Introduction: What are maintenance reserves and why are they so important?

Maintenance reserves are the financial cushion of a homeowners’ association (WEG). They are used to finance necessary long-term repairs and modernizations to the common property. But why are they so important in 2025?

Rising construction costs, stricter legal requirements in the area of energy efficiency and the increasing need to renovate older buildings are putting many condominiums under pressure. Without sufficient reserves, there is a threat of special levies, which often represent an enormous financial burden for owners. Forward-looking planning and the right amount of reserves are therefore essential to ensure that the property retains its value and to avoid unforeseen costs.

In this article, we explain why maintenance reserves are essential for condominiums, how they are formed and what mistakes should be avoided.

The role of maintenance reserves in the WEG

Maintenance reserves are the foundation for the financial stability of a condominium owners’ association. They ensure the long-term preservation of the value of the common property, such as the roof, façade, stairwells or elevators, and make it possible to carry out planned and unforeseen repairs without placing an additional financial burden on the owners.

Why are reserves indispensable?

1. planning security: reserves create a reliable basis for financing necessary measures without having to decide on special levies at short notice.

2. maintaining the value of the property: regular maintenance increases the value of the property and prevents damage from increasing or the attractiveness of the building from declining.

3. obligation under the German Condominium Act (WEG): Communities of owners are legally obliged to build up reserves to provide for necessary repairs and modernization.

Relevance in the year 2025

Reserves are becoming increasingly important, especially in today’s world. Rising energy costs and stricter laws on energy efficiency (such as renovation obligations for older buildings) make investments unavoidable. Without sufficient reserves, these measures can quickly become a financial burden.

How are maintenance reserves formed?

Maintenance reserves are formed on the basis of various factors that take into account the condition and needs of the property. Both legal requirements and the resolutions of the owners’ meeting play a key role here.

1. basis of the calculation

The amount of the reserves is generally determined by the following criteria:

Age of the property: Older buildings often require higher reserves due to the increasing need for renovation.

Size and condition: Extensive common areas or known defects in the building require a more precise calculation.

Future projects: Measures already planned, such as the renewal of a heating system, influence the amount of reserves.

2. typical calculation methods

Property management companies and condominiums often use tried and tested methods to determine the necessary amount of reserves:

Peters’ formula: This method is based on the age and replacement cost of the building and enables a precise calculation of the annual reserve requirement.

Individual estimates: Property management companies often use empirical values to plan reserves, especially if the building has special features.

3. resolution by the owners’ meeting

The amount of the reserves is decided at the owners’ meeting. The property management company usually submits a proposal based on an analysis of the building situation. The owners then decide whether and to what extent the contributions should be adjusted.

Relevance of regular adjustment

A common mistake is to set the reserve amount once without adjusting it later. In order to respond to rising construction costs and legal requirements, reserves should be reviewed regularly and increased if necessary.

Common mistakes when building up reserves and how to avoid them

The formation of maintenance reserves is crucial for the financial security of a condominium. However, in practice, mistakes often creep in that can lead to problems in the long term. Here are the most common pitfalls and how you can counteract them:

1. reserves too low

The problem: the monthly contribution to the reserves is often deliberately kept low in order to keep the running costs for the owners low. However, this means that the funds are not sufficient for major renovations.

The solution: A realistic calculation based on the value of the building and the expected refurbishment requirements is crucial. A regular review by the property management company helps here.

2. lack of longevity

The problem: reserves are often only planned for the near future. Long-term costs such as roof renovations or the replacement of elevators are neglected.

The solution: A maintenance plan that covers the next 10 to 20 years provides clarity about future requirements and the necessary financial resources.

3. irregular adjustment of reserves

The problem is that the reserve amount is rarely adjusted after it has been set, even though construction costs and legal requirements change regularly.

The solution: Reserves should be reviewed annually and, if necessary, adjusted to the current situation by resolutions of the owners’ meeting.

4. lack of transparency towards owners

The problem is that many owners are not clear about the amount and purpose of the reserves, which can lead to resentment and conflicts.

The solution: The property management company should regularly provide the owners with a detailed reserves report that transparently presents planned measures and the current status of the funds.

