4227-4229 18th St, San Francisco, CA 94114

The property at 4227-4229 18th Street is a two-story, three-unit multi-family residential building with ground-floor commercial space, constructed in 1900 and currently owned by Lau Yuk See & Ng Chu Yuen. Over the years, the building has undergone several significant modifications, including a 2013 conversion of an eBay store to a yoga studio with ADA upgrades (cost: $35,000), along with associated plumbing and electrical work.

Roof maintenance has been performed in both 2005 and 2008, with permits issued for reroofing work totaling $7,800. The building has experienced recurring fire safety issues, with multiple fire code violations documented between 2019 and the most recent in November 2024, including problems with the alarm system, fire extinguishers, sprinkler maintenance, and emergency evacuation plans, though all violations have been marked as abated. Recent and ongoing concerns suggest attention is needed to the building's immediate surroundings, with multiple 311 calls in 2024 regarding sidewalk defects, sewer issues, and various park-related matters.

However, it's worth noting that many recent service calls relate to external conditions rather than the building itself. The property has maintained active use as a mixed-use building, balancing residential units with commercial space, though the yoga studio's impact on the local area should be considered given its change from e-commerce to fitness. The building's age and mixed-use nature have necessitated various infrastructure updates over time, though specific details regarding unit conditions or interior maintenance are not included in the available records.
