This is a starting list, not legal advice. What a building needs, and how often, depends on its use, size, risk category and equipment, and rules change. Check with your qualified people and current official sources.
What catches people out.
- Spanish decrees are often replaced: RD 2060/2008 became RD 809/2021, RD 2267/2004 became RD 164/2025, RD 88/2013 became RD 355/2024 and RD 865/2003 became RD 487/2022.
- Maintenance (by the maintenance company) and the periodic inspection (by an accredited body, OCA) are different deadlines.
- The autonomous communities add their own rules, so check your region.
