727-731 Waller St, San Francisco, CA 94117

The 727-731 Waller Street property is a three-story, 6-unit multi-family residential building located in Hayes Valley, constructed in 1900 and currently owned by the 1993 Kellerman Family Trust. The building has undergone several significant improvements in recent years, most notably completing a mandatory soft-story retrofit in 2019 at a cost of $35,000, bringing it into compliance with seismic safety requirements as a Tier 3 building. Other notable recent improvements include a gas line replacement in 2011, and the installation of low-frequency sounders in 2020.

The building has a documented history of proper maintenance and upgrades, including a kitchen and bathroom remodel in 2012 that included extensive electrical work and plumbing updates. The property has experienced some issues in the past, particularly in 2002 when multiple fire safety violations were recorded, including problems with combustible storage, fire extinguishers, dryer ventilation, and the central alarm system, though these violations were all abated by December 2002. While there have been three documented gas-related incidents (two gas leaks and one carbon monoxide detector activation with no CO detected) according to fire incident records, there were no civilian injuries reported in any of these incidents.

The building has undergone routine housing inspections in 2002 and 2009, with no active violations currently on record. Recent external maintenance has included responses to various 311 calls regarding street conditions, though these are primarily related to sidewalk maintenance and public space issues rather than building-specific concerns. The most recent building-related complaint as of October 2024 involves a missing side sewer vent cover, which remains open.
