The 2020 Residential Code of New York State (RCNYS) sets the minimum requirements for one- and two-family dwellings and townhouses, promoting the use of new materials and innovative building designs. This edition, rooted in the 2018 International Residential Code, covers the construction of single-family houses, duplexes, and townhouse units limited to three stories above grade. The code is specifically tailored to residential construction, allowing users to easily navigate applicable provisions without the clutter of irrelevant regulations.
The RCNYS includes detailed guidelines for all aspects of a house or townhouse, including structural components, fireplaces, chimneys, thermal insulation, mechanical systems, fuel gas systems, plumbing, and electrical systems. It utilizes a prescriptive approach with elements of performance-based language, serving as a comprehensive guide for standard residential construction while referencing other codes for more unique or uncommon building practices.
Structured to follow the natural progression of construction from design to final trim-out, the RCNYS is divided into eight main parts, addressing everything from administration to specific construction standards for various building systems. Each chapter focuses on different aspects of building planning and construction, like foundations, wall and roof construction, and special appliances, ensuring each component meets safety and efficiency standards.
Furthermore, the code includes chapters on advanced topics like solar energy systems and radon control, demonstrating its comprehensive approach to modern residential building requirements. This thorough coverage makes the RCNYS an essential resource for ensuring safe, efficient, and up-to-date residential construction practices in New York State.
