Catalan Decreto-ley 4/2023 (Coliving regulation)
What it does: Imposes minimum room sizes (8 m² single, 12 m² double), maximum occupancy density, mandatory residential lease structure, minimum stay periods, and tenant rights specifically for shared housing including coliving. Targets 'cohabitation arrangements with common services'.
Trigger: Any operation marketed as coliving in Catalonia, regardless of branding.
Fix: Re-engineer the unit mix to meet the size minimums. Many existing coliving conversions in Barcelona violate the 8/12 m² rule and have had to either reconfigure or exit. Run room-by-room measurement audits before LOI.
