43-45 Diamond St, San Francisco, CA 94114

The property at 43-45 Diamond Street is a two-unit multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood. Built in 1914, this two-story flats and duplex structure is currently undergoing significant improvements, with recent permits issued in November 2023 for converting an existing family room and bedroom into a new ADU on the first floor, including the addition of a kitchen and conversion of a half bath to a full bathroom, at a cost of approximately $49,000. This project is proceeding concurrently with plumbing and electrical work in late 2024, including the installation of a tankless water heater, a new shower and kitchen facilities, and associated electrical components.

The building has undergone several substantial improvements over the years, including the installation of an elevator in 2019, which included electrical work completed in April 2019. Previous maintenance issues were addressed through repairs to a dry rotted deck in 2018, following a 2017 permit for both elevator and deck construction. Historical permits from 2003 show completed work on basement remodeling and kitchen renovations.

The property has experienced some urban maintenance challenges, with multiple 311 calls in 2023-2024 related to street cleaning issues, including reports of waste and garbage. Parking enforcement has been required on several occasions in 2023 for vehicles blocking driveways or parking on sidewalks. While there have been some quality of life issues reported via 311 calls, such as graffiti (2022) and instances of waste that required attention (2019-2024), these have generally been resolved through appropriate city services. The building's recent and ongoing improvements suggest active maintenance and modernization efforts by the current owner, Thanh K Phan Revocable Lvg.
