San Isidro Council Passes Urban Code Overhaul After Protests

Opponents plan legal challenges over a process they say excluded residents and skipped key impact studies.

Overview

  • The municipal council passed the overhaul May 6 with 14 votes in favor, 10 against and 4 abstentions in a session that ended with scuffles at the building entrance.
  • The new rules cover Villa Adelina, Boulogne and the coastal strip and allow smaller 35 m² studios in some zones, new multifamily housing types and commercial buildings up to 6.5 meters, while protecting the natural bluff, the coastline from new housing and pre‑1946 buildings.
  • Mayor Ramón Lanús and his bloc say the update will expand access to housing and guide long-term growth, with Lanús celebrating the vote on social media.
  • Opposition councilors and neighborhood groups argue the council skipped a full public hearing and prior environmental studies, warning of flood risk, heavier traffic and strains on basic services.
  • Residents and neighborhood assemblies say they will keep mobilizing and file complaints to reverse or modify the measure, and coverage also notes past complaints and probes tied to Lanús’s tenure at the national asset agency as context for the distrust.
