Do I need a permit for screen enclosure or pool cage in Highland Park?
Yes. In Illinois, screen enclosure or pool cage generally requires a permit, and Highland Park is no exception.
Highland Park treats porches, decks, and similar attached structures as work that needs a building permit, and the City has requirement sheets for Wood Deck and for Porch, Arbor, Pergola. A screened porch or covered enclosure is handled as new attached construction. Confirm the correct submittal sheet with the Highland Park Building Division. The structure must meet Chapter 150 zoning setback and lot-coverage rules, verified against your plat of survey. Enclosing an existing deck or porch can change how the space is classified under the 2024 building codes. For lots with a ravine, bluff, or regulated drainage feature, added footings or grading may trigger stormwater or Lake County Watershed review, so check before ordering materials. 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.
