To protect the health and safety of the public and our employees, DCP has limited on-site staffing at 450 Columbus Blvd. While mail and phone calls will be processed as quickly as possible, we recommend using our online services, or sending an email to the appropriate division/person instead. We apologize for any inconvenience.

Home Improvement Contractor

Due to current events, it is highly recommended that all applications and renewals be submitted online.  Our ability to receive and process mailed applications, renewal notices and payments will be significantly delayed.

Pursuant to Public Act 21-37, the expiration date for home improvement contractor registrations has changed from November 30th to March 31st.  Please be advised the department has started to transition the expiration date for all new applications.  All active registrations expiring November 30, 2021 will be transitioned to March 31st at the time of renewal.
