42-48 Cornwall St, San Francisco, CA 94118

The two-story multi-family residential building at 42-48 Cornwall Street in the Inner Richmond neighborhood, owned by Hong Henry & Mee H Revoc Tr, was constructed in 1922 and contains four units. The building has undergone several significant maintenance and compliance events over the past decades, with the most serious issues arising during a routine housing inspection in July 2003 that documented multiple violations including concerns about lead-based paint, missing fire extinguishers, deteriorated exterior drainage pipes, gas utility shutoff tools, smoke detector issues, emergency exits, and handrail conditions.

These violations were all addressed and abated by September 2003. A subsequent fire safety violation regarding combustible storage was documented in September 2011 and resolved by December 2011. Historical maintenance records show a reroofing project from 1996 (now expired) and exterior wall repairs from 1986 (completed).

More recently, the building has experienced recurring sewer-related issues, with three documented sewer backup incidents between 2022 and 2024, suggesting ongoing plumbing infrastructure challenges. The property has also seen multiple parking enforcement actions for driveway blocking between 2021 and 2024, though these are external neighborhood issues rather than building-specific concerns. The most recent maintenance-related 311 calls have primarily involved external property issues such as general cleaning needs, sign problems, and street maintenance rather than internal building concerns.
