2025 New York State Plumbing Code

The 2025 Plumbing Code of New York State sets minimum standards for the design, installation, and inspection of plumbing systems statewide. Based on the 2024 IPC with NY-specific amendments, it governs commercial and multi-family systems including water supply, drainage, vents, storm systems, and medical gas piping. Residential plumbing for smaller dwellings is covered under the Residential Code, and fuel gas piping is addressed separately. Organized by system components, it includes requirements for fixtures, water distribution, sanitary drainage, and system safety, including flood protection measures. Essential for builders, engineers, and inspectors to ensure safe, compliant, and efficient plumbing design and installation.
