2700-2702 Diamond St, San Francisco, CA 94131

The two-unit residential building at 2700-2702 Diamond Street in Glen Park, owned by Jeffery & Diane Cerf 2002 R, is a 2-story flats and duplex structure built in 1962. The property underwent significant improvements in 2011, including the installation of 18 energy-efficient vinyl windows, a kitchen remodel in unit 2702, and the removal of an unauthorized lower-level studio and deck. This renovation period also involved correcting building violations from 2010 regarding unauthorized unit modifications, including the removal of interior stairs and bay windows.

Infrastructure upgrades included replacing two heating systems, rewiring bedrooms, relocating utility meters, and upgrading the electrical service from 100 to 200 amps. More recently, in the last quarter of 2024, the building has experienced several maintenance issues requiring attention, including sewer-related problems (both a backup and tree root damage), a missing side sewer vent cover, and some environmental concerns such as garbage debris and overgrown trees. A tenant buyout occurred in December 2024 at a neighboring address (2714 Diamond Street) involving two tenants and a payment of $55,925, though this is not directly related to the subject property.

The building's maintenance history shows a pattern of addressing compliance issues and upgrading systems, particularly during the 2011 renovation period. Recent maintenance concerns primarily involve sewer infrastructure and exterior maintenance, with multiple 311 calls related to these issues in late 2024. The property appears to have maintained compliance with building codes since the major renovation and correction of violations in 2011, though the recent sewer maintenance issues suggest ongoing infrastructure challenges. The most recent significant infrastructure upgrade on record was completed in 2011, and there are no current open building violations as of October 2023.
