322 18th Ave, San Francisco, CA 94121

The three-story multi-family residential building at 322 18th Avenue in the Central Richmond neighborhood, owned by He Haiping & Ning Ye Meng, was constructed in 1911 and contains two units. The property has undergone several maintenance and improvement projects over the years, including a significant $150,000 horizontal expansion completed in 1996, interior plaster ceiling and wall removal, and rear yard cleanup.

More recent improvements include street space work in 2019 and sidewalk repairs in 2010, both of which were properly permitted. The building experienced a sewage backup incident in February 2018 and had some tree root-related sidewalk issues in 2017, both of which were resolved. The property has a documented history of short-term rental violations, with a notice of violation issued for illegal short-term rentals through Airbnb, though this was eventually resolved with the removal of the listing.

While there have been no serious safety incidents reported, the most recent notable occurrence was a carbon monoxide detector activation (with no CO detected). The surrounding area has experienced various municipal service issues, including street cleaning matters, garbage overflow, and occasional parking violations, though these are more reflective of neighborhood conditions rather than building-specific problems. The property appears to be maintained through regular permit acquisitions for necessary repairs and improvements, though prospective tenants should be aware of the building's past short-term rental compliance issues and the potential for administrative penalties associated with such violations.
