You must apply for the subsidy at the responsible office (housing subsidy office). You can obtain the application forms from the Housing Promotion Agency or via the portal of the Landeskreditbank Baden-Württemberg - Förderbank (L-Bank). Complete and eligible applications will be forwarded to the L-Bank for further processing.
You can also obtain further information and advice on your specific project from the relevant office. L-Bank will help you on 0800/150-3030 (free of charge from the German landline network or with a German mobile phone network and provider; Mon. - Fri. 8.00 am to 4.30 pm), especially with financing questions.
Please note: As a rule, you may not start the project until you have received written confirmation of funding from L-Bank. A premature start to the project will result in the funding being rejected unless the responsible office agrees.
