Can I Convert a Warehouse to Office Space?
Often yes — warehouse-to-office conversions are the adaptive-reuse staple: the open floor plates, the high ceilings, and the industrial character suit the creative office. The engineering challenges: the change of occupancy (the code's requirements — the IBC Chapter 34/IEBC), the MEP (the warehouse's minimal systems vs. the office's demands), and the envelope (the metal building's thermal performance). The feasibility study precedes the lease.

Change of occupancy
The IEBC (the existing-building code — the work-area method; the change from the storage (S) to the business (B) occupancy triggering the requirements), the fire protection (the sprinklers — the office's requirements; the alarms; the egress — the occupant load's increase sizing the exits), the accessibility (the 20% disproportionality — the ADA's alterations rule; the entrance, the restrooms, the path of travel), and the structural (the office loads vs. the storage loads — typically lighter; the mezzanines — the new structure's design).
MEP transformation
HVAC (the warehouse's unit heaters vs. the office's comfort — the rooftop units or the VRF; the ventilation — the office's outside-air requirements; the distribution — the exposed duct aesthetic), the lighting (the office's illumination — the skylights plus the electric; the daylighting opportunity), the electrical (the office's power density — the distribution; the data — the connectivity), and the plumbing (the restroom count — the office's fixture requirements; the break rooms).
Envelope and cost
The metal-building envelope (the insulation retrofit — the liner system or the exterior insulation; the air sealing — the big-box leakage; the windows — the new openings' structural headers), and the character (the exposed structure — the aesthetic asset; the polished concrete — the flooring). Cost: $100-$250+/sq ft for the quality conversion (the MEP dominating). The feasibility study ($10,000-$30,000) — the code analysis, the MEP assessment, the budget — before the commitment.
The bottom line
Warehouse-to-office conversions navigate IEBC change-of-occupancy (fire, egress, accessibility), the full MEP transformation, and the envelope retrofit — budget $100-$250+/sq ft; study feasibility first.
