255 Arguello Blvd, San Francisco, CA 94118

The two-unit residential building at 255 Arguello Boulevard, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1900, currently owned by Mark Steven Marin and Yong Ye. The building's maintenance history shows several significant improvements over the years, including a reroofing project completed in 2003 costing $8,790, an underground electrical service conversion with two meters completed in 2004, and exterior improvements including siding repairs to the back of the house completed in 1996.

There was a horizontal addition permit filed in 1996, though it expired without completion, as did permits for bathroom renovations in 1994 and reroofing in 1993. Recent activity around the property has primarily involved public space issues, with multiple 311 calls in 2024 regarding illegal postings, abandoned garbage and debris, and one instance of graffiti on the sidewalk in August 2023. The property has been the subject of several management inspections related to illegal postings between February and March 2024, which were generally resolved through appropriate channels.

A fire alarm system malfunction was recorded, but no civilian injuries were reported. A notable planning application was submitted for converting the building from flats to law offices, though this was ultimately disapproved. The building's infrastructure upgrades, including the electrical service conversion and roofing projects, suggest ongoing maintenance attention to essential systems.
