Extensions and extra space (ampliaciones) in València

Before buying or designing, the Ajuntament offers an informe urbanístico and planning or heritage viability consultations. Article 13 sets response periods of 1 month for the report and 3 months for the consultations; these are statutory periods, not promised project dates.

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.

Declared works must start within 6 months of filing and finish within 24 months of starting. The ordinance does not allow extensions except for stoppages caused by force majeure.

For building work, a professional college visa is compulsory only on the execution project and the final-works certificate of works that need a project under LOE article 2.2, on those documents in legalisation procedures, and on demolition projects that do not use explosives (art. 2).

The tasa and ICIO are paid before the declaración responsable is filed.

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.

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.

Article 17.4 includes a three-fifths vote of all owners and participation quotas for specified structural or common-element alterations, including terrace enclosure, with affected owners’ consent where applicable. Compulsory works and other specific statutory routes must be considered separately.

The seismic standard NCSE-02 lists València with a basic seismic acceleration of 0.06 g and a contribution coefficient K of 1.0 (Annex 1). The standard does not apply to buildings of moderate importance and has further exceptions depending on the building and its structure, so the structural designer establishes whether and how it applies.

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.

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.

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.
