Municipal codes
Local ordinances may affect some construction projects. Examples of these are fences, sewer hookups, swimming pools, etc. Current editions of local ordinances are available in municipal offices. Some are also online. Contact your local Construction Official or Building Inspector if you have questions about permits and code.

Legislative history
To end the hodgepodge of local construction regulations and codes, the state of New Jersey passed the New Jersey Uniform Construction Code Act on October 7, 1975. The Act became effective on February 3, 1976. All construction codes and their enforcement were now to be controlled by the provisions stated in the act. The New Jersey Uniform Construction Code is comprised of subcodes (model codes and standards) that are adopted individually by the Commissioner of Community Affairs and which are often supplemented or extensively amended by the Uniform Construction Code Regulations (New Jersey Administrative Code [N.J.A.C.] 5:23-1 et seq.) which went into effect on January 1, 1977. The subcodes are the basic "nuts & bolts" manuals on how construction is to be done and are usually published by national technical organizations, e.g. BOCA. Those formulated by the State, such as the Rehabilitation Subcode, often cite other standards (ANSI, NFPA) and even federal regulations, e.g. for manufactured homes, to address specific situations. Patrons must consult N.J.A.C. 5:23-1 et seq. to identify not only the subcode/standard that applies but also the additions, deletions, or exceptions that the State has made to those subcodes/standards.

The N.J.A.C. regulations may change at any time. Newer model subcodes are periodically adopted but the process has become very irregular. The most recently published model code may not yet have been adopted by the State.

Only a large technical library can afford to purchase all the codes and standards cited in the regulations. MCL has retained older codes cited in the DCA list, which can be invaluable information for people with homes built/remodeled in the past.
