Pittsburg is revitalizing Delta waterfront city with the new eBART station and marina district development, with housing stock that includes 1940s-50s post-war cottages in Old Town and Los Medanos, 1970s-80s ranch and Spanish Revival in Highland Meadows, 1990s-2000s stucco production homes in Marina Highlands, and 2010s townhomes near eBART. These homes face specific challenges: aging 1970s-80s roofing stock with deferred maintenance common, T1-11 and hardboard siding swelling on older homes, and salt-carrying Delta winds corroding metal flashings near the waterfront.
