How permitting works in Illinois

Cities in Illinois wield significant power through "Home Rule." The city's role is to create and manage its own permitting ecosystem, which often includes unique local requirements for fire suppression or historical preservation that go beyond any state-level recommendations.

Strong Home Rule; no mandatory state residential code.
