SUMMARY
Vienna apartments can still legally work as Airbnbs, but full-time use is now concentrated in properly authorised accommodation premises and ordinary apartments outside a Wohnzone with a clean §129 exemption. For everyone else, Airbnb should usually be treated as a limited side use rather than the core investment case.
The July 2024 reform changed the market more than the old Wohnzone rules did. An ordinary residential apartment generally needs special permission once short-term letting exceeds 90 days per calendar year, even if the property sits outside a protected Wohnzone.
The remaining 90-day exception is much narrower than it first sounds. It protects genuine residents who temporarily share their own home; it does not automatically turn a vacant investment apartment into a legal 90-day Airbnb, and a company cannot use the exception at all.
For investors, the building has become almost as important as the apartment. A §129 application depends on subsidy history, the proportion of residential use in the building, the concentration of short-stay units and specific co-owner consent, so an otherwise perfect apartment can fail because of what is happening elsewhere in the property.
Co-owner consent is now a particularly awkward hurdle. Recent Verwaltungsgerichtshof decisions indicate that a general clause in a condominium agreement allowing short-term rental does not replace the specific consent required for the actual §129 project.
Ordinary apartments inside a Wohnzone are weak candidates for dedicated tourist letting. There are specialist routes under §7a, especially for unusual premises with poor residential quality or buildings that retain enough protected housing, but buyers should not assume a conventional central Vienna apartment can simply be converted later.
Properly authorised accommodation premises are structurally stronger. A unit already approved as a Beherbergungsstätte or comparable accommodation establishment is operating under a legal use that actually fits tourist accommodation instead of relying on a temporary exception for a normal apartment.
A 31-night minimum stay is not a reliable loophole. Vienna looks at the real character of the letting, so a genuine several-month relocation tenancy is different from a continuously rotating tourist business whose bookings have simply been engineered to last one day longer.
Even a valid §129 decision does not solve every problem. Condominium law, lease restrictions, trade-law classification, fire safety, guest registration, tourism reporting and Vienna's Ortstaxe can all remain relevant after the planning permission has been obtained.
Enforcement is no longer theoretical: Vienna recorded 1,620 reports of suspected illegal short-term rentals in 2025, forwarded 374 cases for penal proceedings and has carried out targeted inspections of hotel-style operations. The practical buying rule is therefore simple: unless current documents prove otherwise, value a Vienna apartment as ordinary residential property and give historical Airbnb revenue no premium.

Which Vienna apartments can still legally work as Airbnbs?
What changed for Airbnb apartments in Vienna?
Vienna now makes full-time Airbnb use of an ordinary residential apartment much harder than it was a few years ago.
The big change came when Vienna extended its short-term-rental rules across the whole city. Since July 2024, even an apartment outside a designated Wohnzone generally needs a special exemption under §129(1a) of the Vienna Building Code if it is offered for short-term rental for more than 90 days per calendar year. Before that, Wohnzonen were the main planning-law obstacle. Today, being outside one no longer gives an investor a free pass.
The first full year of enforcement shows that Vienna is actually using the rules. MA 37, the city's building authority, recorded 352 applications for short-term-rental permits in 2025. During the same year, it received 1,620 reports of suspected illegal short-term rentals exceeding 90 days and forwarded 374 cases to MA 64 for penal proceedings. Roughly 23% of the reports were therefore forwarded that far.
Vienna has also started carrying out targeted building inspections rather than relying only on complaints. One operation in Favoriten found a residential building where several apartments were being used as tourist accommodation without the required commercial permissions. Another set of inspections in the 4th and 10th districts led MA 37 to describe two operations as illegal hotels and send 34 penal applications onward.
