415-417 Valley St, San Francisco, CA 94131

The two-unit residential building at 415-417 Valley Street in Noe Valley, owned by Milton & Jessie Katz, is a two-story flats and duplex structure built in 1959. The property underwent significant rehabilitation in 2007 following a fire incident that caused over $30,000 in damage, with repairs completed by 2009 including substantial work on both units' interiors, bathroom remodels, and replacement of central heating units and water heaters.

This renovation period also saw the installation of new windows and patio doors in 2008, conversion from aluminum to wood composite materials, and various plumbing updates including the installation of tankless water heaters, new washer/dryer units, and electrical system improvements. More recent maintenance includes a reroofing project and driveway repaving completed in 2014, though these improvements were completed nearly a decade ago. The building's maintenance history shows attention to both interior systems and exterior elements, though there have been several sewer-related issues reported between 2010 and 2020, including multiple sewage backup incidents through a 4-inch vent line.

The property has also experienced some infrastructure challenges, including a bent street sign (2021), illegal parking issues (2025), and a hazardous materials incident (2018). While most historical complaints and issues have been resolved, the property's service records show a pattern of plumbing system maintenance requirements, particularly in relation to the sewer system, suggesting this may be an area requiring periodic attention. Recent 311 calls primarily relate to external municipal infrastructure rather than building-specific issues, indicating relatively few recent building-specific complaints.
