Research notes
Dillon's-Rule enabling act for non-home-rule municipalities. Grants power to classify districts, regulate height, bulk, lot coverage, density, setbacks, parking, and land use. Codifies notice/hearing/ZBA procedural due process. Home-rule cities are NOT bound by procedural requirements unless expressly applied (Chicago operates entirely under MCC Title 17 grounded in home-rule).
