1148-1150 Masonic Ave, San Francisco, CA 94117

The property at 1148-1150 Masonic Avenue is a 4-story, 2-unit multi-family residential building located in the Haight Ashbury neighborhood, owned by the John E Wai 1981 Living Trust and dating back to 1900. The building underwent significant renovations during 2012-2013, including a comprehensive interior remodel costing $600,000 that added multiple bedrooms and bathrooms across all floors, converted the attic into living spaces, and involved voluntary structural strengthening. Major improvements included the installation of a complete NFPA-13 fire sprinkler system throughout the building, garage, and attic (with 101 heads), window replacements, and upgrades to electrical systems.

More recent history shows recurring maintenance issues, particularly concerning water systems, with multiple complaints in 2023 regarding lack of hot water (February and June) and a significant sewer lateral replacement in 2019. The building faced several housing code violations in early 2019, including water damage, mold, and lead paint concerns, though these were abated by March 2019. A 2016 fire complaint regarding blocked exits was also resolved.

Infrastructure upgrades during 2012-2013 included new furnaces, water heaters, and comprehensive plumbing work. The property has experienced periodic issues with building cleanliness and maintenance, as evidenced by 311 calls, particularly relating to human/animal waste on nearby sidewalks in recent years. While most historical violations and complaints have been resolved, the pattern of recurring hot water issues and more recent complaints about diminished livability (July 2023) suggest ongoing maintenance challenges.
