3891-3893 Clay St, San Francisco, CA 94118

The property at 3891-3893 Clay Street is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by the Victoria C Smith Trust and located in San Francisco's Presidio Heights neighborhood. The building has undergone significant renovations and improvements over the past decade, with substantial work completed in 2014-2015 including multiple unit updates totaling over $150,000 in improvements to kitchens, bathrooms, and general renovations. A fire safety upgrade was completed in 2010 with the installation of a three-head sprinkler system protecting an exterior stairwell.

Recent plumbing work in 2019 included installation of a backwater valve in the garage and extension of the house trap vent through the sidewalk. Currently, there is an active building complaint filed in April 2019 regarding a defective or missing fresh air inlet and house trap that remains unresolved as of October 2023. The property has experienced several maintenance issues in the surrounding area in recent months, including a collapsed sidewalk (reported October 2024) and various tree-related concerns, though these are external to the building itself.

Historical planning records show attention to compliance matters, with successful approval for replacing non-complying rear stairs and enclosing a third-floor roof deck. Regular street space permits have been obtained over the years, indicating ongoing engagement with municipal requirements for public space use. The building's systems have generally been well-maintained, with multiple completed permits for various upgrades, though the 2019 air inlet issue represents the only currently active violation on record.
