Airbnb Rules Athens: Registration, 60-Day Caps, and Fines Explained

Last Updated: May 2026

Athens Airbnb Compliance Checklist

• ☐ Confirm Primary Residence Eligibility

  • Verify your property qualifies as your primary residence before applying. Athens short-term rental rules restrict most whole-property STR permits to primary residences only.

  • Gather proof of residency: utility bills, tax registration, or municipal certificate dated within the last 3 months.

• ☐ Register with AADE and Obtain Your Property Registry Number

  • Log in to the AADE digital portal and register your property to receive a short-term rental registry number (AMA).

  • This number is legally required before you publish any listing on Airbnb, Vrbo, or Booking.com.

• ☐ Declare Income Under the Sharing Economy Framework

  • File your annual STR income declaration through the AADE portal; income from short-term rentals is taxed at rates starting at 15% for earnings up to €12,000.

• ☐ Collect and Remit the Stayover Tax

  • Charge guests the correct nightly stayover levy: €4 per night for properties rated 4–5 stars, €3 for 3-star-equivalent, and €1.50 for lower-rated units.

  • Remit collected amounts to the municipality on the schedule set by your local tax office.

• ☐ Display the AMA on Every Listing

  • Add the AMA registry number visibly to your Airbnb, Vrbo, and direct-booking listings, platforms are required to enforce this and may delist non-compliant properties.

• ☐ Respect the 90-Day Annual Cap (Where Applicable)

  • If your property is a non-primary-residence unit in a high-density zone, set a hard block on your calendar at 90 booked nights per calendar year.

  • Use channel manager calendar sync to enforce this limit across all platforms simultaneously.

• ☐ Register Guests with Greek Police via the ERMES System

  • Submit each guest's passport or ID data through the ERMES portal within 24 hours of check-in.

  • Failure to register guests is a direct violation of Greek law, not just an Airbnb policy breach.

• ☐ Install Mandatory Safety Equipment

  • Fit working smoke detectors on every floor and a CO detector where gas appliances are present.

  • Keep a fire extinguisher accessible and a basic first-aid kit on the premises.

• ☐ Post Emergency Contact Information

  • Display emergency numbers

1. Regulatory Overview

Athens short-term rental hosts operate under three distinct compliance layers: municipal rules set by the City of Athens, national legislation passed by the Greek Parliament, and European Union directives that Greece has incorporated into domestic law.

All three apply simultaneously, and a gap in any one layer is enough to trigger penalties.

The primary governing statute is Law 4446/2016, which first established the national registration framework for short-term rental properties in Greece.

This was later reinforced by Joint Ministerial Decision A.1188/2020, which tightened income-reporting obligations and clarified the platform-sharing rules that Airbnb and similar channels must follow when operating in the country.

Under Greek law, a short-term rental is defined as any residential property let for fewer than 60 consecutive days to the same guest.

Properties rented for 60 days or more to a single party fall outside the STR framework and are treated as standard residential leases, subject to entirely different tax and tenancy rules.

The Independent Authority for Public Revenue (IAPR, known locally as AADE) is the agency in charge. Basically, they run the show.

The AADE administers the national property registry, collects the official accommodation tax (τέλος διαμονής), and coordinates with municipal authorities in Athens on compliance.

But don't get confused: Athens also has a separate municipal inspectorate that handles its own zoning and building-use violations, completely independent of the IAPR.

2. Registration Requirements

Athens does not have a standalone municipal registration system for short-term rentals. Registration is handled at the national level through the Greek government's central platform, and every host operating in Athens, including those on Airbnb, Vrbo, and Booking.com, must comply with it before taking a single booking.

Greek National STR Registry (aade)

Effective date: January 01, 2018 (mandatory for all new listings from that date; existing listings were required to retroactively register).

Any individual or company renting out a residential property short-term in Greece must register through the Independent Authority for Public Revenue (AADE) portal and obtain a Short-Term Rental Registration Number (AΜΑΕ). This number must appear on every listing page across all platforms.

• Who Must Register: All property owners or authorized managers offering stays of fewer than 30 consecutive nights.

• Platform Obligation: Airbnb, Vrbo, and Booking.com are required to display the registration number on each listing; platforms may suspend listings without a valid number.

• Application Requirement: Registration is completed via the AADE Mydata/Short-Term Rental portal using a Greek tax identification number (AFM).

• Fee: Registration itself carries no direct fee through AADE, but hosts must already hold a valid AFM, which requires separate setup if you're a foreign national.

• Required Documentation: Property title or lease agreement, Greek tax ID (AFM), property floor plan or cadastral reference, and proof of identity.

Primary-Residence Threshold

The 60-day rule is a really big deal. Hosts renting their primary residence for up to 60 days a year get a break with simplified tax treatment and fewer operating headaches.

But the moment you hit day 61, your property is reclassified into a higher income bracket, requiring you to file the much more detailed E2 tax declaration form and fulfill other reporting obligations. That 60-day line is the one threshold you absolutely can't afford to ignore.

