22 30th St, San Francisco, CA 94110

The two-unit multi-family residential building at 22 30th Street in Bernal Heights, owned by Michael Deiner and Sulin Wang, was constructed in 1907 and has experienced several maintenance and compliance issues over its history. The property has undergone notable plumbing work, including a sewer repair completed in 2011, which coincided with the resolution of building violations related to housetrap placement and negative grading beyond the first trap, documented in April 2011. Earlier plumbing concerns emerged in 1999 when unpermitted water heater and gas work led to a temporary utility shutoff, though this issue was resolved by September 1999.

The building's maintenance record shows attention to pest control with termite repairs documented in 1998. Recent activity (2024-2025) has primarily involved external maintenance issues, with multiple reports of garbage and debris, hazardous materials, and sidewalk cleaning needs documented through 311 calls. The property has experienced some plumbing system challenges, evidenced by a sewage backup discharge in November 2024.

Historical fire incident records show three minor events: a lock-out situation, an unintended alarm system activation, and a water or steam leak, none resulting in civilian injuries. A planning record indicates a past violation regarding an illegal wind sign, though this was marked as closed with no further penalties. The absence of any tenant buyouts on record suggests stability in occupancy, while the relatively old building age and documented maintenance history suggest ongoing management of typical urban property issues.
