This page is a link to the Department of Community Affairs in Trenton. The DCA, should not to be confused with the other DCA, The Dept. of Consumer Affairs in Newark. The Dept. of Consumer Affairs in Newark oversees the needs of consumers and the licensing of professionals and businesses. The DCA in Trenton oversees communities, inspectors, building and code enforcement rules and regulations and much, much more. They ARE the law.
Their website has a lot of very useful information in regards to construction and renovation codes and standards. The site has an enormous amount of information so I will limit my links to the ones that I think will be most useful to us as home, property and business owners.
