1501 20th St, San Francisco, CA 94107

The 4-unit multi-family residential building at 1501 20th Street in Potrero Hill, built in 1912 and currently owned by Leung Bambuda & Dolezal Deb, has undergone significant maintenance and improvements over recent years. The most recent work, completed in August 2023, involved window replacements on the street-rear facade, following similar window upgrades in 2021 when 12 windows were replaced, primarily street-facing. The property has received substantial roof-related maintenance in 2021, including complete roof replacement (2200 sq ft) with new plywood and materials, along with brick and dry rot repairs to the facade and exterior wall. Other notable improvements include a comprehensive kitchen and bathroom remodel in 2017, plumbing updates including water heater replacement, and various electrical upgrades including panel installation and circuit work.

Historical issues from 2005-2006 involved multiple building violations that were subsequently resolved, including problems with ceilings, windows, doors, siding weatherproofing, stairs, and fire safety concerns. Since then, there have been no active violations, and the building has undergone regular safety inspections. Recent maintenance records show ongoing attention to building upkeep, with proper responses to infrastructural needs. The property has experienced occasional issues with street cleaning and waste management in the vicinity, as evidenced by multiple 311 calls in 2023-2024, though these are external to the building itself.

A notable health and safety incident, a carbon monoxide situation, occurred at some point but resulted in no civilian injuries. Recent building improvements (2021-2023) focus on maintaining and upgrading the property's exterior and systems, with particular attention to weatherproofing, drainage, and structural elements. The substantial investment in roof maintenance and window replacements suggests proactive management of the building's infrastructure. While historical building violations were significant at one point, they were addressed and resolved, and there have been no similar issues in recent years. The property's maintenance pattern shows regular upgrades and repairs, with no major safety or habitability issues reported in recent inspections.
