant-rights organizations can help residents understand how a violation of this provision might be raised or pursued through available administrative or legal channels.
