Spanish law forbids locking building entrance doors for safety

Closing a building's entrance door with a key is illegal in Spain due to safety regulations, particularly concerning emergency evacuations. Spanish law prohibits locking entrance doors with keys because they must open easily from the inside without a key, as per building codes for fire safety. The community of owners decides on common elements, but safety takes precedence. Alternatives like automatic closing systems or keyless access are permitted to keep the door closed, but failure to comply with regulations can result in fines and liability for damages.
