Zoning Report
Irvine, CA Zoning
Irvine uses a large, highly customized zoning ordinance that combines citywide rules with planning-area-specific standards. The code includes overlay districts that add extra requirements for sensitive areas such as floodplain and hillside locations, and many major development rules are tied to specific planning areas rather than a simple citywide Euclidean district map. Recent ordinance activity shows the city is actively updating residential, mixed-use, setback, parking, and planning-area standards.
