WHO IS RESPONSIBLE – THE OWNER OR THE ASSOCIATION?
Water leaks in apartment buildings are among the most common and costly property issues. When damage occurs, the key question is often: who is responsible for the damage and repair costs?
Dividing responsibility between the owner and the building association
Although each apartment is privately owned, the building itself is a shared structure. Responsibility is generally divided as follows:
Apartment owner responsibility:
-
interior finishes
-
plumbing and wiring within the apartment
-
sanitary equipment and appliances
-
non-load-bearing walls
Building association responsibility (common property):
-
roof and façade
-
load-bearing structures
-
stairwells and corridors
-
shared plumbing systems and risers
-
electrical and ventilation systems
If a leak originates from within the apartment, the owner is typically responsible. If the source is part of the shared infrastructure, the responsibility falls on the building association.
What if the building association is not insured?
Not all associations have adequate insurance coverage. In such cases, damage to common property must often be covered from the maintenance fund, which may be insufficient in the event of major water damage.
Plumbing failures can affect multiple apartments at once, resulting in repair costs running into thousands of euros.
When water damage spreads between private and common areas
Leaks often spread beyond their original source.
-
Leaks originating inside an apartment → owner responsibility
-
Leaks originating from shared systems → association responsibility
-
Insurance may cover repairs but later reclaim costs from the party at fault
This is why both apartment owners and associations should have appropriate insurance coverage.
Most common causes of water damage
The most frequent water-related incidents include:
-
leaking or burst pipes
-
rainwater entering through roofs or ventilation shafts
-
aging sealants and waterproofing materials
-
poorly maintained plumbing systems
Many of these issues develop slowly and remain unnoticed until serious damage occurs.
Most water leaks can be prevented
Preventive maintenance, regular inspections, and early leak detection significantly reduce the risk of major damage.