For an investor, the practical change is simple: Airbnb legality in Vienna now has to be checked apartment by apartment and building by building.
| Vienna Airbnb rule or enforcement measure | Current position | Scale | What it means for an owner |
|---|---|---|---|
| >90 days of short-term letting | Special permission normally required | Citywide | Being outside a Wohnzone is no longer enough |
| §129 exemption duration | Maximum 5 years | Temporary | Airbnb income cannot automatically be valued as permanent |
| Permit applications in 2025 | 352 | Hundreds | The exemption route is being actively used |
| Suspected illegal rentals reported in 2025 | 1,620 | More than four times permit applications | Enforcement risk is real |
| Cases sent for penal proceedings | 374 | About 23% of reports | A meaningful share moves beyond the complaint stage |
Can you Airbnb your own Vienna apartment for 90 days?
Yes. Vienna still allows genuine home-sharing for up to 90 days per calendar year when the apartment remains the host's real residence.
This is the cleanest Airbnb exception left for an ordinary Vienna apartment. The city's own guidance gives examples such as a student renting out a home during university holidays or a resident letting the apartment while travelling. The important condition is that the person has not permanently given up living there.
That also applies when the home is inside a Wohnzone. A genuine resident in a protected central neighbourhood can therefore use Airbnb occasionally without obtaining the special §129 permit, provided the total stays remain within the 90-day annual limit and the other legal requirements are respected.
The rule becomes much less useful for investors. Vienna describes it explicitly as home-sharing, and companies cannot use it at all because a legal person cannot have a residential domicile. An individual who buys a vacant investment property should not assume that leaving it empty for 275 days automatically creates a legal 90-day Airbnb entitlement either. The exception is tied to continuing residential use.
So there is still a meaningful 90-day Airbnb market in Vienna today, but it mainly protects residents who occasionally rent their homes rather than investors building dedicated short-stay portfolios.
| Situation | Can the 90-day home-sharing exception work? | Why |
|---|---|---|
| Owner lives in the apartment and rents while travelling | Yes | This fits Vienna's home-sharing model |
| Student rents their home during holidays | Yes | Vienna explicitly gives this example |
| Resident lives inside a Wohnzone | Yes | Wohnzone status does not remove genuine home-sharing |
| Individual owns a vacant investment apartment | Not automatically | The home-sharing rule assumes continued residential use |
| GmbH or other company owns the apartment | No | Companies cannot have the required residential domicile |
Before you sign the Kaufanbot, read what buyers learned
The details that feel routine at this stage are often where buyers get caught. See the real cases, the paperwork they trusted and what they should have checked first.
Can an investment apartment outside a Vienna Wohnzone still run on Airbnb year-round?
Yes, but a normal Vienna investment apartment outside a Wohnzone needs a §129 exemption to exceed 90 days, and getting one is far from automatic.
The permit lasts for no more than five years. To qualify, the apartment must sit outside a Wohnzone and outside several protected allotment or recreational land categories. Housing-development subsidies must not have been used for the apartment's construction.
The whole building then comes into play. A majority of the apartments must continue to be used residentially, while commercial short-term accommodation cannot exceed 50% of the building's usage units.
Imagine a building with 20 usage units. If nine are already being used for commercial short stays, permission for another unit may still fit under the 50% ceiling. Turning two more into tourist units would take the building to 11 out of 20 and breach it. An apartment that looks perfect when viewed on its own can therefore fail because of what other owners are already doing.
This is where the paperwork gets awkward. Before buying for Airbnb, we would want to know the approved use of the unit, whether housing subsidies were involved, how many other short-term units exist and what MA 37's approved plans show. Those details now matter at least as much as the distance to Stephansplatz.
| §129 test for a Vienna Airbnb over 90 days | What currently has to be true | Investor implication |
|---|---|---|
| Location | Outside a Wohnzone and specified protected land categories | Check the exact plot, not just the district |
| Housing subsidies | No qualifying Wohnbauförderung used for construction | Subsidy history can kill the application |
| Residential use | Majority of apartments must remain residential | Building composition matters |
| Short-stay concentration | Maximum 50% of usage units | Existing Airbnbs can reduce remaining capacity |
| Co-owner consent | Specific consent from all relevant co-owners | One owner can become a major obstacle |
| Duration | Maximum 5 years | Renewal risk has to be priced in |
Do all the other owners have to approve a Vienna Airbnb?
