Tiny house in Germany: permit rules and where to live

Tiny house on a trailer, weekend house, allotment cabin: when German law needs a permit, why living there is often banned, and where it is legal.

A Bavarian weekend-house estate had 121 plots. On 87 of them people lived permanently or had their main residence, nearly three in four. The owners argued that the development plan was dead and permanent living should be allowed. The Bavarian Higher Administrative Court disagreed (judgment of 25 October 2023, 9 B 22.1461 and others): a plan designating a weekend-house area has not become obsolete just because 87 of 121 plots are used as homes.

Cheap weekend houses by a lake, "leisure plots" on the edge of a village and meadow plots for a tiny house attract many buyers from abroad, especially around Berlin and in Bavaria. In German law you may build many things, but you may live permanently only where planning law allows housing. This guide separates the three common cases and shows with court decisions where the line runs. It is an overview, not advice from the building authority; building regulations are state law and vary.

Tiny houses: wheels change nothing

The model building code that the state codes follow defines a structure as something connected to the ground and built from building products; it counts as connected if it is meant to be used mainly in one place (section 2(1) MBO). Courts apply this strictly:

  • Berlin-Brandenburg Higher Administrative Court, 22 June 2023, OVG 10 S 15/23: a timber-frame tiny house on a trailer is a structure under the Brandenburg building code; vehicle registration makes no difference; the order prohibiting its use was upheld.
  • Munich Administrative Court, 8 May 2023, M 8 S 23.2010: a stationary tiny house at the back of a garden plot; the prohibition stood.
  • Baden-Württemberg parliament, document 16/7708: the state government states that tiny houses are structures and, as buildings with living space, toilet and heating, not exempt from permits.

So a tiny house you live in goes through the same building procedure as a detached house (a permit application or, in some states inside a development plan, a permit exemption procedure), and it must be allowed by planning law. Our comparison of permit-free works shows what small structures each state exempts; homes are not among them.

Where it can work:

  • In a residential zone with a development plan, if it meets the plan. Some plans set minimum sizes or roof shapes a 25 m² house cannot meet. See zoning and buildability.
  • In a built-up area without a plan (section 34 BauGB), if it fits in with its surroundings.
  • As a second house in a garden, only if the plot allows another home, with setbacks, parking and access.
  • In the countryside (Außenbereich): practically never as a home; see building in the outer area.
  • On a campsite: only under the site's rules. Ask the operator and the town in writing whether permanent living is allowed before you move the house there.

Importing a tiny house: a unit built abroad becomes a building under the state building code once it stays put, and has to meet that code's requirements. Ask the maker for documents a German engineer can use before you ship it.

Where towns plan for tiny houses

The safest option is a plot in a zone planned for small houses. Two examples from North Rhine-Westphalia show what that looks like:

  • Jülich, Lindenallee III: the town's development company SEG Jülich offers 16 tiny-house plots of 145–334 m², not for sale but on a ground lease (Erbbaurecht): 60 years, notarised contract, ground rent of about €18 per m² a year according to SEG, with an annual special right for the leaseholder to terminate.
  • Menden (Sauerland), Sauerlandstraße: the council adopted the development plan and a design code on 3 February 2026; the plan has been in force since 18 February 2026. Plots are sold, not leased.

The Jülich maths: a 200 m² plot costs 200 × 18 = €3,600 a year, or €216,000 nominal over the full term before any rent review. In return you pay no land price and no transfer tax on the land. For someone testing life in Germany, the termination right matters more than the total. The counter-example is Löffingen in the Black Forest, whose draft plan "Ferienhaussiedlung Tiny House Village" (public display, January 2021) is a holiday-home estate, not for a main residence. Identical houses, different planning law. The zone type is printed on the plan drawing; read it before you reserve a plot.

