Hamburg Landlord Required Disclosures: What You Must Provide

Germany's landlord disclosure requirements differ significantly from those in common-law countries. Rather than broad upfront property-condition disclosure forms, German obligations are clustered around registration law, energy transparency, and Hamburg's unique housing protection regime.

1. Landlord Confirmation of Occupancy (Wohnungsgeberbestätigung)

This is Hamburg's — and Germany's — most universally required landlord document, introduced in 2015 to combat fake address registrations (§ 19 Federal Registration Act / BMG).

What it is: A written or electronic confirmation that a named person has actually moved into your property.

When it's due: Within 2 weeks of the tenant's move-in date.

What it must contain:

• Landlord's name and address
• Type of event (move-in)
• Date of move-in
• Full property address (including floor/unit if relevant)
• Full names of all persons moving in

Where to get the form: Hamburg's official template is available at hamburg.de. The tenant needs this document to register their address at the local citizens' office (Einwohnermeldeamt/Kundenzentrum).

Penalties: Willfully withholding or falsifying the document carries fines of up to €50,000.

2. Energy Performance Certificate (Energieausweis)

The Energy Performance Certificate is mandatory under the Buildings Energy Act (GEG) and must be provided at each stage of the letting process:

Two types exist:

• Consumption certificate (Verbrauchsausweis): Based on actual energy use over the past 3 years.
• Demand certificate (Bedarfsausweis): Based on a technical building analysis; required for older buildings with fewer than 5 units built before 1977.

Non-compliance with energy certificate requirements in Hamburg can result in fines of up to €15,000.

3. Hamburg Housing Protection Number (Short-Term Rentals)

Hamburg's Housing Protection Act (HmbWoSchG) bans the commercial short-term letting of residential apartments (e.g., via Airbnb) without authorization. A registration number is required if:

• You wish to rent out your primary residence for up to 56 days per year (you must notify the local Bezirksamt and obtain a number).
• You must display this registration number in all online listings.

Commercial short-term letting beyond personal use thresholds requires a full permit (rarely granted in Hamburg's current policy climate). Violations can trigger fines up to €500,000.

4. Duty to Disclose Hidden Material Defects While Germany has no formal multi-page disclosure form at lease signing, landlords are bound by the principle of good faith (§ 242 BGB). Landlords must proactively disclose material hidden defects they are aware of, such as:

• Structural mold or persistent moisture problems caused by building defects
• Asbestos-containing materials with potential for fiber release
• Pest infestations
• Lack of planning permission for the intended use

Concealing known defects may constitute fraudulent misrepresentation (arglistige Täuschung), entitling the tenant to void the lease and claim damages.