For the main §129 Airbnb route, yes, and recent Austrian court rulings have made that hurdle harder to sidestep.
Vienna requires written consent from all co-owners for the specific short-term-rental project. That already made large condominium buildings awkward: the more owners there are, the more chances there are for one person to object.
A recent line of Administrative Court decisions removed one apparent shortcut. In its August 2025 ruling Ra 2025/05/0007, the Verwaltungsgerichtshof held that a general clause in a Wohnungseigentumsvertrag allowing short-term rental does not replace the specific consent required under §129. The court repeated that position in further decisions in November 2025 and again in a 2026 case.
That repetition is important. We are no longer dealing with one unusual judgment that might have been confined to its facts. The court has applied the same principle several times.
There is also a separate condominium-law issue. Austria's Supreme Court has previously held that repeated tourist rentals can amount to a change in the designated use of a condominium unit and, depending on the circumstances, require agreement from the other owners because of the constant turnover of guests.
So when an estate agent says that a Vienna apartment is “Airbnb allowed,” we would ask a much more precise question: where is the current, project-specific consent from the co-owners?
What Austrian property buyers wish they had checked earlier
Locals know which questions are normal and which red flags matter. We collected the problems buyers actually ran into, not generic advice.
Can an ordinary apartment inside a Vienna Wohnzone still be a full-time Airbnb?
Usually not through the easy route. A normal apartment inside a Vienna Wohnzone is currently one of the weakest choices for a dedicated full-time Airbnb investment.
The §129 exemption used by ordinary apartments outside Wohnzonen is unavailable there. Regular tourist use instead has to fit the much stricter rules protecting residential floor space under §7a of the Vienna Building Code.
There are possible exceptions. Vienna can allow non-residential use where at least 80% of the relevant above-ground usable floor area remains residential. The building rules also recognise situations where an apartment has unusually poor residential quality because of noise, lack of daylight, poor ventilation or an unfavourable ground-floor position.
That produces a slightly counterintuitive result. A beautiful third-floor Altbau apartment in a protected residential zone can be harder to convert than a dark ground-floor unit facing a noisy road. The second apartment may have a stronger argument that keeping it as protected housing serves little purpose.
But this is specialist planning territory. Buying a conventional apartment in Innere Stadt, Neubau or another protected area and assuming that year-round Airbnb permission can later be arranged is a weak strategy today.
Could a former shop or office make a better Vienna Airbnb?
Sometimes, although a former shop or office needs the right accommodation approval rather than the ordinary apartment exemption.
Vienna's MA 37 guidance makes this distinction quite clearly. The §129 exemption applies to premises legally designated as apartments. An office, shop, studio or other business unit cannot simply apply under §129 and become a tourist apartment.
Instead, the owner may need approval to convert the premises into a Beherbergungsstätte, essentially an authorised accommodation establishment.
That route can involve more planning work, fire requirements and potentially higher conversion costs. Yet the result can be stronger for a serious Airbnb investor. A properly authorised accommodation unit does not depend on a five-year exception allowing an ordinary apartment to be used commercially.
Purpose-built aparthotels and other properly approved accommodation units belong in the same category. Guests may book them through Airbnb, Booking.com or directly; the booking website does not determine their legal status.
This is one reason some of Vienna's best short-term-rental opportunities these days may look less like classic residential property investments. Properly authorised accommodation can be worth more to an operator than a beautiful apartment with uncertain Airbnb rights.
Buying a home in Vienna? Learn from people who already did it
We sorted real buyer mistakes by the moment they happen, from first checks and offers to contracts, money transfers and the keys.
Can a company buy a Vienna apartment and use the 90-day Airbnb rule?
No. A company that owns an ordinary Vienna apartment cannot use the personal 90-day home-sharing exception.
Vienna's building authority explicitly says that legal persons cannot rely on the exemption because a company has no Wohnsitz. The logic is consistent with the rest of the rule: the 90 days are meant for someone temporarily sharing their own home.
A GmbH buying a residential apartment for short-term rental therefore needs another legal route, usually a §129 exemption where the property qualifies or a proper accommodation designation.
