The City of Chicago requires permits for a number of projects. This ensures that the projects adhere to city codes and minimum standards and promotes the safety of your building.
You can find a list of projects that require permits on the City of Chicago's Dept. of Buildings website. You can also find information on the Easy Permit Application process, which can be completed online to obtain a permit for certain projects.
Before you begin any repair, replacement or construction project and when interviewing contractors, be sure that you (or your contractors) obtain the proper permits required by the city!
