473 Raymond Ave, San Francisco, CA 94134

The two-unit residential building at 473 Raymond Avenue in Visitacion Valley is a single-story structure built in 1961, currently owned by Wendy Wing-sze Yeung. The property has undergone several improvements over the years, including a completed horizontal addition in 1989 and a gas house line extension in 2016. Two solar installation attempts were documented, with the 2014 installation successfully completed (24 PV modules, 6.24 kW total) while the 2015 attempt was cancelled.

The building has experienced a series of notable incidents and violations, particularly regarding fire safety systems. In September 2024, multiple fire safety violations were recorded and referred for hearing, including issues with emergency lighting, alarm system maintenance, and sprinkler service requirements. Earlier violations from 2023 involved problems with electrical workspace clearance and fire protection signage.

The building suffered minor damage in January 2021 when a vehicle collided with the structure, causing approximately 2 square feet of stucco damage near the front gate. While there have been multiple fire department responses, most have been for false alarms or smoke detector activations with no injuries reported. More recently, the property has faced several exterior maintenance challenges, with multiple 311 calls in late 2024/early 2025 regarding sidewalk defects, abandoned vehicles, and garbage issues, though many of these cases have been resolved promptly. The building's history shows a pattern of periodic maintenance issues, particularly regarding landscaping (noted in multiple fire complaints between 2020-2023), and requires ongoing attention to fire safety systems as evidenced by recent violations.