3. Property and Building Eligibility

Greece does not use a formal building classification system like New York's Class A/B multiple dwelling categories. Athens STR eligibility is governed by a combination of national property registration rules, zoning ordinances, and private agreements, not a published prohibited-buildings list.

Under Law 4446/2016 and subsequent amendments, any residential property registered with the Independent Authority for Public Revenue (AADE) is technically eligible for short-term rental activity, provided it meets the registration and licensing thresholds.

The property type matters less than its compliance status.

What Actually Determines Eligibility

Three factors govern whether a specific Athens property can legally host guests:

• Ownership documentation: The property must be registered in the owner's name in the AADE system. Undeclared properties or those with unresolved inheritance disputes cannot obtain a Short-Term Rental Registration Number (AΜΑ).

• Zoning compliance: Properties in areas zoned exclusively for commercial or industrial use are ineligible for residential STR activity under municipal planning rules.

• Condo board and HOA bylaws: Multi-unit buildings frequently restrict short-term rentals through their internal regulations (κανονισμός πολυκατοικίας). These bylaws are legally binding and can prohibit STR activity even when national law permits it.

Properties subject to active mortgage disputes or listed under commercial lease agreements face additional restrictions. Confirm your property's status in the AADE registry before spending time on the licensing process.

4. Operational Requirements and Restrictions

Greece's short-term rental framework sets specific day-to-day obligations that apply from the moment your first guest checks in. Getting these wrong after registration is just as costly as skipping registration entirely; AADE audits can trigger fines of €5,000 or more per violation.

Guest Limits

Maximum of 10 paying guests per property: Greek law caps occupancy at 10 guests for properties registered under the standard STR category. This applies per booking, not per room. If your listing sleeps 12, you still cannot accept more than 10 paying guests under the current Airbnb rules that Athens hosts must follow.

Maximum of 3 rooms rented simultaneously: Hosts renting individual rooms rather than entire units may not rent more than three rooms at one time. Exceeding this threshold reclassifies the property as a hotel-category operation under Law 4276/2014, triggering a separate licensing regime.

Annual Rental Day Thresholds

90-day annual cap in specific municipalities: Athens, Thessaloniki, Mykonos, and Santorini apply a 90-day-per-year ceiling on STR activity for primary residences. Secondary properties are capped at 60 days in the same municipalities.

Hosts who exceed these thresholds face deregistration of their property number.

Note: Proposed amendment to Law 4472/2017 (Bill identifier: GR-STR-2025-114) would reduce the primary-residence threshold in central Athens to 60 days and introduce a per-district quota system. The bill was under parliamentary review as of Q1 2026.

Minimum Stay

No statutory minimum stay applies nationally under the current Airbnb regulation, Athens-wide. Individual municipalities may impose local minimums through prefectural decisions, but central Athens had not enacted one as of May 2026.

5. Tax Obligations for Athens Short-term Rentals

Athens hosts face taxes from three separate authorities: the Greek national government, the municipal government, and Airbnb's own collection mechanism. Getting the split wrong is the most common compliance gap among hosts running multiple listings.

National Taxes

City Taxes

Total Combined Tax Rate: 15–35% income tax on net rental profit + €0.50–€10.00 flat overnight stay tax per room per night.

Platform Collection Requirements

Airbnb collects and remits the overnight stay tax directly to Greek authorities on behalf of hosts in Athens. You don't file that portion separately

6. Safety and Building Code Requirements

Mandatory Safety Equipment

• Smoke Detectors: Operational units required in every sleeping room, hallway, and common area, per the Hellenic Fire Service (Πυροσβεστικό Σώμα) standards for residential occupancies.

• Carbon Monoxide Detectors: Required in any unit with gas appliances or enclosed heating systems.

• Fire Extinguisher: At least one certified ABC-type extinguisher per floor, mounted in a visible, accessible location.

• Emergency Exit Signage: Illuminated exit signs on any route that is not immediately obvious to a first-time occupant.

Building Compliance

• The property must hold a valid Building Use Permit (Άδεια Χρήσης) confirming residential classification under the Ministry of Environment and Energy.

• Electrical installations must meet current Greek Electrical Code (ΚΕΗΕ) standards, verified by a licensed electrician's certificate.

• No illegal structural additions (αυθαίρετες κατασκευές) may be present on the property at the time of registration.

7. Booking Platform Requirements

Greece's Law 5021/2023 and its implementing ministerial decisions impose direct obligations on booking platforms operating in the country. Airbnb, Vrbo, and Booking.com are not passive intermediaries under Greek law; they carry active compliance duties that affect every listing in Athens.

Verification Requirements

• Platforms must confirm a host's AADE registration number and short-term rental registration (AMA) before activating a listing for bookings.

• Listings without a valid AMA displayed in the listing header cannot be processed for new reservations.

• Platforms are required to cross-reference submitted registration numbers against the AADE digital registry in real time.

Reporting Requirements

• Platforms must submit quarterly transaction reports to AADE, covering gross rental income per host, number of nights booked, and guest nationality data.

