Can my landlord raise the rent whenever he likes?
He can announce it any time — but it only takes effect from the next possible termination date. The landlord must notify the increase at least 14 days before the notice period begins, in writing and with reasons; otherwise it is void (§ 1090 Art. 59 ABGB). Here is the myth, and it is the whole point of this page: "Liechtenstein works like Switzerland — I will get an official form and I can go to the conciliation board for free." Neither exists here. The official-form requirement was deliberately abolished in the 2017 tenancy reform, and there is no conciliation board for tenancy matters at all: the mediation offices were shut down on 1 July 2015. "Challenging" an increase means filing suit at the Landgericht, within four weeks.
📋 The rules
- § 1090 Art. 59(1) ABGB: the landlord may raise the rent at any time with effect from the next possible termination date — and he must notify the tenant at least 14 days before the notice period starts, in writing, giving reasons. Notice period for residential property: 3 months to month-end (Art. 39); commercial premises 6 months (Art. 40).
- Void on a formal defect (Art. 59(3)): the increase is void if the notice lacks the minimum content — the date and the reasons — or if the landlord couples it with a threat of termination or an actual termination.
- The substantive limit (Art. 55(2)): an increase is unlawful if it produces an "unreasonable return". Unlike a challenge to the initial rent, this does not require you to show hardship or a dominant market position on the landlord's side.
- What stays lawful (Art. 56): there is no unreasonable return where the rent is customary for the locality or district, is justified by cost increases or added services, stays within the cost-covering gross yield on newer buildings, or merely preserves purchasing power.
- Challenge: 4 weeks, and it goes to court (Art. 62). The tenant must challenge the increase within four weeks of the notice before the Landgericht — miss it and the claim is forfeited. While proceedings run, the existing contract continues unchanged (Art. 65).
🔓 Exceptions
- Luxury property drops out entirely (Art. 3(2)): rent protection does not apply to flats over 150 m² of net living space or detached houses over 200 m². In that segment there is effectively no control over increases at all.
- Index-linked rent (Art. 57): where the rent is tied to an index, the increase can only be challenged to the extent it does not track the national consumer price index. An index-conforming rise is not attackable.
- Stepped rent (Art. 58): permitted only on a lease of at least 3 years, with no more than one increase per year and the amount fixed in francs. Stepped rents as such are not challengeable (Art. 64).
⚠️ Penalties & fines
A formal defect costs the landlord the increase: it is void, and you keep paying the old rent. The more expensive mistake, though, is the tenant's. Let the four-week window lapse and your right to challenge is forfeited — the inflated rent then stands permanently, even if it was objectively unlawful. And because Liechtenstein has no conciliation board for tenancy disputes, "challenging" means proceedings at the Princely Landgericht, with court and lawyer costs instead of a free conciliation hearing. That barrier is real, and it is why many unlawful increases are never challenged.

❓ Frequently asked
Is there an official rent-increase form in Liechtenstein?
No. The old law required one, but the reform of 1 January 2017 abolished it. All that is required today is written notice plus reasons — and if either is missing, the increase is void.
Can I go to a conciliation board like in Switzerland?
No, tenancy conciliation boards do not exist in Liechtenstein. The mediation offices were abolished on 1 July 2015, before the new tenancy law even took effect, so every challenge goes straight to the Landgericht.
How long do I have to challenge an increase?
Four weeks from the notice, and the challenge must be filed in court (Art. 62). Miss the deadline and the claim is forfeited — the increase then stands for good, even if it was substantively unlawful.
Can the landlord threaten me with termination in the same letter?
No, and doing so actually makes the increase void. Art. 59(3) states expressly that a notice is ineffective if the landlord simultaneously threatens or issues a termination.
Does rent protection cover every flat?
No. Flats above 150 m² of net living space and detached houses above 200 m² are excluded from rent protection under Art. 3(2). In that luxury bracket there is practically no control over increases.
