Full Renovation Contract Spain (Contrato de Reforma Integral)

A Full Renovation Contract Spain (Contrato de Reforma Integral) under Código Civil Article 1588 is a formal legal agreement between a property owner (propietario or comitente) and a renovation contractor (contratista de reformas) by which the contractor undertakes to carry out thorough renovation works on a residential or commercial property — typically involving the complete or near-complete refurbishment of a dwelling, office, commercial premises, or building — for an agreed fixed price (precio alzado) or measured works price, within a defined timeline, under the general framework of the contrato de obra (works contract) in Spanish civil law. The Código Civil Articles 1588–1600 govern construction and renovation contracts between private parties in Spain, establishing the contractor's obligations of professional performance, the owner's obligation to pay the agreed price, and the parties' rights in cases of delay, defects, and variation.

For renovation works that affect the structural integrity, habitability, or energy performance of a building — such as load-bearing wall removal, foundation reinforcement, roof replacement, or major façade works — the Ley 38/1999, de 5 de noviembre, de Ordenación de la Edificación (LOE) applies alongside the Código Civil, triggering the mandatory liability periods of LOE Article 17 (one year for finishing defects, three years for habitability defects, ten years for structural defects) and, for works meeting certain thresholds, the mandatory decennial structural defect insurance under LOE Article 19. Major renovation works in urban areas also require a building permit (licencia de obra mayor) from the Ayuntamiento under the Ley del Suelo and applicable Autonomous Community urban planning legislation.

The Código Técnico de la Edificación (CTE — Real Decreto 314/2006, updated by Real Decreto 732/2019) applies to all significant renovation works, establishing minimum technical standards for structural safety (DB-SE), fire safety (DB-SI), accessibility (DB-SUA), health (DB-HS), acoustic insulation (DB-HR), and energy efficiency (DB-HE). Compliance with CTE DB-HE (energy efficiency) is particularly relevant for renovations funded under the Plan de Recuperación, Transformación y Resiliencia (PRTR) through the MOVES III programme or Programa REHABILITA, which offer subsidies for energy-efficient renovations under Real Decreto 853/2021.

VAT applicable to renovation works in Spain depends on the nature of the property and works. Under Ley 37/1992 del IVA Article 91.Uno.2, renovation and repair works on residential buildings (viviendas) are taxed at the reduced rate of 10% IVA — provided the property has been used as a dwelling for at least two years, the works are contracted directly by the owner or tenant, and materials incorporated do not exceed 40% of the total contract price. Works that do not meet these conditions are taxed at the general rate of 21%. For commercial premises and office renovations, the general 21% IVA rate always applies. The Agencia Tributaria's criteria for applying the reduced rate are published in binding consultations (consultas vinculantes) available through the AEAT portal.

The Ley de Propiedad Horizontal (LPH — Ley 49/1960, as amended by Ley 8/1999 and Ley 10/2022) governs renovation works in communal residential buildings (comunidades de propietarios). Works affecting common elements (elementos comunes) — staircases, façades, roofs, foundations, shared installations — require prior approval by the Junta de Propietarios (owners' meeting) under LPH Article 17. Individual owners wishing to renovate their private units (pisos o locales privativos) must obtain prior written authorisation from the Presidente de la Comunidad under LPH Article 7 when works could affect the building's safety, habitability, or aesthetic appearance, and must comply with the rules of the Comunidad de Propietarios documented in the Estatutos comunitarios filed in the Registro de la Propiedad.

Occupational health and safety requirements under Ley 31/1995 de Prevención de Riesgos Laborales and Real Decreto 1627/1997 apply to renovation works on sites where multiple contractors or workers are engaged — the property owner or commissioning party assumes duties analogous to the LOE promotor regarding safety coordinator appointment and Aviso Previo notification to the Autoridad Laboral for qualifying projects.

A Full Renovation Contract Spain is required whenever a property owner engages a renovation contractor for thorough refurbishment works on a residential dwelling, commercial premises, or office space — establishing the scope, price, timeline, and warranty obligations that govern the works.

The contract is needed for integral renovation of a residential property (reforma integral de vivienda) — complete refurbishment including kitchen, bathrooms, flooring, plastering, electrical rewiring, plumbing, HVAC, and carpentry — where the total cost and complexity of works justifies a formal written contract to protect both owner and contractor.

A Contrato de Reforma Integral is required when applying for a licencia de obra mayor from the Ayuntamiento — the building permit application typically requires a works contract or at least a budget (presupuesto) as part of the application documentation, alongside the project prepared by a licensed arquitecto or arquitecto técnico.

The contract is needed for commercial premises renovation (reforma de local comercial) — fitting out an office, restaurant, retail shop, or hotel — where the owner or tenant commissions thorough works before opening for business, and where compliance with sector-specific technical regulations (fire safety under DB-SI, accessibility under DB-SUA) must be documented.

