The deadline for issuing the Building Identity Certificate for certain property categories is approaching. According to the Ministry of Environment and Energy, as of January 31, 2026, owners who have not completed the process may face fines ranging from €200 up to 10 % of the property’s objective value.
If you own a tourist accommodation, educational facility, hospital, fuel station, or any building open to the public, obtaining the certificate is now mandatory.
For all other properties, the Building Identity Certificate is required for every sale, donation, inheritance, or legalization of unauthorized constructions.
In the following guide, you will learn who is required to obtain it, which documents are needed, and how to complete the process properly and without delays.
What Is the Building Identity Certificate
The Building Identity Certificate is the digital record of each property, confirming its legal status. Through the official TEE (Technical Chamber of Greece) platform (web.tee.gr):
- Building permit and architectural drawings
- Energy Performance Certificate (EPC)
- Declarations of building legalization
- Structural adequacy study or technical report
- Floor-area distribution tables and other legal documentation
The process is carried out exclusively by a licensed engineer, who submits the data and issues the Certificate of Building Completeness.
Who Is Obliged to Obtain It
Since February 1, 2021, the Building Identity Certificate has been mandatory for all private and public buildings (Ministry of Environment and Energy). However, the following categories must obtain it by January 31, 2026:
- Tourist accommodations over 300 m²
- Schools and childcare facilities
- Hospitals and healthcare centers
- Public-assembly buildings (theaters, cinemas, gyms, etc.)
- Fuel stations, car washes, and repair workshops
- Public buildings and municipal facilities
For all other buildings (residences, apartments, offices, etc.), the certificate is required whenever
- there is a sale, donation
- legalization of irregularities
- issuance of a new building permit
Deadline and Processing Time
The deadline for special building categories is January 31, 2026, as stated by the Ministry of Environment and Energy.
The time required depends on the completeness of each file. If all documents are available, the certificate can be issued within a few days. If new surveys or records from local authorities are needed, it may take a few weeks.
Fines for Delay or Non-Issuance
Failure to issue the Building Identity Certificate on time results in penalties imposed by the Special Secretariat for Environmental Inspection:
- Minimum fine: €200
- Maximum fine: Up to 10 % of the property’s objective value
The fines remain valid until the certificate is properly issued.

Documents Required by the Engineer
To proceed, your engineer will need:
- The original building permit with all revisions
- Updated architectural drawings and plans
- The Energy Performance Certificate (EPC)
- Structural adequacy study or technical report (if required)
- Legalization declarations for any unauthorized works
- Ownership allocation tables (for multi-unit buildings)
If some documents are missing, the engineer can issue a certificate of loss and create new digital drawings.
