418-420 35th Ave, San Francisco, CA 94121

The three-story multi-family residential building at 418-420 35th Avenue in the Outer Richmond, owned by the Lin Family Revocable Living Trust, has undergone significant recent renovations and improvements since 2022. Most notably, there has been substantial work related to fire safety systems, with multiple permits issued in 2024 for sprinkler system installations and a 400-amp service upgrade, including electrical vehicle charging infrastructure.

The property has also seen the conversion of existing workshop and storage spaces into an ADU unit at the ground floor, with associated plumbing and electrical work completed or in progress throughout 2024, representing a major investment of over $145,000 in improvements. Historically, the building faced several concerns between 2002 and 2008, including serious fire hazard violations in 2002 related to blocked exits and combustible materials, which were abated in 2004.

There were multiple instances of unauthorized unit conversions and construction work beyond permitted scope between 2006 and 2008, with complaints about illegal units in the garage and basement, though these issues appear to have been resolved. The property has had several renovation projects, including a kitchen remodel in 2019 and various compliance issues related to building maintenance and plumbing systems, particularly bathroom repairs which were documented through complaints and permits. Most recently, there have been concerns raised in mid-2024 regarding unpermitted work and inspection discrepancies, though these complaints were marked as "Not Active." The building's permit history shows a pattern of proactive upgrades, particularly focusing on fire safety and electrical infrastructure in recent years, though there have been notable compliance challenges in its past that required intervention.
