When a stone house in Kynouria is bought so that strangers may sleep there for a few nights at a time, the deed is the first paper and not the last: the Hellenic Cadastre, the national registry of plots and rights, must name a proprietor on the current sheet; the room must meet the specifications that have bound a short stay since the first of October 2025; the Independent Authority for Public Revenue, the national tax authority, must accept the property on the register it keeps of such lettings; and every public listing must show the number that register issued. A photograph that already prices the first season is none of those papers.
A house that cannot be shown on a current cadastre sheet is a house that cannot lawfully be put on a register.
The papers are a copy of the sheet — who is named, in what share, what burdens sit on the property — and an extract of the diagram, the map of this plot on its street or hillside, with the number the Cadastre uses for that unit. Both are issued remotely with tax-office codes, through the official registry of procedures, and that map must travel with every later application to register a new act. The sheet copy is €9.50, plus €4.50 for each extra sheet; the diagram extract is €15; the digital estimate, on the pages as they stood on 19 August 2026, is six days. The wrong number produces a certificate for a different property, and the application cannot be cancelled or rewritten.
If the proprietor field reads unknown owner, the first registration did not name a proprietor. Until that line is corrected, what would be let is a possession story, not a registered title. From 16 September 2026, before a court will hear a claim of ownership by twenty years of possession on a sheet that names no one, the law requires a first cadastral mediation session. That file is separate. It is not restated here.
Use is a paper. Residential, restorable, inside the settlement — those are broker words. No official text is restated here that would settle the permitted use of a named plot in Leonidio. A building permit and the current planning status of that plot, including the planning zone that says what may be built there, are papers. The listing does not contain them.
Until the house the system names is the house that is intended to be let, the later statuses are speculation.
Since the first of October 2025 the specifications have been in force. They sit on the property that is let as a short stay under the tax statute. The space must be a main-use room. It must have natural light, ventilation and cooling. It must carry civil-liability insurance for damage or accident. It must have an electrician's declaration, extinguishers, smoke detectors, a residual-current device and escape signage. It must have a pest-control certificate, a first-aid kit and a guide with emergency numbers.
Compliance is checked on site. Officials of the Tourism Ministry may inspect the space declared on the tax authority's platform. Mixed teams with the tax authority may inspect at the same time. At least ten days' notice precedes the visit, so that the manager can produce the papers. The inspectors carry an identity card and a written order.
The fine is five thousand euros, imposed on the manager, if entry is refused, if any specification is missing, or if the follow-up duties after a first finding are not met. If a new inspection within a year of the first fine finds the same specifications still missing, the fine doubles. Each later finding of the same kind multiplies the original amount by four.
The short-stay path the official texts describe is a room that meets the list and a register that has accepted the property. A tourism operating mark belongs to a different file. So does a guesthouse permit for a traditional building.
If the model that was brought is a guesthouse — breakfast, daily cleaning, a reception, a sign on the lane — the short-stay definition has already been left. Extra services beyond linen take the property into tourism accommodation. Then a business must be opened with the tax authority, and a tourism notification must be filed. That statement sits on the authority's own questions-and-answers of 10 July 2025. Official steps for a guesthouse in a traditional building, and for any tourism-spatial class assigned to Leonidio, are not set out here. The services that are actually offered choose the file. The photograph does not.
The tax file is the one investors treat as the whole of licence, because it produces a number they can paste into a listing. The number is a tax paper. It is not a licence, and it is not a first registration.
On the pages as they stood on 19 August 2026 the authority is spare. As owner, the property may be let as a short stay through digital platforms. The duties then are closed. The property is registered on the short-stay register and a registry number is obtained. That number is shown on every platform and every other means of promotion. A stay declaration is filed for each stay. The register is finalised by 28 February, and the income is declared on the property-rents schedule and the income-tax return.
The stay declaration is due by the twentieth of the month after the guest leaves, and may be amended until 28 February of the income-tax year, before the register is finalised. If a cancelled booking still produces a rent, an initial stay declaration is due by the twentieth of the month after the cancellation.
Since the first of January 2024 the definition no longer depends on a platform. A short stay is a letting or subletting of fifty-nine days or fewer, of a furnished property, with no service beyond linen. Fifty-nine days is the length of each stay, not a yearly cap. A letting of sixty days or more is a long let, and it uses the ordinary property-lease information return. A room let separately inside a house needs its own number. Off-platform stays of fifty-nine days or fewer still go on the register.
Income is property income when a natural person lets no more than two such properties. It is business income when a natural person lets three or more, and when a company lets any number. Value-added tax follows the same line: exempt for a natural person with up to two properties; thirteen per cent for a natural person with three or more, and for every company. The third registration is what starts the business file, even if two of the properties never produce a night.
A climate-resilience fee is due on every short stay: two euros a day from November through March and eight from April through October, on the official questions-and-answers. Foreign owners who take this income need a Greek tax number.
For a house in Leonidio, or elsewhere in South Kynouria, the local tax office that still holds subject-matter and territorial competence is the tax office of Tripolis (A), in Tripoli. It is the office that absorbed the former tax office of Leonidio. A registration, a stay declaration and a question about this income go there, not to a counter that closed when the local office was folded in.
None of this is a planning permission. A clean tax register on a house the cadastre does not name, or on a room that fails the October 2025 list, is a number sitting on the wrong file.
The number must appear, visibly, on every listing and on every other means of promotion. One number covers the same property on two platforms; separate rooms need separate numbers. Operating without the number is a tax offence wherever the house sits. The official consolidation the tax authority publishes sets a fine of half the year's gross short-stay receipts, and not less than five thousand euros, for a manager who lets without the register or without showing the number, with fifteen days to comply after the finding; a repeat within a year doubles the first fine. A missing or inaccurate stay declaration is fined at twice the rent shown on the platform that day; a late declaration is one hundred euros, unless the income has already gone into that year's return.
That is the nationwide rule. A 2026 statute separately bans first-time registration on the short-stay register in the first, second and third municipal districts of Athens, and in the first municipal community of Thessaloniki from the first of July to the thirty-first of December 2026. Transfers between living persons in those areas delete the registration for as long as the ban lasts; letting there without a lawful first registration is fined at half the short-stay income, and not less than twenty thousand euros, and a repeat in the same tax year is the whole of those rents, and not less than forty thousand.
Leonidio sits outside those districts. A first registration can still be filed here. Whether the house can then carry a lawful stay depends on the sheet, the room and the register.
The remaining point is the model that is actually run. Lodging and linen keep the house on the short-stay path the official pages describe. Breakfast, daily cleaning, a reception, a sign on the lane have already left that path, and the official steps for a guesthouse in this town are a file that is not opened here. A number on a listing will not walk them back.
