Do not commit without professional review

Multiple high-priority signals were found in public data. Get explicit written input from a lawyer and engineer before any payment, travel, or contract.

Public geospatial data found at least one high-severity signal in the tested layers. Treat this as a priority item for professional review, not a recommendation to buy or not buy.

Needs attention5

What it means
Forest maps matter legally in Greece. A lawyer and engineer must verify. Automation does not prove title or permits.
What was found
The confirmed parcel intersects 101 forest-map polygon(s) from the imported regional dataset for Attica. Forest-law class code(s): Δ, ΑΝ, ΠΔ, ΔΔ, ΑΔ, ΔΑ. Other codes also present: Α, ΠΑ, ΑΑ.
What stays unknown
The result may be affected by location precision, boundary geometry, or partial data coverage. Treat as indicative, not definitive. Forest map status (posted, partially certified, final) is not encoded in the polygon. The classification can still be contested in official channels.
Source limit
Polygon context only. Forest-map legal status (posted, certified, contested) is not encoded and must be verified professionally.
Ask next
Ask a lawyer and civil engineer to verify official forest-map status and restrictions against the exact property footprint.

Public-data signal: Mapped overlapHow clearly the source answered: Indicative resultWho should verify: Lawyer / notary · Civil engineerForest-map region: Attica

What it means
National designations (CDDA) are separate from Natura 2000. Verify permit and use implications with professionals.
What was found
The parcel intersects a nationally designated protected area in the CDDA public dataset (national parks, aesthetic forests, wildlife refuges, and similar designations). Mapped site name: Parnitha.
What stays unknown
The source responded and the spatial check ran cleanly. The result still depends on whether the selected location matches the property being sold. CDDA polygons show national designations in public data. They do not replace Natura checks or local planning rules.
Source limit
National designations in public data, separate from Natura 2000 and does not replace local planning or permit checks.
Ask next
Ask the lawyer and civil engineer whether this designation affects building, renovation, access, or use of the exact property.

Public-data signal: Mapped overlapHow clearly the source answered: Check completedWho should verify: Lawyer / notary · Civil engineer

What it means
Environmental rules may apply. This does not prove permits or allowed use.
What was found
The confirmed parcel intersects Natura 2000 protected-site polygon(s). Site code sample: GR3000001. Site type sample: SCISPA.
What stays unknown
The source responded and the spatial check ran cleanly. The result still depends on whether the selected location matches the property being sold. Natura 2000 polygons mark mapped designations. They do not capture all environmental restrictions, buffer zones, or pending designations.
Source limit
Mapped protected-area context, not permit status, buffer rules, or full environmental compliance.
Ask next
Ask a lawyer and civil engineer whether the exact property footprint is affected by Natura 2000 restrictions, environmental approvals, or related planning constraints.

Public-data signal: Mapped overlapHow clearly the source answered: Check completedWho should verify: Lawyer / notary · Civil engineerNearby site code: GR3000001

What it means
These are past observed flood events on record, separate from the zone maps above. Ask an engineer and insurer about the property’s actual history.
What was found
Public YPEN historic flood event data records 16 observed event(s) within about 10 km of the parcel. Example mapped event name: Δημοτική Κοινότητα Άνω Λιοσίων.
What stays unknown
The source responded and the spatial check ran cleanly. The result still depends on whether the selected location matches the property being sold. Historic PFRA points come from a national assessment snapshot. They do not capture every local flood or future drainage changes.
Source limit
Recorded past events from a national PFRA snapshot, not a forecast, not insurance proof, and separate from the official flood hazard/risk zone layers checked above.
Ask next
Ask a civil engineer and, where relevant, an insurance broker whether historic flooding, drainage, basement use, or local runoff affects the exact property or street.

Public-data signal: Nearby, no interior overlapHow clearly the source answered: Check completedWho should verify: Civil engineer · Lawyer / notary

What it means
Mapped fault proximity is indicative context only, not an official ΕΑΚ seismic class or building safety rating.
What was found
Public NOAFAULTs mapping suggests the nearest mapped active fault line (Katsimidi fault (GR0621)) crosses or touches the confirmed parcel. Catalog metadata lists kinematics: Normal; catalog activity reliability: possible.
What stays unknown
The result may be affected by location precision, boundary geometry, or partial data coverage. Treat as indicative, not definitive. NOAFAULTs maps catalogued active fault lines, not official ΕΑΚ seismic zones, soil conditions, or structural safety of a building.
Source limit
Mapped fault-line proximity only, not an official ΕΑΚ seismic design category, building safety rating, or site-specific geotechnical assessment.
Ask next
Ask a civil engineer to verify official ΕΑΚ seismic design category, local geology, and structural condition for the exact building or plot.

Next steps with your professionals

Questions to copy into an email, grouped by who should answer them.

Lawyer / notary6

  1. 1Please verify the official cadastral sheet, cadastral diagram, title position, encumbrances, and whether the public parcel context matches the property being sold.
  2. 2Please confirm whether mapped flood hazard/risk context affects disclosure, insurance, financing, or intended use.
  3. 3Please confirm whether the property is inside or near Natura 2000 or other environmental designations shown in public geospatial data.
  4. 4Please verify forest-map status (posted, partially certified, or final) through official Hellenic Cadastre tools and confirm any forest-related restrictions.
  5. 5Please confirm whether official planning, settlement-boundary, archaeology, coastal/foreshore, or cultural-heritage restrictions affect the exact property or planned use.
  6. 6Please confirm whether legal access, easements, shared roads, utility rights, or connection obligations are documented in the title and contract file.

Civil engineer6

  1. 1Please confirm whether the public parcel polygon aligns with the built footprint, access, and any pending cadastral corrections.
  2. 2Please verify whether the exact property footprint and any basement/semi-basement areas are affected by flood hazard/risk mapping or local drainage issues.
  3. 3Please confirm whether Natura 2000 context affects permits, renovation scope, or intended use.
  4. 4Please confirm whether forest-map context affects permits, renovation scope, buildability, or intended use.
  5. 5Please assess water, electricity, sewage, road access, slope, retaining-wall, and drainage constraints on site, including likely connection or upgrade works.
  6. 6Please verify official EAK seismic-zone context, site geology, and whether structural or geotechnical review is needed for purchase, renovation, or insurance.

Accountant / tax adviser2

  1. 1Please confirm short-term rental or investment tax reporting obligations and local levy requirements if applicable.
  2. 2Please confirm ENFIA, municipal fees, declared area, rental-income reporting, and whether the intended use creates VAT or business-registration obligations.

  3. 3Please assess whether practical guest access, parking, public transport, utilities, seasonality, and local services support the intended rental use.

Limitations

Public pre-check, not legal or technical certification

This report is a public-geospatial-data pre-check of the location you selected. It is not legal, engineering, tax, or insurance due diligence and does not replace a lawyer, engineer, notary, accountant, insurer, or official authority.

It does not certify or verify ownership, contract status, permits, safety, buildability, compliance, or short-term rental approval.

Absence of a signal in tested layers does not prove absence of risk. Items not checked automatically require professional verification.
