Private parking enforcement: rights and obligations for operators

Private parking enforcement: these rights and obligations apply to operators

Is a private operator even allowed to issue parking charges? The short answer: yes – the German Federal Court of Justice (BGH) has confirmed private parking enforcement several times. The longer answer: only under clear conditions, and operators who ignore them are left carrying the costs or even risk criminal proceedings.

This guide is aimed at operators of parking areas: supermarkets, hospitals, hotels, local authorities and property managers. It summarises the relevant BGH case law, shows which contractual penalties courts accept, and explains which GDPR obligations apply to licence plate recognition.

The key points at a glance

• Private parking enforcement is legal: clearly visible signage means that parking a vehicle concludes a usage contract (BGH, XII ZR 13/19).
• Contractual penalties of 30 to 50 euros are recognised by the courts. The BGH has expressly approved 20 euros and 30 euros.
• Operators may have unauthorised vehicles towed immediately (BGH, V ZR 144/08), but may only pass on costs at locally standard rates.
• Not recoverable: the cost of parking enforcement itself, together with administration and debt collection fees (BGH, V ZR 30/11).
• Capturing licence plates can be done in a GDPR-compliant way (legitimate interest under Art. 6 (1) (f) GDPR), but requires notice signs before the entrance and a deletion policy.

Is private parking enforcement legal at all?

Yes. The legal construction is a contract, not a fine: anyone who provides a parking area subject to conditions is making what is known as a real-act offer. The driver accepts it by parking their vehicle – with no signature and no conversation. The Federal Court of Justice clarified this in 2019 (judgment of 18 December 2019, XII ZR 13/19).

The parking conditions, including the contractual penalty, become part of that contract as general terms and conditions via the signage. The precondition: the signs are clearly visible and the conditions are clearly worded. If a driver breaches the rules, for example by exceeding the maximum parking time, they additionally commit unlawful interference with possession under § 858 (1) BGB, against which the possessor of the area may defend themselves.

Public parking vs. private land: two entirely different legal worlds

Many discussions about parking enforcement conflate two systems that have nothing to do with each other:

Important for operators: on your own land, no local authority will help. Enforcement rests entirely with the operator, which makes securing evidence and having sound processes all the more important.

The rights operators have

1. Charging a contractual penalty. Courts usually accept 30 to 50 euros as an increased parking charge. The BGH expressly raised no objection to 20 euros (V ZR 160/14) and 30 euros (XII ZR 13/19). The German consumer advice centre (Verbraucherzentrale) considers at least 30 euros permissible.

2. Having vehicles towed immediately. No waiting, no prior notice required: the possessor may have a vehicle parked without authorisation removed by way of self-help (BGH, V ZR 144/08). That applies even if other spaces are free.

3. Identifying the registered keeper. Via a keeper enquiry under § 39 (1) StVG with the vehicle registration authority; the legitimate interest lies in pursuing the claim.

4. Holding the keeper to account. The keeper is not automatically liable for the contractual penalty if a third party was driving. However, if they merely deny in general terms that they were driving, without naming the possible driver, they remain liable (secondary burden of pleading, BGH XII ZR 13/19). In addition, the operator can seek an injunction against the keeper as a disturber of the state of affairs, from the very first violation onwards (BGH, V ZR 160/14).

The obligations and limits that apply

Signage that holds up in court. Case law and the consumer advice centres require: signs at every entrance, clearly legible, with complete conditions (maximum parking time, parking disc requirement, customer-only use, amount of the contractual penalty, note on towing). Hidden signs, or conditions displayed only inside the shop, mean no contract is concluded – which removes the entire basis for any claim.

Passing on only locally standard costs. Towing is subject to the principle of economic efficiency: the BGH objected to a flat fee of 250 euros net and requires local standard costs as the benchmark (V ZR 229/13). Storage fees after towing are recoverable only up to the point at which the keeper requests the vehicle back. In a 2023 case, only 75 euros were awarded instead of the 4,935 euros claimed (V ZR 192/22).

These costs stay with the operator. The cost of parking enforcement itself – patrols and staff – is not recoverable damage. Administration and debt collection costs cannot be passed on to the offending driver either (BGH, V ZR 30/11). Commercially this is the decisive point: manual enforcement is a pure cost block that no offender reimburses.

No wheel clamps. Immobilising someone else's vehicle is predominantly regarded as unlawful and can be criminal as coercion or attempted extortion. Hands off.

GDPR: what applies to licence plate capture

Barrier-free systems capture licence plates by camera. This is permissible under data protection law: the supervisory authorities (including LDI NRW and the Saxon Data Protection Commissioner) base the processing on the operator's legitimate interest in organising and enforcing the parking rules (Art. 6 (1) (f) GDPR), and for registered long-term parkers on the contract (Art. 6 (1) (b) GDPR).

The corresponding obligations:

• Transparency before the entrance: place notice signs so that drivers can still turn around, with all the mandatory information required by Art. 13 GDPR (controller, purpose, legal basis, retention period, data subject rights). The German Data Protection Conference recommends a dedicated symbol for licence plate capture.
• Data minimisation: capture only the licence plate, not people. LDI NRW recommends automatic pixelation.
• Deletion policy: licence plates from compliant parking transactions must be deleted once the transaction is complete. In the event of a violation, data may be retained until the claim has been enforced; the operator must be able to demonstrate that this is necessary.

Our page on licence plate recognition sets out in detail how modern systems implement these requirements technically.

The most important rulings at a glance

Enforcement service provider or digital management in-house?

The classic model is for operators to lease their site to an enforcement service provider, which works with patrols and parking charge notices and keeps the contractual penalties. That costs the operator little, but also brings them nothing beyond a disciplining effect – and, as shown, enforcement costs cannot be passed on.

The alternative is digital parking management: licence plate recognition at the entrance and exit documents every parking transaction automatically and without gaps. That meets precisely the evidentiary requirements the BGH sets for enforcement, makes patrols unnecessary, and turns the site from a cost factor into a source of revenue. What this means for a specific site can be calculated in a few minutes with our savings calculator.

Frequently asked questions about private parking enforcement

Is private parking enforcement legal? Yes. For years the BGH has confirmed that signage plus the act of parking concludes a valid usage contract (most recently XII ZR 13/19).

Is a parking charge notice from a private enforcement company lawful? In principle yes, provided the signage was clearly visible and the contractual penalty is reasonable (typically 30 to 50 euros). In legal terms it is not a regulatory fine but a civil law claim.

Can the local authority issue parking tickets on private car parks? No. The StVO generally does not apply on private land, and the local authority and police are usually not responsible there. Enforcement is the operator's job.

Is the keeper or the driver liable? The contracting party is the driver. In practice, however, the keeper is liable as well if they do not name the person who was driving (secondary burden of pleading, BGH XII ZR 13/19).

How does digital parking enforcement work? Cameras capture the licence plate on entry and exit, parking duration is calculated automatically and matched against payments or permissions. Patrols and barriers are no longer needed.

Conclusion: use the rights, automate the obligations

The legal position favours operators: contractual penalties, immediate towing and keeper liability via the secondary burden of pleading provide effective tools. The limits lie in proportionality, in the enforcement costs that cannot be passed on, and in GDPR obligations. Those three points are exactly the case for automation: a digital system documents everything in a legally sound way, works in a GDPR-compliant manner with a deletion policy, and removes the largest non-recoverable cost block – manual enforcement – entirely.