That creates a real distinction between owner-occupiers and professional investors. A person who genuinely lives in a Vienna flat retains limited short-term-rental flexibility. A company holding the same physical apartment does not. Not ideal for a portfolio built around ordinary flats.
Can a tenant legally put a Vienna apartment on Airbnb?
Sometimes, but a Vienna tenant has an extra legal problem because the lease can block Airbnb even when building law would otherwise allow the stay.
A tenant who genuinely lives in the apartment could potentially fall within the 90-day home-sharing framework. That still does not override a contractual restriction on subletting or handing the property to third parties.
Vienna specifically tells tenants to check their rental agreements for these restrictions. Municipal housing is stricter again. Wiener Wohnen leases prohibit unauthorised subletting or transfer to third parties, and breaching the rule can put the tenancy itself at risk.
The same basic issue applies to student accommodation where subletting is prohibited.
For a renter, then, “Vienna allows 90 days of home-sharing” is only half the answer. The lease has to allow the arrangement too.
The traps foreign buyers keep discovering in Austria
Foreign buyers use different agents, documents and assumptions. See the problems that show up when you do not know the local shortcuts yet.
Does a 31-night minimum stay get around Vienna's Airbnb rules?
No. We would not buy a Vienna apartment on the assumption that setting Airbnb to a 31-night minimum makes the short-term-rental rules disappear.
Vienna says the length of a short-term rental has to be assessed from the circumstances of each case. Its MA 37 FAQ refers to Austrian Supreme Court case law using stays of roughly two to 30 days as a useful benchmark, but it does not establish 31 days as a statutory safe harbour.
That leaves room for longer furnished stays, of course. Someone taking an apartment for several months for work, study or relocation does not look much like a tourist staying four nights.
The risky version is a property continuously marketed to rotating temporary guests where every booking happens to last 31 nights because the owner is trying to sit one day beyond the commonly quoted benchmark. Recent litigation around longer stays shows why we should not treat that number as a magic switch.
A medium-term-rental strategy can still make sense in Vienna. It just needs to look and operate like real medium-term housing rather than an Airbnb business engineered around one extra night.
Does a Vienna Airbnb permit solve every legal problem?
No. A Vienna §129 permit deals with building-law permission, while an Airbnb operator can still face separate condominium, trade, fire-safety, registration and tax requirements.
Fire rules are one example that has become more concrete lately. MA 37 published dedicated guidance in 2025 setting out fire-safety requirements for §129 short-term rentals and accommodation establishments, with the applicable measures changing according to factors such as bed capacity and the building itself.
The commercial setup matters too. Austrian law can distinguish simple letting of premises from operating a hospitality business depending on what services the host provides. Cleaning, linen, equipment and other guest services can affect that assessment.
Vienna also requires accommodation providers to keep guest records, while tourism statistics have to be reported under the applicable rules. The city's Ortstaxe applies to paid accommodation and has its own registration and payment obligations.
This is why the MA 37 decision should be treated as the central planning document rather than an all-purpose Airbnb licence.
| Legal layer | Typical question to check | Why it can still matter after §129 approval |
|---|---|---|
| Vienna Building Code | Is short-term use approved? | Determines whether the apartment can be used this way |
| Condominium law | Have the necessary owners agreed? | Neighbours can have separate civil-law rights |
| Trade law | Is the activity simple letting or hospitality? | Services can change the legal classification |
| Fire safety | Does the setup meet current MA 37 requirements? | Requirements depend on the property and guest capacity |
| Guest reporting | Are guests being properly registered? | Accommodation providers have reporting duties |
| Ortstaxe | Is Vienna accommodation tax being collected and remitted? | Operating legally includes tax compliance |
What Austrian owners say catches buyers off guard
Owners talk about the defects, fees, clauses and promises that looked harmless before the deal. Their stories show where to slow down.
Is Vienna actually cracking down on illegal Airbnbs now?
Yes. Vienna's enforcement numbers and targeted inspections show that illegal short-term rentals are currently being pursued much more actively than an investor should be comfortable ignoring.
