The favelas are spontaneous occupations that take place in a disorderly manner, without prior definition of plots and streets, in public or private areas owned by third parties, with inadequate infrastructure networks, where dwellings, mostly self-built and with a high degree of precariousness, are occupied by low-income families in situations of vulnerability.

• 1.747 favelas registered by the Secretariat
• 399.458 households in favelas estimated by the Secretariat

The upgraded areas are former favelas equipped with infrastructure such as water, sewerage, public lighting, drainage and garbage collection, made possible by actions of public authorities or not. However, they have not yet been legally regularized.

• 438 upgraded areas

Irregular allotments are those created on the initiative of a developer and/or commercialization agent without prior authorization from the competent public bodies, or those that, although authorized or in the process of being authorized, are implemented in contradiction with the legislation or the approved project. Irregular allotments are mainly occupied by low-income populations, have street widths, minimum plot sizes and sidewalk widths outside the urban standards established by municipal regulations, high building densities and poor urban infrastructure, with few green, free and common spaces.

• 1.996 irregular allotments
• 394.201 plots in irregular allotments
