420-422 Frederick St, San Francisco, CA 94117

The three-unit residential building at 420-422 Frederick Street, owned by Valerie D Pollard, was constructed in 1907 and stands three stories tall in the Parnassus/Ashbury Heights neighborhood. The property's most significant structural maintenance issues occurred in 2003 when violations were filed regarding deteriorated stairs, which prompted both a building permit issuance and multiple Housing Inspection Services complaints that were finally abated in March 2005.

An earlier reroofing project was undertaken in 2006 at a cost of $22,510, though this permit has since expired. A street space permit was issued in 2008 for a nominal cost of $1. Recent history of the property shows several exterior maintenance issues in the surrounding area, with the most recent incident being a graffiti case reported in November 2024.

Between 2017 and 2024, there have been various municipal service calls primarily related to street cleaning and graffiti removal, including instances of hazardous materials (glass) in early 2024 and multiple cases of illegal postings, loose garbage, and sidewalk blockages. While these external issues do not directly affect the building's condition, they provide context about the property's immediate surroundings. The building's documented permit and violation history suggests that significant structural issues were addressed through appropriate channels, with no recent building violations recorded against the property.
