539 Chenery St, San Francisco, CA 94131

The two-unit multi-family residential building at 539 Chenery Street in Glen Park, owned by Gordon Choi and Betty C Hong, was constructed in 1974 and is classified as a Flats & Duplex structure with one story. The building's maintenance record shows consistent attention to roof upkeep, with three documented reroofing projects: the most recent in October 2022 costing $9,800, and previous efforts in 2012 ($6,800) and 1992 (completed).

Significant mechanical system upgrades include the installation of two forced air gas furnaces in August 2019, with one rated at 60,000 BTUs and the other at 80,000 BTUs, both with 80% efficiency rating. The property has experienced a notable pattern of sanitation-related issues in recent months, with ten 311 calls between November 9, 2024, and January 12, 2025, primarily concerning loose garbage, debris, and yard waste on or around the property.

While most of these cases were resolved by city services, including some with "No Work Needed" determinations, the frequency of these reports over a two-month period suggests recurring waste management challenges in the immediate vicinity. The building's mechanical systems and roofing appear to be well-maintained based on the permit history, though the recent spate of sanitation-related calls warrants attention to the property's external maintenance protocols, particularly given the relatively recent history of garbage and debris concerns in the surrounding area.
