86-88 Manzanita Ave, San Francisco, CA 94118

The two-unit residential building at 86-88 Manzanita Avenue, located in the Jordan Park/Laurel Heights neighborhood, is a two-story flats and duplex structure built in 1950, currently owned by the Hoffmark Sofia Estate. The building has undergone several significant infrastructure improvements over the past two decades, with the most substantial work occurring in 2012 when comprehensive plumbing updates were completed, including a copper re-pipe and water service line installation.

Earlier improvements include street space and sidewalk repairs in 2011, followed by a foundation replacement in 2003 which represented a major structural upgrade. The building's exterior maintenance history shows multiple attempts at window improvements, with a 1992 permit for installing five aluminum windows in the front bedroom, though this particular permit was ultimately cancelled. The property has experienced recurring issues with graffiti on the mailbox, particularly between 2016 and 2022, with five documented incidents affecting the mail receptacle, three of which were classified as not offensive and two as offensive.

All these incidents were handled through the US Postal Service Maintenance Queue system. The surrounding area has seen occasional street cleaning needs, with a documented loose garbage incident in September 2019 that was resolved through the Department of Public Works Operations. While the mailbox graffiti incidents represent a pattern of minor vandalism, they appear to be primarily surface-level issues affecting the mail receptacle rather than the building structure or systems themselves.
