Greece’s Parliament voted on 11 November 2026 for an energy ministry bill that also amends the Spatial Planning–Urban Planning Code (Law 5306/2026, ΦΕΚ Α’ 88/08.06.2026), including the rule on merging adjoining flats. The law is passed but not yet published in the Government Gazette.
The bill, “Improving the design of the electricity market”, was tabled on 31 October 2026 by the Ministry of Environment and Energy, according to the Hellenic Parliament. Parliament’s page lists it as voted on 11 November. It notes that the posted text is not final while spelling and syntax corrections are pending, so article numbers may change. The numbers below are those of the tabled bill.
Article 80 amends Article 220 of the Code on joining adjoining properties into one functional unit. The Code already allows this with the consent of owners holding at least 67%, provided the structure is shown to be adequate. The bill keeps the 67% threshold. It widens the rule from building plots to land parcels and drops the limit to “horizontal” units. The bill’s accompanying reports describe it as covering units on the same level that touch but sit in different buildings. A new paragraph 6 applies the rule to existing joined units that owners have approved in writing. We reported the change when the bill was tabled.
Two other planning changes in the tabled text:
- Municipal roads. Once a municipality’s road network has been recorded, it is to be ratified by presidential decree on the environment minister’s proposal, instead of by a decision of the secretary of the decentralised administration (Article 251(1) of the Code). This sits in Article 79, which corrects errors in the Code and, under Article 90, applies from 8 June 2026, the date the Code was published.
- Evros Delta. The deadline for the presidential decree on the protected Evros Delta moves from 31 December 2026 to 31 December 2027 (Article 411(4)). Until that decree is issued, sanctions on unauthorised structures there stay suspended and existing demolition orders stay frozen.
The same bill creates the island decarbonisation fund we covered last week.
What it means for buyers
The flat-merging change affects owners joining adjoining units, including units on the same level in neighbouring buildings and joins that already exist with written approval. The 67% consent threshold does not change. The road change concerns how municipal road networks are ratified, which matters for plots whose building rights depend on a recognised road. Buyers should confirm how this applies to them with a Greek lawyer or accountant.
What happens next
The law takes effect when it is published in the Government Gazette, unless an article sets another date. We will check the final text and article numbers then.
