Cat A vs. Cat B: Office Fit-Out Classification and Responsibility Checklist
We first put the responsibility, scope, price and time into the same enterprise project framework to help your company clarify the budget, approval and delivery boundaries before launching the project.

Actual boundary between Cat A and Cat B
Hong Kong office buildings often regard basic ceilings, floors, air conditioning trunks, fire protection systems and public facilities as basic delivery, but the standards of different buildings are not completely consistent. Tenants typically move into Cat B scope when furnishing conference rooms, front desks, individual offices, access control, networking, furniture and branded walls.
Responsibility matrices are more reliable than definitions
In the same project, fire sprinkler relocation may be paid by the tenant, constructed by a designated contractor, submitted by the fire contractor, and approved by the management office. Corresponding each node to your company, design, contracting, professionals, BMO and designated contractors can truly control risks.
Restoration obligations should be reviewed in advance
The glass house, elevated platform, access control, lighting and air conditioning changes added today may all be restored when the lease expires. Establishing a restoration strategy during the renovation stage can reduce deposit disputes when renting out in the future.
Checklist before project start
| material | Confirm key points |
|---|---|
| ceiling/floor | Confirm the original status, scope of changes and whether restoration is needed in the future |
| Fire/air conditioning | Confirm designated contractor, submittal documentation and testing responsibilities |
| Access control/IT | Confirm weak current points, cabinets, power supplies and handover drawings |
Once your company submits floor plans, leases or fit-out manuals, it gets a management-readable list of risks, budget gaps and information.
