Cal. Civ. Code § 170
Water supply
Operative Text
§ 170. Water supply. The owner shall provide proper appliances to receive and distribute in such dwelling an adequate supply of water obtained from the public water supply system or from a source approved by the public health officer having jurisdiction at all times when the building is occupied and during all hours and hot water between six o'clock in the morning and midnight.
New York Multiple Residence Law § 170 requires that any occupied multiple dwelling be supplied with an adequate and continuous flow of water at all times, drawn from either a public water system or a source approved by the relevant public health authority. Beyond general water availability, the rule specifically mandates that hot water be available during the hours of 6:00 a.m. through midnight. The building owner bears responsibility for installing and maintaining the equipment necessary to receive and distribute this water supply throughout the dwelling.
Plain English — not legal advice.
Under N.Y. Mult. Resid. Law § 170, compliant building operators maintain functioning plumbing infrastructure connected to an approved water source and ensure that water is available continuously whenever the building is occupied. For hot water specifically, operators keep systems operational and capable of delivering hot water to residents during the prescribed window of 6:00 a.m. to midnight every day. Routine inspection of boilers, water heaters, and distribution equipment is a common practice among owners seeking to stay ahead of potential violations under this section.

N.Y. Mult. Resid. Law § 170 establishes a right to continuous cold water and to hot water between 6:00 a.m. and midnight in any occupied multiple dwelling. If water service is interrupted or hot water is consistently unavailable during those hours, tenants may have grounds to report the condition to the local housing or building code enforcement agency, or to raise the violation in a housing court proceeding. Tenant-rights organizations and legal aid offices can help residents understand the range of options available under this provision.
