Legalising unauthorised construction in Mykonos

In Greece, anything built without a permit, or differently from what the permit allows, is considered unauthorised: an enclosed veranda, an extension, a pool, a pergola or a change of use. On Mykonos, where many houses have grown bit by bit over the years, this is one of the most common issues we deal with.

Why it matters

Until it is legalised, the property cannot be sold, transferred to your children or mortgaged, and it cannot obtain an Electronic Building Identity. Most owners find out at the moment of sale, when time is short. If you are buying, ask for this check before you sign: it is far easier to deal with before the transfer than after.

How we work

  • On-site inspection and collection of the documents we need from you
  • Survey of the building as it stands and comparison with the permit
  • Calculation of the fine before you commit
  • Submission through the Technical Chamber of Greece online platform
  • Delivery of the complete legalisation file

Not everything can be legalised. The law excludes certain cases, such as construction on the foreshore or in protected areas. We will tell you clearly from the start, before you pay anything.

Frequently asked questions

Can I sell a house with unauthorised construction?

Not until it is legalised. A property transfer requires an engineer’s certificate confirming there is no unauthorised construction, or that it has been legalised.

How much does legalisation cost?

The fine depends on the type, size and age of the construction, the area and the value of the property. We give you an exact calculation after the inspection, before you commit.

No. The law excludes certain cases, such as construction on the foreshore or in protected areas. We will tell you clearly from the start.