• Failure to submit accurate reports exposes platforms to fines starting at €10,000 per reporting period under Article 58 of Law 5021/2023.

• Host-level discrepancies between platform-reported income and individual tax filings trigger automatic audit flags.

Greece's STR framework under AADE (tax authority) does not include a specific statute making it illegal to advertise a short-term rental property before a booking transaction occurs. The existing rules govern registration, tax declaration, and operational compliance, not the act of advertising itself.

Listing an unregistered property carries penalties, but those attach to the operation and income reporting, not to the advertisement appearing on Airbnb or any other channel. Because no STR-specific advertising prohibition exists under Greek law as of May 2026, this section does not apply to Athens hosts.

8. Enforcement and Penalties

Civil Penalties

Athens-Clarke County enforces short-term rental violations under the Unified Development Ordinance and the county's business license code. Fines are per-violation, not per-day, but each new booking on an unlicensed property can constitute a separate violation.

• Operating without registration: Up to $1,000 per violation (ACC Code § 6-4-5)

• Exceeding occupancy limits: Up to $500 per incident

• Failure to collect or remit hotel-motel tax: Up to $2,500 plus back taxes owed, per Georgia DOR guidelines

• Zoning non-compliance: Up to $1,000 per violation under UDO § 9-25-4

Enforcement Mechanisms

• Platform verification: The county cross-references active Airbnb and Vrbo listings against the registered STR database quarterly

• Complaint response: Neighbor or guest complaints trigger inspections within 10 business days

• Proactive monitoring: Code enforcement uses third-party scraping tools to identify unregistered listings by address

• On-site inspections: Fire marshal and code officers conduct unannounced visits following a verified complaint

Registration Denial and Revocation

The Planning Department can deny or revoke a registration on the following grounds:

• Three or more substantiated noise or nuisance complaints within 12 months

• Misrepresentation of property type or ownership on the application

• Outstanding code violations or unpaid fines at the subject property

• Zoning non-conformance discovered post-issuance

9. Special Considerations

Rent-Regulated and Social Housing Units

Athens has a significant stock of rent-controlled properties, and hosting on Airbnb in these units is effectively prohibited.

Greek rent regulation law ties tenancy rights to primary residential use, and converting a rent-controlled unit to short-term use, even partially, constitutes a breach of the rental agreement.

• Lease clauses typically restrict subletting and any commercial use of the premises

• Landlord consent doesn't override municipal rent-control provisions

• Tenants caught hosting face eviction and potential liability for unpaid taxes on undeclared income

The consequence isn't a fine you can absorb. It's a lease termination and a civil claim from the landlord.

Historic Properties and Listed Buildings

Athens contains dozens of buildings under the Greek Ministry of Culture protection, particularly in Plaka and Monastiraki. Listed building status imposes additional restrictions on interior modifications, which affect everything from fire safety upgrades to accessibility installations that STR licensing may require.

• Fire door installations or emergency lighting may need cultural heritage approval before work begins

• Standard STR compliance requirements (smoke detectors, egress signage) can conflict with preservation rules

• Renovation permits take 6-18 months longer in protected zones

You can still register a historic property as an STR. Getting it to pass inspection is the harder part.

Mixed-Use Residential Buildings

Most Athens apartment blocks operate under a building co-ownership agreement (kanonismos). If that agreement explicitly bans commercial activity or short-term rental, your STR registration won't override it.

A majority vote of co-owners (typically 51% or more) is required to amend the kanonismos, and neighbors opposed to STR activity have successfully blocked registrations through this route.

10. Exemptions From Athens Short-term Rental Rules

Not every rental arrangement in Athens falls under the short-term rental registration framework; several categories operate under entirely separate regimes or sit outside the rules altogether.

• Stays of 90 consecutive days or more: These are classified as standard residential tenancies under Greek civil law and are governed by long-term lease legislation, not the Airbnb rules that Athens hosts must follow for short stays.

• Licensed hotels and serviced apartments: Properties operating under an official EOT (Greek National Tourism Organisation) hotel licence are regulated separately and are not required to hold an STR registration number.

• Registered bed-and-breakfasts: B&Bs with their own EOT category licence fall outside the short-term rental registration system.

• Student housing and dormitories: Purpose-built student accommodation managed by universities or accredited providers is exempt from STR licensing requirements.

11. Legislative Developments

Athens' short-term rental framework has been relatively stable since Greece's core STR registration law (AADE registry system) took effect. No major pending bills targeting Athens specifically were active in the Greek Parliament as of May 2026.

The most recent enacted change came through Joint Ministerial Decision 1188/2023, which tightened the income declaration requirements for STR operators and introduced stricter penalties for unregistered listings.

Greek municipalities, including Athens, have been pushing the central government for authority to cap STR density at the neighborhood level, a reform that has stalled twice in committee since 2024.

If that authority passes, hosts in Koukaki, Monastiraki, and Plaka should expect the first restrictions. No enacted version of that reform exists as of the current date.

Watch the Ministry of Tourism's legislative calendar; municipal-level caps are the likeliest next move.
