Spain fit-out standards: RD 486, CTE, RITE, licencia. Secure your Iberian office project in ~12 weeks with Kytom, a complete guide.
"What standards apply over there"
A rejected licencia de apertura blocks taking possession for 8 to 16 weeks, with an average prime Madrid rent of 39 EUR/sqm/month (source CBRE). Over 850 sqm, the monthly carrying surcharge exceeds 33,000 EUR, not counting contractual delay penalties and the double occupancy during the transition between sites.
RD 486/1997 requires 2 sqm of free space per workstation, 10 cubic metres of air and a minimum 3 m ceiling height. Non-compliance exposes you to Inspeccion de Trabajo penalties of up to 40,985 EUR (LISOS, serious infringement), and weakens labour relations with the Spanish employee representatives, who pay close attention to material conditions.
The CTE-DB-SI (fire safety) and the RITE (thermal installations) determine the issuance of the Certificado Final de Obra. A compliance gap blocks the comprehensive insurance and the Certificado de Eficiencia Energetica, now mandatory for letting since decree 390/2021. The landlord may then refuse the acceptance of the works.
Kytom operates in Spain through an integrated local agency, with architects registered with the Colegio Oficial de Arquitectos and health and safety coordinators compliant with Ley 31/1995. We systematically cross-check the client brief (often calibrated to French regulations) against the 5 structuring Spanish frameworks: RD 486/1997, CTE, RITE, RD 314/2006 and ordenanzas municipales. Our method produces a single technical file, enforceable with the town hall, the landlord and the insurer. On 850 sqm on average, we deliver in 12 weeks on average, licencia included. Real estate departments have a single French-speaking point of contact, and executives retain the budget clarity of a French project, without discovering a regulatory gap during the construction phase.
Audit of the target premises on the 12 critical points of RD 486 (floor areas, heights, lighting at 500 lux, sanitary facilities, emergency exits). Deliverable: bilingual compliance matrix, gaps quantified in euros and weeks, validated by the colegiado architect before signing the lease.
Early filing of the declaracion responsable or the licencia de obra depending on the autonomous community (timelines vary from 3 to 14 weeks between Madrid, Barcelona and Valencia). Deliverable: detailed administrative schedule, integrated into the works planning, with identified town hall milestones.
Technical plans compliant with CTE-DB-SI (compartmentalisation, smoke extraction), CTE-DB-HR (acoustics, minimum 45 dB between offices), RITE (air renewal at 12.5 l/s/person IDA 2). Deliverable: enforceable execution file, signed by the architect and the Spanish safety coordinator.
Handover with Certificado Final de Obra, Certificado de Eficiencia Energetica, and obtaining the licencia de primera ocupacion or actividad. Deliverable: complete digital logbook (plans, certificates, ten-year guarantees), transferred to the real estate department for internal audit and group reporting.
"We thought we could transpose our Parisian standards to Madrid. The Kytom audit revealed 7 CTE gaps in 48 hours, and we readjusted the lease before signing. Estimated saving: 4 months."
RD 486/1997 requires 2 sqm of free space per worker, 10 cubic metres of unoccupied volume, and 2.5 m ceiling height (3 m in new construction). These minimums are lower than tertiary practices, where the target is rather 8 to 12 sqm per workstation for performance.
Since 2012, many municipalities accept a declaracion responsable for unclassified tertiary activities, with subsequent inspection. Madrid and Barcelona apply it widely, but 30% of municipalities still require a prior licencia. Checking the local ordenanza before any filing remains essential.
The Codigo Tecnico de la Edificacion is the functional equivalent, structured into 6 documents (DB-SI fire safety, DB-SUA accessibility, DB-HR acoustics, DB-HE energy, DB-SE structure, DB-HS sanitation). It applies to any building, new or renovated, and determines the issuance of the Certificado Final de Obra.
The Ley sobre Infracciones y Sanciones en el Orden Social (LISOS) provides for up to 40,985 EUR for a serious infringement and 819,780 EUR for a very serious infringement. The Inspeccion de Trabajo y Seguridad Social inspects regularly, and the landlord may terminate the lease for non-compliant use.
The CTE-DB-SUA and RD 173/2010 set requirements close to the French framework: 1.20 m circulation routes, adapted sanitary facilities, signage. Each autonomous community adds its own decrees, sometimes stricter (Catalonia, Basque Country). A local audit is necessary for facilities open to the public.
Yes for works subject to a licencia de obra mayor: only an arquitecto registered with the Colegio Oficial can approve the project and supervise it. For a declaracion responsable on minor works, a competent technician is sufficient. Kytom includes a colegiado architect in every Iberian assignment.
