Spotting a Wohnungsbindungsvertrag in the title: resale limits, rent rules and grant‑clawback risks

What a Wohnungsbindungsvertrag is — legal basis and purpose

A Wohnungsbindungsvertrag (social‑housing covenant or binding agreement) is the contractual or public‑law condition attached to property that arises when public funds are used to create or modernise housing. At federal level the framework for subsidised housing is the Gesetz über die soziale Wohnraumförderung (WoFG); the law requires that a Förderzusage (funding commitment) specify the legal consequences of an ownership change and the form, amount and duration of any rent and allocation (Belegungs‑) bindings. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/wofg/BJNR237610001.html))

The concrete rules — how long a property remains “bound”, who may live there and what rent can be charged — are set out in the Förderzusage and in the applicable state and municipal implementing rules (for example Berlin’s Wohnraumgesetz and the Wohnungsbindungsregeln). If public money is involved, those binding obligations are enforced by the housing authority and can be secured by entries in the land register (Grundbuch). ([berlin.de](https://www.berlin.de/sen/wohnen/rechtliches/sozialer-wohnungsbau/wohnraumgesetz-berlin/?utm_source=openai))

How the covenant typically appears in title paperwork

The common way to secure a Wohnungsbindungsvertrag is a registered encumbrance in the Grundbuch. Municipal contracts and planning agreements routinely require a "beschränkt persönliche Dienstbarkeit" or similar entry labelled as a "Wohnungsbindungsrecht" or "Wohnungsbindung"; the entry may be terse and refer to the notarised contract or the Förderzusage for detail. Practical wording varies, but courts accept even short, descriptive Eintragungsvermerke if the deed is referenced. ([berlin.de](https://www.berlin.de/ba-tempelhof-schoeneberg/_assets/politik-und-verwaltung/aemter/stadtentwicklungsamt/stadtplanung/bebauungsplanung/bebauungsplaene-im-verfahren/b-plan-7-100ve/7-100-ve_3-2_durchfuehrungsvertrag.pdf?ts=1732281006&utm_source=openai))

Notaries and land‑registry practice explain that such servitudes (Dienstbarkeiten) are a standard way to make an obligation enforceable against later purchasers: the Grundbuch shows the limitation and the public authority has a concrete legal ground to act. Always inspect Abteilung II (rights and encumbrances) and Abteilung I (ownership and Vormerkungen) of the Grundbuchauszug. ([notar.de](https://www.notar.de/themen/immobilien/dienstbarkeiten?utm_source=openai))

What those entries mean for a buyer: resale and rent rules

If a dwelling is subject to a Wohnungsbindung, the Förderzusage and the registering instrument will contain (or point to) limits such as: a maximum permitted rent on new lets, the target tenant groups (WBS or income bands), and a binding duration (commonly multiples of years). Municipal programmes for newly funded units often set long binding periods — for example, a Berlin programme shows a 30‑year Mietpreis‑ and Belegungsbindung from first occupancy on funded new builds. ([ibb.de](https://www.ibb.de/de/foerderprogramme/ibb-wohnungsneubaufonds.html?utm_source=openai))

For buyers this typically means: you cannot re‑let at market rent while the Mietpreisbindung runs; you may be restricted to letting to households with a Wohnberechtigungsschein (WBS) or within specified income limits; and you must carry the obligations on resale unless the funding authority expressly releases the property. The WoFG requires that the Förderzusage spell out the “Rechtsfolgen eines Eigentumswechsels”. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/wofg/BJNR237610001.html))

Grant‑clawback and enforcement risks

Public authorities enforce the rules. The WoFG gives the authority powers including administrative enforcement and information rights; it also provides for sanctions such as monthly money‑payments for violations: up to €5 per square metre per month may be levied for certain breaches of the rent or allocation rules. The Förderzusage itself will contain specific remedies — including possible partial or full repayment obligations — and must be reviewed. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/wofg/BJNR237610001.html))

Practical consequence: if you buy without satisfying the authority’s procedural conditions (for example failure to obtain a formal release, failure to notify, or unauthorised letting), you can face fines, loss of subsidy or repayment claims. Where the subsidy was secured by a specific real‑estate right, the authority may require replacement security on substitute property subject to statutory limits.

A short checklist for buyers and advisers

1) Ask the seller and the notary for the complete Förderzusage (funding letter/contract) and any notarised Wohnungsbindungsvertrag; the Grundbuchvermerk will usually reference that deed. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/wofg/BJNR237610001.html))

2) Inspect the Grundbuchauszug: look in Abteilung II for entries labelled "Wohnungsbindung", "Wohnungsbindungsrecht" or a beschränkt persönliche Dienstbarkeit, and in Abteilung I for Vormerkungen or creditor annotations. If the entry is terse, obtain the referenced deed. ([notar.de](https://www.notar.de/themen/immobilien/dienstbarkeiten?utm_source=openai))

3) Read the Förderzusage for: binding duration (years), permitted rents on reletting, eligible tenant groups (WBS or income bands), and explicit remedies on sale or breach (repayment clauses, required notifications). The WoFG obliges inclusion of the effects of an ownership change. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/wofg/BJNR237610001.html))

4) Ask whether the housing authority has issued a formal Freistellungsbescheid (release) or whether an Aufhebung (deletion) of the Grundbucheintrag is pending. No informal assurances substitute for a written release. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/wofg/BJNR237610001.html))

5) Use a German‑qualified notary or a specialised lawyer for title and subsidy due diligence — issues here can carry material repayment and compliance risk. This is not personal legal or tax advice; consult a lawyer or tax adviser for your transaction.
