421-423 Parker Ave, San Francisco, CA 94118

The three-unit residential building at 421-423 Parker Avenue, located in San Francisco's Lone Mountain neighborhood, is a two-story flats and duplex structure built in 1963 and currently owned by Lin Ho Separate Property Tr. The property has undergone several significant maintenance updates over the years, most notably a complete reroofing project in 2018 costing $19,800, which was properly permitted and completed, following an earlier roofing permit from 1997 that had expired.

In 2010, the building's infrastructure was improved with the installation of a gas line from the meter to a fireplace for future use. The property has experienced various neighborhood-related incidents over the past decade, with the most recent being a september 2023 report of tipped-over litter receptacles, which remains unresolved as of the latest data.

Other incidents include a series of Recology service requests in 2021 for street cleaning, two instances of street and sidewalk cleaning in 2020, and a sidewalk defect investigation in 2013 which was resolved when no issues were found. While these incidents are primarily related to public space maintenance rather than building-specific issues, they provide context about the property's immediate surroundings. There's no record of any serious building code violations or safety concerns directly related to the structure itself in the available data.
