This code shall be known and may be cited as the "New York City Plumbing Code," "NYCPC" or "PC." All section numbers in this code shall be deemed to be preceded by the designation "PC."
The provisions of this code shall apply to the erection, installation, alteration, repair, relocation, replacement, addition to, use or maintenance of plumbing systems. This code shall also regulate nonflammable medical gas, inhalation anesthetic, vacuum piping, nonmedical oxygen systems and sanitary and condensate vacuum collection systems. The installation of fuel-gas distribution piping and equipment, fuel gas-fired water heaters, and water heater venting systems shall be regulated by the New York City Fuel Gas Code.
The purpose of this code is to provide minimum standards to safeguard life or limb, health, property, public welfare and the environment by regulating and controlling the design, construction, installation, quality of materials, location, operation and maintenance or use of plumbing systems.
If a section, subsection, sentence, clause or phrase of this code is, for any reason, held to be unconstitutional, such decision shall not affect the validity of the remaining portions of this code.
Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall govern. Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern.
Except as otherwise specifically provided, plumbing systems lawfully in existence at the time of the adoption or a subsequent amendment of this code shall be permitted to have their use and maintenance continued if the use, maintenance or repair is in accordance with the original design and no hazard to life, health or property is created by such plumbing system.
Additions, alterations, renovations or repairs related to building or structural issues shall be governed by Chapter 1 of Title 28 of the Administrative Code, the New York City Building Code and the 1968 Building Code, as applicable.
For existing buildings, a reference to a section of the New York City Building Code in this code shall also be deemed to refer to the equivalent provision of the 1968 Building Code, as applicable in accordance with Chapter 1 of Title 28 of the Administrative Code.
Installations, both existing and new, and parts thereof shall be maintained in proper operating condition in accordance with the original design and in a safe and sanitary condition. Devices or safeguards that are required by this code shall be maintained in compliance with the applicable provisions under which they were installed.
The owner or the owner's designated agent shall be responsible for maintenance of plumbing systems. To determine compliance with this provision, the commissioner shall have the authority to require any plumbing system to be inspected.
Additions, alterations, renovations or repairs to installations shall conform to that required for new installations without requiring the existing installation to comply with all of the requirements of this code. Additions, alterations or repairs shall not cause an existing installation to become unsafe, hazardous or overloaded.
Minor additions, alterations, renovations and repairs to existing installations shall meet the provisions for new construction, unless such work is done in the same manner and arrangement as was in the existing system, is not hazardous and is approved.
In addition to the requirements of Sections 102.4 and 102.4.1, the provisions of Sections 102.4.1.1 through 102.4.1.3 shall apply to prior code buildings.
For prior code buildings, the number of required plumbing fixtures shall be permitted to be calculated based on the 1968 Building Code utilizing the occupant load figures from the 1968 Building Code, or shall be permitted to be calculated based on the New York City Plumbing Code utilizing the occupant load figures from the New York City Plumbing Code.
For prior code buildings, the determination as to whether seismic requirements apply to an alteration shall be made in accordance with the 1968 Building Code and interpretations by the department relating to such determinations. Any applicable seismic loads and requirements shall be permitted to be determined in accordance with Chapter 16 of the New York City Building Code or the 1968 Building Code and Reference Standard RS 9-6 of such code.
For prior code buildings, equipment, appliances and supports that are exposed to wind shall be designed and installed to resist the wind pressures determined in accordance with Chapter 16 of the New York City Building Code.
The standards referenced in this code shall be those that are listed in Chapter 13 and such standards shall be considered as part of the requirements of this code to the prescribed extent of each such reference. Where differences occur between the provisions of this code and the referenced standards, the provisions of this code shall be the minimum requirements. Refer to Article 103 of Chapter 1 of Title 28 of the Administrative Code for additional provisions relating to referenced standards.
References to standards in this code shall be to the editions of those standards provided for in Chapter 13 of this code, or as otherwise provided by rule.
Requirements necessary for the strength, stability or proper operation of an existing or proposed plumbing system, or for the public safety, health and general welfare, not specifically covered by this code, shall be determined by the commissioner.
Reference to chapter or section numbers, or to provisions not specifically identified by number, shall be construed to refer to such chapter, section or provision of this code.
Refer to the New York City Charter and Chapter 1 of Title 28 of the Administrative Code.
The commissioner shall have the authority to render interpretations of this code and to adopt rules, policies, and procedures in order to clarify and implement its provisions . Such interpretations, policies, procedures, and rules shall be in compliance with the intent and purpose of this code. See the New York City Charter and Chapter 1 of Title 28 of the Administrative Code for additional provisions relating to the authority of the Commissioner of Buildings.
If the commissioner determines that a system of storm water disposal which has been previously approved under the provisions of this code or of previous codes is no longer providing adequate drainage of storm water from a lot or development, the commissioner shall order repair of such system as required by Section 28-301.1 of the Administrative Code; or if, in the judgment of the commissioner, repair of such system is not sufficient to ensure adequate drainage of storm water from such lot or development, the commissioner shall order that one of the methods of storm water disposal set forth in Chapter 11 shall be used to provide such drainage. The commissioner may apply to the Board of Standards and Appeals for modification of the Certificate of Occupancy of any building constructed on such lot or development to require the use of such method.
