How to estimate the cost of demolishing buildings


To Construction site equipment heard that Property is freely accessible and not equipped with obstacles of any kind.

If you're with your House building want to start and on the building ground If a house is already in place, this building must be demolished beforehand.


In order to be able to demolish a building, you no longer need a permit, you only need to report your project to the building authority. The demolition of smaller buildings up to a size of 300 cbm of enclosed space or walls, posts and masts is even ad-free.

Since you won't be doing the demolition yourself, you have to hire a demolition company. In addition to the qualification for the demolition work, this person must also prove that they have the necessary experience with regard to statics and occupational safety. A further prerequisite is that the demolition company can provide the necessary evidence that it has the necessary experience, facilities and equipment for the demolition of buildings. In many cases, the building contractor intended for your house construction is authorized and qualified to also demolish existing buildings.

There are exceptions to the exemption from the obligation to notify in the area of ​​monument protection. Such buildings require permission from the lower monument protection authority to be demolished. With this permit, the application together with the application for a building permit required for your house construction must be submitted to the building authority.

There are also special features with regard to the demolition process if the property is located in a redevelopment area. In any case, the redevelopment authority must be consulted beforehand and a redevelopment permit obtained. The special requirements for building your house in the case of renovation are explained in more detail in our property purchase guide in the land register section.

Problems can also arise if the building to be demolished is adjacent to another building that is not to be demolished. The damage resulting from the fact that insufficient measures were taken to secure the building that was not demolished during the demolition must then be replaced. A few years ago there was a corresponding ruling by the Frankfurt Higher Regional Court (Az .: 16 U 211/03).

In that case, the homeowner had a semi-detached house demolished in order to start building a new house. Only he had neglected to adequately secure the neighboring house against possible damage from the demolition. On the walls in the neighbour's house, however, severe damage was caused by cracks during the demolition and this caused moisture to form in the wall. The neighbor had to take extensive support and remedial measures.

He therefore asked the house owner to reimburse the costs for the repairs. Rightly so, as the court decided, on the grounds that it is clearly the responsibility of the owner to ensure that adequate security measures are taken when building the house so that damage to the neighboring house can be prevented.

The construction site equipment also requires that the individual parts of the demolished building can be removed or, under certain circumstances, with appropriate sorting of the material, can also be reused.

For the demolition contractor who carries out the demolition work, sorting the components of a demolished house means the most effort. The individual components such as rubble, treated wood, untreated wood, metals, garbage and hazardous waste are separated. Anything that cannot be told apart with the excavator must then be handpicked.

The advantage of sorting is that some of the demolition material can be recycled. In the case of larger quantities, it can be worthwhile to shred the rubble on the construction site. This saves the costs of removal and the broken ballast can be reused on the construction site.
