52 Mars St, San Francisco, CA 94114

The three-unit residential property at 52 Mars Street in Corona Heights, owned by Sharon Riley Neely, is a two-story flats and duplex building constructed in 1900. The building has undergone significant maintenance and upgrades over the past few years, including a complete reroofing in 2022 (cost: $14,000), major repairs to address damage from dry-rot in 2022 (cost: $61,000), and comprehensive electrical work for an ADU installation in 2023.

A notable incident occurred in December 2021 when unauthorized construction work was reported, leading to an active building violation that was referred to a director's hearing in February 2023, though there is no current record of abatement. The property has seen multiple infrastructure improvements, including the installation of a solar PV system with battery storage in December 2022, and plumbing upgrades across various units between 2021 and 2023, though some permits were initially expired and required renewal. The building has experienced periodic tenancy turnover, with two recorded tenant buyouts in 2021 ($30,000) and 2023 ($95,000).

There have been several parking-related issues near the property, with multiple 311 calls regarding sidewalk blocking between 2021 and 2024, though most of these cases resulted in officers being unable to locate the vehicles in question. Historical records from the 1990s show repeated roofing issues, with three documented reroofing projects between 1992 and 1997, suggesting this remains an ongoing maintenance priority. The property's status as a three-unit building has been the subject of scrutiny, with planning records indicating possible concerns about work done to a rear non-conforming structure and its impact on unit count, though recent documents confirm the property has three documented residential units on record.
