Housing Promotion

Concept and Legal Foundations of Housing Promotion

Die Housing Promotion encompasses all state and public-law measures to support and create adequate, socially acceptable, and sustainable housing. The aim of housing promotion is to provide affordable housing for broad segments of the population, to stabilize the housing market, and in particular, to support economically disadvantaged and vulnerable groups in the housing sector. The legal framework for housing promotion is primarily derived from the Basic Law, specific federal and state laws, as well as subordinate regulations and funding guidelines.

Constitutional Foundations

The fundamental rights, especially Article 14 (guarantee of property) and Article 20 (the social state principle) of the Basic Law (GG), form the foundation of public housing promotion. Article 6 GG further emphasizes the protection of marriage and family, which may justify increased support for families with children. The social state principle obligates the state to take measures to ensure social justice – which includes the provision of housing.

Statutory Regulations

Housing Promotion Act (WoFG)

The Housing Promotion Act (WoFG) forms the federal guideline for social housing promotion. The Act comprehensively regulates:

  • target group funding,
  • the funded activities (e.g., new construction, modernization, renovation),
  • the design of funding benefits (e.g., loans, grants, guarantees),
  • Rights and Obligations of Beneficiaries

The implementation and detailed structuring are the responsibility of the federal states in the federal system, which act through their own state housing promotion laws and funding guidelines.

State Law Regulations

The federal states have enacted their own legal provisions on housing promotion. These implement the WoFG and adapt the funding content to regional needs and housing situations. In addition to state-specific housing promotion laws, specific funding guidelines are issued that regulate the type, scope, and eligibility criteria for support.

German Building Code (BauGB)

The BauGB influences housing promotion in particular through urban development measures, redevelopment and development areas, as well as special regulations regarding land provision. Municipal statutes based on the BauGB can contribute to creating or securing subsidized housing (e.g., through the so-called ‘development plan with social objectives’).

Types and Instruments of Housing Promotion

Promotion of Social Housing Construction

Social housing promotion is the core area of state support for housing. The target groups are, in particular:

  • Households with low to medium incomes
  • Families, single parents, people with disabilities
  • Elderly people as well as special needs groups

The main instruments of support are:

  • Provision of low-interest loans
  • Grants which are not subject to repayment
  • Individual and object-based subsidies (direct support for users or housing providers)
  • Provision of building land under preferential conditions

Modernization and Renovation Funding

Modernization and renovation measures are also supported within the framework of housing promotion. The aim of the funding is to sustainably secure the housing stock, carry out energy-efficient refurbishments, and create age-appropriate or barrier-free housing.

Support for Specific Target Groups

For households with special needs, there are additional areas of support, for example for refugees, students, persons with disabilities, or people in precarious housing conditions. The funding conditions can be tailored individually (e.g., higher grants, extended obligation periods).

Requirements and Allocation Procedure

Income Limits and Eligibility for Housing

A key requirement for accessing social housing funding is compliance with certain income limits, which are updated regularly and are based on average income structures. Proof is provided by the issuance of a certificate of eligibility (Wohnberechtigungsschein, WBS), which permits renting publicly subsidized housing.

Restrictions and Purpose Requirements

Within the framework of housing promotion, certain occupancy and rent restrictions are imposed on subsidized apartments. The purpose requirement stipulates that these apartments may only be let to eligible tenants at set rental prices. The binding periods range depending on the funding model from ten to over thirty years.

Application Procedure and Approval Authorities

Eligible applicants include natural persons, developers, charitable organizations, and housing companies. Applications are submitted to the competent approval authorities – usually state or city administrations or specialized funding banks – and are processed according to the legally regulated administrative procedure.

Legal Consequences and Oversight

In cases of misuse of funding or improper use of subsidized housing, there is a risk of reclaiming the funds, imposition of fines, or further regulatory measures. To monitor compliance, regular audits and inspections are conducted by the responsible authorities.

European and Tax Law Aspects

Integration into European Legal Requirements

Housing promotion is carried out in accordance with European state aid law. Funding programs must be designed so as not to result in unlawful market distortion. The European Commission has issued guidelines on state aid in the housing sector.

Tax Aspects

Support benefits may have tax implications for recipients. This may concern, for example, the treatment of grants as taxable income or the deduction of expenditure related to the funding in accordance with the Income Tax Act (EStG). The tax treatment varies according to the specific structuring of the measures.

Current Developments and Reforms

Housing policy challenges such as housing shortages, demographic change, and energy efficiency requirements for buildings require continuous adjustments to statutory and funding regulations. The current focus is, in particular, on increasing the available funding, expanding the target groups, greater consideration of ecological standards, and the digitalization of funding procedures.


