157 Saturn St, San Francisco, CA 94114

The two-unit, two-story residential building at 157 Saturn Street in Corona Heights, owned by Werner M. Blumer, has a documented history of structural and plumbing issues spanning several decades since its construction in 1926. The property has undergone multiple foundation-related work, with the south-west corner raised in 1986 and additional work completed in 1993, though an earlier permit from 1988 for foundation work is noted as expired.

More recent plumbing infrastructure improvements include a gas houseline extension completed in 2013 and sewer repairs completed in 2009 following a notable incident where dyed sewer water leaked into a neighbor's property. The building experienced significant maintenance challenges around 2013-2014, with multiple violations issued for interior surface damage, including compromised ceilings, water damage, and concerns about roof deck waterproofing, leading to designation as a "nuisance" property under San Francisco Health Code Section 1001-d. These violations were eventually abated in January 2014.

A persistent drainage issue was documented in 2014, with complaints about an ineffective drainage grate that led to water pooling affecting neighboring properties. The property has also generated multiple 311 calls regarding abandoned vehicles in the vicinity between 2022 and 2024, though these are unrelated to the building's condition and primarily concern street parking issues. While the building's historical record shows periods of maintenance and repairs, particularly regarding its foundation and plumbing systems, the concentration of violations and complaints in 2013-2014 suggests a period of significant maintenance challenges that were subsequently addressed.
