Augrented Insights Report

The three-story multi-family residential building at 2448-2452 Polk Street in Russian Hill, owned by Owyeung Polk LLC, was constructed in 1909 and contains 4 units. The property experienced significant maintenance issues in early 2022, with multiple housing code violations being documented between January and August 2022, including problems with heating systems, interior surfaces, and window repairs. These violations were eventually abated by September 2022, with the installation of new gas supplies and the replacement of wall heaters occurring in April 2022, suggesting improvements to the building's heating infrastructure.

Earlier maintenance history shows attention to the building's roof with reroofing work completed in 2013, though prior attempts from 1995 had expired, and another code compliance-related permit from 1985 is also documented. The building has undergone several infrastructure upgrades, including electrical code corrections completed in 2010, and more recently, multiple plumbing improvements in 2022 focused on heating systems. A notable complaint from 2020 regarding sanitation issues was filed in April 2020, though this was resolved by September 2020.

Historical records from 2003 indicate various violations including fire safety concerns and maintenance issues, though these were also resolved by 2005. Recent external maintenance issues have been primarily documented through 311 calls, with multiple reports in 2023-2024 related to parking violations and street cleaning needs. While the building has had its share of maintenance challenges, particularly regarding heating systems and interior surfaces, most documented violations from 2022 have been addressed, and recent improvements suggest ongoing attention to building systems.
