The fonds de travaux: what a Luxembourg building's reserve tells a buyer

Since August 2023 every Luxembourg co-ownership has been required to hold one, funded by a compulsory annual contribution with a legal floor. Read properly, it is the closest thing a buyer has to a financial health check on the building.

What the law now requires

The obligation comes from the law of 30 June 2022 and applies from 1 August 2023. Owners must constitute a fonds de travaux to meet the cost of works decided by the general assembly, funded by a compulsory annual contribution paid in proportion to each owner's millièmes.

The purpose is explicitly forward-looking: to build the cash needed to anticipate maintenance and renovation, to smooth exceptional expenditure over time, and to make it easier to finance renewable energy installations in the common parts. It covers maintenance, repair, improvement, transformation and renovation of the building, infrastructure in the common parts, and renewable energy production and storage installations there.

The amount is voted by the general assembly, but it cannot fall below a floor fixed by grand-ducal regulation. That floor is expressed per square metre of energy reference surface as shown on the energy performance certificate, graded by the building's thermal insulation class. Where no valid certificate exists, the surface attached to the lots under the acte de base applies. The Ministry of Housing has estimated a contribution in the region of €30 to €40 a month for an 80 m² apartment in a building that performs poorly.

Two funds that are frequently confused

The fonds de roulement is working capital. It exists so the syndic can pay the building's invoices at the start of an accounting year, including insurance, the lift contract, waste management and the first energy advance, which fall due before the owners' first monthly payments have accumulated. It is usually provided for in the règlement de copropriété.

The fonds de travaux is different in kind. It is accumulated for works voted at the assembly, and a pre-existing reserve fund may be integrated into it provided the legal minimum is respected. Opening a dedicated bank account for it is an option rather than an obligation, and the syndic is responsible for calling the contributions, recovering them, accounting for them and calculating the balance acquired by each lot.

When you ask a seller or a syndic "how much is in the fund", specify which fund. The answers are not interchangeable.

What the balance actually tells you

Read the fund against the building's age and its known liabilities rather than in isolation. A facade renovation typically arises every fifteen to twenty years, a roof and a lift on their own cycles, and energy upgrading is now a foreseeable obligation rather than an option.

Three readings are worth distinguishing. A well-provisioned fund in an older building indicates an assembly that has been planning, and it is the most reassuring signal available to a buyer. A thin fund in a new building is normal and not alarming, since the liabilities are distant. A thin fund in an older building with visible deferred maintenance is the combination to price into your offer, because the works will happen and the call will be proportional to your millièmes.

Ask a fourth question that the balance does not answer: whether any works have been voted and not yet called for, which is a liability that already exists.

What transfers to you at the deed

Because the syndic calculates the balance acquired by each lot, the position on transfer is a matter to settle explicitly rather than assume. Ask your notary how the fund balance attaching to the lot is treated between seller and buyer in your transaction, and ask the syndic for a written statement of the lot's position, including any arrears.

Arrears are the item to check hardest. A co-ownership where several owners are in default is a co-ownership whose voted works are difficult to fund, and the syndic is obliged to pursue recovery on its own initiative under the 1975 law without needing the assembly's authorisation.

The governance around the money

Three organs matter. The syndic is the executive agent, and a professional syndic is required beyond a certain number of lots. The general assembly is sovereign and votes the budget, the works and the syndic's position. The conseil syndical is an optional elected body of owners that supervises management.

The majorities are worth knowing before you buy, because they determine how easily anything happens. Approval of the accounts, the annual budget and maintenance or repair works are taken on a simple majority of those present or represented. Appointing or removing the syndic, authorising private installations such as an awning or a satellite dish, and improvement works require an absolute majority of all millièmes, whether present or not.

That distinction explains a great deal about buildings where nothing gets done. In a co-ownership with absentee owners, an absolute majority of all millièmes is difficult to assemble, and the works that require it are exactly the ones that improve the building.

Three questions we are asked

Can the assembly vote a contribution above the legal floor? Yes, and a building that does so is usually one taking its liabilities seriously. The floor is a minimum, not a target.

Is the fund refundable if I sell? The fund is accumulated for the building's works and the syndic calculates each lot's acquired balance. How that is treated on a sale is a matter for your deed and your notary, so raise it before signing rather than afterwards.

What if the seller cannot produce the assembly minutes? Ask the syndic directly, through the notary if necessary. A purchase completed without having read three years of minutes is a purchase made without knowing what has already been decided.

Questions to put to the syndic in writing

Ask through the seller or the notary, and ask for written answers. Six lines that a well-run syndic can respond to in a single email.

• What is the current balance of the fonds de travaux, and what is the annual contribution per lot for this apartment?
• What is the building's thermal insulation class on the energy performance certificate, and what energy reference surface is used to calculate the minimum contribution?
• Have any works been voted and not yet called for?
• What are the total arrears across the co-ownership, and is any recovery action in progress?
• When were the roof, the facade, the lift and the heating plant last renewed?
• Is any technical study or energy audit currently under way?

The answers give you a liability picture that no viewing can produce. The speed and precision of the reply gives you a second, less formal reading: a syndic that answers in two days manages a building differently from one that takes three weeks, and you will be dealing with them for as long as you own the lot.

How the fund changes what a building can actually do

A well-funded co-ownership does not merely pay for works; it can decide them. The link is the majority rules.

Approval of the accounts, the annual budget and ordinary maintenance or repair works are taken on a simple majority of owners present or represented, which is usually achievable. Appointing or removing the syndic, authorising private installations, and improvement works require an absolute majority of all millièmes, present or not. In a building with absentee owners, that second threshold is difficult to reach.

Money and majorities interact. Where a fund already holds the cash, an improvement proposal is a vote about the building. Where it does not, the same proposal is a vote about writing a cheque, and it fails more often. That is why the balance of the fund is a better predictor of a building's trajectory over ten years than its current appearance.

For a buyer weighing two similar apartments, this is the tiebreaker worth using.
