Yes, tiny homes are legal in Chile, but their compliance hinges on adherence to municipal zoning and construction norms. The Reglamento General de Urbanismo y Construcciones (RGUC) governs their legality, while municipal ordinances often impose additional restrictions. Recent 2026 updates to the Ley General de Urbanismo y Construcciones emphasize energy efficiency and seismic resilience, requiring tiny homes to meet structural standards akin to conventional dwellings.
Key Regulations for Tiny Homes in Chile
-
Zoning Compliance: Municipalities (e.g., Santiago, Valparaíso) classify tiny homes as accessory dwelling units (ADUs) or secondary residences. Approval requires alignment with Plan Regulador Comunal (PRC), which may restrict placement to rural or non-urban zones. Coastal areas often impose stricter limits under the Ley de Costas.
-
Construction Standards: Under RGUC Article 4.1.10, tiny homes must comply with Norma Chilena 433 (seismic design) and Norma Chilena 1079 (thermal insulation). Prefabricated models require certification from the Instituto Nacional de Normalización (INN).
-
Utilities & Permits: Connection to potable water, sewage, and electricity mandates permits from Superintendencia de Servicios Sanitarios (SISS) and local Servicio de Electricidad. Off-grid systems (e.g., composting toilets) require environmental impact assessments under Decreto Supremo 40/2012.