Summary: Housing promotion in Germany is underpinned by a complex interplay of federal and state regulations. Its aim is to create affordable and needs-oriented housing for broad sections of the population. Key statutes include the Housing Promotion Act, state-specific provisions, the German Building Code, and European regulations. The support is subject to specific requirements, obligations, and verification duties, and constitutes a central element of social welfare provision.

Frequently Asked Questions

Who is eligible to apply for housing promotion according to the current legal framework?

In principle, eligible for public housing promotion are natural persons who wish to build, acquire, modernize, or renovate housing for their own use or for others and who, according to the relevant funding provisions or guidelines, are deemed eligible. The precise eligibility is determined in particular on the basis of the legal requirements of the Housing Promotion Act (WoFG) and of the specific funding programs at the state and municipal levels. As a rule, determining factors include the personal and economic circumstances of the applicant, in particular that the total income does not exceed the legally defined limits. In addition, eligibility may be linked to other legal requirements, such as permanent primary residence, compliance with certain dwelling sizes, or adherence to special social or demographic criteria. Legal eligibility also extends to legal entities, provided they act as developers in social housing and properly submit the required documentation and funding applications.

What legal evidence and documents are required for the application?

Depending on the funding program and legal basis, various documents must be submitted as part of the application for housing promotion, most of which are stipulated by law or further specified in funding notices or administrative regulations. As a rule, a written application stating all relevant personal and financial details is mandatory. Further, current proof of income for all household members, if applicable proof of assets, proof of land ownership (e.g., land register excerpt), construction or purchase contracts, proof of compliance with specified dwelling sizes, and if necessary, energy certificates, must be submitted. Legal entities must additionally present proof of representation and, if required, documentation of charitable or other social objectives. The required documents are determined by the administrative regulations of the respective funding agency and are regulated in detail in § 6 WoFG and the corresponding state implementation laws.

What legal obligations arise from receiving housing subsidy funds?

By accepting housing subsidy funds, the recipient incurs extensive legal obligations. Firstly, the subsidized housing is subject for the duration of the obligation period to the social restrictions stipulated in the funding decision and the underlying statutes. These include in particular rental price caps according to fixed maximum limits, occupancy restrictions—meaning allocation only to specific groups of persons—and the intended use of the property (e.g., use as a primary residence). Furthermore, there is a comprehensive duty to notify the granting authority about all significant changes, such as ownership transfers or changes in use. If these legal obligations are violated, there is a risk that the subsidy funds must be repaid and even compensation for damages may be demanded. The main points of reference are the provisions in the approval notice, the WoFG and supplementary state regulations.

How long do binding periods in housing promotion last and under what conditions?

The binding periods for housing promotion are regulated by law or in the approval notice and concern the duration for which the subsidized housing is subject to certain legal requirements, in particular rent and occupancy restrictions. According to § 88 WoFG, for newly created subsidized dwellings, binding periods are generally set between 15 and 30 years, unless different arrangements are specified by state law or in the funding decision. During this time, the apartments may only be rented out to specific, eligible households at capped rents. Early release from the binding obligation is only possible under narrow legal conditions and generally in exchange for repayment of the funds or a settlement payment. After the end of the binding period, the dwelling re-enters the open housing market, provided no further obligations exist.

What legal risks arise from violating funding requirements?

A violation of the legal requirements and funding conditions as defined in the approval notice and relevant laws can have serious legal consequences. The most common risks are the partial or complete revocation of the subsidy, the reclaiming of already disbursed grants or loans—including any applicable interest and surcharges. In addition, fines may be imposed under the applicable state or federal laws. Depending on the severity and nature of the violation—such as unauthorized change of use, misappropriation, letting to non-eligible persons, or exceeding the permissible rent—even criminal consequences may arise, for example under § 263 StGB (fraud), if deception can be proven. Even unintentional breaches may result in fines if negligence is demonstrably attributed to the subsidy recipient.

What is the legal procedure when transferring ownership of subsidized housing?

In the case of a transfer of ownership (sale, gift, inheritance) of subsidized housing, there is a statutory obligation to notify the competent funding authority. The legal obligations relating to the funding—especially restrictions on rent, occupancy, and use—generally remain in place and are transferred to the successor in title, provided the obligation period is still running. As part of the ownership transfer, the purchaser is usually required to give written consent to the existing funding obligations; this can be done by submitting a declaration of commitment or by its inclusion in the notarized purchase agreement. If such consent is not obtained, the funding authority may continue to enforce obligations against the original subsidy recipient or may even demand early repayment of the funds. Details are regulated in the WoFG, the relevant state laws, and often in the loan or funding contracts.
