Do mezzanines require permits and engineer-stamped drawings?
Quick Answer
Yes. Because a mezzanine changes a building’s structural load and egress, most local building departments treat it like any other floor addition. They typically require a building permit supported by engineer-stamped drawings that verify live loads, seismic factors, anchorage and guardrails. Warehouse Cubed supplies the sealed plans and manages permitting for you.

Detailed Answer
Under the International Building Code (IBC) and most municipal ordinances, a warehouse mezzanine is classed as a structural platform, not temporary shelving. That means you must pull a building permit and submit engineer-stamped drawings that prove the platform’s column spacing, live-load capacity, stair and handrail design, sprinkler clearances, and means of egress all meet code. Skipping this step can halt your project, trigger fines, or void insurance.
Warehouse Cubed’s warehouse consulting services remove that headache. During the layout phase we create detailed CAD models, run load calculations, and have a licensed professional engineer stamp the drawings. Our permitting specialists then file the application, answer plan-review questions, and coordinate any site inspections, freeing you to focus on operations.
Because the mezzanine integrates with pallet racking, conveyor systems, or automated storage and retrieval systems (AS/RS), our material handling systems integration team ensures every component, from gate openings to VRC lifts. remains compliant after installation. Coupled with optional warehouse safety audits, this turnkey approach delivers a code-approved, future-ready platform that maximizes vertical space, supports warehouse optimization, and keeps your team safe without costly construction delays.
