Single Family Homes/New Construction Information

A permit is legal authority to begin a project and triggers an inspection process. Inspections need to be performed at various stages of a project to ensure compliance with the approved plans and construction codes. Although each project is unique, certain types of work and stages of construction need to be inspected and approved before proceeding. Please refer to the individual project guides for specific inspection requirements and if you have questions regarding your project, please contact the Building Department.

Scheduling Inspections – Inspections are taken on a first serve basis and 24 hour advance scheduling is required. Due to workloads and scheduling, some inspections will not always be conducted the next day but will be done within 48 hours. As a general rule, inspection times are available for pre-pour concrete and sewer & water inspections. Typically all inspections will be completed between 8:30 and 3:30 of the following day. Prior to scheduling an inspection, please make sure the work for which you are requesting an inspection is complete and ready for inspection. A fee of $50 is charged for any failed inspection which includes projects that are not ready when the inspector arrives. Please call the Building Department at (815) 462-6490 to schedule an inspection.

Due to our weather conditions, especially during the winter, the Building Department acknowledges that there will be times when exterior work cannot be conducted. From the dates of December 1st and March 30th the Village prohibits concrete flatwork form being placed on property and also regulates timing and insulation requirements for footings and foundations. This is done to ensure that freezing conditions do not adversely affect fresh concrete. During this time period, bonds are accepted in lieu of installing the exterior concrete. Please review the building guide or contact the Building Department for more information on cold weather conditions.
