The engineer’s technical report is a central document in an EUR 250,000 Greece Golden Visa commercial-to-residential conversion project. It is not a general property survey and it is not simply a description of renovation quality. Its purpose is to connect the purchased property, the planning record and the completed change of use in a form that supports the official residence-permit procedure.
For a buyer, the report is valuable because it turns a broad commercial claim into a property-specific technical statement. It should identify the legal act behind the conversion, the previous and new uses, the relevant property and deed, and any additional facts required by the type of building.
What the official procedure requires
The Greek National Registry of Administrative Public Services lists a technical report by an engineer among the documents for the change-of-use Golden Visa procedure. The report must confirm the conversion of the main spaces to residential use and identify how that conversion is evidenced.
The official wording refers to the review of the building permit, approval of small-scale construction works, update of the file, revision of the building permit or another relevant act. The report should specify which act applies. It must also connect the conversion to the property transferred in full ownership and possession to the investor under the identified notarial deed.
The report should identify the exact property
Project names and marketing codes help buyers navigate a portfolio, but the technical report must rely on legal property identifiers. The engineer should be able to match the report to the deed, cadastral information and planning file. In a building containing several units, this is particularly important: the report should not leave uncertainty about which main spaces were converted and which property was acquired.
Before completion, compare the property description across the engineer’s report, title documents, deed and land-registry evidence. Floor, unit designation, boundaries, areas and cadastral references should be internally consistent or clearly reconciled by the professionals responsible for the file.
How the conversion should be evidenced
A robust report explains the documentary path rather than relying on appearance. A finished kitchen and bedroom do not by themselves prove a legal residential use. The engineer should review the applicable planning records and state the act through which the file was updated, revised or otherwise brought into the qualifying residential-use position.
The timing matters as well. The official procedure requires the qualifying change of use to be completed after 5 April 2024 and before the Golden Visa application. If an earlier permit existed, the official guidance requires an update or revision of the specific file after the new law’s publication. The report should make that chronology understandable.
Additional rules for industrial buildings
Where the property is an industrial building, part of one, or located in a property containing an industrial building, the procedure adds another technical issue. The engineer must certify that no industrial activity has been installed and operating there for at least the previous five years.
The official page lists examples of evidence that may support this statement, including an electricity-disconnection certificate from HEDNO or the municipality, E2 tax forms covering the previous five years, or a combined review of documents issued by tax or other public authorities. The correct evidence depends on the property history and should be reviewed before the transaction timetable is fixed.
The procedure also contains specific wording for projects created through interventions, vertical additions, extensions to industrial buildings or new independent buildings on plots where an industrial building is located. In those cases, the report must describe the qualifying physical and cadastral relationship with particular care.
Technical due-diligence questions for buyers
A buyer reviewing a Greece Golden Visa conversion project should ask the engineer or legal team several focused questions:
- What was the legally recorded use before the conversion?
- Which permit, approval, file update or revision establishes the residential use?
- When was the relevant act completed?
- Does the report identify the same property and investor as the deed?
- Are the main spaces, areas and cadastral references consistent?
- Does an industrial-building rule apply?
- If it applies, which five-year records support the absence of industrial activity?
- Will the final signed report be available before the residence-permit application?
What the report does not replace
The engineer’s report does not replace legal title review, the notarial certificate, proof of payment, land-registry evidence, the investor’s E9 declaration or the applicant documents required by the immigration procedure. These records perform different functions. The strongest file is one in which the technical, legal, financial and immigration documents all describe the same transaction.
It also should not be treated as a guarantee about an applicant’s personal eligibility or a substitute for independent advice. Its role is narrower and more useful: to certify the technical facts required for the property route.
Building the report into the project timetable
The report should not be left until the final day before filing. A developer-led workflow should allow time for the engineer to review the complete planning file, resolve discrepancies, inspect the relevant spaces, obtain any special industrial-building records and coordinate references with the notary and lawyer.
Where a document is missing, the project team needs enough time to obtain it from the relevant authority or correct the file. This is why a conversion project should be assessed through a document schedule as well as a construction schedule.
