4228 22nd St, San Francisco, CA 94114

The two-unit, two-story residential building at 4228 22nd Street in the Eureka Valley/Dolores Heights neighborhood was constructed in 1902 and is currently owned by the William M Robinson Revocable Trust. The property has undergone several significant maintenance and improvement projects over its history, with the most recent major works occurring in 2014, including both street space/sidewalk improvements and substantial plumbing upgrades involving the replacement of clay pipes with cast iron pipes.

The building's renovation history reveals ongoing maintenance and modifications from 1985 through the early 1990s, including a notable project in 1985 to remodel the second floor and convert the attic to a third floor, though many of these permits ultimately expired, suggesting either completion under different permits or possibly some non-compliance issues. More recent concerns at the property have centered around infrastructure and maintenance issues in the surrounding area, particularly involving trees and pavement.

There are currently open cases from 2021 and 2022 regarding a collapsed sidewalk and tree root damage to the sidewalk, respectively. Earlier issues included a pavement defect reported in 2015 and three tree-related incidents between 2009 and 2019, including a fallen tree and an overgrown tree near communication lines, though these were generally addressed through standard maintenance procedures. While the building itself appears to be structurally sound based on available records, the surrounding infrastructure has required ongoing attention from city services, typically through the Department of Public Works.
