Have a renovation plan created for an inherited house
Have you inherited a house and are now faced with a mountain of questions regarding its condition, costs, and legal obligations? Many heirs feel overwhelmed by the complexity of the situation. However, with the right tools, you can turn this challenge into a clear opportunity.
With access to Google, BORIS, and Deep Research.
An individual renovation roadmap (iSFP) is often essential for heirs to meet the legal requirements of the Building Energy Act (GEG) within the two-year deadline.
The costs for an iSFP are subsidised by the government by up to 50%, and the plan itself unlocks additional bonus grants of 5% for renovation measures.
The iSFP serves as an objective basis for decision-making, enhances transparency in sales, and helps to specifically increase property value through planned, efficient measures.
Inheriting a property often brings uncertainty. The Building Energy Act (GEG) puts pressure on new owners to meet energy standards within two years. An individual renovation roadmap (iSFP) serves as your most important strategic guide in this situation. It analyzes the current status, suggests sensible modernization steps, and secures government funding for you. Instead of acting aimlessly, you get a data-driven foundation to strategically increase the value of your property—whether you want to sell, rent, or move in yourself.
Have you inherited a house that was built before 1 February 2002? Then, as the new owner, you are often required by the Building Energy Act (GEG) to undertake certain energy renovations. You have only two years to implement these measures, such as insulating the top floor ceiling or replacing outdated boilers. Failure to comply can lead to fines of up to 50,000 euros. A professionally created renovation roadmap for your inherited house is therefore not an optional step, but a necessity. It protects you from legal consequences and poor investments. With a clear plan, you can not only meet legal requirements but also make informed decisions on how to proceed. Inform yourself at an early stage about what to consider with an inherited property. This strategic foresight is the first step to fully realising the potential of the property.
What exactly is an Individual Renovation Roadmap (iSFP)? It is a detailed document created by a certified energy consultant following an on-site analysis of your property. The iSFP provides you with an understandable overview of the current energy status and indicates which renovation measures are technically and economically viable. Instead of relying on gut feeling, you receive a clear, prioritised list of recommendations for action. The plan not only highlights potential savings but also serves as recognised evidence for funding programmes. It is the foundation for a targeted Renovation Potential Report and ensures that every investment contributes to increasing value. This makes the iSFP your most important tool for structuring renovations logically and efficiently.
The creation of an iSFP for a single-family house typically costs between 1,300 and 1,700 euros. However, this investment is significantly offset: The Federal Office for Economic Affairs and Export Control (BAFA) subsidizes the creation with up to 50 percent, a maximum of 650 euros for single and two-family houses. The real financial benefit, however, lies in the future. Having an iSFP in hand increases the grant rate for many renovation measures on the building envelope by an additional 5 percent. Furthermore, the amount of maximum eligible costs doubles from 30,000 euros to 60,000 euros per residential unit. Thus, the iSFP bonus alone can make a funding difference of several thousand euros. A professional Funding Check is therefore an integral part of the process. The iSFP is thus not only a plan but a direct key to significant financial advantages.
The path to your individual renovation roadmap is clearly structured and ensures you receive maximum funding. Follow these five steps to make the process efficient:
Find a certified energy consultant: Look for an energy efficiency expert listed by BAFA. Only they can issue a grant-eligible iSFP.
Apply for consultation funding: The energy consultant will apply directly to BAFA for a subsidy for the energy consultation on your behalf.
Conduct an on-site inspection: The expert will analyze the building fabric, the heating system, and the insulation of your inherited property directly on site.
Receive renovation roadmap: You will receive two key documents: 'My Renovation Roadmap' with a visual overview, and the 'Implementation Guide' with technical details for craftsmen.
Make a decision and implement measures: Use the data-based foundation to decide whether to renovate, sell, or rent out. You have up to 15 years to implement the measures to benefit from the funding advantages.
A first step can be a digital check to determine the renovation needs online and be well-prepared for the discussion with the expert.
An inherited house presents you with a choice: sell, rent out, or move in yourself? The renovation roadmap provides the necessary data foundation for each of these options. Planning to sell, the iSFP is an invaluable selling point. It creates transparency for potential buyers, documents the condition objectively, and can significantly shorten the sales time. Buyers not only see the renovation needs but also the already secured funding advantages. This can improve the negotiation margin in your favour by 5-10%. If you decide on renovation and then renting out or living in it yourself, the iSFP serves as an exact blueprint. It helps you realistically calculate the renovation costs and avoid bad investments. Thus, a complex decision becomes a secure, value-enhancing strategy.
Without a strategic plan, heirs risk making costly mistakes that decrease the property's value rather than increase it. One of the most common pitfalls is renovating in the wrong order, leading to construction damage or doubled costs. Many also overlook the opportunity to use subsidies, thereby missing out on up to €12,000 in government grants. Another mistake is inadequate documentation, which can create mistrust among buyers during a future sale. An iSFP protects you from these risks by providing a clear, optimised path. It is the best insurance against unforeseen expenses. Before you begin, you should thoroughly examine the renovation costs for your inherited house. This ensures that your approach not only meets legal requirements but also sustainably maximises your property's value.
The decision to create a renovation roadmap for an inherited house is one of the most crucial choices you can make as an heir. It is far more than just a technical document; it is your strategic guide to financial security and value enhancement. The iSFP transforms the legal obligations of the GEG into an opportunity, securing you thousands of euros in subsidies and providing an indisputable basis for decisions regarding sale, rental, or personal use. Instead of acting in uncertainty, invest in clarity and control. With a data-driven plan in hand, a complex inheritance becomes a manageable and profitable future investment.

Do I have to implement the measures proposed in the renovation roadmap?
No, the iSFP is a recommendation and does not oblige you to implement it. It merely shows you the most technically and economically sensible path. You decide which measures you want to undertake and when, but can benefit from funding advantages within 15 years.
Who is allowed to create an eligible renovation roadmap?
Only energy efficiency experts (EEE) certified by the Federal Office for Economic Affairs and Export Control (BAFA) are entitled to create an iSFP recognized as a basis for government subsidies.
What happens if I ignore the renovation obligation as an heir?
If you do not implement the renovation measures prescribed in the Building Energy Act (GEG) within the two-year period following an inheritance, authorities may impose a fine of up to 50,000 euros.
Does the renovation obligation apply even if I have lived in the inherited house myself?
There is an important exception: If you, as the owner, lived in a single or two-family house yourself before 1 February 2002, you are exempt from the renovation obligation upon change of ownership. However, this exception does not apply to heirs who have not previously lived there.

Auctoa offers you AI-supported analyses to provide an initial, quick assessment of the renovation needs and value potential of your inherited property. With our ImmoGPT, you can clarify initial questions and optimally prepare for a meeting with an energy advisor to make data-based decisions.
Do eligible costs really double with an iSFP?
Yes, for measures concerning the building envelope (e.g., insulation, windows), the maximum eligible investment costs per residential unit and calendar year increase from 30,000 euros to 60,000 euros if the measure is part of a valid iSFP. This significantly maximizes your potential subsidy.
