3837-3839 21st St, San Francisco, CA 94114

The two-unit residential building at 3837-3839 21st Street, constructed in 1900 and currently owned by the Boultwood Family Rev Trust, has undergone several notable maintenance and repair activities over the years. The property has experienced some significant infrastructure work, including termite and dryrot damage repairs in 1999, reroofing in 1997, and a sewer repair with house trap installation completed in 2016.

More recent developments include a construction noise complaint in May 2023, though details on any associated work or impact were not specified in the records. The building has faced several environmental and infrastructure issues in recent years, with ongoing concerns about lifted sidewalk conditions from tree roots (opened in October 2022) and a previously resolved sidewalk defect in 2022 that required enforcement action and permit correction.

The property has had multiple parking-related incidents, including two cases of driveway blocking (most recently in October 2021 and October 2024), with parking enforcement unable to locate the violating vehicle in the latest instance. In early 2024, there were three reported incidents involving SFMTA Access/Mobility Services, though these were ultimately determined to be invalid complaints. The building's maintenance history suggests regular upkeep, with the most recent major infrastructure improvement being the 2016 plumbing work, while current records indicate no active building permits or major structural modifications in recent years.
