Athens Enforces Strict Rental Rules Starting September; Other Cities Get Lighter Guidelines

The Hellenic Parliament passed the Tourism Sustainability Bill in June 2026, requiring Athens hosts to register every short-term rental unit with the municipality and observe a 90-day annual limit in designated central zones.

Why the change arrives now

National tourism revenue reached 21.8 billion euros in 2025 according to the Ministry of Tourism annual report, with Athens accounting for 38 percent of that total through platforms operating in neighborhoods such as Plaka and Exarcheia. The legislation responds to pressure on housing stock documented in the 2026 National Budget Paper, which earmarked 85 million euros for municipal enforcement teams.

Athens residents renting apartments near Syntagma Square will see hosts required to obtain a municipal license number displayed in every listing, a step not imposed on hosts in Thessaloniki under the same bill. Local transport workers note that reduced availability of weekly lets could shift demand toward longer-term leases in outer districts like Kypseli.

Budget figures and resident costs

The bill directs 120 million euros from the 2026 central government allocation to Athens city hall for inspections and data sharing with booking platforms. Property analysts tracking the Athens real estate registry report that 42,000 units currently listed for short-term use will fall under the new caps, compared with an estimated 9,000 units in Thessaloniki that remain exempt from the day limit.

Households in Athens seeking year-round rentals may encounter fewer competing listings after the September start date, while small business operators near the Acropolis face potential reductions in peak-season foot traffic previously generated by short-stay visitors. The Ministry of Digital Governance will publish the first compliance data in October 2026.

Enforcement begins with a three-month grace period for existing hosts to complete registration, followed by fines scaled to the number of unlicensed nights reported through platform data feeds.
