One and Two Family Residential Permit Review Process

The applicant starts and finishes the permit process at the same location. One & Two Family Residential permits are processed simultaneously by three City departments to make the process more efficient. When permit applications are submitted to the Building Safety Division at the Champaign Fire Department, they are routed to the individual reviewers that need to review the particular application. The applicant will be contacted by the individual reviewers with questions and comments.  The review process is constantly tracked by permitting software which can be monitored by the applicant online.  All departments welcome the chance to review particular portions of applications prior to their formal submission in order to make the permitting process proceed smoothly.
