House (casa) renovation in València

A valid declaración responsable with all required documents enables the covered works to start on filing, subject to municipal checks. Filing is not a licence or confirmation that an unsuitable project is lawful.

The start and completion of declared works must each be notified to the Ajuntament within 15 days of the event, with the documents required by article 28.

A works declaration does not itself authorise scaffolding or temporary equipment to occupy public ground or airspace. UR.LC.135 requires the applicable public-domain occupation authorisation before that occupation begins.

LOE article 2 requires a project for existing-building works that alter architectural configuration, including specified substantial changes to exterior composition, volume or the overall structural system, and changes of characteristic use. It also covers interventions affecting protected elements of listed buildings; not every interior refit meets these tests.

València’s ICIO rate is 4% of the taxable execution material cost. The declared budget, applicable exclusions and any relief must be checked for the particular works.

The planning fee (tasa urbanística) starts at €140.90 for a base of up to €6,010.12 and rises on a sliding scale. It uses the same base as ICIO.

València’s ICIO ordinance reduces the tax due by 95% on the part of the works that installs solar thermal or photovoltaic systems, provided the equipment is homologated and an installation certificate and broken-down budget are supplied (art. 6.2.B). It does not apply where the installation is compulsory under specific regulations, and it is requested with the licence application or when the declaración responsable is filed (art. 7).

València’s IBI ordinance reduces the property tax by 50% for predominantly residential buildings with solar thermal or electric systems installed, from the year after installation, for a number of years that depends on the cadastral value and falls to none at the highest values. It must be requested, cannot exceed 20% of the installation’s final cost and does not apply where the installation is compulsory (art. 15).

Ordinary dwelling renovation or repair can qualify for 10% IVA when the recipient is a private individual using the dwelling privately, construction or rehabilitation finished at least 2 years before the works, and contractor-supplied materials cost no more than 40% of the taxable base. Qualifying communities of owners are also covered by the law.

The general IVA rate for ordinary repair or renovation is 21%; the private-home reduced-rate route does not cover rented or business-use dwellings. Construction and works meeting the tax definition of rehabilitation have a separate reduced-rate test, so the contract must be assessed before assigning a rate.

CTE DB-HE assigns climate zones by province and altitude: in the province of València, sites up to 50 metres above sea level are zone B3, and the same document gives the capital an altitude of 13 metres. The zone feeds DB-HE’s energy-saving requirements for interventions within the CTE’s scope.

For residential building work within the LOE’s project requirements, the law assigns the architectural project and works direction to an architect, and material execution direction to a technical architect. Specialist designers and other technicians act within their legal competence and the agreed project team.

RITE covers fixed heating, cooling, ventilation and domestic hot-water installations, including the reformed part of an existing installation. The scope and capacity determine the technical documentation and commissioning requirements; applicable certificates and operating information form part of handover.

For works within RD 105/2008’s project requirements, the project includes a waste management study and the contractor prepares the corresponding management plan; waste transfers need documentary evidence. Minor domestic repair works have a specific exception from those national producer and holder duties and follow local requirements.

València’s 2023 noise ordinance allows works in buildings that affect the public domain from 08:00 to 22:00, Monday to Saturday, and from 09:30 to 22:00 on Sundays and public holidays, with exceptions for urgent or authorised work (art. 31). Noisy domestic renovation is also banned at night: 22:00 to 08:00 from Sunday to Thursday, and 22:00 to 09:30 on Fridays, Saturdays and the eves of holidays (art. 30).

For building works covered by the LOE, the completed project with approved changes, reception record, identification of participants and use and maintenance instructions form the building book delivered to users. The documents required for a smaller renovation depend on its scope and installation work.
