Why do you need a change of use?

A change of use is necessary if you want to change the type of use of a building or property that differs from the originally approved use. The reason for this is that the new use places different requirements on the property. This is regulated by the building regulations of the federal states.

When do you need a change of use?

A change of use is required if, for example, you convert an attic, convert a shop into a beauty salon, rent out an apartment via Airbnb, convert a single-family home into a two-family home, convert commercial space into residential space or convert an apartment into a restaurant.

How much does a change of use cost?

The costs for a change of use vary. They depend on the size of the property, the complexity of the project, the owner's design wishes and the planning effort required. The requirements of the building control authority can also influence the costs.

What documents are required for a change of use?

The following documents are required for a change of use:
Complete, clearly legible and dimensioned existing plans (views, floor plans and sections), e.g. from the building permit.
An extract from the property cadastre (cadastral extract or cadastral map).

Requirements for a change of use

Basic requirements:
  • Development plan:
    The development plan must be adhered to to ensure that the use is consistent with the established urban development objectives.
  • State building regulations:
    All relevant provisions of the respective state building regulations must be met.
  • Sound and heat insulation:
    Measures must be taken that comply with the applicable standards for sound and thermal insulation.
  • Development:
    The development of the property, including the supply of water, electricity and sewage disposal, must be secured.
Requirements for a change of use requiring approval:
  • Approval by the authority:
    A formal permit must be applied for and approved by the responsible building authority.
  • Hiring an architect:
    An architect or draftsman authorized to submit building plans must be commissioned to prepare the necessary plans and documentation.

Important factors in a change of use

  • Fire protection:
    Escape routes, emergency exits, fire brigade setup areas – every project must meet fire protection requirements.
  • Pitches:
    The state building regulations require a certain number of car and bicycle parking spaces for each use, which must be proven.
  • Accessibility:
    Disabled toilets, barrier-free entrances, door widths – the state building regulations require every building to be barrier-free. In exceptional cases, an exemption can be granted.

Consequences of an unauthorized change of use

If the requirements are not met, especially if the required building permit is missing, this can have unpleasant consequences. In the worst case, the use can be prohibited by the responsible authority. Use may only be resumed once all discrepancies have been resolved. Subsequently required structural changes can incur additional costs. Anyone who begins a new use without the required change of use permit must also expect to be fined.