MA 37 recorded 1,620 reports of suspected illegal short-term rentals in 2025 and sent 374 cases for penal proceedings. As seen above, that works out to roughly 23% of reported cases reaching that stage.
The way Vienna investigates is equally relevant. The city's dedicated Kurzzeitvermietung control unit can research listings on platforms such as Airbnb and Booking.com and carry out on-site checks. Enforcement therefore does not depend entirely on an angry neighbour supplying perfect evidence.
Targeted operations have also moved beyond individual flats. During inspections in the 4th and 10th districts, the building authority said it uncovered two illegal hotel-style operations. Another operation in Favoriten involved numerous apartments in one residential building and triggered scrutiny under several different rules.
The maximum building-law fine for offering an apartment illegally for more than the permitted 90 days can reach €50,000 according to Vienna's MA 37 FAQ.
A few years ago, some investors could plausibly treat enforcement uncertainty as part of the business model. Today that looks much harder to justify.
Is an existing Vienna Airbnb listing proof that the apartment is legal?
No. Seeing a Vienna apartment actively listed on Airbnb tells us almost nothing about whether the property has the permissions needed to keep operating.
A listing can exist while an owner is under the 90-day home-sharing limit, while a permit is valid, while an application is disputed, or while the operation is simply illegal. Airbnb availability does not reveal which situation we are looking at.
Historical revenue is equally weak evidence. An apartment may have generated excellent tourist income under the rules that existed before the citywide reform, while the new owner now faces a very different legal position.
We would want to see the actual MA 37 decision where a permit is required, what apartment it covers, when it expires and what conditions were attached. We would also check the approved building plans, Wohnzone status, subsidy history, current co-owner consents and the Wohnungseigentumsvertrag.
Recent Administrative Court decisions make the last point especially important. As pointed out above, even a general short-term-rental clause in the condominium agreement does not necessarily provide the specific consent MA 37 needs for a §129 project.
Past Airbnb revenue can tell us something about demand. It cannot prove future Airbnb legality.
Don't discover after signing what other buyers learned too late
Some of the most expensive property mistakes look obvious only afterwards. Read the cases before the contract makes them your problem.
Which Vienna apartments are the safest Airbnb buys today?
The safest Vienna Airbnb buys today are properties where frequent tourist accommodation is already supported by the legal status of the property, followed by ordinary apartments with a strong and recently verified §129 permit file.
A properly authorised Beherbergungsstätte or genuine aparthotel-type unit sits at the strongest end because short-term accommodation forms part of what the premises are actually allowed to do. The investment does not depend on persuading Vienna to tolerate commercial use of a normal apartment for another five-year period.
An ordinary apartment outside a Wohnzone can still be a viable second choice when the §129 position is clean. We would want the exemption itself, current project-specific co-owner consent, confirmation that no disqualifying housing subsidy was used and enough room below the building's 50% short-stay ceiling.
The permit's remaining life deserves close attention. A §129 approval can last no more than five years, and Vienna's FAQ says another application can only be considered after the existing period expires. A flat with four and a half years left on a permit is therefore a different investment from one whose approval expires next year.
We would be much more cautious with an ordinary apartment inside a Wohnzone unless a specialist has already established a credible §7a route. At the bottom are properties sold mainly on claims such as “currently on Airbnb,” “historically high occupancy” or “Airbnb allowed in the building.” None of those claims proves that a buyer can legally reproduce the previous owner's business.
| Vienna property type | Airbnb position today | Main risk | Our view |
|---|---|---|---|
| Properly authorised accommodation / aparthotel unit | Strongest | Operating and building-specific compliance | Best structural fit |
| Apartment outside Wohnzone with clean §129 approval | Viable | Five-year limit and future renewal | Good if documentation is strong |
| Genuine owner-occupied home | Up to 90 days | Must remain a real residence | Good for home-sharing, not a pure investment |
| Apartment outside Wohnzone without permit yet | Possible | Consent, subsidy and building tests may fail | Buy only if Airbnb economics are not essential |
| Ordinary apartment inside Wohnzone | Difficult for full-time Airbnb | Much stricter §7a rules | Weak speculative Airbnb buy |
| Apartment marketed as “Airbnb allowed” without current paperwork | Unproven | Legal use may disappear after purchase | Treat as normal residential property |
So which Vienna apartments can still legally work as Airbnbs?
