Co-ownership management in Luxembourg: the role of the syndic
In Luxembourg, the management of a co-owned building is governed by the law of 16 May 1975 on co-ownership of buildings. Professional syndics (such as BRUNATA, Leximmo, ImmoConcept) handle the administrative, technical and financial management on behalf of the co-owners' assembly.
Their responsibilities include: preparing the budget forecast, distributing charges according to shares, maintaining common areas, arranging insurance, and keeping accounts. The syndic convenes and chairs general assemblies and implements voted decisions.
Our digital dashboard enables syndics to efficiently simulate and present energy renovation scenarios, a central challenge given EPBD obligations.
Co-ownership charges distribution: rules and best practices
Common charges distribution in Luxembourg co-ownership follows precise rules:
- General charges (art. 6, law 1975): distributed according to co-ownership shares proportional to the relative value of each private lot.
- Special charges: certain charges may be distributed by utility (elevator by floor, heating by area).
- Reserve fund: building a reserve fund for major works is recommended (minimum 5% of annual budget).
- Transparency: the syndic must present detailed annual accounts and the forecast budget at the GA.
Energy renovation in co-ownership: obligations and subsidies
Energy renovation of co-owned buildings has become a major issue in Luxembourg:
- EPBD Directive 2024/1275: the worst-performing residential buildings must be renovated on a progressive timeline (class E by 2030, class D by 2033).
- Klimabonus / PRIMe House: Luxembourg's subsidy programme covers 30-50% of renovation costs for insulation, heating, windows and renewables.
- GA vote: energy renovation works require a qualified majority of 2/3 of shares (improvement works) or simple majority (necessary maintenance).
- Energy advice: myenergy offers free support for co-ownerships wishing to establish a renovation plan.
