Renovating in South Tenerife: The Owner's Guide to Permits, Timelines and Who Does What
You have found it. The apartment with the terrace that catches the evening sun, or the villa that needs — well, everything. And somewhere between the excitement and the first moodboard, a quieter question shows up: am I actually allowed to do all this?
Short answer: almost certainly, yes. Longer answer: this guide. Pour yourself a coffee. By the end you will know how renovation permits really work in the south of Tenerife, who does what, and where the time actually goes.
Two doors into your renovation
Building works in the Canary Islands are governed by one main law: Ley 4/2017 del Suelo de Canarias. It sounds heavier than it is. For a home renovation, the law essentially offers two doors.
Door one: the comunicación previa
This is the light route, and the one most interior renovations take. Works of conservation, reform or rehabilitation that do not increase the volume or buildable area of the property — and do not touch a protected, catalogued building — fall under article 332 of the law. You do not wait for an approval: you notify your town hall at least fifteen days before the works begin, and if your file is in order, you can start.
Door two: the licencia urbanística
The formal route, reserved for the bigger moves listed in article 330: new construction, extensions that add volume, works on catalogued buildings and certain façade changes — including glazing in a terrace when it forms part of a whole-façade project. Here the town hall reviews and approves before anything starts, and that review takes the time it takes.
You will also hear people talk about obra menor and obra mayor. Those are the older, everyday labels — many town halls still print them on their forms — but the split that legally decides your route is the one above.
So which door is yours?
What you are planning | The usual route |
New bathroom, new kitchen, new floors — no structural changes | Comunicación previa |
New wiring or plumbing within the same layout | Comunicación previa |
Opening or removing load-bearing walls | Ask your architect — the project decides the route |
Adding volume, extending, closing a terrace into the façade | Licencia urbanística |
Any work on a catalogued or protected building | Licencia urbanística |
One honest caveat: every municipality applies the law through its own ordinances and forms, and Arona's counter is not Adeje's. Treat the table as a compass, not a map — your architect confirms the route for your exact address.
Who does what
You, the owner. Decisions, signatures and the permit itself — permits are always issued in the name of the property owner, and stay the owner's responsibility.
The architect or aparejador. Draws up the technical project where one is needed, signs the works direction and contracts directly with you.
The town hall. Receives your file, applies its ordinances and collects the municipal taxes and fees that come with works.
Arbeprojects. Design, planning and the coordination of trusted local contractors — plus help preparing your permit file on a best-efforts basis, so you never walk into the town hall unprepared.
Living in a community of owners?
Then there is one more conversation before the town hall: your community. Anything that touches shared elements — the façade, the structure, communal plumbing — usually needs the community's consent under Spain's horizontal property rules, and your building's own statutes may add rules about awnings, terraces and working hours. A short chat with the administrador de fincas early on saves weeks later.
Where the time really goes
Design and measurements — the fun part, and the one that decides everything else.
The technical project, where one is needed, drawn up and stamped by your architect.
The town hall step: fifteen days of notice for a comunicación previa, a full review for a licencia.
The works themselves, coordinated so every trade arrives in the right order.
The finishing weeks: paint, joinery, curtains, styling — the part you will actually remember.
We will not promise you municipal timelines — nobody honestly can. What we can promise is that your file never sits waiting because of us.
A renovation is not paperwork with some building attached. It is a home taking shape — the paperwork is just the metronome.
Ready when you are