Yes, Vienna apartments can still legally work as Airbnbs, but full-time Airbnb investing now survives in a fairly narrow group of properties.
For ordinary residents, the answer remains relatively simple. Someone who genuinely lives in a Vienna apartment can normally home-share it for up to 90 days per calendar year without the special §129 exemption, including inside a Wohnzone, provided the other legal and contractual rules are respected.
A dedicated investor needs more. Outside a Wohnzone, an ordinary apartment can exceed 90 days with a §129 exemption, but it has to clear the subsidy rules, building-level residential thresholds and the requirement for specific co-owner consent. The permit lasts no more than five years.
Inside a Wohnzone, continuous tourist use is considerably harder. Some unusual properties can qualify through §7a, particularly where residential quality is poor or enough protected housing remains in the building, but we would treat that as a specialist conversion project rather than ordinary Airbnb investing.
Properly authorised accommodation premises are the strongest full-time option. They cost more effort to identify and sometimes more to buy or convert, but their legal basis fits the business far better.
The practical rule for buyers is therefore quite strict these days: unless the current paperwork proves otherwise, value a Vienna apartment as a normal residential property and give it zero Airbnb premium. A live listing, strong historical revenue or an old clause saying short-term rentals are allowed is no longer enough.

OUR METHODOLOGY
This analysis tests which Vienna apartments can still support legal short-term tourist accommodation under the rules in force today. We separated occasional home-sharing from dedicated investment use, ordinary residential apartments from authorised accommodation premises, and properties inside Wohnzonen from those outside them.
We did not treat an active Airbnb listing or historical Airbnb revenue as proof of legality. Instead, we focused on the legal use of the premises, whether the host genuinely resides there, the applicable planning route, building-level restrictions, co-owner consent, permit duration and the other operating rules that can still apply after building-law approval.
For the core planning framework, we prioritised the City of Vienna and MA 37. The main sources include Vienna's guidance on renting apartments for tourist purposes, the City's §129 short-term-rental exemption requirements, MA 37's guidance note on short-term rental use and MA 37's short-term-rental FAQ.
We checked the statutory framework directly through Austria's Legal Information System, including §129 of the Vienna Building Code and §7a on Wohnzonen. These provisions are the basis for the distinction between the citywide exemption route for qualifying apartments and the much stricter treatment of protected residential floor space inside Wohnzonen.
We then used court decisions to test how those rules are being interpreted in practice. Particular weight was given to the Verwaltungsgerichtshof's Ra 2025/05/0007 decision of 27 August 2025 and the later decisions that repeated its approach to project-specific co-owner consent. We also used the Austrian Supreme Court's 5 Ob 59/14h decision for the separate condominium-law issue created by repeated tourist use.
Enforcement was assessed from official Vienna records rather than anecdotal complaints. We used MA 37's 2025 performance report for permit applications, suspected illegal rentals and referrals for penal proceedings, together with Vienna's reports on targeted inspections in the 4th and 10th districts and the Favoriten short-term-rental inspection operation. We use those figures to show enforcement intensity, not to estimate an individual owner's probability of being prosecuted.
For the operating layer, we also checked MA 37's fire-safety guidance, Vienna's guest-register requirements, tourism-statistics reporting rules, Ortstaxe requirements, the Austrian Federal Economic Chamber's guidance on the boundary between letting and commercial accommodation, and Wiener Wohnen's rules on subletting municipal housing.
Our ranking is based on legal robustness, not on theoretical possibility. We therefore rank premises already authorised for accommodation above ordinary apartments relying on temporary exemptions, and we rank undocumented claims such as “Airbnb allowed” or historical occupancy below current permits, approved plans and project-specific consents.
