3750-3752 16th St, San Francisco, CA 94114

The property at 3750 16th Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by 606804 Ontario Limited. The building has undergone several significant repairs and improvements over its lifetime, most notably a major renovation in 1986 that included the addition of a garage, a penthouse "lantern," and remodeling of kitchens and bathrooms.

The most recent permitted work, in April 2024, involves the installation of a wood retrofit window on the street-facing side of the building, with a reported cost of $4,494. The property has experienced recurring sewer-related issues, with multiple incidents reported between 2019 and 2021, including sewage backups and a sewer vent problem documented in September 2021, which required approximately 8 feet of spot repair work on the sewer main with house trap. This pattern of sewer problems, though somewhat resolved, suggests an ongoing infrastructure challenge.

Noteworthy recent events include three reports of pavement-related issues in late 2023 and 2024, although these were primarily parking enforcement matters rather than building-related concerns. The building's maintenance history shows attention to structural updates, particularly in recent years, with the installation of new windows and the 2021 sewer repairs representing significant infrastructure improvements. The property has also experienced several instances of abandoned vehicles in the vicinity between 2018 and 2024, though these external issues do not directly impact the building's condition or resident experience.
