How building permits work in Greece
Building permits in Greece are issued through the e-adeies digital platform managed by the Ministry of Environment and Energy. The process requires a licensed civil engineer or architect to prepare and certify the technical studies. The permit fee is calculated on the reference construction value (proypologismos), not necessarily the actual contract price. Engineer fees are negotiable but are guided by the Technical Chamber of Greece (TEE) minimum fee scales, which were mandatory until 2001 and remain a market benchmark.
Example calculation
Major renovation with a budget of 100,000 EUR. Engineer fees at 8%: 8,000 EUR. Permit fees at 0.75%: 750 EUR. EFKA contribution at 1%: 1,000 EUR. E-adeies system fee and miscellaneous: 500 EUR. Total permitting cost: approximately 10,250 EUR, or 10.25% of the construction budget. This cost is incurred before any construction work begins.
Tips and considerations
Engage an engineer with recent experience in the specific local planning authority, as permit processing times and requirements vary between municipalities. Always insist on seeing the completed building permit (adeias oikodomis) with the municipal seal before any construction starts. Paying contractors before the permit is issued creates legal and financial risk. Budget 10-15% of the construction cost for all pre-construction permitting, professional fees, and unforeseen regulatory requirements.
Frequently asked questions
How much does a building permit cost in Greece?
The total cost of obtaining a building permit in Greece depends on the size and value of the project. The main costs are: the civil or structural engineer's fees (typically 5-8% of the construction cost budget for architectural, structural, electrical, and plumbing study preparation), the building permit fee levied by the local planning service (typically 0.5-1% of the reference construction value), the electronic building permit system (e-adeies) fee, and the EFKA contribution on construction activity. A building permit for a 100,000 EUR construction project typically costs 8,000-12,000 EUR in total fees before construction begins.
What is the building permit process in Greece?
The Greek building permit process is managed through the e-adeies electronic system. The property owner engages a civil engineer or architect who prepares the architectural, structural, electromechanical, and thermal insulation studies. These are uploaded to the e-adeies portal along with proof of land ownership, topographic survey, and approval from the local urban planning service that the plot is buildable. The permit fee is calculated and paid electronically. For small works not requiring full permits, a Small-Scale Works Notification (Egkrisi Mikris Klimakos) can be filed instead. Processing times range from two weeks to several months depending on workload and whether objections are raised.
What happens if I build without a permit in Greece?
Unauthorised construction (authaireta) is a serious and widespread problem in Greece, with an estimated 1-2 million properties having some degree of illegal construction. Buildings or additions constructed without permits cannot be legally sold, mortgaged, or inherited without first going through the regularisation (legalization) process, which involves paying a fine based on the illegal surface area and construction date. Since 2011, successive amnesty programs have allowed partial regularisation for a fee, but fully illegal buildings without any original permit cannot be regularised under current law. Buyers should always verify the building permit status before purchasing.
Can I regularise an unauthorised extension or building in Greece?
Greece has operated several amnesty programs allowing partial regularisation of unauthorised construction for a fee. The most recent program under Law 4495/2017 (as amended) allows owners to declare and pay a fine for illegal construction completed before 2018, providing a temporary suspension of demolition orders and allowing the property to be sold or mortgaged. The regularisation fine depends on the size of the illegal construction, its use, and the date it was built. Regularisation does not make the construction permanently legal but suspends enforcement and allows property transactions to proceed. Full legalisation through a new building permit is only possible for construction that meets current planning rules.
