Short answer:<\/strong> in the event of water damage caused by the upstairs neighbor, your Property Manager may not enter without permission. However, they can formally serve the upstairs neighbor a notice of default, involve the insurer and, if necessary, ask the Justice of the Peace to order access. Who pays for the repair depends on where the leak is located: in a common area or a private part.<\/p>\n\n

A damp spot appears on your ceiling: water damage that almost certainly comes from the upstairs neighbor. A week later, it also appears at the neighbors' one floor down. But that upstairs neighbor refuses to let a technician in. Frustrating, because in the meantime, the water continues to flow.<\/p>\n\n

In such a situation, many owners immediately look to the Property Manager<\/a>. Rightly so, because the Property Manager has an important role in water damage within an apartment building. But that role also has limits. In this article, you will read what a Property Manager must do, what they can do, and where their authority ends.<\/p>\n\n

Where is the leak: common area or private part<\/h3>\n\n

Everything depends on one question: is the cause of the water damage located in a common area or in a private part of the building?<\/p>\n\n

<\/th>Common area<\/th>Private part<\/th><\/tr><\/thead>
Examples<\/strong><\/td>Vertical drainage column, main water pipe, leak in the roof or facade<\/td>Leaking tap, loose siphon, worn silicone around the shower, defective washing machine<\/td><\/tr>
Responsible<\/strong><\/td>The Owners Association (Owners Association<\/a>)<\/td>The owner of the apartment (and possibly the tenant)<\/td><\/tr>
Repair<\/strong><\/td>The Property Manager has the repair carried out<\/td>The owner carries out the repair themselves<\/td><\/tr><\/tbody><\/table><\/figure>\n\n

What is common and what is private is stated in the articles of association<\/a> of your building. That deed is therefore the first document your Property Manager will consult.<\/p>\n\n

The problem: as long as the upstairs neighbor keeps the door closed, you often do not know where the leak is. That is where the work of the Property Manager begins.<\/p>\n\n

What the Property Manager does in case of water damage caused by the upstairs neighbor<\/h3>\n\n

The law tasks the Property Manager with managing the building and taking conservatory measures when the common areas are at risk [art. 3.89 \u00a75 of the Civil Code]. A leak that affects ceilings, walls, and pipes often falls under this. In practice, the approach looks like this.<\/p>\n\n

1. Identifying and documenting damage<\/h4>\n\n

The Property Manager collects photos, reports from the affected owners, and possibly an initial assessment by a technician from the damaged apartments. The better the file, the stronger each subsequent step.<\/p>\n\n

2. Engaging with the upstairs neighbor<\/h4>\n\n

Often there is no ill will, but rather fear, shame, or simply distrust. A phone call or a letter explaining what is happening and what is expected of the upstairs neighbor resolves a lot.<\/p>\n\n

3. Involving the insurer<\/h4>\n\n

The insurer can send an expert, and that expert also needs access. A refusal can jeopardize coverage, which is often an additional argument for the upstairs neighbor to cooperate after all.<\/p>\n\n

4. Formally serving the upstairs neighbor a notice of default<\/h4>\n\n

If the door remains closed, the Property Manager sends a registered letter with a clear deadline. An owner is legally obliged to provide access to their private unit when necessary for works on common areas. The letter points this out, as well as the owner's liability for the damage that continues to occur.<\/p>\n\n

5. Taking urgent measures in the common areas<\/h4>\n\n

If the Property Manager can temporarily shut off the water via a common tap or limit the damage elsewhere, they are permitted to do so. They take into account the inconvenience to other residents and communicate clearly about it.<\/p>\n\n

6. Going to the Justice of the Peace<\/h4>\n\n

If nothing works, the Property Manager can, on behalf of the Owners Association, ask the Justice of the Peace to order access, if necessary under penalty of a fine. In cases of extreme urgency, this happens quickly. For such an urgent or conservatory procedure, a prior decision by the general assembly<\/a> is usually not required. The costs can afterwards be recovered from the owner who refused access.<\/p>\n\n

If the leak is indeed in a private part, the role of the Property Manager shifts. They serve the upstairs neighbor a notice of default, monitor the common areas, and keep the other owners informed. The repair itself is then the responsibility of the upstairs neighbor.<\/p>\n\n

Is the Property Manager allowed to enter the upstairs neighbor's unit<\/h3>\n\n

No. A Property Manager does not have a key to every apartment, and that is for the best. A private unit remains a home. Therefore, they may not:<\/p>\n\n

    \n
  1. Play judge between neighbors.<\/strong> Who must compensate which damage is decided by the insurers, the owners involved, or ultimately the judge. The Property Manager coordinates but does not judge.<\/li>\n\n\n\n
  2. Enter without permission.<\/strong> Not even with a technician, not even if it is urgent. Without the resident's agreement or a court decision, the door remains closed.<\/li>\n\n\n\n
  3. Call a locksmith.<\/strong> Forcing the door is not an option, no matter how great the damage is.<\/li>\n\n\n\n
  4. Carry out private repairs on their own initiative.<\/strong> A leaking shower or tap in the upstairs neighbor's apartment is not the responsibility of the Owners Association. The Property Manager may not have it repaired at the expense of all owners.<\/li>\n<\/ol>\n\n
