Basis under OC Act / Regulations
OC Act s.46 OC must maintain common property in good repair. Bin room is common property. Cockroach infestation in common areas is an OC maintenance obligation.
Recommended action
OC funds treatment from levies. Strata manager engages pest controller for common area treatment. Written report for OC meeting minutes.
Pest scenario
Rodents in basement carpark or plant room
Basement, loading bay, electrical room, pump room
Responsibility
OC responsibility
Basis under OC Act / Regulations
OC Act s.46 basement and service areas are common property. Rodent infestation originating in common areas is an OC obligation. Rodents gnawing building wiring are an OC safety matter.

Pest scenario
Cockroaches in lobby, lift, or common corridor
Building entry, lift car, common area hallways
Responsibility
OC responsibility
Basis under OC Act / Regulations
All common area corridors and lift cars are common property under the OC Act. Pest activity in these areas is an OC maintenance and amenity obligation.
Recommended action
OC funds treatment. Residual spray and gel bait to common area zones. If cockroaches are travelling from bin room, bin room must also be treated simultaneously.
Pest scenario
Cockroaches spreading from common area into individual apartment
Lot owner reports cockroaches; bin room or service duct is the source
Responsibility
OC responsibility
Basis under OC Act / Regulations
Where the pest source is common property, the OC is responsible for treating the source. Treatment of the individual lot affected may be funded by the OC if caused by common property pest pressure.
Recommended action
OC treats common property source first. Whole-building approach: all lot owners notified and access requested for simultaneous treatment to prevent re-infestation.
Pest scenario
Cockroaches originating inside an individual apartment
Isolated to one unit, no evidence in common areas
Responsibility
Lot owner responsibility
Basis under OC Act / Regulations
OC Act s.48 lot owners are responsible for maintenance within their own lots. A pest infestation isolated to a single lot and not originating in common property is the lot owner's responsibility.
Recommended action
Strata manager advises lot owner to engage a pest controller directly. OC may issue a notice if the infestation is spreading to adjacent lots.
Pest scenario
Cockroaches travelling between adjoining apartments through shared wall
Two or more adjacent lots with simultaneous activity
Responsibility
Shared whole-building recommended
Basis under OC Act / Regulations
Shared walls are common boundary elements. Where pests are travelling through shared walls between lots, coordinating whole-building treatment produces the most effective and legally defensible outcome.
Recommended action
OC coordinates whole-building treatment. Each lot owner provides access; OC funds common property treatment; lot owners fund treatment within their own lots.
Pest scenario
Possum in roof void of a strata building
Roof void is common property
Responsibility
OC responsibility
Basis under OC Act / Regulations
Roof void is common property. Possum removal requires a Wildlife Controller Licence and is a maintenance obligation of the OC. Entry point proofing is also OC funded.
Recommended action
OC funds licensed possum removal and roof entry point proofing. See our possum removal service.
Pest scenario
Wasp nest on building facade or common outdoor area
External building wall, common garden, rooftop
Responsibility
OC responsibility
Basis under OC Act / Regulations
External building fabric and common outdoor areas are common property. A wasp nest on common property presenting an injury risk to residents is an OC safety and maintenance obligation.
Recommended action
OC funds same day wasp nest removal. See our wasp removal service.
Pest scenario
End of lease pest treatment in a rented lot
Tenant vacating a lot within the strata building
Responsibility
Individual lot owner / tenant
Basis under OC Act / Regulations
End of lease pest treatment is governed by the Residential Tenancies Act 1997 (Vic) — a landlord-tenant matter within the lot, not an OC obligation. The OC is not involved.
Recommended action
Lot owner or tenant arranges directly. See our end of lease pest treatment service.
