61-63 28th St, San Francisco, CA 94110

This two-unit, two-story multi-family residential building, located at 61-63 28th Street in Noe Valley, was constructed in 1909 and is currently owned by Rodriguez Concepcion B & Ru. The property has undergone several significant improvements over the past decade, most notably the installation of a solar system in 2016 comprising two sets of 9 PV modules (2.565 kW DC), and more recently, the replacement of both the water heater systems with modern units in 2024 - a gas tankless to tankless conversion and the installation of a new heat pump water heater.

The building has experienced recurring sewer issues, with three documented sewage backup incidents between 2020 and 2023, suggesting potential ongoing plumbing infrastructure challenges. A shower-to-tub conversion was completed in 2017, along with various maintenance and improvement work including reroofing in 2001 (permit expired) and the use of street space in 2016. The property has faced several maintenance and environmental challenges, including a complaint in 2016 regarding paint chip debris during building sanding, and multiple reports of garbage and debris in 2024, though these may have been related to external factors rather than building maintenance.

Earlier tree-related concerns in 2020 regarding an overgrown and dead tree were noted, with the city taking responsibility for street tree maintenance under the StreetTreeSF program. While the building's systems have received updates, particularly in terms of solar energy and water heating, the recurring sewer issues and some maintenance complaints indicate areas requiring attention. The property's building and plumbing permits suggest a relatively active history of improvements, with a particular focus on modernization and energy efficiency upgrades in recent years.
