Warehouse Review Items to Plan Early
Warehouse projects can involve large open spaces, mixed uses and building systems that must be understood before a permit package is submitted.
| Review Item | Why It Matters | What to Show in the Drawings |
|---|---|---|
| Existing and proposed use | Industrial, storage, office and showroom areas may have different occupancy and zoning implications. | Existing/proposed use notes, area breakdown, room names and change-of-use coordination where required. |
| Exits and travel distance | Large open warehouse areas, storage layouts and new rooms can affect exit access and life safety. | Exit routes, door locations, travel distance assumptions, occupant load and life-safety notes. |
| Fire separations and demising | New office areas, service rooms or demising walls may need fire-resistance or life-safety review. | Wall types, rated assemblies where applicable, door notes and affected building-system coordination. |
| Washrooms and staff areas | New staff spaces or customer-facing areas can trigger washroom, plumbing and accessibility review. | Washroom fixture locations, accessible clearances, staff room layout and plumbing coordination. |
| Mechanical and industrial systems | Heating, ventilation, exhaust, loading, equipment or specialized processes may require consultant input. | Equipment locations, ventilation notes, affected ducts/services and consultant drawings when triggered. |
