15 Nobles Aly, San Francisco, CA 94133
The three-story, six-unit multi-family residential building at 15 Nobles Alley, owned by Giampaolo Boschetti and constructed in 1900, has undergone numerous repairs and modifications over recent years. Most notably, in 2024, there are current efforts to remodel the ground floor kitchen and bathroom while converting existing habitable space into an ADU unit, though this permit is still pending approval. The property has faced several maintenance and compliance challenges, including multiple plumbing and electrical upgrades, such as a 2023 fire alarm system upgrade to meet current safety standards and ongoing maintenance issues with water heaters across multiple units.
Recent complaints from 2024 indicate several active concerns, including bathroom plaster damage, unfinished bathroom work, and a potentially hazardous garage condition. Previous violations from 2018 had involved various building maintenance issues such as malfunctioning windows, light fixtures, and repairs to walls and ceilings, though these were officially abated by June 2020. The building's maintenance history shows both ongoing improvements and recurring issues, particularly with plumbing and safety systems.
Recent plumbing work in 2024 included bathtub installation in Unit 3, and earlier in 2023, there were concerns about seismic bracing and multiple violations regarding unauthorized construction work. The property has also experienced periodic fire safety inspections, with violations noted in 2015, 2016, and most recently in 2023 related to alarm systems and fire protection equipment access, though these issues were generally resolved. Infrastructure improvements have included various unit renovations, with significant work completed in Unit 2 in 2019-2020 and ongoing efforts to maintain compliance with current building codes. The building's recent history shows active management with multiple permits being filed and completed, though some recent work has generated complaints about unauthorized modifications and quality of workmanship.
