134-136 17th Ave, San Francisco, CA 94118

The property at 134-136 17th Avenue is a two-unit, two-story multi-family residential building located in the Lake-The Presidio neighborhood, owned by the Marian S. Chin Revocable Trust and constructed in 1913. The building underwent significant renovations and improvements over recent years, notably including the addition of a ground-floor ADU (Accessory Dwelling Unit) in 2020-2021, which involved comprehensive work including kitchen and bathroom additions, fire sprinkler system installation, and associated electrical and plumbing upgrades.

In 2019, substantial renovations were completed on multiple floors, including kitchen and bathroom remodeling, bedroom additions, and foundation work. The building's infrastructure has seen considerable investment, with the most recent work in 2023 including a new 200-amp electrical service with multiple meters, and previously in 2019 with the relocation of gas furnaces for each unit. The property has a documented history of sewer-related issues, with six sewage backup incidents recorded between 2018-2021, primarily involving 4-inch vents, though these were resolved through service interventions.

In 2015, the building faced significant challenges with lead paint hazards and water damage, leading to violations that were subsequently abated by December 2015 through proper remediation measures. Other maintenance work included roof replacement in 2015 and repairs to a common area staircase. The building's recent improvements suggest active management and investment in maintaining and modernizing the property, though the recurring sewer issues remain a notable concern in its maintenance history.
