Commercial & institutional resilience
Plan flood resilience for condominium and rental apartment buildings using shared drainage, garages, resident needs, records and governance.
The practical answer
These properties combine commercial building systems with people’s homes. Shared garages, pumps, roofs, drainage, elevators and service rooms need professional management, while residents need clear information about access and responsibilities.
System view
Each area needs a defined purpose, owner, evidence trail and review cycle.

Guidance 1
These properties combine commercial building systems with people’s homes. Shared garages, pumps, roofs, drainage, elevators and service rooms need professional management, while residents need clear information about access and responsibilities.
For this topic, the organization should clarify common and unit responsibilities. The decision should be recorded with the responsible owner, evidence used, limitations, review date and any need for qualified technical, legal, insurance or municipal advice.
Commercial resilience depends on connected decisions. Building systems, site drainage, occupancy, maintenance, emergency response, continuity and capital planning should not be evaluated as isolated programmes.
Guidance 2
These properties combine commercial building systems with people’s homes. Shared garages, pumps, roofs, drainage, elevators and service rooms need professional management, while residents need clear information about access and responsibilities.
For this topic, the organization should map garages, pumps, roofs and utility rooms. The decision should be recorded with the responsible owner, evidence used, limitations, review date and any need for qualified technical, legal, insurance or municipal advice.
Commercial resilience depends on connected decisions. Building systems, site drainage, occupancy, maintenance, emergency response, continuity and capital planning should not be evaluated as isolated programmes.
Guidance 3
These properties combine commercial building systems with people’s homes. Shared garages, pumps, roofs, drainage, elevators and service rooms need professional management, while residents need clear information about access and responsibilities.
For this topic, the organization should keep resident storage away from controls. The decision should be recorded with the responsible owner, evidence used, limitations, review date and any need for qualified technical, legal, insurance or municipal advice.
Commercial resilience depends on connected decisions. Building systems, site drainage, occupancy, maintenance, emergency response, continuity and capital planning should not be evaluated as isolated programmes.
Implementation workflow
A useful commercial workflow identifies decisions, accountabilities and verification rather than producing an isolated report.
Assign an accountable owner, document the evidence and define what completion and verification will look like.
