639-641 Kirkham St, San Francisco, CA 94122

Located in San Francisco's Inner Sunset neighborhood, 639-641 Kirkham Street is a two-unit, two-story multi-family residential building constructed in 1922, currently owned by the Shu Kuen Tam Revocable Trust. The building has experienced several significant maintenance and compliance issues over the past two decades.

In 2019-2022, there were multiple sewer-related incidents, including a sewage backup in July 2017, and both sewer service requests and pavement defects in 2018 suggest ongoing infrastructure challenges. A notable incident occurred in June 2023 when a car detailing business operated from the property, using mechanical equipment daily until mid-July, which raised concerns about neighborhood disruption. The building's compliance history includes a significant violation in 2010 when unauthorized bathroom remodeling work prompted a complaint (201034406), though this was resolved within weeks.

Termite repairs were completed in 2009 at a cost of $8,150, and some historical permits show past improvements, including reroofing (1999) and bedroom window installations (1982). Street-related issues have been documented through various 311 calls, including waste management concerns, though these are more indicative of general neighborhood conditions rather than building-specific problems. While the building's major structural systems and infrastructure have required various repairs and maintenance over the years, most recent issues have been related to unauthorized modifications and temporary business operations rather than fundamental building safety concerns.
