Planning Law in Greece: Building Permit Revision vs Regularization
Legal frameworks, Law 4495/2017 procedures, notarial impacts & penalties
In Greece, planning law, buying, renovating, or constructing real estate requires a precise understanding of the legal and urban planning framework established by the Ministry of Environment and Energy (YPEN) and the Technical Chamber of Greece (TEE). Two fundamental procedures frequently arise during real estate audits and construction management: a building permit revision (Αναθεώρηση Οικοδομικής Άδειας) and the legalization or regularization of unauthorized constructions (Νομιμοποίηση / Τακτοποίηση Αυθαιρέτων).
Although both mechanisms ultimately lead to administrative compliance, their legal foundations, eligibility requirements, associated costs, and processing timelines are fundamentally distinct. Confusing the two can lead to severe financial penalties, immediate demolition orders, and insurmountable notarial blocks during real estate transactions.

Procedure: Permit Revision
Applied during active construction to adapt an existing permit before works reach full completion.

Procedure: Regularization (Law 4495)
Applied to built structures executed either without a prior permit or beyond the approved plans.

2. Legal, Notarial & Financial Implications
1. Notarial Conveyance & Electronic Building Identity (ITK): Under Greek real estate law, no transfer deed (purchase, sale, donation, parental grant) or mortgage can be validly executed without a licensed Civil Engineer’s Certificate (Βεβαίωση Μηχανικού) registered in the national Electronic Building Identity system (Ηλεκτρονική Ταυτότητα Κτιρίου – ITK). Any unregularized architectural deviation renders the deed null and void by operation of law.
2. Public Utility Connections (DEDDIE, EYDAP): Establishing permanent connections to the electrical power grid or water supply network requires formal certification issued by the municipal planning office (YDOM) or an official certificate confirming that at least 30% of the statutory fine under Law 4495 has been paid.
3. Site Inspections & Criminal Liability: Commencing unauthorized modifications on an active construction site without prior permit revision triggers an immediate work-stop order (Διακοπή Εργασιών), heavy building and annual maintenance fines, and potential criminal misdemeanor charges against both the property owner and the supervising engineer.
