550 Lyon St, San Francisco, CA 94117

The 550 Lyon Street property, located in Park North, is a two-unit multi-family residential building constructed in 1900, currently owned by the Hayden Bayart Family Trust. The building has undergone significant improvements over the past decades, with major renovations occurring in 2015 including comprehensive interior updates such as bathroom and kitchen remodels, laundry room conversion, window replacement, and insulation improvements, all completed at a cost of $50,000.

These renovations were accompanied by necessary electrical and plumbing upgrades, including a new 200-amp service installation with three meters and complete plumbing work for the remodeled areas. Of particular note is the property’s proactive approach to seismic safety, with a voluntary foundation replacement and soft-story retrofit completed in 2011 at a cost of $68,000, demonstrating compliance with local seismic safety ordinances. The building's recent history shows regular maintenance and responsiveness to community needs, with multiple tree maintenance requests between 2020 and 2022 being addressed, including pruning of overgrown trees that were blocking the sidewalk.

The property has experienced typical urban issues such as sidewalk graffiti (2020), abandoned Christmas tree removal (2021), and some general street cleaning matters, all of which were resolved through appropriate municipal channels. Historical records from 2011 indicate the presence of hazardous materials requiring cleanup and a pavement defect issue, though these appear to be one-time incidents from over a decade ago. The property's maintenance record suggests regular upkeep and responsiveness to both building and neighborhood needs, with no recent major structural or safety concerns reported.
