Plumbing Codes
Please note that the library cannot help determine which codes apply to your specific project.
The codes adopted by law are published by the International Association of Plumbing and Mechanical Officials (IAPMO), the International Code Council, and the National Fire Protection Association (NFPA).
The publishers of the codes make some editions available for free online — often with some restrictions — but note that it may not always be possible to find an online version of the code as it existed on the date specified by law. In order to view NFPA publications, you must first set up a profile and agree to their licensing restrictions. To view IAPMO documents, you may need to install Adobe Flash Player.
