Contributions and weighting factors in owners’ associations: what they are for and how they affect voting and expenditure
Fees and coefficients in owners’ associations usually come up when a special levy needs to be paid, a budget approved, a majority calculated at a general meeting, or when discussing why one neighbour pays more than another. And, although it may seem like a very technical matter, it actually affects almost everything of importance within a homeowners’ association: expenses, rights, voting, building works, the reserve fund, debts and even how certain agreements are interpreted.
The most common question is a simple one: “If we all use the entrance hall, the lift or the swimming pool, why don’t we all pay the same?” The short answer is that the community’s costs are not necessarily divided on a per-person or per-property basis, but according to the share of ownership set out in the deed of incorporation, unless there is a special rule applicable to certain expenses. This share is usually expressed as a percentage or in hundredths and represents the weighting of each flat, commercial premises, garage or outbuilding within the property as a whole.
In this article, we’ll explain, in plain language, what participation quotas are, how the coefficients are calculated, what role they play in community charges, how they affect voting at general meetings, and why it’s a good idea to manage them effectively using a residents’ association app such as Onzane.
What is a participation share in a residents’ association?
The participation share is the percentage allocated to each property within the community. It can apply to flats, commercial premises, storage rooms, garage spaces or outbuildings, depending on how the building is structured. In practice, it is a way of expressing how much ‘weight’ each property carries within the total.
The Horizontal Property Act states that each flat or commercial premises is assigned a share in proportion to the total value of the property. This share serves as a basis for determining each property’s share of the community’s expenses and benefits. In other words: it is normally used to allocate expenses and also to calculate the economic weight of a vote.
For example, if a flat has a coefficient of 4.25 per cent, that flat will, as a general rule, bear 4.25 per cent of the common expenses allocated on the basis of the coefficient. If the community’s annual budget is 60,000 euros, your theoretical contribution towards this would be 2,550 euros per year, unless there are individualised expenses or special rules.
The contribution is not made up each year, nor is it changed simply because a neighbour uses the lift more or less frequently. It is set out in the title deed of the block of flats, which is the community’s founding document. Therefore, when there are serious doubts about participation coefficients, the first step should not be to discuss the matter in the WhatsApp group, but to review the title deed, the articles of association and any agreements that have been duly registered or approved.
How a participation coefficient is calculated
The participation fee is set taking various criteria into account. The Condominium Act refers to the usable floor area of each flat or premises in relation to the total area of the building, its internal or external location, its position, and the use that can reasonably be expected to be made of the common services or facilities.
This explains why two flats in the same building may have different coefficients. It is not always just the number of square metres that is taken into account. Other factors may also play a part, such as whether a flat faces the outside, has a terrace, includes annexes, is in a better location, is a commercial premises with independent access, or is expected to use certain common services differently.
In simple buildings, the coefficients are usually easy to understand. In large housing developments, communities comprising several phases, garages, storage rooms, swimming pools, sports facilities, commercial premises or sub-communities, the allocation can be considerably more complex. This is where general coefficients, staircase coefficients, garage coefficients, swimming pool coefficients or specific rules for certain services come into play.
That is why at Onzane we place great importance on ensuring that the information for each property is well structured. A community management platform must not only know who lives in each property; it must also be able to manage properties, owners, residents, coefficients, permits, bookings, communication and documentation, because everything is interconnected.
Share of ownership and community charges
The most common application of these allocation factors is the apportionment of expenses. The general rule is that each owner must contribute, in accordance with their share or as specifically stipulated, to the general expenses necessary for the proper upkeep of the property, its services, charges and responsibilities.
This includes expenses such as cleaning, maintenance, insurance, administration, electricity for communal areas, caretaker services, routine repairs, building upkeep, the lift, gardening and communal services. However, it is important to note that not all expenses have to be apportioned equally in every case if the title deed, the articles of association or a valid agreement stipulate otherwise.
For example, there may be communities where commercial premises do not contribute to certain stairwell expenses if this is provided for. Or garages that have their own expenses. Or communal areas for the exclusive use of a specific phase within a housing development. There may also be individualised charges, such as top-ups, metered supplies or services paid for on a pay-as-you-go basis.
The key is not to confuse ‘I think it’s fair’ with ‘it has been properly approved’. If a community wishes to change the way an expense is allocated, it must check whether that change affects the title deed or the articles of association. In many cases, altering contributions or allocation rules requires a qualified majority or even unanimity, depending on the type of amendment. This is no minor matter.
