Rodents in a Condominium: Who Acts, Who Pays?

Common areas or private lots: the distinction that changes everything

The first question to ask when rats or mice show up in a condominium is where the problem actually sits. Basements, bin rooms, shared pipework, underground car parks or communal green spaces are common areas. An individual flat is a private lot. This distinction directly determines who organises treatment and who pays for it.

Who organises treatment in common areas

When an infestation affects common areas, it's the property manager's job to organise treatment, acting as the representative of the owners' association. For routine maintenance or a health emergency, the property manager can generally act directly under the powers granted by the condominium rules, without waiting for the next general meeting. An individual owner has no authority, in principle, to have common areas treated on their own initiative — reporting the issue to the property manager remains the first step.

How the cost of rodent control is split

Treatment of common areas is funded through condominium service charges, split between owners according to their share as defined in the condominium rules — not by the single occupant who first reported the problem. For a private lot, however, treatment remains at the expense of its occupant (owner or tenant, depending on the lease), unless the infestation is clearly linked to a structural issue in the common areas.

What if the infestation also reaches private flats?

Rodents don't respect cadastral boundaries: a colony established in a basement or shared service ducts can reach several flats. In that case, treating only the affected flats without tackling the source in the common areas only delays the return of the infestation. A coordinated, building-wide diagnosis with the property manager helps identify the real source and avoid an ineffective, partial treatment.

The property manager's role when a report comes in

A written report (email or letter), describing the affected areas precisely and ideally accompanied by photos, allows the property manager to act faster and leaves a useful record in case of later disagreement. When several owners report the same issue, the decision is generally made faster than with an isolated report. For buildings that face this kind of issue regularly, a preventive maintenance contract avoids having to react in an emergency each time — see our offer for property managers and condominiums.

How much does condominium rodent control cost

The price depends on the extent of the common areas to be treated (number of basements, technical rooms, length of pipework) and is quoted after an on-site diagnosis. As a reference point, our rodent treatment for an individual lot up to 50 m² starts at €300 including tax, both passes included — see our pricing page or request a quote tailored to your building.
