The topic briefly and concisely
The development costs (€15,000–€50,000) are a mandatory contribution to the municipality, which can pass on up to 90% of the costs to owners.
The legal basis is the Building Code (BauGB); details are regulated by the municipal statutes, which you should definitely review.
A complete development is a prerequisite for building permission and significantly increases the property value.
Did you know that the cost of developing a plot can account for up to 15% of the total construction costs? Many builders underestimate this crucial item, leading to unexpected financial bottlenecks. Careful planning of development in new construction is not rocket science, but the foundation for a successful building project. It not only secures the building permit but also sustainably increases the value of your property. In this guide, you will learn how to calculate costs accurately, avoid legal pitfalls, and make strategic decisions to save your budget.
Understanding the Foundation: What Does Development Mean in New Construction?
The development transforms a piece of undeveloped land into a buildable plot. According to the Building Code (BauGB), a plot is only ready for new construction when it is connected to the public supply and transport network. Without this step, you will not receive a building permit. There are two key areas: transport development and technical development. Transport development ensures access to your property via roads, pavements and lighting. Technical development includes connection to essential networks such as water, sewage, electricity, and telecommunications. Therefore, thorough planning of the development is the first step towards a value-stable home. The distinction is crucial as the cost distribution between you and the municipality varies depending on the measure.
Identifying cost drivers: What do development costs consist of?
The total costs for full development can quickly range between 15,000 and over 50,000 Euros, depending on the region and effort involved. These costs are usually calculated per square metre of the property and can range from 30 to 120 Euros per m². The exact amount depends heavily on the regulations of your municipality. A detailed breakdown helps identify the largest items:
Traffic development: This includes the construction of roads, pavements, and the installation of street lighting.
Technical development (public): This covers the connection to central supply and disposal networks. It includes drinking water (approx. €2,000–5,000), sewage systems, electricity (approx. €2,000–3,000), and gas (approx. €2,000).
Telecommunication: Connection to the telephone and internet network costs about 600 to 800 Euros.
Private development: This includes all lines from the property boundary to your house. These costs are your responsibility and you contract the suppliers directly.
An accurate calculation of property costs must take these variable factors into account. The complexity of these costs makes a professional assessment of building land potential essential to avoid financial surprises.
Mastering Legal Foundations and Cost Allocation according to the BauGB
The legal basis for the collection of development contributions is the Building Code (BauGB), particularly paragraphs 127 to 135. These regulations authorize municipalities to apportion a significant part of the costs to property owners. The municipality can pass on up to 90% of the costs for technical and traffic-related development to you as the owner. The remaining 10% is borne by the municipality since the infrastructure also serves the public. The exact distribution keys and calculation bases are specified in the respective municipal development contribution statute. Therefore, it is crucial to review this statute early at the responsible building authority. A look at the land value map can also provide insight: The abbreviation “ebf” stands for “development contribution-free,” while “ebp” indicates an area subject to development contributions. A sound assessment of building law protects you from unexpected demands.
Accurately calculate the development contribution
The calculation of the individual development contribution is often opaque for laypeople. The municipality distributes the allocable total costs of a development area among the individual plots. The distribution criteria usually include the plot size and the buildable usability. Two key figures from the development plan are central for this: the site coverage ratio (GRZ) and the floor area ratio (GFZ). The GRZ indicates what percentage of the plot area can be built over, while the GFZ defines the maximum permissible floor area. A plot that allows for higher building use (e.g., due to a higher GFZ) is generally burdened with a higher contribution. An example: with costs of €40/m² and a plot of 500 m², alone €20,000 may be incurred. To know such costs precisely in advance, you can use our ImmoGPT-Chat, which helps you interpret the relevant key figures for your plot analysis.
Strategies for cost optimisation in land development
Although many costs are fixed, there are still levers to save your budget. A proactive approach can reduce the financial burden by 10-15%. Here are some tried and tested strategies:
Check land status: Clarify the development status before purchase. A plot marked as "no development contribution" (ebf) is often the better choice, even if the purchase price seems higher.
Analyse municipal by-laws: Request the development contribution by-law from your municipality. Understand the distribution key and the estimated costs.
Compare offers for house connections: For the private development on your property, you can inquire with various civil engineering companies and suppliers, potentially saving several hundred euros.
Opt out of unnecessary connections: Do you really need a gas connection if you are heating with a heat pump? Opting out can save up to €2,000.
Check for grants: In some cases, there are regional funding programmes, for example, for connecting to a district heating network.
These measures help you consider the key points when buying land and avoid cost traps.
The value contribution of development for your property
The costs of development for new builds are not wasted expenses, but a direct investment in your property's value. A fully developed plot is a prerequisite for obtaining planning permission and forms the basis for any construction project. Secure connections to infrastructure significantly increase a plot's market value—often by more than just the pure development costs. A professional evaluation of the infrastructure and the plot by Auctoa precisely quantifies this increase in value. A well-located, developed plot can experience a value increase of over 25%. Our AI-supported analysis considers the degree of development and provides you with a data-driven foundation for sales or financing decisions. This way, you not only understand the costs but also the value enhancement potential of your plot.

Development in a new build is far more than just a necessary cost factor. It is a strategic decision that determines the success and economic viability of your entire project. A thorough understanding of the costs involved, the legal foundations according to the Building Code, and the local statutes protects you from unwelcome surprises. Through proactive planning and exploring potential savings, you can actively manage the financial burden. Consider development as the first value-adding measure for your property. An informed, data-driven assessment helps you make every decision with confidence.

FAQ
What is the difference between public and private development?
Public development includes all measures up to your property boundary and is organised by the municipality. Private development (house connections) concerns all lines on your property from the boundary to the building and is your responsibility.
How long does the municipality have to demand the development contribution?
The local authority has four years to issue the assessment notice after the completion of the development measures. However, in practice, this usually happens much more quickly.
Can I deduct the development costs from tax?
Development costs for a privately used new building can generally not be claimed for tax purposes. It is different for rented properties, where they can be written off as part of the production costs over the useful life.
What does 'erschließungsbeitragsfrei' (ebf) mean?
The abbreviation 'ebf' in the standard land value or purchase contract means that no further development contributions are due for the property, as these have already been paid. This is an important indicator for cost planning.
How can Auctoa help me with development costs?
Auctoa offers an AI-supported property valuation that precisely analyses the level of development and its impact on market value. With our ImmoGPT, you can also quickly and easily resolve questions concerning specific aspects like the GFZ or GRZ, thus securing your cost planning.
Are the costs for surveying the property part of the development costs?
The costs for the official survey of the property are considered part of the ancillary building costs, but they are generally viewed separately from the municipality's development contributions. Depending on the effort involved, they can range from 500 to 2,500 euros.
