Repurposing: which spaces are suitable?
A change of use refers to a situation in which property owners intend to use a building or structure differently in the future than originally stipulated in the zoning plan. This may become necessary when the owner’s needs or the requirements for the use change. One common example is the conversion of a department store into an office building. Under certain conditions, residential use may also be an option. In times when housing is scarce and large department stores are closing, the topic of change of use is therefore becoming increasingly relevant for property owners. But what does it actually involve when changing the designated use of a building? We explain which spaces are suitable for repurposing, which legal requirements apply, and how much such a measure can cost.
From industrial to residential, from residential to commercial
The most common types of repurposing include converting commercial or industrial spaces into residential units; transforming barns or garages into living space; and converting residential space into commercial premises. Converting commercial or industrial areas into residences is particularly relevant in larger cities to help meet the demand for housing in central locations. In rural areas, converting barns or garages into living space can make a property more attractive, for example.
Building regulations for a change of use
To carry out a change of use, approval from the building authority is generally required. However, the exact regulations and requirements may vary depending on the federal state and municipality. In many cases, a building permit application is necessary, which must be submitted by an architecture or engineering firm. The plans and construction descriptions must meet the requirements of the respective building authority and must take into account regulations such as fire protection, noise control, and energy efficiency.
In some cases, exceptions to the approval requirement may apply—for example, when the change of use is minor or when it has no impact on the structural integrity of the building. An example would be converting a basement room into a hobby room or turning an attic into an additional bedroom. In such cases, it must still be verified whether a preliminary building inquiry is required or whether the change of use can be implemented without additional permits.
It is important for property owners to thoroughly inform themselves in advance about applicable legal requirements and, if necessary, seek advice from a specialized law firm or engineering office. This is the only way to ensure that the change of use is implemented lawfully and that no legal conflicts arise later.
What costs should be expected?
The costs of a change of use can vary greatly depending on the type of repurposing and the scope of the required work. Property owners generally need to factor in additional costs for planning, permits, construction work, and possibly also for adjustments to utility systems. It is therefore advisable to conduct a detailed cost calculation in advance and to review potential financing or subsidy options. Carefully selecting skilled tradespeople and construction companies can also help keep costs under control.
