3963 Mission St, San Francisco, CA 94112

The 4-unit, 2-story multi-family residential building at 3963 Mission Street in Bernal Heights, owned by Chin Fmly Trust and constructed in 1952, has undergone several significant modifications and faced multiple regulatory challenges over the years. Most notably, in 2003, following housing inspector violations, the property underwent substantial corrective work including the removal of an illegal kitchen and legalization of various ground floor spaces (exercise room, full bath, social room) at a cost of $13,000, along with extensive electrical work including installation of 15 lights, 15 switches, and 20 receptacles to bring the building into compliance. The property has a documented history of unauthorized modifications and safety violations, particularly in 2003 when multiple serious issues were identified including unapproved wiring and plumbing, lack of required smoke detectors, improper exiting configurations, and questionable fire safety features.

These violations were largely addressed through the 2003-2004 corrective work, which included both building and electrical permits that were subsequently completed. The building has undergone several routine safety inspections over the years (2000, 2003, 2008, and 2015), with the most recent in 2015 showing no active violations. While there was one recorded fire incident classified as a false alarm with no civilian injuries, this appears to be the only fire-related event on record.

Recent activity at the property has primarily consisted of external maintenance issues documented through 311 calls, including multiple reports of garbage and debris (2024), pavement defects (2024), and parking enforcement requests. The most recent building-related incident was a parking enforcement issue from December 2024. It's worth noting that all historical housing violations have been marked as "Not Active," indicating they have been resolved, though there are some ongoing concerns related to parking and street cleanliness in the immediate vicinity of the building. All maintenance and compliance actions taken appear to have been in response to housing authority inspections and violations, with no recent history of unauthorized modifications or safety concerns since the 2015 inspection.
