500-502 11th Ave, San Francisco, CA 94118

The three-unit residential building at 500-502 11th Avenue in San Francisco's Inner Richmond district is a 3-story flats and duplex structure built in 1911, currently owned by the Rong Li Living Trust. The property has undergone several significant modifications and faced various regulatory requirements over the years. Most notably, in 2018, there was a successful permit application to legalize a basement unit with 2 bedrooms and one bath, completed at a cost of $88,500.

In 1999, a rear 1-bedroom unit was added to the ground floor, establishing the building as a legal three-unit property. The building experienced safety-related issues in 2010, when multiple violations were documented regarding the rear wooden stairway handrails and guardrails, gas utility shutoff tools, and related requirements during a routine housing inspection. These violations were all resolved by August 2010 through proper repairs and permit applications.

More recently, between 2023 and 2024, there have been multiple 311 calls related to parking enforcement and sidewalk maintenance issues near the property, including reports of garbage and debris, though these are typical urban maintenance matters not specifically related to the building's condition. The building has no active fire hazards or notable fire incidents on record since a minor hazardous condition in 2006 that resulted in no civilian injuries and was closed in 2015. Historical planning records indicate various compliance matters including a request for open space reduction and issues with parking and landscaping, though these appear to have been resolved. The most recent building modifications and compliance matters suggest that the property is currently meeting required safety and habitability standards, with no ongoing violations or major structural concerns.
