Yes, keeping backyard chickens is legal in Brazil under specific municipal and state regulations.
The legal framework permits backyard poultry farming, but compliance with local sanitary, zoning, and animal welfare laws is mandatory. Municipal ordinances often dictate flock size, coop placement, and registration requirements, while federal norms from the Ministry of Agriculture (MAPA) govern disease control. Recent 2026 updates to the Plano Nacional de Sanidade Avícola (PNSA) reinforce biosecurity standards, requiring owners to report flock health irregularities to local veterinary authorities.
Key Regulations for Keeping Backyard Chickens in Brazil
-
Municipal Zoning Laws: Most cities restrict coop locations to non-residential areas or require minimum distances from neighboring properties. São Paulo’s Lei Municipal 17.262/2020 mandates a 10-meter buffer from residential zones, while Rio de Janeiro’s Decreto 49.210/2021 limits flock sizes to 20 birds without permits.
-
Sanitary and Health Compliance: Federal Decree 10.460/2020 enforces MAPA’s Regulamento de Defesa Sanitária Animal, obligating owners to register flocks in the Sistema de Defesa Agropecuária (SDA) and vaccinate against Newcastle disease. Unregistered flocks face culling under PNSA emergency protocols.
-
Animal Welfare and Waste Management: State-level resolutions, such as Paraná’s Resolução SEMA 001/2023, require coops to meet ventilation and space standards (minimum 0.5 m² per bird) and prohibit open-air waste disposal. Non-compliance may trigger fines under environmental legislation (Law 9.605/1998).
