Recently, a Houzy user sent an email to the Houzy magazine editors in response to our article "Proper Ventilation Improves the Climate and Prevents Mould". He is a condominium owner and believes that the other co-owners are heating unreasonably and that he is therefore paying too much for heating. His question as to whether he could do something about it prompted us to write this article about the fair distribution of costs in condominiums. The topic should interest even more condominium owners or people who are considering buying a condominium soon.

Talk to the neighbour before the situation escalates. Condominium associations are communities of convenience. You can read about how they work in our article "Condominium Ownership: That's Why Good Neighbours Are so Important".

Costs for own floor unit

In condominium ownership, all condominium owners bear the costs for their condominium unit themselves. The individual consumption must be measured and the heating, electricity and water costs must be charged according to consumption: Each person only pays for what he or she has consumed, regardless of the co-owners. This is fair and simple in newer buildings, because a meter measures the consumption for each floor unit. For condominiums in older buildings without meters, the consumption and thus the costs are distributed according to a fixed key, usually according to the value ratio. Then it can happen that someone pays comparatively more heating costs than the co-owners, even though he or she has heated less. As in the example of our user.

The importance of the value quota

The value quota is the costs distribution key for all common costs. For example, for the maintenance, repair or renovation of common parts or the operation of common facilities such as lifts or heating - and for the distribution of water, electricity and heating costs in a house without a meter. The value quota is defined in thousandths as soon as condominium ownership is established and entered in the land register. It depends on the size of the rooms in the special right and the ancillary rooms such as the cellar or laundry room, as well as the area of the parts with exclusive rights of use such as a car parking space or garden share. It can be weighted and refined by factors such as view, sunlight or floor height and is usually valid until the end of the condominium ownership.

Costs Distribution in Condominium Ownership: People Sit and Talk
If you want to change the value quota retrospectively, you must submit a motion to the condominium owners' meeting.

Change the value quota retrospectively

According to Article 712e of the Swiss Civil Code, a change in the value quota is possible if all parties directly involved agree and the condominium owners' meeting approves the change. The greatest chance is if the quota was set incorrectly by mistake or has become incorrect as a result of structural changes to the building or its surroundings. If the other co-owners agree, the agreement must be publicly certified. The possibilities to enforce the change with a lawsuit against the will of the other condominium owners are very limited.

As an alternative to the circumstantial value quota change in a house without a meter, clarify whether it is possible to install meters retroactively and distribute the costs according to the source.

Costs for the common components

All water, electricity and heating costs as well as repair or renovation costs of common components are settled according to the distribution key, usually according to the value quota. What is considered common is determined by each community itself when it establishes condominium ownership. The law defines these components as common:

  • Everything that belongs to the ground of the property and is not a building: the common garden, the playground, driveways and footpaths, outdoor parking spaces, walls and fences or retaining walls.
  • Elementary components for the construction and strength of the entire building: for example, the exterior façade including the exterior of balconies, loggias and verandas, exterior antennas, roof terraces, window fronts replacing a façade, common house entrances or chimneys.
  • Common facilities and equipment: for example, storerooms, ducts, lifts and vents, stairwell, laundry and drying room or central heating.

Houzy Advice

Good to know

Condominium owners usually transfer advance payments for ongoing maintenance into a joint account every three or six months. Once a year, the cost shares are calculated on a pro rata basis and offset against the payments on account.

Exceptions to the costs distribution

The value quota is never 100 per cent fair. The co-owner on the ground floor never needs the lift, but he often has guests who park in the shared visitors' area. The co-owner on the third floor uses the lift several times a day, but her guests come by public transport or visit her on foot. This usually balances out. That is why the fixed distribution key is not always fair, but it is suitable for everyday use and pragmatic. The condominium regulations can provide for exceptions to the distribution of costs according to value. This makes sense for radio and television reception fees (Serafe), for example. Such decisions require a majority of the condominium owners, amendments to the regulations require a qualified majority (more than half of the votes and value quotas).

Major repairs and renovations

Condominium owners should put money aside at an early stage for major expenses such as repairs or renovations to common components. After about 25 years, the first major renovations are due, for example the complete renovation of the roof, the façade, the building envelope or the building services. 80 per cent of condominium owners' associations in Switzerland have set up a so-called renewal fund for this purpose, although the law does not prescribe one.

Major renovations are expensive. This is why condominium owners should pay enough money into the renovation fund.

How much belongs in the renovation fund?

Most condominium owners' associations set aside 0.2 to 0.5 per cent of the building insurance value of their property per year; the Swiss Condominium Owners' Association recommends 0.3 per cent. The amount of the deposits is usually based on the value ratio. The earlier a condominium owners' association starts making deposits, the lower the financial burden per year. So it is best to start when condominium ownership is established. All deposits are considered maintenance costs and can be deducted from the imputed rental value and thus from the taxable income.

Thanks to regular contributions to the renovation fund, you can spread the financial burden of expensive renovations over many years. With our renovation fund calculator you can estimate the renovation costs, check the coverage of the renewal fund and calculate your optimal annual contribution. You can share all the results with the other co-owners with just one click, for example before the next condominium owners' meeting.
