Developed Plot: Fully or Partly Developed?
"Fully developed" sounds reassuring but is used inconsistently. This guide explains the difference between fully and partly developed. It lists what belongs to development and quantifies the cost ranges for 2026. That way you buy a plot without expensive surprises.
“Fully serviced” sounds reassuring – yet the term is used inconsistently and can decide over thousands of euros in additional costs. Is a plot really ready to build on, or are the house connections still missing? This guide explains the difference between fully and partly serviced plots, lists what the servicing (Erschließung) includes, and puts figures on the cost ranges for 2026.
Short answer: A serviced plot (erschlossenes Grundstück) is connected to the road, water, sewage, electricity and telecommunications. Fully serviced means the house connections reach right onto the plot; partly serviced means only the public mains run in the street and the connections are still missing. As a rough guide, servicing often costs between €10,000 and €25,000 per single-family home plot in 2026.
What exactly does “serviced plot” mean?
Short answer: A plot is serviced when it is connected to the public supply and transport network. Technically, a distinction is made between public (external) servicing up to the plot boundary – road, footpath and mains – and private (internal) servicing, i.e. the house connections from the transfer point into the building. Only when both levels are in place is a plot genuinely connected and ready to build on.
The term “serviced” is not a protected standard – sellers use it in different ways. Always ask specifically which connections have already been installed and paid for. How to assess a plot overall is shown in the guide Finding and assessing a plot.
What is the difference between fully and partly serviced?
Short answer: Fully serviced means all house connections are brought right onto the plot and usually already paid for – you only need to have them connected. Partly serviced means that while the public mains run in the street, the spur lines and connections onto the plot are still missing and have to be commissioned and financed by you. Undeveloped prospective building land (Bauerwartungsland) is not connected at all yet.
Servicing levels compared
| Level | What is in place | What is still missing / due |
|---|---|---|
| Fully serviced | house connections onto the plot | just have them connected |
| Partly serviced | mains in the street | spur lines & house connections |
| Unserviced | land with no connection | full servicing required |
A low purchase price for a partly or unserviced plot quickly loses its appeal once the servicing has to be added afterwards. The individual cost blocks are broken down in detail in the guide Servicing a plot.

What all is included in servicing?
Short answer: Servicing includes the transport connection via a passable road with footpath and lighting, as well as supply and disposal: drinking water, sewage (mains sewer), electricity and telecommunications. Where needed, gas or district heating is added. Besides the technical connection, the legal servicing matters too – for example a secured access route, without which no building permit (Baugenehmigung) is granted.
- Road, footpath and lighting as the transport connection.
- Drinking-water connection from the utility into the house.
- Sewage connection to the public sewer or an approved small treatment plant.
- Electricity connection and meter position with the right capacity.
- Telecommunications and ideally a fibre-optic connection.
- Legally secured access, especially for rear plots.
Don't forget the legal servicing
A plot set back from the road needs a right of way and utilities registered in the land register (Grundbuch) across the front plot – otherwise the building permit can fail on the missing servicing, even though all the mains are technically within reach. Clarify this with the notary before buying. How to evaluate a development plan (Bebauungsplan) for this is shown in the guide Reading the development plan.
What does servicing cost in 2026?
Short answer: As a guide value, the total costs in 2026 often lie between €10,000 and €25,000 per single-family home plot, split between municipal servicing contributions (Erschließungsbeiträge) and the private house connections. The exact amount depends on the location, line lengths, ground conditions and municipality. With a fully serviced plot, many of these costs are already included in the purchase price.
Typical cost blocks of servicing (as of 2026, guide values)
| Cost block | Range | Who usually bears it |
|---|---|---|
| Municipal servicing contributions | €5,000–15,000 | residents / buyers |
| Water & sewage connection | €3,000–8,000 | owner-builder |
| Electricity connection | €2,000–4,000 | owner-builder |
| Telecoms / fibre | €500–2,000 | owner-builder |
Factor servicing firmly into your budget before you buy a plot. Current price levels for building land are given in the guide Land prices 2026.
How does servicing proceed and how long does it take?
Short answer: The public servicing is organised by the municipality; you apply for the private house connections individually with the water, electricity and telecommunications providers and have the trenches dug. Depending on how busy the utilities are, allow for several weeks to months of lead time. Coordinate the appointments early so the connections are ready by the start of construction.

Conclusion: ask first, then calculate
“Serviced” is not a blank cheque – before buying, clarify exactly which connections have been installed and paid for and whether the access is legally secured. A fully serviced plot saves time and surprises; a partly serviced one calls for an honest calculation of the additional costs. The total budget including the house price can be worked out in advance with the prefab house cost calculator and put into perspective using the current prefab house prices 2026.