Weekend houses: build yes, live no

Weekend-house areas are special zones for recreation (section 10 BauNVO). Weekend houses are allowed as detached houses, and the plan must fix the permitted floor area (section 10(3)). Reference values for such zones are 0.2 for plot and floor-area ratios (section 17 BauNVO). Plans often cap floor area at 40, 50 or 60 m²: on a 600 m² plot a ratio of 0.2 would give 120 m², but a cap of 50 m² wins.

What the difference is worth, with assumed figures: if the standard land value (Bodenrichtwert) is €60/m² in the weekend-house zone and €180/m² in the residential zone next door, a 600 m² plot is worth €36,000 as a weekend plot and €108,000 as a building plot. Pay €90,000 because "people live there anyway" and you have paid €54,000 for a use that does not exist, plus transfer tax on it. Real values are in BORIS, the official land value portal of each state; some valuation committees show weekend-house zones as a separate zone.

The Federal Administrative Court settled the principle in 2013 (11 July 2013, 4 CN 7.12): permanent living is incompatible with the purpose of a recreation zone. Permitted homes that existed before the plan keep protected status. A mix of permanent and holiday homes is possible in a different kind of special zone (section 11 BauNVO; Federal Administrative Court, 18 October 2017, 4 CN 6.17), not in a classic weekend-house area.

Owners who live there anyway face orders: the Munich Administrative Court upheld a ban on permanent living in a weekend-house zone (19 March 2021, M 9 K 20.688). And as the 121-plot case shows, a majority of permanent residents does not invalidate the plan.

Registration is not permission. Foreign buyers often need a registered address in Germany for a tax ID, a bank account or a residence permit, and may be able to register at a weekend house. Registration is a matter of registration law, not planning law: it does not make permanent living lawful. The ban on living there comes from the development plan and section 10 BauNVO, and a registration certificate does not override it.

When towns try to rezone

Many towns, especially around Berlin, have weekend-house zones where people live year-round. Brandenburg has published guidance: a rezoning fails if it breaches the joint Berlin-Brandenburg state planning targets. Since the 2017 amendment of the Building Code, towns can adopt a project-based development plan (vorhabenbezogener Bebauungsplan) that also allows housing in a former recreation zone under section 10 BauNVO (section 12(7) BauGB). Saxony's municipal forum cites the weekend-house area "Schmölener Lache" in Bennewitz, near Leipzig, as an example.

How long rezoning can take shows in Kakenstorf, Harburg district (Lower Saxony). In the "Auf der Horst" estate, according to the local paper, only ten of 82 main buildings were still used as weekend houses. The weekend-house plan dates from February 1982. After about 13 years of preparation the municipality adopted a new plan allowing housing in November 2015. The Higher Administrative Court in Lüneburg struck it down in July 2018, on a claim by two residents whose plots the new plan designated as woodland. In February 2019 the municipality started again at the request of an owners' association. Residents told the paper: "We now live illegally in an unauthorised building." For the current state of the procedure, ask the municipality.

It can work: in Noer, district of Lindhöft (Schleswig-Holstein), a new development plan no. 2 is converting a weekend-house zone into a general residential zone with 29 units for permanent living, most of them already lived in year-round. There is also a middle way. The Federal Administrative Court held in 2014 that a plan can protect existing homes inside a weekend-house zone (11 September 2014, 4 CN 3.14): those homes may stay, without the whole area becoming residential.

Rezoning costs owners money. In Neu-Anspach (Hesse), a 2024 council paper (no. 218/2024) proposed that owners pay 100% of the cost of changing the plan and, instead of the usual 90%, all of the infrastructure costs, citing the sharp rise in land value after rezoning. Even as a proposal it shows the scale of what towns may ask owners to pay. If you buy in the hope of rezoning, you know neither the outcome nor the bill.

Allotment cabins: 24 m² and no permanent bed

In an allotment under the Federal Allotment Gardens Act, a simple cabin of no more than 24 m² including a covered seating area is allowed, and its fittings must not make it suitable for permanent living (section 3(2) BKleingG). Larger cabins lawfully built before the Act keep protected status, and an existing right to live there remains (section 18). Occasional overnight stays are common; using the cabin as a permanent home despite a written warning is a ground for the landlord to give ordinary notice on the lease (section 9(1) no. 1 BKleingG).

