Office Review Items to Plan Early
Office layouts can move quickly at the design stage, but municipal review still needs clear information about rooms, exits, accessibility and affected building systems.
| Review Item | Why It Matters | What to Show in the Drawings |
|---|---|---|
| New partitions and rooms | New rooms can affect egress, fire separations, ventilation, sprinklers, lighting and ceiling layout. | Existing/proposed plans, room names, dimensions, wall types, door swings and affected ceiling/services. |
| Exits and occupant load | More enclosed rooms or changed circulation can affect exit access and travel distance. | Occupant load notes, exit access routes, door widths, corridor widths and travel-distance assumptions. |
| Washrooms and accessibility | Office renovations may need accessibility review, especially when public/staff washrooms or path of travel are affected. | Accessible route notes, washroom dimensions, door clearances and fixture locations. |
| HVAC and ceiling coordination | Office partition changes can affect supply/return air, exhaust, lighting, sprinklers and fire alarm devices. | Reflected ceiling plan, diffuser/exhaust coordination, mechanical notes and consultant drawings where required. |
| High-rise office suites | High-rise offices can involve base-building standards, shared corridors, elevator lobbies, risers, fire alarm/sprinkler coordination and landlord review before city submission. | Suite/floor location, affected common areas, landlord standards, base-building drawings and consultant coordination notes. |
| Landlord/base building requirements | Commercial buildings often have submission standards beyond the city permit set. | Landlord drawing requirements, base-building drawings, demising notes and affected common/building services. |
