Introduction to... Building Codes

Updated March 24, 2017.

To find building codes, you may need to check at the local, state, and federal levels. The state building code sets the minimum standards for the state, but local governments can have more stringent standards. Federal standards may also apply in some situations.

The "New Hampshire building code" (or "state building code" or “building code of the state of New Hampshire”) is really several codes as amended by the State of New Hampshire. They are: the International Building Code 2009, the International Plumbing Code 2009, the International Mechanical Code 2009, the International Energy Conservation Code 2009, the International Residential Code 2009, the International Existing Building Code 2009, and the National Electrical Code 2014. These model codes, published by the International Code Council and the National Fire Prevention Association, have been adopted by the State of New Hampshire (RSA 155-A) and are amended by administrative rule (Bcr 300). 

The "New Hampshire fire code" or "state fire code" refers to the Life Safety Code (2009 ed.) and the Uniform Fire Code NFPA 1 (2009 ed.) as amended by New Hampshire, as well as other national codes, model codes, or standards referred to within these codes. The Life Safety Code and the Uniform Fire Code are published by the National Fire Protection Association. They were adopted by the state of New Hampshire (RSA 153) and are amended by administrative rule (Saf-C 6000).  

There are many other codes: commercial building codes, historic structure codes, cultural resources codes, fuel gas codes, etc., that may have been adopted by a particular municipality so to be sure to check the town or city’s website. Start by looking for the code enforcement department or its equivalent. We’ve found it under various names: code enforcement, code administration, building department, or building inspection to name a few. Look for something along the lines of “current codes enforced.” For some towns, we had to look at the building permit application documents to figure out what codes those towns were enforcing. Check the ordinances as well, but be careful because many of those are out of date. You may see references to building codes, but some municipalities never updated their ordinances when the state building code was enacted in 2002. If the ordinances refer to building standards that are much older than the state’s current versions, keep looking.

Whether your municipality has building and fire inspectors on staff or not, there are state wide standards for both building and fire codes that every municipality and property owner must adhere to. The array of RSA’s and enabling rules which set the state codes, when they apply, what to do when they overlap, and how they can be appealed, can be confusing even for seasoned practitioners of the codes.   GO>