To avoid confusion, it is advisable for bills, estimates and final statements to be easy to understand. We have already discussed on this blog how to communicate consumption costs to residents of a housing community, and the same principle applies here: the clearer the origin of the amount, the fewer disputes there will be later on.
Fees, special levies and extraordinary works
Extraordinary levies are another area where contribution coefficients are very important. When the community needs to fund a project or an extraordinary expense, the amount is normally allocated according to the contribution coefficient, unless there is a special rule applicable to that particular expense.
Let’s consider a façade repair costing 100,000 euros. If a flat has a share of 3 per cent, its share would be 3,000 euros. If another has a share of 6 per cent, it would pay 6,000 euros. It may seem harsh, but it reflects the allocation system for flat ownership: those with a larger share in the property bear a greater proportion of the common charges.
However, not all works are treated in the same way. Necessary maintenance works, accessibility improvements, non-essential improvements, energy efficiency measures or new installations may be subject to different rules regarding approval and cost allocation. That is why it is important to distinguish between two questions: what majority is required to approve the works and how their cost is shared.
At many meetings, these two issues get mixed up, and that’s where the problems begin. A resolution may have been properly approved but poorly settled. Or a special levy may have been correctly calculated, but the resolution that gave rise to it did not achieve the necessary majority. That is why Onzane is designing its online voting module for housing associations, taking into account owners, service charges, majorities and arrears. For sensitive resolutions, counting votes ‘by eye’ is not enough.
How coefficients affect voting
In a homeowners’ association, simply counting people is not always enough. Many majorities are calculated using a dual system: owners and contribution shares. In other words, a majority must be achieved both by the number of owners and, additionally, by contribution shares.
This is a fundamental point. If there are 40 owners in a community, 21 votes might seem like a sufficient majority. But if those 21 owners represent only 38 per cent of the shares, the resolution may not meet the required financial majority. The opposite can also happen: a small number of owners with a high coefficient cannot always push through a resolution if they do not achieve the necessary personal majority.
The Horizontal Property Act uses this system for many decisions. Some resolutions require a simple majority of owners and shares, others three-fifths, others a third, and others unanimity. If you wish to explore this topic in more depth, it makes sense to refer to a specific guide on majorities in owners’ associations, as not all resolutions are approved in the same way.
For the vote to be valid, the minutes must clearly state who voted in favour, who voted against and what shareholdings they represent, where this is relevant to the validity of the resolution. The owners represented and their shares must also be listed. This is not mere red tape: it is what enables you to verify whether the resolution has been properly adopted.
What happens with owners in arrears
Arrears also affect the calculation of majorities. Owners who, at the start of the meeting, are in arrears with the owners’ association and have not challenged these debts in court or set them aside may take part in the deliberations, but do not have the right to vote. Furthermore, neither they nor their share are counted towards the required majorities.
This has a very important practical consequence: before voting, the owners’ association must know which owners are barred from voting. And it is not enough to have a rough idea. The notice of the meeting must include a list of owners who are in arrears and warn of the possible deprivation of the right to vote.
If arrears are miscalculated, the majority may also be miscalculated. For example, in a three-fifths vote, correctly excluding owners deprived of their voting rights can alter the denominator against which the result is measured. That is why, when dealing with arrears, it is advisable to work with up-to-date data rather than outdated lists.
Onzane allows you to manage arrears from various sources depending on the community’s procedures: a manual system, an imported list or an accounting module. This information can be applied to processes such as votes, reserves or permits, always within the limits approved by the community and in compliance with legal requirements. You can also find out more about this topic in the article on how to manage arrears and restrict access to communal areas for residents in arrears.
Shared areas, commercial premises and garages: where conflicts often arise
The most common conflicts do not usually arise from standard flats, but from properties requiring special treatment: commercial premises, garage spaces, storage rooms, flats with terraces, ground-floor flats with courtyards, penthouses, annexes or properties that do not use certain communal services.
A commercial premises with direct access from the street may question why it has to pay for the lift. A garage space may have concerns about the general insurance. A ground-floor flat may dispute the cost of staircase maintenance. A flat with a private terrace may wonder whether a repair should be paid for by the owner or the owners’ association. And an owners’ association comprising several phases may face problems if all expenses are lumped together without distinguishing which services each block uses.
