Do I need a permit for screen enclosure or pool cage in Joliet?
Yes. In Illinois, screen enclosure or pool cage generally requires a permit, and Joliet is no exception.
Joliet treats gazebos, pergolas, roofed structures, and covered patios as permitted construction, so a screen enclosure or covered porch is filed on the Gazebo/Pergola/Roofed Structure application with an accurate plat of survey. When a covered structure attaches to the house, the roof must meet the same setback requirements as the house, and all closed-roof structures together may cover no more than 30 percent of the lot. Processing is estimated at about 15 business days, and if a contractor performs the work the contractor must pull the permit (Sec. 8-36 of the Code of Ordinances). Most Illinois jurisdictions treat a screen room or enclosed porch as a structure requiring a permit and setback or zoning review. Many local codes require footings designed for the local frost depth. The frost depth and the structural requirements come from the code edition your jurisdiction has adopted rather than from a statewide Illinois residential code.
