Federal Clean Air Act

Federal Immission Control Act - The Federal Immission Control Act (BImSchG) protects people, animals, plants, and property from harmful environmental impacts-in particular from noise, air pollution, vibrations, and odors. In the real estate sector, the BImSchG is relevant for the approval of emission-generating facilities in the neighborhood, noise protection against traffic emissions, and the assessment of location qualities.

Relevance for Property Owners

The BImSchG affects property owners in several areas:

• Noise Protection: The TA Lärm (Technical Instructions on Noise Protection) establishes emission guidelines that must not be exceeded in residential, mixed-use, and commercial areas. In purely residential areas, the limits are 50 dB(A) during the day and 35 dB(A) at night.
• Traffic Noise: The Traffic Noise Protection Ordinance regulates protection against road and rail traffic noise. Owners of properties on heavily trafficked roads may be entitled to passive noise protection (soundproof windows).
• Facilities Requiring Permits: Industrial and commercial facilities (factories, biogas plants, livestock farms) in the neighborhood require a BImSchG permit to ensure the protection of residents.
• Odor Emissions: The GIRL (Odor Emission Guideline) regulates what level of odor pollution is acceptable in different types of areas.

Significance for Real Estate Valuation

Environmental pollution has a direct impact on property value: Noise pollution from roads, railways, or commercial activities results in value reductions of 5-20% compared to quiet locations. In real estate valuation, emissions are considered a specific property-related characteristic. Proximity to facilities requiring permits can also reduce value-even if emission limits are met.

For prospective buyers, understanding the BImSchG-relevant environment is a key component of location analysis. Whether a nearby industrial facility complies with emission limits can be verified through the BImSchG approval file at the relevant authority (in Bavaria: Regional Council or District Office). The approval file is publicly accessible and contains the permissible emission values as well as any imposed conditions.

Noise Maps and the Environmental Noise Directive

The EU Environmental Noise Directive requires municipalities above a certain size to create noise maps and noise action plans. The City of Nuremberg publishes these maps online and updates them regularly. Prospective buyers and property owners can use the maps to determine the noise levels at a specific location-in dB(A) values, broken down by road, rail, and aircraft noise. These maps provide a valuable basis for location assessment and can be used in purchase price negotiations.

Noise Exposure Guidelines According to TA Lärm - Overview

Area Type	Daytime (6 a.m.-10 p.m.)	Nighttime (10 p.m.-6 a.m.)	Typical Nuremberg Example
Pure residential area (WR)	50 dB(A)	35 dB(A)	Erlenstegen (quiet residential streets)
General residential area (WA)	55 dB(A)	40 dB(A)	Maxfeld, Gostenhof
Mixed-use area (MI)	60 dB(A)	45 dB(A)	Südstadt, area around the Südwesttangente
Commercial area (GE)	65 dB(A)	50 dB(A)	Port, Schweinau industrial area
Industrial area (GI)	70 dB(A)	70 dB(A)	Heavy industry, no residential use

Practical relevance: Anyone purchasing property along the Frankenschnellweg corridor or the railway ring should commission a noise measurement. Proven exceedance of the guideline values may justify claims for active noise protection or passive sound insulation (soundproof windows).

Practical tip for property owners in Nuremberg and Franconia

We recommend that buyers in the Nuremberg metropolitan area check the noise levels of the location before purchasing-the City of Nuremberg publishes noise maps in accordance with the EU Environmental Noise Directive, which are available online. Locations along the Frankenschnellweg route, the Südwesttangente, or near the airport are particularly affected. For sellers: Demonstrating that noise levels are below the limits or that soundproofing measures have been implemented (new windows, facade insulation) are value-adding points in the property listing. Soundproof windows can not only significantly improve the quality of living but also increase the selling price by several thousand euros.

Frequently Asked Questions

Am I entitled to noise protection on a noisy street?

For new construction or major modifications to a road, the limits set by the Traffic Noise Protection Ordinance apply-if these limits are exceeded, the owner is entitled to active (noise barrier) or passive noise protection (soundproof windows). In cases of existing road noise without structural changes to the road, there is no legal entitlement; however, there are municipal subsidy programs for soundproof windows. In Bavaria, owners can also apply for grants through the federal-state programs for noise protection on federal highways and autobahns.

Can I take action against noise or odors from neighboring properties?

Yes, if the emissions exceed the limits set by the Technical Instructions on Noise (TA Lärm) or the Federal Noise Protection Ordinance (GIRL), you can request an inspection from the competent noise control authority. Under private law, you can assert claims for injunctive relief and damages pursuant to Sections 906 and 1004 of the German Civil Code (BGB) if the nuisance exceeds the level customary in the locality. Proof requires a noise measurement or an expert opinion-the costs are initially borne by the applicant but may be imposed on the party responsible if the claim is successful.

Does the BImSchG affect building permits?

Yes, for facilities requiring a permit (e.g., commercial and industrial operations), BImSchG approval is a prerequisite for operation. For residential buildings near such facilities, the building authority checks whether emission limits are being met. If limits are exceeded, the building permit for the residential building may be denied or subject to conditions (soundproof windows, orientation of the floor plan). Anyone wishing to build near industrial areas or heavily trafficked roads should clarify the noise exposure situation with an expert at an early stage.

How does aircraft noise affect property values in Nuremberg?

Nuremberg Airport is located in the northern part of the city and has a noticeable impact on living comfort under certain approach and departure paths. In the airport’s noise protection zone, as defined by the Aircraft Noise Protection Act (FluglSchG), stricter protection requirements apply; within protection zones A and B, residents are entitled to noise protection measures and compensation. Prospective buyers of real estate in neighborhoods such as Ziegelstein, Boxdorf, or Rückersdorf should carefully assess the noise situation. The airport’s noise protection zone designation plan can be viewed free of charge. Proven noise abatement measures-such as soundproof windows and insulated ventilation systems-can significantly improve living quality and should be highlighted as a positive feature when marketing the property.

BImSchG and Energy-Efficient Renovation

The BImSchG also applies to energy-efficient renovations: New heating systems powered by biomass (wood pellets, wood chips) must comply with the emission limits of the 1st BImSchV (First Federal Immission Control Ordinance). Older solid fuel systems in residential areas must be retrofitted or replaced by specified deadlines. Owners who wish to replace their oil-fired boilers with pellet heating systems should observe the current limits and deadlines and register the system with the relevant authority. In the Nuremberg metropolitan region, this is the respective district office or city administration. We recommend clarifying the emission control requirements well in advance of investing in a new heating system.
