Connection fees

Connection Fees - Connection fees (also known as installation fees or connection charges) are one-time costs incurred when a property is connected to public infrastructure for the first time-specifically to the drinking water supply, wastewater disposal, and electricity, gas, and telecommunications networks. They are charged by the respective utility companies or the municipality.

Typical Costs

Connection fees vary depending on the municipality, type of utility, and property size. In the Nuremberg metropolitan area, typical costs for a single-family home are as follows:

Utility Type	Typical Costs (Nuremberg Metropolitan Area)
Water (connection fee)	2,000 - 5,000 euros
Sewage/sewer	3,000 - 8,000 euros
Electricity (grid connection)	1,500 - 3,000 euros
Gas (if available)	1,500 - 3,000 euros
Telecommunications/Fiber Optics	500 - 1,500 euros
Total approx.	10,000 - 20,000 euros

These amounts are estimates - they can vary significantly depending on the distance to the nearest main line, soil conditions, and the scope of civil engineering work. If there is a long trench route from the property to the public utility line, the actual costs may be significantly higher.

For an existing building that is already connected, no new connection fees are usually charged-unless the connections need to be replaced or expanded (such as when increasing the power capacity of the electrical connection for a heat pump or photovoltaic system, re-laying the house connection during road renovation, or retrofitting fiber optics).

Distinction from Ongoing Usage Fees

Connection fees must be distinguished from ongoing usage fees. The connection fee is a one-time payment for the construction of the infrastructure, while the ongoing usage fee is charged for actual consumption (cubic meters of water, kilowatt-hours of electricity). Both cost items must be taken into account in the overall calculation for a new building.

Tax Treatment

Connection fees for initial development are considered part of the acquisition costs of the property and are not immediately tax-deductible. For rental properties, they increase the depreciation base-but only to the extent that they are attributable to the building and not to the land. Connection fees for the renewal of existing connections may be deductible as maintenance expenses and thus as income-related expenses when the property is rented out.

Connection Fees vs. Ongoing Usage Fees - Cost Overview

Cost Type	Nature	Due Date	Tax Treatment
Water connection fee	One-time, public law	Upon connection	Land acquisition costs
Sewer connection fee	One-time, public law	Upon connection	Land acquisition costs
House connection for electricity (grid connection)	One-time, private law	Upon connection	Construction costs of the building (depreciation)
House connection for gas	One-time, private law	Upon connection	Construction costs of the building (depreciation)
Fiber-optic house connection	One-time, private law	Upon connection	Construction costs (depreciation)
Drinking water fee	Recurring, consumption-based	Monthly/annual	Operating costs / Tax-deductible expenses
Sewage fee (wastewater)	Recurring, consumption-based	Monthly/annual	Operating costs / Tax-deductible expenses
Basic electricity fee	Recurring, usage-based	Monthly	Operating costs / Tax-deductible expenses

For new construction lots in development areas, total connection fees can range from 15,000 to 25,000 euros-depending on the location of the main lines and civil engineering costs. These costs must be fully incorporated into the construction cost planning and are financed by banks as part of the overall project.

Funding Opportunities

In some municipalities and through KfW Bank, there are funding programs for specific connections-in particular for:

• Fiber-optic home connections as part of the federal funding program for broadband expansion
• Charging infrastructure for electric vehicles (KfW Grant 442)
• Photovoltaic systems and battery storage with a subsequent increased electricity connection

These funding opportunities should be explored before planning begins, as applications often must be submitted before construction starts.

Practical Tip for Homeowners in Nuremberg

We recommend inquiring about connection fees early on with the relevant utilities and the municipality and including them in the overall cost calculation for the construction project. In Nuremberg, Stadtwerke N-Ergie (electricity, gas), NüWa (water), and Stadtentwässerung Nürnberg are the main points of contact. These costs are often underestimated and can significantly increase financing requirements. Timing is also important: Connection requests should be submitted well in advance, as processing times can take several weeks.

Frequently Asked Questions

Who pays the connection fees-the buyer or the seller?

For new construction, the builder (usually the buyer) pays the connection fees-they are part of the total construction costs. For existing properties, the connections are usually already in place and were paid for by the previous owner during the original construction. The purchase agreement should specify whether any outstanding or overdue development fees are to be borne by the seller or the buyer-hidden costs can lurk here.

Can I finance the connection fees?

Yes, the connection fees can be financed through the construction loan, provided they are included in the total cost breakdown. The bank considers them part of the construction or incidental purchase costs. Important: The costs must be documented-through official notices or binding offers from the utility providers.

Do I have to connect my property to all utility networks?

For water and sewage, there is generally a mandatory connection and usage requirement under municipal regulations. Electricity is effectively indispensable, even if self-supply via PV is theoretically possible. Gas and telecommunications are optional-those who heat with a heat pump and forgo gas heating save on the gas connection fee. Fiber optics are increasingly considered standard for new construction in Bavaria, but are not formally mandatory.

What special considerations apply to connection fees for properties in rural areas within the Nuremberg metropolitan region?

Properties in rural areas (pursuant to Section 35 of the German Building Code) or in scattered settlements outside of development zones often lack a complete public utility infrastructure. Developing these properties with sewer and water connections can incur significant costs if pipes must be laid over long distances. In such cases, development costs can quickly reach five figures-in some instances, the costs are so high that a decentralized solution (small-scale sewage treatment plant, rainwater harvesting) makes more economic sense. In the rural communities around Nuremberg-such as in the Nürnberger Land district or the Neumarkt i.d.OPf. district-builders and buyers should clarify before purchasing a property whether all necessary connections are already in place or secured through public development measures. Although undeveloped properties are offered at lower prices, the development costs can make them significantly more expensive than a property that is already developed, even if the purchase price is higher.
