1770 Hayes St, San Francisco, CA 94117

The two-unit residential building at 1770 Hayes Street in Park North is a century-old flats and duplex structure owned by the Charles Sterck Trust. The property has undergone several significant structural and maintenance work over its history, including foundation raising and dry rot repairs in 1986, kitchen and bathroom renovations in 1987, garage repairs including brick and stucco work in 1991, and most recently, furnace replacement in 2011.

The building experienced multiple maintenance-related service calls in 2020-2024, with the most concerning being a sewage backup issue reported in November 2023 that was resolved by field work. Other recent incidents include two separate graffiti incidents in 2021 and 2020, both of which were cleaned by city crews.

The property has faced various neighborhood management challenges, including reports of illegal postings in September 2020, sidewalk parking complaints in April 2019, and multiple service requests related to street cleaning and debris in late 2024. While the building's structural issues appear to have been addressed through various permits, the frequency of recent service calls related to exterior maintenance and neighborhood concerns suggests ongoing attention to building peripheries may be required.
