Do I Need Engineering for a Commercial Remodel?

Quick Answer

Commercial remodels almost always require engineering. Most commercial building permits require stamped structural drawings for any work affecting the structure, and stamped MEP plans for any mechanical, electrical, or plumbing changes. Even light commercial tenant improvements typically require MEP engineering to verify compliance with current codes.
