18-20 Barcelona Ave, San Francisco, CA 94115

The two-unit residential building at 18-20 Barcelona Ave, located in the Anza Vista neighborhood, is a two-story flats and duplex structure built in 1948, currently owned by the Eleanor Lee Ng Survivors Trust. The property has undergone several significant improvements over the past decade, with the most recent maintenance work involving gas houseline extensions in June 2022, though one of these permits has since expired.

In 2017, substantial repairs were made to the front entrance stairs, addressing dry rot issues and associated exterior wall stucco repairs, at a cost of $15,000. The building has seen interior upgrades including a bathroom remodel in 2012 that encompassed tile work, fixtures, and ventilation improvements, accompanied by corresponding plumbing and electrical permits.

Additional improvements to the property's exterior were completed in 2011, when eleven energy-efficient windows were installed, meeting modern U-factor requirements without altering the building's structural elements. While the maintenance record shows regular upkeep and modernization efforts, particularly focusing on safety and energy efficiency, the expired gas line permit from 2022 warrants verification of the completed work status.
