46-48 Henry St, San Francisco, CA 94114

The two-unit residential building at 46-48 Henry Street in Duboce Triangle, owned by Mario M. Castillo, is a two-story flats and duplex structure built in 1907. The property has undergone several significant maintenance and improvement projects over the years, most notably the replacement of an 80% AFUE furnace in 2018 and two gas meter relocations in 2008.

A major cluster of building violations was recorded in July 2015, including issues with floor coverings, weatherproofing of the garage door, stairs guardrail repairs, and concerns about lead-based paint, though all these violations were abated by September 2015. That same year, there was a complaint regarding non-functioning stove and unsafe stairs, which was also resolved. A more recent concern was filed in January 2017 regarding asbestos-wrapped heating ducts, though this complaint was marked as not active.

The building's maintenance history shows attention to roof care, with a reroofing project completed in 2003 at a cost of $8,860. While there have been multiple 311 calls related to the property's immediate vicinity from 2019 onwards, these primarily concerned street parking and tree maintenance issues rather than building-specific problems. Recent external matters included several reports of vehicles blocking driveways or parking on sidewalks in 2021-2022, and tree-related complaints in 2019 regarding street trees. The property's documented history suggests that while there have been periodic maintenance issues requiring attention, these have generally been addressed within reasonable timeframes once brought to attention.