There is no one-size-fits-all answer for every situation. The deed of incorporation, the articles of association and the valid agreements of the owners’ association must be reviewed. If these documents state that a commercial premises is exempt from certain expenses, this must be respected. If they do not specify this, the general rule may mean that the owner must contribute even if they do not directly use the service, because in a block of flats, payment is not always based solely on usage.
Good record-keeping is very helpful here. If each resident interprets the rules from memory, the discussion will never end. If the owners’ association has its documents organised in a centralised system, the administrator, the chairperson and the owners can consult the actual basis for each allocation.
Can a contribution be changed?
Yes, but it is not something to be done lightly. The share forms part of the articles of association and, as a general rule, modifying it requires compliance with the relevant legal requirements. The Condominium Act itself states that improvements to or alterations of individual flats or premises do not, in themselves, alter the allocated share, and that it may only be varied in accordance with the law.
This means that renovating a flat, changing the flooring, upgrading the kitchen or reconfiguring the interior layout does not automatically change the share. It is a different matter altogether if there is a separation, grouping, division, alteration of the building or amendment to the title deed, which may indeed require an adjustment to the shares.
In practice, changing coefficients usually requires a very careful agreement, technical and legal advice, and in many cases registration with the Land Registry so that it is effective against third parties. If the owners’ association discovers that the historical coefficients are incorrect, it is not advisable to simply cobble together a new spreadsheet in Excel and start charging differently. The prudent course of action is to review the documentation, prepare a formal proposal and have it approved through the proper channels.
Common mistakes when managing fees and coefficients
There are several errors that recur in owners’ associations and property management firms:
- Confusing a property with its owner. One person may own several properties, and a single property may be owned by several people.
- Counting only personal votes. Many decisions also require the calculation of participation quotas.
- Using out-of-date allocation factors. Following subdivisions, amalgamations or changes to the land registry, data may need to be revised.
- Failing to distinguish between general and specific expenses. Some expenses may be subject to different allocation rules.
- Failing to record contribution shares in the minutes. If the contribution share is relevant to the majority, it must be clearly stated.
- Treating owners with and without voting rights equally. Owners in arrears who are deprived of their voting rights are not counted equally in the majority.
- Relying on loose sheets of paper. If the calculation is on a sheet that only one person can understand, the risk of error increases.
Digitising the owners’ association is not just about having a nice-looking app. It’s about ensuring that important data is interconnected. Properties, owners, residents, allocation coefficients, permits, reserves, notices, incidents and documents should not exist in isolation from one another. For property managers, this is particularly important: good property management software should reduce operational errors, not create more manual work.
How Onzane helps manage this information
Onzane is designed for residents’ associations that need to organise their day-to-day management without turning every task into a chain of emails, spreadsheets and lost messages. When it comes to fees and contribution rates, the platform helps by allowing information to be structured around the property, not just around the user logging into the app.
This is key. A resident may be an owner, a tenant, an authorised family member or a guest user. However, the contribution is linked to the property. Therefore, when it comes to expenses or votes, the platform must clearly distinguish between who lives there, who decides, who pays, who can book a communal area and who has access to specific documentation.
Furthermore, the features for notices, incidents, bookings and payments ensure that management does not rely on informal conversations. If a special levy is approved, it is communicated. If there is an incident, it is recorded. If access is restricted due to non-payment, this is applied judiciously. If a resolution is put to a vote, the result is calculated taking into account owners, fees and majorities.
The most interesting part will come with the voting. In resolutions where contribution amounts are significant, the system must be able to freeze the register of owners, apply late payment penalties, record proxies, calculate majorities by owner and coefficients, retain evidence and generate an exportable record for legal purposes. This is not excessive formalism. It is what enables a community to make important decisions with greater certainty.
Conclusion: coefficients are not merely an administrative detail
Contributions and participation coefficients are a central element in any owners’ association. They are used to allocate expenses, calculate additional charges, measure the economic weight of votes, verify majorities and understand why not all owners pay exactly the same amount.
When they are properly documented, hardly anyone even notices them. When they are poorly managed, conflicts arise with every budget, every building project and every meeting. That is why it is important to treat them seriously: review the articles of association, apply the allocation rules correctly, record the contributions in the minutes where appropriate, and use digital tools to minimise errors.
Onzane helps bring this management process into a clearer, more traceable and connected environment. For owners’ associations, property managers and chairpersons, fully understanding the allocation coefficients is not just a legal matter. It is a way to avoid disputes, improve transparency and make better decisions.
