571-573 17th Ave, San Francisco, CA 94121

The property at 571-573 17th Avenue in the Central Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1916 and owned by Elaine Tong. The building has undergone several significant improvements over the past decade, with the most recent major work being sewer lateral and main line work completed in March 2022. The building has had substantial window and exterior upgrades, including the replacement of 26 windows in 2015 (13 on each floor) in non-street-facing areas, followed by more window replacements and patio door installations in 2016.

These improvements were accompanied by structural work, including sunroom bracing and replacement of footings in 2015, and exterior siding installation. The property's maintenance history shows recent concerns with the sewer system, with two sewage backup incidents reported in December 2024 from the side sewer vent, and a previous sewage issue noted in September 2021. These incidents, along with the recent sewer work in 2022, suggest ongoing attention may be required for the sewer infrastructure.

The building's exterior appears well-maintained, with major renovations completed to improve energy efficiency and appearance, including the installation of vinyl windows and upgraded siding. While there have been multiple parking enforcement calls near the property between 2019-2024, these are external issues not directly related to the building's condition. The property has a documented history of various improvements dating back to the 1990s, including kitchen and bathroom remodels, indicating regular maintenance and updates over time.
