Sources: 15. Developments: 2. Residents in four communities near Isla Blanca, Mexico, have reported administrative blockages regarding property procedures since March. Local leaders attribute these difficulties to the Secretariat of Agrarian, Territorial, and Urban Development (Sedatu), noting that issues emerged following the announcement of a new highway connecting Cancun and Isla Blanca. While residents do not oppose the highway, they expressed concerns regarding ecological fragility and the lack of direct benefits to their communities. In a related development in Isla Mujeres, authorities closed nine real estate developments in the Continental Zone. The closures, conducted by the Isla Mujeres City Hall and the Quintana Roo Secretariat for Sustainable Territorial and Urban Development (SEDETUS), were prompted by the sale of land without required permits and legal authorizations. Officials stated the intervention aims to prevent fraudulent real estate transactions and ensure compliance with federal, state, and municipal regulations. ## Timeline ### 2026-11-06: Isla Mujeres authorities shut down nine real estate developments Nine real estate developments in Isla Mujeres, Mexico, have been shut down by authorities for selling land without proper permits or legal authorizations. 13 sources. https://clstr.news/cluster/isla-mujeres-authorities-shut-down-nine-real-estate-developments ### 2026-10-29: Isla Blanca residents report property permit blockages Residents near Isla Blanca, Mexico, allege that Sedatu has blocked property transactions and permits following the announcement of a new Cancun-Isla Blanca highway project. 2 sources. https://clstr.news/cluster/isla-blanca-residents-report-property-permit-blockages --- Cite as: Isla Blanca and Isla Mujeres land permit disputes.
