What is a warehouse mezzanine?

A mezzanine is an elevated intermediate floor inside a building that adds usable space for storage, picking, or offices without expanding the building footprint.

Do I need a permit for a mezzanine?

Yes in most California jurisdictions. Mezzanines and work platforms are engineered structures that typically require stamped drawings, permits, and inspection like any building modification.

Storage vs work-platform mezzanine?

Storage mezzanines emphasize rack or bulk storage above; work platforms emphasize people, packing, or light equipment. Design, loads, and egress requirements differ — the engineered plan sets the right type.

Mezzanines & Work Platforms

Build up instead of out. A mezzanine or work platform reclaims vertical space for storage, picking, or offices without moving buildings. Engineered and permitted like any structure, and often the most cost-effective square footage you will ever add. Best when you are out of floor but have height to spare.
