Short answer: yes. Adding a room, a floor, or any extra floor area to your house is “development” under the planning law, so it needs planning permission (Πολεοδομική Άδεια) and then a building permit (Άδεια Οικοδομής). An extension is never a no-permit job. (This is one of the works covered in our main guide. Do I need planning permission in Cyprus?)
New permit, or an addition to the existing one?
If your building was lawfully built and its planning permission is still valid, the application usually covers only the new extension; the already-approved part is shown on the drawings but not re-permitted. However, a new planning permission for the whole building is required where the extension (Εγχειρίδιο Πολεοδομικού Ελέγχου, 1st Rev. Jan. 2025, §3.3):
- materially alters the original building envelope;
- is large enough that the building coefficient (ΣΔ) must be recalculated for the whole development; or
- materially intensifies the use.
Your architect works out which of these applies before choosing the form of application.
The constraints that decide how big you can go
An extension isn’t just “fill the garden.” Three limits bite:
- Building coefficient (ΣΔ) and coverage: the extra floor area must fit within the plot’s remaining ΣΔ and site-coverage allowance. If the existing house already uses most of it, your room may be smaller than you hoped.
- Boundary distances: extensions must respect the setbacks from your plot boundaries as a rule of thumb, 3 m from a road boundary, and 3/4/5 m from other boundaries depending on the number of floors (Παράρτημα Β §11; current figures in Εντολή 4/2026 §5).
- The neighbours’ amenity: overlooking, light, and overshadowing are all assessed.
Documents and process, in brief
The same route as any planning application: a licensed architect or civil engineer prepares the drawings and submits form ΕΑ15 through ΙΠΠΟΔΑΜΟΣ (electronic only since 1 July 2024), with the title certificate, survey plan and the required consultations. In the Larnaca district, the authority is the ΕΟΑ Λάρνακας. After planning permission, a building permit follows for the works. (New to the two-permit structure? See planning permission vs building permit.)
The takeaway
Before you commit to an extension, get an architect to confirm two things: that the extra area fits within your plot’s ΣΔ and coverage, and that the setbacks work. Those two checks decide what’s actually buildable – and they’re far cheaper to run before you design than to discover at submission.
