Submit completed application with one (1) set of building and site plans. Any plans and information pertaining to the grading and drainage, erosion control or sump pump discharge should be separate and attached to those application forms.
Estimated Plan Review Time
Five (5) business days from receipt of all material. Plan review time is subject to application and plans being complete and in compliance with all codes and ordinances.
One and Two Family Permit Review Process
One & Two Family Dwelling permits are processed by three City departments. When a building permit application is submitted to Building Safety at the Champaign Fire Department, it is separated into its component parts and routed to whichever individual inspectors need to review a particular application. The plans and review process are constantly tracked by permitting software. The applicant starts and finishes the permit process at the same location. 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.
One Family Dwelling
- Less than 2,500 gross square feet = $345
- 2,500 or more gross square feet = $435
- Addition/Alteration = $6 per $1,000 of construction costs.
Two Family Dwelling
- Less than 2,500 gross square feet = $375
- 2,500 or more gross square feet = $470
