Each suco has a ''chefe''. Those in Dili have less influence over community land than those elsewhere, however their elected status gives them greater authority in other areas. Each also has a head office. Municipal and national government buildings are concentrated in the city centre, mainly in the sucos of Caicori, Colmera, and Gricenfor. Sucos, administrative posts, and municipalities are all tasked with setting up a Disaster Management Committee. These are responsible for planning, public awareness, and disaster response. The borders of sucos, and the aldeias within them, are often undefined. Reasons for this include the history of displacement, and taboo over formal demarcation.
