69-71 Walter St, San Francisco, CA 94114

The three-unit residential building at 69-71 Walter Street in the Duboce Triangle, owned by Nelson/noyon Living Trust, is a three-story flats and duplex structure built in 1904. Since the early 2000s, the property has undergone several significant improvements, including a complete reroofing in 2005 ($7,850), the reconstruction of rear stairs in 2002 ($12,600), and substantial basement work in 2011 including concrete slab installation ($4,000), beam-to-column connections ($800), and new partition walls ($2,000). Most notably, a complete sewer line and house trap replacement was completed in September 2012, suggesting attention to maintaining essential infrastructure.

The building's permitting history indicates regular maintenance and structural improvements, with no major renovations or violations recorded in recent years. The property has experienced typical urban incidents over the years, with the most recent issues being general service requests and illegal postings in early 2024. A construction noise complaint was recorded in April 2021, though this was transferred to the appropriate department for tracking.

Historical records show a routine housing inspection from 2002-2009, which is no longer active. While there have been various sanitation and maintenance-related 311 calls, including reports of loose garbage and a medical waste incident in 2014, these appear to be general neighborhood issues rather than problems specific to the building. The building's recent history shows no recurring maintenance issues or significant safety concerns, with the last major infrastructure work (sewer replacement) being completed approximately 11 years ago.
