When Do You Need a Full Building Permit in Greece?
The Full Building Permit is necessary for major construction projects such as building a new house, extending an existing structure, or making structural changes that affect the stability of a building. This permit is also required for large-scale earthworks, excavation deeper than 0.8 meters, and the construction of swimming pools or retaining walls. To obtain a full permit, the applicant must submit a detailed dossier that includes architectural designs, structural calculations, energy efficiency studies, geotechnical reports if needed, and various technical plans.
These documents are reviewed by the local Building Service through the national electronic permitting platform, known as e-Άδειες. Once approved, the permit is typically valid for four years in residential cases and up to six years for more extensive projects. Processing time varies but generally takes up to 45 working days, provided all necessary documentation is complete and compliant with current legislation.
What Is a Small-Scale Building Permit and When Is It Used?
For less complex projects, a Small-Scale Building Permit is often sufficient. This applies to work that does not impact the building’s structural integrity or increase its volume. Common examples include interior renovations that do not alter load-bearing walls, facade repairs, and external painting, if scaffolding is needed, installation of pergolas or small garden structures, and upgrades such as thermal insulation or solar panels. Even relatively minor additions, such as small pools under 50 square meters or temporary construction site offices, may require this type of approval. The application process is simpler and faster than that of a full permit, but still requires submission through a licensed engineer who ensures all technical and legal standards are met. A Small-Scale Building Permit is typically valid for one year, with the possibility of renewal.
