Mezzanine and Platform Permit Drawings
Structural design for mezzanines, raised platforms and equipment decks inside existing buildings. Adding a floor inside a building changes loads, exits and sometimes the occupancy itself.
structural set, starting fee. Final pricing is confirmed in writing before work begins.
Drawings your jurisdiction will ask for
- ✓ Framing plan with beam, column and deck design for the intended load
- ✓ Column base and existing slab verification, including new footings where needed
- ✓ Connection details to the existing structure where the mezzanine ties in
- ✓ Stair, guard and handrail design meeting code geometry and loads
- ✓ Egress analysis, including a second exit where area or occupancy requires it
- ✓ Lateral bracing so the mezzanine does not rely on the building for stability
Frequently asked questions about Mezzanine Permit Drawings
Do I need a permit for a mezzanine?
Yes in almost every case, even for a prefabricated system. The jurisdiction wants stamped structural design plus egress and guard details, because it is effectively a new floor level.
Can the mezzanine sit on the existing slab?
Sometimes, but not usually without checking. Column loads are concentrated and typical slabs are not designed for them. We verify and add footings where required rather than assuming.
Does a prefab mezzanine kit still need engineering?
Usually yes. The supplier designs the kit, but the jurisdiction still wants a licensed engineer to confirm the foundation, anchorage and how it works with your specific building.
