640-646 Douglass St, San Francisco, CA 94114

The property at 640-646 Douglass St is a two-story, four-unit multi-family residential building located in Noe Valley, built in 1904 and currently owned by Richard Carpeneti Trustee. The building has experienced several significant maintenance and safety issues over its history, with the most recent being multiple fire code violations documented in November 2024, related to alarm systems and sprinkler service requirements.

This follows a pattern of fire safety concerns, with similar violations recorded in September 2023, 2020, 2019, and 2009. The building is currently undergoing reroofing work, with permits issued in January 2025 for shingle replacement at a cost of $16,500, following previous roofing work completed in 1997 and another roofing permit from 2025. The property has a documented history of building safety and maintenance issues, including multiple violations and repair requirements identified during routine inspections in 2001 and 2011, which included concerns about lead paint hazards, staircase repairs, handrail repairs, and security improvements.

A notable tenant buyout occurred in August 2017 at 644 Douglass Street, involving two tenants and totaling $3,550. The building's maintenance record shows consistent attention to infrastructure updates, though the recurring fire code violations suggest ongoing challenges with fire safety compliance. Recent 311 calls from the last year primarily relate to street-level maintenance issues outside the building, including garbage and debris concerns, and parking-related complaints.
