Renting in Vienna: Altbau, rent rules and the Maklerprovision

Vienna is a city of renters, and for an American arriving with a residence permit in progress, finding a flat is usually the first big practical task. The market has its own vocabulary and a set of tenant protections that are stronger than most Americans expect, but those protections depend on the type of building and contract. This guide explains the parts that matter, drawing on the City of Vienna, the federal oesterreich.gv.at portal and the federal migration portal.

Main lease or sublet

The first question on any listing is what type of contract you would get.

• Main lease (Hauptmiete): you rent directly from the owner. This is the stronger position and the one to aim for if you will stay for years.
• Sublet (Untermiete): you rent from someone who is themselves a tenant. Sublets are common for furnished, short stays and are easier to get without Austrian credit history, but your rights depend on the main tenant's contract.

Whichever you sign, the person who provides the flat must sign your registration form, the Meldezettel, so you can register the address within three days of moving in. Ask about this before you pay anything. A landlord who will not sign is a red flag, because registration is a legal duty and you need the confirmation for your residence card.

Limited and unlimited leases

Many Vienna leases are time-limited. The federal portal oesterreich.gv.at explains that for leases covered by the Tenancy Act, the minimum fixed term is five years, or three years if the landlord is not a business. After the first year, tenants can end a limited lease with three months' notice to the end of a month, so the earliest exit is at the end of the 16th month. Unlimited leases are harder to come by but give the most security.

For your residence application, a three-year lease is often the most practical proof of accommodation, since it shows a legal title to a place to live for the length of a first permit and beyond.

Altbau and the rent cap

Vienna's old buildings, the Altbau, are where rent law bites hardest. The City of Vienna's rent calculator explains that the reference value system (Richtwert) applies to flats in buildings with more than two units built under a construction permit issued before 1 July 1953, and to flats in condominium buildings with a permit before 9 May 1945, when the lease was signed after 28 February 1994.

For those flats, rent is capped at the Richtwert for the province, plus or minus defined surcharges and deductions. One surcharge is the location surcharge (Lagezuschlag), allowed only where the building sits in an area with above-average infrastructure. The city publishes a location surcharge calculator so tenants and landlords can see whether it applies.

Newer subsidised buildings have their own rules. Buildings built privately after the cut-off dates are generally outside the Richtwert cap, which is why two flats on the same street can have very different rents.

If you suspect you are paying more than the legal cap, the city's arbitration board for housing matters (Schlichtungsstelle, MA 50) handles rent reviews, checks of flat category, service charges and floor area, and claims for prohibited key money. The city's tenant help line, MieterHilfe, answers general questions on +43 1 4000-8000.

The broker fee: who pays since 2023

Since 1 July 2023 Austria applies the "orderer pays" principle to rental brokers. The federal portal explains that flat seekers only pay a broker's commission if they themselves commissioned the broker. In practice the landlord usually instructs the agent, and then the landlord pays.

If you do hire a broker yourself, the commission is capped:

• up to two gross monthly rents for unlimited leases or leases longer than three years;
• up to one gross monthly rent for leases of up to three years;
• one more gross rent may be charged if a limited lease is later extended past three years or made unlimited;
• 20 percent VAT is added on top.

Gross rent here means the base rent plus operating costs, without VAT. Heating costs are never part of the base for the commission.

What the monthly cost includes

Listings usually show a total that combines base rent, operating costs (Betriebskosten) such as building maintenance, water and waste, and VAT. Electricity and often heating are separate contracts in your own name. Ask for the breakdown and for last year's operating cost statement.

On top of rent, expect a deposit. The amount is a matter of the contract, so read the clause on when and how it is returned.

Documents landlords ask for

Expect to be asked for:

• your passport;
• proof of income, such as an employment contract or pension statements;
• for employees, recent payslips once you have them;
• sometimes a reference from a previous landlord.

Because you may not yet have Austrian payslips, a signed Austrian employment contract or clear statements of foreign income help.

Sharing a flat

If you are sharing with friends or a partner who is not your spouse, the structure of the contract matters. The migration portal describes two common setups. In the first, one person signs the lease and the others move in as co-tenants. The risk is that if the person who signed moves out, the lease may not pass to the others and everyone may have to leave. In the second, all residents sign the lease and enjoy equal legal protection, so one person leaving does not change the agreement for the rest. If you are the newcomer in a shared flat, ask which setup applies and whether your rights are written down.

Extending a limited lease

When a limited lease is extended, the three-year minimum applies again to the extension. The tenant is not bound to stay for the full extended term and can still give three months' notice. Landlords sometimes offer a short extension on different terms; compare it against what the law says before you agree.

A practical sequence for Vienna

1. Decide between a sublet for the first months and a main lease from the start.
2. Check whether the building falls under the Richtwert cap using the city's calculator.
3. Confirm who commissioned the broker before you sign anything.
4. Get the Meldezettel signed when you receive the keys.
5. Register at a Meldeservicestelle within three days.
6. Set up electricity and internet in your name.

When you buy instead

If you decide to buy, the migration portal advises budgeting about ten percent of the purchase price for the additional costs of buying, such as taxes, fees and charges. The portal lists notary fees, taxes, official charges, financing fees and estate agent commissions among those costs. Property acquisitions must be entered in the land register, and the portal recommends using a notary or lawyer for the process.

Common questions

Do I have to pay the agent's commission on a Vienna rental? Only if you commissioned the agent yourself. Since 1 July 2023 the party that orders the broker pays, which is usually the landlord.

How do I know whether my Altbau rent is capped? Use the City of Vienna's rent calculator. Flats in older buildings with more than two units, leased after 28 February 1994, generally fall under the Richtwert cap with permitted surcharges.

How long must a limited-term lease run? Five years for leases covered by the Tenancy Act, or three years if the landlord is not a business. After one year, tenants can give three months' notice to the end of a month.

What if my landlord refuses to sign the Meldezettel? Registration is a legal duty for you and the accommodation provider must sign. Treat a refusal as a serious warning sign before paying anything.
