Permits in Calabasas
Calabasas is its own incorporated city, so plans go to the City of Calabasas's building department — not to Los Angeles LADBS. Its own zoning code, setbacks and plan-check queue apply, and they differ from the City of LA's. We file the drawings, answer plan-check corrections and book the inspections.
