1438 18th Ave, San Francisco, CA 94122

The two-unit multi-family residential building at 1438 18th Avenue in San Francisco's Inner Sunset district is a two-story flats and duplex structure owned by Sophie L Wong 2020 Grantor, dating back to 1925. The property has undergone several significant maintenance and improvement projects over the past three decades, including two complete roof replacements - one in 1993 and another more recent project in 2010 costing $11,950.

In 2002, substantial exterior improvements were made with the replacement of wood elements with vinyl throughout the front of the building, involving the installation of 11 dual-glazed low-emissivity glass windows, for a project cost of $5,300. The building's service call history reveals relatively minor and routine issues over the past decade, with no major emergencies or code violations reported.

The most recent incidents include a parking enforcement call in July 2023 regarding a blocked driveway (though the responding officer was unable to locate the vehicle), and a street cleaning request for loose garbage in August 2020 that was resolved by the Department of Public Works. An unrelated water utility callback was logged in November 2012, which was directed to Grid One and subsequently resolved. While the property has maintained regular upkeep with periodic major improvements, the service call history suggests typical neighborhood maintenance issues rather than any building-specific concerns.
