433-435 31st Ave, San Francisco, CA 94121

This three-story, two-unit multi-family residential building located at 433-435 31st Ave in the Central Richmond neighborhood was constructed in 1992 and is currently owned by Guo Li Bao. The building underwent significant construction activity during its initial year, 1990, when multiple safety features were installed, including a sprinkler system in the basement, a new front stair reconstruction, and fire escape modifications, all of which were successfully completed.

The 2000s saw further improvements, including window replacements and front stair renovations, though the latter permit has since expired. In recent years, the property has faced recurring noise issues, with three noise complaints recorded between 2017 and 2020 regarding amplified sound electronics, though all were closed with accepted summaries.

The building has also experienced periodic issues with street maintenance, with multiple reports of loose garbage and sidewalk cleaning needed between 2009-2013, and there was one instance of graffiti on the sidewalk in 2009. Some planter boxes and sidewalk obstructions were noted in a 2013 cleaning report, with follow-up research suggested for possible citation. While these historical records suggest occasional maintenance challenges, most of the original construction work was completed successfully, and the property has had no major safety incidents reported in recent years.
