You can apply for the certificate in writing as the owner of a building or as an authorised representative/representative of the owner. Since the certificate is issued on an object-related basis, you must apply for an individual certificate for parts of buildings that are independent immovable assets (e.g. underground car park), as well as for condominiums and partially owned rooms. In the case of developer or buyer models and residential and part-ownership communities, you can instead apply for an overall certificate including the distribution to the individual parts of the building. For this, you need the effective powers of attorney of the purchasers.

The competent certifying authority shall then verify:

• whether the building is located in a formally defined redevelopment area or urban development area,
• whether modernisation and repair measures or other measures have been carried out for the preservation, renewal and proper use of a building which is to be preserved because of its historical, artistic or urban importance,
• the amount of costs incurred for the certifiable measures, and
• whether and to what extent subsidies from public funds have been approved by an authority responsible for redevelopment areas or urban development areas or will be granted after the certificate has been issued.

In order to give you clarity about the content of the expected certificate at an early stage, the certifying authority can already give you a written assurance about the expected certificate. However, the assurance does not replace the certificate. It is therefore not suitable as proof when applying for tax benefits at the tax office.
In the case of a legitimate interest, however, you can apply to the tax office for binding information on the expected basis of assessment of the tax benefits subject to a fee.
