576-578 4th Ave, San Francisco, CA 94118

The two-unit residential building at 576-578 4th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1905, currently owned by Chuck C & Betty H Lee Revoc. The building's maintenance history shows several significant events, with the most recent notable issue occurring in late 2020 when multiple complaints were filed regarding a rotting outside vent pipe on the north side of the building, between the second and third floors.

This structural concern, which reportedly caused fallen sheet metal to enter an adjacent yard, was addressed and officially abated by September 2021. Earlier in the building's history, there was a reroofing project completed in 2005 at a cost of $7,000 and a completed code compliance matter from 1989. The property has experienced periodic enforcement actions regarding parking issues, particularly in 2023 and 2024, with numerous complaints about driveway blocking resulting in citations being issued to various vehicles.

There was also an anonymous complaint about possible illegal units in December 2017, and a fire complaint regarding illegal occupancy filed in September 2017, though these were marked as not active by December 2017. More recently, in January 2024, there was another building inspection request filed through the 311 system, though no specific details about this inspection are provided in the records. The building's age and location have historically experienced typical urban issues such as parking challenges and periodic maintenance requirements, with the most significant recent structural concern being the vent pipe problem from late 2020 through 2021.
