The ECUV certificate in Valencia: what it does and cannot do
The ECUV certificate in Valencia: what the private verification bodies do for licences and for extensions built without one, their hard limits, timings and costs.

What you will learn
- What an ECUV is and what its certificate replaces
- Why it cannot legalise an extension the plan does not allow
- How timings differ between towns, as estimates
An ECUV certificate in Valencia is a certificate of conformity issued by a private, accredited body, an entidad colaboradora de la administración (ECUV), which checks a building project against the planning rules before the town hall decides on it. It can save time on a licence. It is not a licence, it is never automatic, and it cannot make legal what the town's plan does not allow. That last point matters most when you buy a house with an extension that was built without a licence.
Who issues an ECUV certificate, and what it replaces
ECUVs are regulated by Decreto 62/2020 of the Consell. They must be accredited by ENAC, the national accreditation body, hold civil liability insurance and be entered in the Generalitat's register of these bodies. Using one is voluntary: the owner chooses it and pays its fee.
Their role is set out in the Valencian planning law, the TRLOTUP. An ECUV can check that a project and its documents are complete and comply with the rules, report on works in progress against the licence, and certify finished works for first occupation. For a licence, its certificate of conformity has the same validity and effect as the town hall's technical report, and it replaces that report without further checks by municipal technicians. The town hall still writes the legal report and still grants or refuses the licence. This wording comes from Ley 5/2026, in force since 11 August 2026, which also requires ECUVs to follow the technical criteria each town hall publishes on its website.
For smaller works that only need a responsible declaration (declaración responsable), you may start once the declaration is filed with the required documents, and the town hall checks afterwards. Since August 2026 it has one year to complete that check. Some works, such as structural reforms, demolitions and changes of use, need a declaration backed by a certificate from a certification body or a professional college.
Extensions without a licence: the hard limits
Many older villas on this coast have a closed porch, an extra bedroom or a pool house that was never licensed. Under the planning law, for 15 years from the day such works were finished, the town hall can require the owner to apply for the licence or bring the works into line, and order them removed if they cannot be legalised. On rustic land (suelo no urbanizable), on land planned for green zones, roads or public facilities, on public domain and on listed heritage, there is no time limit at all.
Fifteen years passing does not make the works legal. The law says plainly that while the breach remains, no works of reform, extension or consolidation may be carried out on what was built illegally; the town hall may only order works needed for safety, health and the appearance of the surroundings. For a buyer this means a house you may not be able to extend, improve or rebuild as you planned, and a question you will meet again when you sell.
Where the works do comply with the plan, legalising them means applying for a licence for what was built, with a project by an architect, and paying the town's fees and taxes. In principle an ECUV can verify the technical side of that file as it would for any licence; confirm with the town hall that it accepts this route for a legalisation. Where the works do not comply, because of the land's classification, the permitted floor area, the setbacks, the coastal law or a protected area, no certificate changes the answer.
Tourist lets have one more limit. An ECUV may issue the tourist compatibility report in place of the town hall only where the town's planning is zoned and contains rules on tourist homes, and that has to be checked town by town. Our guide to the tourist licence in Valencia covers that route.
Timings by town, as estimates
The law gives a town hall two months to decide a licence for major new building works or an equivalent structural reform. In practice files on this coast often take longer, and an ECUV only shortens the technical part. The figures below are our working estimates for 2026, not official averages, and they move with each department's workload.
Teulada-Moraira. The town hall announced the use of ECUVs on 1 September 2025 to shorten permit times. Even with a certificate, the legal report and the resolution remain the slow step. Plan for six to twelve months or more for a major works licence.
Calp. The town council approved the ECUV procedure at its plenary session of November 2025, saying its planning department was overloaded; applications go in with the project and the certificate of conformity. A standard major works file may take around two to four months, but treat that as a hope, not a promise.
Other towns. The regional rule applies in every Valencian town, whether or not the town hall has announced anything. Where the delay lies in the legal report or in a planning dispute, a certificate helps less. Ask the planning department how it handles ECUV files before you rely on one.
Costs, and when an ECUV is worth it
Each ECUV sets its own prices and must communicate them to the Generalitat every year, so ask two or three for a written quote for your project. The fee comes on top of the architect's fees and the town's fees and taxes. It pays off when the project is complete and clearly compliant. It is money lost when the real obstacle is the plan, the coast or the legal status of what already stands.
Before you buy a house with extensions, compare what is built with what the licences and the Catastro record show, and ask an independent lawyer or architect whether each part can be legalised at all. Price the house on that answer, not on hope. Our guide to building permits explains the wider process, and the properties to renovate on the market now are the next step.
