In Brazil, unauthorized construction (construção clandestina) is a significant urban issue, particularly in favelas and informal settlements. The term is frequently used in discussions about urban development, housing rights, and municipal enforcement. In the USA and NYC, this is typically referred to in legal contexts and real estate regulations, often resulting in fines, stop-work orders, or demolition.
