4579-4581 18th St, San Francisco, CA 94114

The two-unit residential building at 4579-4581 18th Street, located in the Eureka Valley/Dolores Heights neighborhood, is a two-story flats and duplex structure built in 1900, currently owned by Stephen Rogers and Sara Sadoughi. The property has undergone several maintenance and improvement projects over the past decade, including window replacements in 2014, bathroom and kitchen remodeling in 2011, and infrastructure upgrades such as a new house trap installation (2012), gas houseline extensions for both units (2011), and furnace replacements (2011).

The building experienced significant health and safety issues in mid-2010, with multiple violations documented between July and November of that year, including problems with water damage, mold and mildew, interior surface damage, plumbing issues, and inadequate heating. A particularly concerning complaint from July 2010 noted problems with a non-compliant furnace and heating system affecting both units, along with electrical issues including a faulty lighting fixture. All these violations were officially abated by September 30, 2010.

More recently, in January 2015, there was a reported issue with the sidewalk's condition near the property, specifically concerning a collapsed section and vent system connection, though this was subsequently resolved. The building's permit and violation history suggests that while there were serious maintenance and safety issues in 2010, the property has since undergone various improvements, with no active violations or complaints on record in recent years. The most significant recent improvements include window replacements and the extension of gas lines for both units, indicating ongoing maintenance of the building’s basic systems and infrastructure.