5. confusion with special allocations

The problem: owners often equate reserves with special levies and consider them to be interchangeable. However, reserves are planned for the long term, while special levies are usually required for unforeseen events.

The solution: a clear distinction and communication help to avoid misunderstandings and strengthen confidence in the reserves strategy.

What are maintenance reserves used for?

Maintenance reserves are used exclusively to finance measures that affect the common property. Their use is clearly regulated in order to maintain the value and functionality of the property in the long term. But what specific measures are financed from them and what is the difference to special allocations?

Typical measures financed from reserves

1. repairs and refurbishments:

– Roof repairs, facade renovations and the replacement of defective windows in the common property.

– Repairs to heating systems or pipe networks.

2. modernizations and upgrades:

– Installation of modern heating systems, e.g. conversion to heat pumps or solar thermal energy.

– Improvements in energy efficiency, e.g. through insulation measures or the replacement of windows.

3. regular maintenance work:

– Maintenance and repair of stairwells, outdoor facilities or communal areas such as laundry rooms.

– Testing and maintenance of elevators, fire protection systems or electrical systems.

Difference to special allocations

Maintenance reserves:

Reserves are set up for the long term and serve to cover foreseeable costs. Owners pay regular contributions that are determined on the basis of a resolution.

Special allocations:

Special levies are decided at short notice if unexpected or major measures are necessary that are not covered by the reserves. These can represent a considerable financial burden for owners and should therefore be avoided wherever possible.

Advantages of a well-managed reserve

Financial security: communities of owners do not have to raise new funds for every measure.

Smooth implementation: Urgent repairs or refurbishments can be carried out promptly without delays due to financing gaps.

Value retention and appreciation: Regular maintenance and modernization keep the property attractive and marketable.

Planning security for 2025 and beyond

The year 2025 will bring new challenges for condominium owners’ associations, making forward-looking planning of maintenance reserves even more important. Rising costs, new legal requirements and the growing need for renovation require a clear plan and a sustainable strategy.

1. increasing requirements due to legislation

Energy efficiency requirements: The legal obligation to reduce CO₂ emissions is putting pressure on many older buildings. Measures such as façade insulation or switching to energy-efficient heating systems are cost-intensive but unavoidable.

Climate protection measures: Although subsidy programmes support modernization, they often only cover part of the costs. Reserves help to finance the condominium’s own contribution.

2. inflation and increase in construction costs

Cost development: Construction costs have been rising continuously for years, and material prices are also unpredictable. Reserves that were planned several years ago are often no longer sufficient to cover current market prices.

Prevention: Regularly reviewing and adjusting the level of reserves can help to avoid financial bottlenecks.

3. long-term planning is the key

Maintenance planning: A systematic survey of the building stock, including an analysis of age and condition, enables a realistic forecast of future costs.

Digital tools: Property management companies and owners’ associations can access software solutions that calculate long-term costs and create transparency.

Reserve for unforeseen events: In addition to planned measures, a buffer should be planned for unexpected events, e.g. storm damage or sudden failures of technical systems.

Relevance for owners and condominiums in 2025

The requirements for condominiums are becoming increasingly complex. Those who plan their reserves strategically today can not only reduce financial burdens in the future, but also benefit from the increased attractiveness and value retention of the property. Transparent and intelligent planning is therefore a win-win situation for all owners.

Conclusion: Maintenance reserves secure the future of the WEG

Maintenance reserves are an indispensable instrument for ensuring the long-term stability and value retention of a property. They offer planning security, protect owners from financial bottlenecks and enable the timely implementation of necessary repairs and modernizations.

In 2025, their importance is greater than ever: rising construction costs, stricter legal requirements and the requirements for energy-efficient buildings make strategic and forward-looking reserve formation essential. Communities of owners that regularly review their reserves, draw up long-term maintenance plans and rely on transparency and professional support are ideally equipped to meet the challenges of the future.

A well-managed reserve is not only a financial safety net, but also a sign of responsible management of the common property. It ensures that the property not only retains its value, but also remains attractive for future generations.
