The placement of padlocks on fire hydrants, as observed on Rua Princesa D. Amélia, is strictly prohibited by law. This practice, often used to hide keys for Local Accommodation, can seriously compromise emergency response.
Obstructing, concealing, or damaging street signs or mandatory local accommodation signage constitutes a serious offense, subject to fines. Even when attached to support posts rather than the signs themselves, these actions are illegal. Signage posts are considered urban furniture and municipal public property.
Local Accommodation owners cannot use public posts to affix private property without a permit from the Municipal Council, which is not granted for public key safes. Attaching unauthorized objects to public equipment is an offense punishable by fines. For legal self check-ins, electronic locks or key safes installed on private property or through local business partnerships are recommended.
