The demolition and construction permit concerns property owners who wish to demolish an old building and construct a new, modern, and safe one in its place.
These are two separate permits, both issued through the electronic e-Permits (e-Άδειες) system, and they require the collaboration of engineers from different disciplines.
What is a Demolition Permit
A demolition permit is the official administrative act that allows the removal of an existing building.
It is required:
- for the complete demolition of a building,
- for partial demolition (e.g., a floor or roof),
- or for preparatory works before new construction.
The process ensures that demolition is carried out legally and safely, without endangering neighboring buildings or passers-by.
Required Documents for a Demolition Permit
To issue a demolition permit, the following are required:
- Property titles and registration certificate
- Cadastral map extract
- Certificate of plot suitability and buildability
- Topographic survey based on the Greek Grid (EGSA ’87)
- Assignment and undertaking declarations for study/supervision
- Demolition plan (describing the method, machinery, and safety measures)
- Approval from DEDDIE/ΕYDAP (if there are utility connections)
- Approval or consent from competent authorities (e.g., Archaeology, Forestry, Ministry of Culture) where applicable
💡 In cases of fire-damaged or earthquake-damaged buildings, the demolition permit is issued through a special compensation procedure by the Ministry of Infrastructure.
Duration of the Process
The issuance of a demolition permit usually takes 1–2 weeks, depending on the completeness of the documentation.
Work can begin 20 days after the permit’s publication online, as stipulated by Law 4495/2017.
What is a Building Permit
A building permit (also called construction permit) is the next stage: it grants the owner the right to build a new structure.
It includes the approval of all technical studies and ensures compliance with current urban planning and energy regulations.
Steps for Issuing a Building Permit
- Preliminary study and topographic verification
- Preparation of architectural, structural, and electromechanical studies
- Approval of building terms by the Urban Planning Authority (ΥΔΟΜ)
- Submission of the application through the e-Permits system
- Payment of professional fees and contributions (TEE, EFKA, IKA, engineer taxes)
- Issuance of the electronic building permit
- Commencement of construction with appointed supervising engineers
Required Studies
For a new building permit, the following studies are required:
- Architectural study
- Structural (static) study – and static adequacy of existing structures where applicable
- Electromechanical installations study
- Energy performance study (KENAK)
- Fire safety study (where required)
- Thermal insulation, drainage, water supply, and lighting studies
When Both Permits Are Required
- When an old or unsafe building is replaced with a new one
- In fire-damaged or earthquake-damaged properties requiring reconstruction
- For large-scale renovations that include full demolition
- When the use or structural requirements of a plot change
Cost of Demolition and Construction Permits
The total cost depends on:
- The area and location of the property
- The number and complexity of required studies
- Engineers’ professional fees
- Public contributions and insurance funds (TEE, EFKA, etc.)
- Whether a simple or reinforced foundation is required
Indicative range:
- Demolition permit: from €300–800 (for small houses)
- Building permit: from €1,500–3,500, depending on project scope
(Exact costs vary based on project type, size, and study requirements.)
Which Engineers Are Involved
The process requires the collaboration of a civil engineer, architect, and often an electrical engineer.
Katsouris Engineering manages the entire procedure end-to-end, including:
- Surveying the existing structure (3D Laser Scanning)
- Preparing all studies
- Submitting and managing the e-Permits file
- Supervising construction on-site
Example in Practice
In the reconstruction of a fire-damaged residence in Mati, the Katsouris Engineering team undertook:
- Demolition of the damaged shell
- Structural design of the new load-bearing system
- Issuance of the building permit
- Full supervision until completion
The project was delivered with modern energy efficiency and seismic protection standards.
Frequently Asked Questions
How long is a demolition permit valid?
It is valid for one year, with the option of renewal if the demolition is not completed.
Can I demolish without a permit?
No. Even small demolitions (walls, roofs, etc.) require either a small-scale works approval or a demolition permit, depending on the case.
What if the building is listed or preserved?
Special approval from the Ministry of Culture or the Architectural Council is required before any intervention.
The demolition and construction permit forms the foundation for any reconstruction or new building project.
Proper preparation and guidance by an experienced engineering team save time, money, and prevent bureaucratic delays.
