3909 Irving St, San Francisco, CA 94122

The two-story multi-family residential building at 3909 Irving Street in the Outer Sunset was constructed in 1963 and currently consists of four units. The property has undergone significant improvements and compliance upgrades in recent years, most notably the addition of an ADU (Accessory Dwelling Unit) on the first floor in 2019, which added two bedrooms, a living room, kitchen, and bathrooms at a cost of $80,000. Between 2020-2024, the building received substantial safety upgrades including a new fire alarm and sprinkler monitoring system ($13,934), a ground floor fire speaker system ($18,000), and a major electrical service upgrade to 400A completed in 2021.

The building has maintained active compliance with fire safety requirements, as demonstrated by the 2020 fire system installations and the recent permit issued in October 2024 for siding improvements to convert wood siding to new stucco. A plumbing complaint was filed in June 2020 regarding improper venting and noisy piping installation during the ADU construction, though this complaint is now listed as not active. The property has a history of addressing maintenance and safety concerns, including earlier renovation work in 2013 that encompassed unit upgrades in both Unit 1 and Unit 3 involving tile replacement and painting.

Historical records show a cluster of violations in February 2002 related to fire safety equipment and maintenance issues, including fire extinguisher recharging and combustible storage, all of which were abated by April 2002. Earlier concerns from 1997 regarding electrical issues were also addressed promptly. The building's exterior and immediate surroundings have experienced typical urban maintenance issues as documented in 311 calls, including incidents of graffiti, sidewalk parking, and street cleaning needs, though these are not directly related to building conditions or safety. The property has consistently demonstrated responsiveness to maintenance and safety requirements, with most recent improvements focusing on modernizing safety systems and upgrading living spaces.