A Full Renovation Contract is required as supporting documentation for subsidy applications under Plan de Recuperación, Transformación y Resiliencia (PRTR) programmes — the MOVES III and Programa REHABILITA offer grants of up to 80% of eligible works costs for energy-efficient renovations under Real Decreto 853/2021, and the subsidy application requires a detailed signed contract with the works contractor.

The contract is also needed when the renovation is carried out in a property subject to a Ley de Propiedad Horizontal regime — the written contract serves as documentation for the Comunidad de Propietarios that the owner has engaged a qualified contractor and obtained the required community authorisation under LPH Article 7 for works affecting common elements.

Parties in Spain should prepare a Full Renovation Contract Spain (Contrato de Reforma Integral) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under the Ley de Sociedades de Capital (LSC) RDL 1/2010, the Registro Mercantil maintains the register of Spanish companies. The Código de Comercio 1885 governs commercial obligations. The Agencia Estatal de Administración Tributaria (AEAT) administers Impuesto sobre Sociedades (IS) under Ley 27/2014. The Comisión Nacional de los Mercados y la Competencia (CNMC) enforces competition law. The Código Civil governs general contractual obligations under Article 1255. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A valid Full Renovation Contract Spain under Código Civil Article 1588 and LOE 38/1999 must contain the following essential elements to define the parties' obligations and to protect both owner and contractor throughout the renovation process.

Identification of Parties: Full legal name, DNI/NIE/NIF, and address of the property owner (propietario or comitente) and the renovation contractor (contratista de reformas). Where the contractor is a company, the NIF/CIF, Registro Mercantil details, and the name of the legal representative. The contractor's professional qualification — whether works require a licensed arquitecto técnico (aparejador), ingeniero de edificación, or can be executed by a registered construction company without specific professional direction — should be stated.

Property and Scope of Works: Full address and cadastral reference (referencia catastral) of the property to be renovated, its current use (residential / commercial), and a detailed description of the complete scope of works (alcance de los trabajos) — listing every trade included: demolition (demolición), structural works (obra gruesa), plumbing (fontanería), electrical works (instalación eléctrica), HVAC (climatización), tiling (alicatado y solado), plastering (guarnecidos y enlucidos), painting (pintura), carpentry (carpintería), and finishes. The technical project or works memory (memoria técnica) and floor plans form part of the contract by reference.

Building Permits and Regulatory Compliance: Identification of any required Ayuntamiento licencia de obra mayor or declaración responsable, the party responsible for obtaining it (typically the owner), and confirmation of compliance with Código Técnico de la Edificación (CTE — RD 314/2006) requirements applicable to the renovation scope. For works in comunidades de propietarios, reference to the Junta de Propietarios authorisation under LPH Article 7 or 17.

Contract Price and Payment Schedule: The total agreed price (precio de contrata) excluding VAT, the applicable VAT rate (10% for qualifying residential renovations under Ley 37/1992 Article 91.Uno.2; 21% otherwise), and the payment schedule (calendario de pagos) linked to construction milestones — typically: deposit (señal) upon contract execution (10–20%), progress payments at defined milestones (structure complete, fit-out complete), and final payment upon handover after defects inspection (retención de garantía of 5–10% released after a defined period). The Ley 3/2004 de morosidad mandates maximum 30-day payment terms in commercial contracts.

Timeline and Penalty Clauses: The agreed commencement date (fecha de inicio), works duration (plazo de ejecución), and completion date (fecha de terminación). A daily or weekly penalty clause (cláusula penal por mora) for delay under Código Civil Article 1152 — expressed as a percentage of the contract price per day or week of delay beyond the agreed completion date, with a maximum cap. The contractor's right to extension (prórroga) for delays caused by the owner's changes, adverse weather, permit delays, or force majeure (fuerza mayor under Código Civil Article 1105).

Variations and Additional Works: The procedure for owner-requested changes to the agreed scope — written variation order (orden de variación) signed by both parties, specifying the additional cost and time impact before works commence. Código Civil Article 1593 permits the contractor to claim additional payment for owner-requested extras even without prior written authorisation where the owner has accepted the works, but written documentation is essential to avoid disputes.

Warranty and Defects Period: The contractor's warranty obligations post-completion — at minimum: one year for finishing defects under LOE Article 17 (if LOE applies); three years for habitability defects; ten years for structural defects. For renovations outside LOE scope, a minimum twelve-month post-completion defects period under general contract law is standard practice. A retention (retención) of 5% of the contract price held for twelve months post-completion as security against defects.

Health and Safety: Compliance with Ley 31/1995 de Prevención de Riesgos Laborales and, where multiple contractors work simultaneously, Real Decreto 1627/1997 — including Aviso Previo notification to the Autoridad Laboral for qualifying projects and Plan de Seguridad y Salud preparation.
