Property Due Diligence in Greece Permits, ΗΤΚ and Legal Status
Before you sign, compare the title information supplied to your lawyer, the permit records, approved drawings, Electronic Building Identity and the building itself. Premier Construction gives foreign buyers, owners abroad, investors and landlords an engineer-led review with English reporting and remote coordination.
What we check: permit verification and ΗΤΚ
Our review follows an evidence chain: document received, approved information, observed condition, mismatch, possible consequence and next action. It is a technical due diligence service, not a promise that a property is legally clear.
| Review area | What we compare |
|---|---|
| Permit file | Known permit number, revisions, updates and drawings that can be obtained or supplied. |
| Approved versus actual | Areas, layout, uses, visible elements and evidence from documents or inspection. |
| Unauthorised works | Potential mismatches that need current engineer assessment and supporting evidence. |
| Electronic Building Identity | Register status, extract and completeness information relevant to the transaction. |
| Missing evidence | Questions and documents needed before a buyer, seller or project team decides. |
Use the Checklist to separate the documents already available from the gaps that need follow-up.

This checklist is indicative. An engineer confirms what is required for the specific property or project.
Three decisions the review supports
- Before purchase: identify technical gaps before a buyer signs or releases a transaction milestone.
- Before sale: prepare the technical file and surface questions before the buyer’s review.
- Before renovation or finance: test whether the planned project starts from a documented baseline.
Engineer, lawyer and tax adviser
A lawyer reviews title, ownership, encumbrances and contract matters. An engineer reviews the built condition, permits, plans and technical records. A tax adviser covers taxes. We coordinate with the client’s advisers in English, but we do not replace their advice.
From file intake to decision call
- Intake: confirm the property location, transaction stage, known permit number, available plans and decision date.
- Document request: send a structured list to the owner, seller, lawyer, notary or property manager.
- Remote review: compare permits, drawings, ΗΤΚ information, photographs and video walkthrough evidence.
- Site inspection where available: add a visit only when it can be arranged for the specific location and agreed scope.
- Engineer report: record red, amber and green findings, source documents, discrepancies and limitations.
- Decision call: explain open questions, remediation routes and what another adviser needs to confirm.
Unauthorised works and regularisation
A mismatch is a finding, not an automatic answer. Date, category, evidence, property position, use and planning restrictions can affect whether a declaration or legalisation route is available. We do not describe unauthorised works as legalisable before the engineer checks the complete file.
For context, see our guides to legalising unauthorised constructions and building permit verification.
Electronic Building Identity before transfer
The ΗΤΚ is entered in the TEE electronic register by an authorised engineer. The relevant extract or completeness certificate for a transaction depends on the current rules and the property’s file. We check the status, identify missing evidence and coordinate questions with the client’s legal team.
Read the Electronic Building Identity guide for background.
What the client receives
- A register of documents received, requested and still missing.
- A comparison of available permits, approved drawings and measured evidence.
- Red, amber and green findings with a source or limitation.
- Unresolved questions and a recommended next action.
- A clear boundary between technical findings and legal, tax or notarial advice.
- English reporting and coordination with the client’s lawyer, notary or property manager.
Fixed-scope packages can be arranged around a document-gap review, a fuller technical due diligence report or follow-through into renovation planning. The package is agreed after the property and evidence are understood, without a generic price or fixed legal outcome. Meet the engineering team responsible for the technical review.
Remote oversight for owners abroad
Secure file exchange and video walkthroughs can begin the review before you travel. A written report keeps the evidence and open questions in one place, while a decision call helps you brief your lawyer, notary, seller or project team. If the property later needs work, we can connect the findings to renovation after due diligence.
Location coverage and any on-site arrangement are confirmed for the individual instruction. We do not publish an Athens, Mykonos or island case example without evidence and permission.

This guide is general information, not legal, tax or notarial advice. An engineer confirms the position for the specific property and the relevant adviser confirms the transaction document requirements.
Correction policy: if the legal framework changes, the relevant section is reviewed and dated again.
Questions from foreign buyers and owners
How do I verify a building permit in Greece?
An engineer compares the permit number and file, approved drawings, available Electronic Building Identity records and the actual property. The review starts with the documents supplied by the owner or seller and identifies what can be checked, what is missing and what needs a site inspection.
What should a foreign buyer check before buying property in Greece?
Ask a lawyer to review title, ownership and encumbrances, and an engineer to review permits, approved plans, areas, uses, ΗΤΚ and unauthorised works. A tax adviser covers the tax position. These reviews support one transaction but they are different professional scopes.
What is the Electronic Building Identity in Greece?
The Electronic Building Identity is a digital record entered by an authorised engineer in the TEE register for a building or property. The extract and any completeness certificate required for a transaction depend on the current rules and the specific case. The engineer confirms the document route.
Can unauthorised building works be legalised in Greece?
Some cases may be capable of inclusion in the applicable framework, but eligibility is not automatic. Date, category, evidence, location, use and restrictions all matter. A current engineer assessment is required before a regularisation declaration or a legalisation permit is selected.
Can you check a Greek property remotely before I travel?
Yes, the first stage can be a secure document review, a missing-information list and a video walkthrough. If an on-site inspection can be arranged for the location, it is added to the agreed scope. Remote project oversight reports the evidence, open questions and next decision.
Need a permit or property file reviewed?
Send the property location, known permit number, transaction stage and the drawings or records you have.