A "leisure garden" sold as freehold land may not be an allotment at all, but plain countryside land, where the stricter outer-area rules apply.

Where buyers lose money

  1. "Living possible" in a weekend-house listing. Often it means someone already lives there, not that it is allowed.
  2. A tiny house on leased land or a relative's garden without a permit. Orders hit the landowner too.
  3. A leisure plot in the countryside with "protected status". Protection covers only what was lawfully built and lawfully used.
  4. Buying in anticipation of rezoning without a council decision.
  5. A tiny house in a holiday-home estate marketed as "living in the countryside". If the zone is a holiday-home zone, like Löffingen's draft, a main residence is as unlawful as in a weekend-house zone, however much the estate looks like a small village.

Before buying, ask the building authority in writing: what use is permitted for this building? Is there a permit for permanent living? Are proceedings open? If in doubt, a pre-application gives a binding answer: see permits and pre-applications. Buying from abroad generally: our guide.

Step by step before you buy

Step by step before you buy
  1. Zone type in the development plan. Most states and many towns publish plans online, in the state geoportal or on the town's site under "Bauleitplanung". "SO Wochenendhausgebiet", "SO Ferienhausgebiet" or "SO Erholung" means no permanent living unless the plan says otherwise.
  2. Floor-area cap and number of buildings; compare the ratio calculation with the cap.
  3. Building file (Bauakte) at the building authority, with the seller's written authority: is the permitted use "weekend house" or "residential building"? Any hearings, prohibition or demolition orders?
  4. Register of public-law obligations (Baulastenverzeichnis), except in Bavaria, which has none.
  5. Written answer from the building authority, or a binding pre-application. Ask precisely: "Is use as a main residence permitted on parcel …?"
  6. Notarial contract: have the notary record the permitted use, that the seller knows of no proceedings, and a right to withdraw if you are waiting for a permit. German notarial contracts are binding on signing, with no cooling-off period.

If you live abroad, a German-speaking architect or lawyer can inspect the file for you with a power of attorney; the authority will answer in German. A pre-application costs a fee under the state's fee rules plus the planner's fee; ask the authority for the fee before you file.

If the answer is bad

  • Not yet bought: negotiate down to the value of a weekend plot, or walk away.
  • Already living there and the authority writes to you: reply in writing within the deadline, and have someone check whether the house was ever permitted as a home (protected status) or can be permitted now. A prohibition order is an administrative act; the deadline to challenge it is stated at the end of the order.
  • The town is rezoning: take part in the public consultation, join other owners (as in Kakenstorf), and budget for planning and infrastructure costs, as in Neu-Anspach.
  • Tiny house without a permit: moving it to a tiny-house zone or a site where permanent living is allowed is usually faster than a dispute.

Common questions

My tiny house is registered as a trailer. Do I still need a permit?

Yes, if it stays and is used in one place. The Berlin-Brandenburg court said so explicitly.

In my country, holiday homes can sometimes be lived in under a personal permit. Is there a German equivalent?

Only through planning: a special zone allowing mixed use, a rezoning, or protection of existing homes in the plan. There is no individual exemption you can apply for in a weekend-house zone.

Can I spend the whole summer in a weekend house?

Yes, using it for recreation is the point of the zone. The problem is making it your permanent home.

I inherited a weekend house and have lived there for years. What can happen?

The authority can prohibit the use even after years if it was never permitted. Check whether a permit for permanent living exists or whether the house has protected status as a permitted home.

Is an allotment cabin a cheap second home?

No. It is a garden cabin by law and must not be fitted out for permanent living.

Is a ground lease a good way into a tiny-house plot?

Often, yes: no land price, an annual ground rent instead, about €18/m² in Jülich. Read the rent review, term and reversion (*Heimfall*) clauses before you sign at the notary.
