Building Code (BauGB)

If your property is located in a social conservation area, you will need to apply for a permit for certain construction or renovation work. Here you'll find information on the process, costs, duration, and required documents.

Modernizations, the conversion of rental apartments into condominiums, and the sale of entire buildings can lead to long-standing residents being displaced or no longer being able to afford rising rents. Social preservation ordinances are intended to counteract this by defining social preservation areas in which major renovations are limited and speculative sales are made more difficult.

If you own a property located in a social conservation area, you may need a permit for certain projects. While some construction projects generally require a permit, stricter requirements may apply in social conservation areas.

You must apply for a permit for the following projects within a social conservation area:

• Demolition of buildings or parts of buildings,
• Construction or modernization measures that could increase the value of the property and result in rent increases (e.g. installation of balconies or elevators, extensive changes to the floor plan, extension through attic conversions).
• Changes in the type of use (e.g. conversion of rental apartments into office space or condominiums)

If you sell a building in a Social Conservation Area, the right of first refusal can be used to protect the social fabric. The new owner will be examined to determine whether he has any speculative intentions, such as conversions or rent increases. If concerns arise, the responsible authority can purchase the building itself to ensure its preservation.

Which documents you need to submit depends on the nature of your request. Contact the relevant office to find out the exact requirements in your specific case.

• Your modernization project aims to provide contemporary furnishings in an apartment typical of the area.
• Your project does not pose any risk of a change in the resident structure.
• You do not act with speculative intent, which would result in disadvantages for your tenants.

Depending on the nature of your request and the circumstances of the individual case, further or different requirements may apply.

The costs involved depend on the nature of your request. Please contact the relevant office to find out the exact costs in your specific case.

• You submit your application along with the necessary documents to the responsible authority.
• The competent authority will examine your application and, in particular, whether the measures you intend to take are likely to have adverse effects on the composition of the population.
• The responsible authority will decide on your application and inform you of the decision in writing.

The processing time depends on the nature of your request. Please contact the relevant office to find out the exact requirements in your individual case.

The deadlines that apply depend on the nature of your request. Please contact the relevant authority to find out the exact requirements in your specific case.

The Social Preservation Ordinance has no impact on general rent increases that are not related to construction work.
