Construction Codes in Illinois
New legislation and administrative rules and regulations are passed by Illinois on a regular basis and therefore builders require keeping up with the various Illinois building codes and legal requirements that grow frequently. Engineering and construction professionals require knowing and understanding the significance of the law so that they can abide by the many requirements of building codes in Illinois.
It is important to follow the local building department. There is no centralized state mechanical code, plumbing code, and similar codes in Illinois, unlike many states. But local areas may have particular ordinances and building codes that should be adhered to when executing construction or maintenance on local buildings. It is essential to check with the city and the county to ensure that all the bases are covered.
Illinois state laws abound in terms of various requirements when constructing buildings anywhere in the state. The legislature as well as various administrative agencies can forward building laws, rules and regulations throughout the state.
These laws, rules and regulations are not passed by one government body. The state agency called the Illinois Capital Development Board Division of Building Codes and Regulations, passes the Illinois building codes. Though the Illinois Capital Development Board has administrative authority over the Illinois construction industry, the Division has an informational function. However, it adds each Illinois building code, law or administrative rule to a large compilation of Illinois building codes. The different Construction Codes followed in Illinois are mentioned below:
