Reurb (Law 13.465/2017) has two modalities with very different rules on fees, deadlines, and obligations. This tool indicates which one applies to your case.
Four short questions. The answers combine the social criterion (income and declaration of interest) with the risk criterion. No data is sent to servers: everything is processed in the browser.
Informational guidance. The definitive classification depends on the technical analysis of the municipality and, for Reurb-S, on an act of the municipal Executive declaring the social interest, under article 13 of Law 13.465/2017.
The two modalities share the procedure, but they change who pays, who initiates, and which titling instrument will be prioritized. The main points:
| Aspect | Reurb-S | Reurb-E |
|---|---|---|
| Target population | Settlements with a low-income population so declared | Other settlements |
| Legal basis | Article 13, I of Law 13.465 | Article 13, II of Law 13.465 |
| Fees and registry charges | Full exemption on registration | Costs borne by beneficiaries or developer |
| Initiative | Usually the municipality | Municipality, beneficiaries, or other legitimate parties |
| Instruments | Land legitimization preferred | Land legitimization, sale, donation |
| Risk areas | Technical study + mitigation or relocation | Same rule |
| Implementing decree | Decree 9.310/2018 | Decree 9.310/2018 |
Articles 39 to 42 of Law 13.465, combined with article 30, III, require every Reurb installed in an area of geotechnical, environmental, or flood risk to be preceded by a technical study assessing the feasibility of regularization. The study is a mandatory part of the land regularization project and does not replace environmental licensing where applicable.
If the risk is mitigable, Reurb proceeds together with the containment works and measures provided. If the risk is non-mitigable, the law provides for the relocation of the occupants to another area, with the public authority taking responsibility for the new destination. There is no shortcut: the risk stage precedes titling and, in many cases, redefines the design of the regularized settlement.
Regardless of the modality, Reurb goes through the same six stages. What changes is who initiates, who pays, and which instrument will be used for titling.
This simulator is a guidance tool. It combines the most common criteria to distinguish Reurb-S from Reurb-E, but the final decision always passes through the technical analysis of the municipality, the act of the Executive when applicable, and the registration at the competent real estate registry. Settlements with hybrid situations, de facto condominiums, areas with multiple owners, occupations on federal land, or in environmental protection areas require case-by-case review.
For complex cases, large areas, settlements in risk areas, or processes with multiple possible modalities, specialized legal and technical assistance is strongly recommended. Arsenic can act in the diagnosis of the settlement, in the regularization project, and in dialogue with the municipality and the registry, integrating urbanism, law, and topography in a single team.
