Augrented Insights Report

The 226-228 Irving Street property is a two-story, three-unit multi-family residential building located in San Francisco's Inner Sunset neighborhood, built in 1908 and owned by Iris L H Tam. The building is currently facing significant safety and maintenance issues, most notably an active complaint from August 2023 regarding the continuous lack of electricity in all common areas (stairwells, hallways, garage, front entrance) following the landlord's cancellation of the PG&E account.

The building has multiple active violations from 2022 that remain unresolved, including issues with stairs, fire safety equipment (fire extinguisher charge/tag), and the need for carbon monoxide and smoke alarm affidavits. A serious concern is the building's non-compliance with the Mandatory Soft Story Retrofit Program requirements, with the most recent permit from 2017 showing work valued at $54,000 for seismic retrofit work.

Other notable historical issues include a sewerage backup problem from 2022, drainage pipe issues, and multiple routine inspections revealing various building code violations. The property has also experienced recurring plumbing problems, including a clogged shower and kitchen wall leak in 2009, and there were concerns about roof disrepair and broken windows in 2010. Recent activity at the property has generated multiple 311 calls in 2024-2025, primarily related to parking enforcement issues on the sidewalk and at driveways, though these are not directly related to building habitability concerns.
