The topic briefly and concisely
Heirs of properties built before 2002 must carry out energy renovations within two years according to the Buildings Energy Act (GEG).
The obligations include the replacement of boilers over 30 years old, insulation of the top floor ceiling, and insulation of heating pipes.
Exceptions apply, among others, for long-term owner-occupiers and listed buildings; non-compliance may result in fines of up to 50,000 euros.
The inheritance of a property is often associated with unexpected obligations. One of the most important is the obligation to renovate inherited houses in Germany as stipulated in the Building Energy Act (GEG). Many heirs are unaware that they are legally obliged to carry out energy-related modernisations when there is a change of ownership. These measures must be implemented within a period of two years and, depending on the condition of the building, can incur costs of several tens of thousands of euros. This guide explains precisely which obligations apply to you, what exceptions exist, and how you can make the right strategic decisions for your property inheritance.
Legal Framework: The Building Energy Act (GEG) as a Guideline for Heirs
Have you inherited a house that was built before 1 February 2002? Then, as the new owner, you are subject to the Building Energy Act (GEG). The GEG aims to reduce the energy consumption of buildings and applies whenever there is a change of ownership — this includes inheritance or gifting. The regulations are designed to ensure that older existing properties are gradually improved in terms of energy efficiency. For you as an heir, this means a legal obligation to retrofit in order to meet certain energy standards. The central deadline for this is two years after the entry in the land register. This timeframe gives you the opportunity to carefully plan the necessary steps. The specific requirements are set out in Sections 47, 71, and 72 of the GEG and mainly concern heating and insulation. A clear understanding of these legal basics is the first step to correctly assess the requirements for your inherited property.
Concrete measures: These 3 renovations are mandatory for heirs
The GEG does not mandate a complete renovation but focuses on three key areas with high savings potential. Within a two-year period, you must implement the following measures:
Replacement of outdated boilers: Oil and gas boilers that are over 30 years old and not based on low-temperature or condensing technology must be replaced. This obligation affects constant temperature boilers that operate with inefficiently high temperatures most of the year.
Insulation of the top storey ceiling: If the roof above is not insulated and the attic is unheated, the top storey ceiling must be insulated. The target is a thermal transmittance (U-value) of no more than 0.24 watts per square metre and Kelvin. Alternatively, the roof itself can also be insulated.
Insulation of pipes: In unheated rooms, such as the cellar, all accessible heating and hot water pipes must be insulated to minimise heat loss.
Compliance with these obligations is often checked by the chimney sweep during the fireplace inspection. Early planning helps you keep the costs of the energy renovation within budget and ensure that tradespeople are commissioned in good time.
Exceptions to the Rule: When the Renovation Duty for Heirs Ceases to Apply
Not every heir of an older house is automatically obliged to renovate. The law provides several important exceptions that can exempt you from the costly measures:
Long-term self-use: The most common exception concerns heirs who inherit a one- or two-family house that they have already occupied themselves before 1 February 2002. In this case, the inheritance is not considered a relevant change of ownership under the GEG.
Listed building: If the inherited building is a listed building, the requirements of the GEG could affect the preservation of the historical substance. In such cases, heritage protection takes precedence, and the obligation to renovate is waived entirely or partially.
Economic unreasonableness: If the costs of the renovation measures exceed the value of the property or your financial capacity, an exemption due to undue hardship can be applied for. However, this requires detailed evidence.
Carefully check whether any of these exceptions apply to your situation. This could save you considerable investments before you consider modernising the old building to be energy-efficient.
Costs and Funding: The Financial Aspect of Renovation Requirements
The renovation obligation for inherited houses in Germany is associated with direct costs. You can expect to pay between 6,000 and 12,000 euros for the replacement of a boiler, while insulating the top floor ceiling can cost between 2,000 and 5,000 euros. Pipe insulation is the most affordable measure, costing between 500 and 1,500 euros. These investments quickly add up to over 20,000 euros. However, you do not have to bear this burden alone. The Federal Funding for Efficient Buildings (BEG) offers financial support through the KfW Bank and BAFA. Heirs can receive low-interest loans (e.g., KfW Programme 261) or direct grants for heating replacement covering up to 45% of the costs. A professional funding check can help you secure maximum support and significantly reduce your financial burden.
Strategic options: Renovate, sell, or live in it yourself?
As an heir, you're faced with an important decision that has financial implications. Should you renovate the property for personal use or potentially rent it out at a higher rate? Or would you prefer to sell the house in its unrenovated state? A sale without renovation is possible, but the obligation to renovate then transfers to the buyer, who must also complete the measures within two years. This generally reduces the achievable sale price by more than just the pure renovation costs. A data-driven property valuation is your digital guide here. It shows you the market value in both scenarios – renovated and unrenovated. This allows you to make an informed decision on whether the investment is worthwhile. Our ImmoGPT chat can offer an initial assessment and demonstrate how to best protect the value of your inheritance. Don't make gut decisions when it comes to whether you should sell or rent the inherited house.
Risks of Inaction: Avoid Fines and Depreciation
The renovation obligation anchored in the Building Energy Act is not merely a suggestion. Ignoring the requirements constitutes an administrative offence, which can result in substantial penalties. The competent state authorities can impose fines of up to €50,000 if the prescribed measures are not implemented within the deadline. Even if no inspection takes place, failing to renovate leads to a long-term depreciation in the property's value. Moreover, liability issues may arise in a future sale if you do not inform the buyer transparently about the existing obligations. To avoid these risks, it is crucial to educate yourself early and create a clear plan. Investing in an energy certificate and professional consultation is the first step to being legally and financially secure.

FAQ
What is meant by the obligation for heirs to carry out refurbishment?
The obligation for heirs to undertake renovations is a legal requirement under the Building Energy Act (GEG). It mandates new owners of older properties to carry out certain energy efficiency upgrades, such as replacing the heating system or insulating the top storey ceiling, within two years after the inheritance.
What costs will I incur with an obligation to renovate?
The costs vary depending on the measure. Expect approximately €6,000-12,000 for a new boiler, €2,000-5,000 for ceiling insulation, and €500-1,500 for pipe insulation. However, there are government subsidies (KfW, BAFA) that can significantly reduce these costs.
Is there financial assistance for the renovation of an inherited house?
Yes, heirs can take advantage of government funding to fulfil the obligation to renovate. The Federal Funding for Efficient Buildings (BEG) provides low-interest loans through the KfW bank and substantial grants through the BAFA, especially for switching to renewable heating systems.
What if I can't afford the renovation?
If the renovation costs represent an undue hardship, meaning they are economically unreasonable, you can apply for an exemption from the obligation at the relevant authority. However, this must be well justified and proven.
Do I need to renovate even if I don't live in the inherited house myself?
Yes, the obligation to renovate is tied to the change of ownership, not to its use. This means it also applies if you rent out the inherited property or leave it vacant. The only exception regarding usage is if you, as the heir, already lived in it before the cut-off date of 1 February 2002.
How can I find out if my inherited house needs renovating?
An energy consultant or a chimney sweep can check the condition of the property. A look at the energy certificate, which is mandatory when changing ownership, also provides initial clues. For a precise analysis and action recommendations, including strategic decisions, a data-supported assessment from Auctoa is helpful.
