517-521 Vallejo St, San Francisco, CA 94133

The Vallejo Street property is a 6-unit, 3-story multi-family residential building constructed in 1913 in the Telegraph Hill neighborhood, currently owned by Vallejo Street Partners LLC. The building has undergone significant recent improvements, including a completed fire alarm system upgrade in 2023 (cost: $38,613) to comply with San Francisco Fire Code requirements. Between 2021 and 2022, major renovations were completed including kitchen and bathroom remodels ($26,000), the installation of new 27 windows ($45,000), and rewiring of an entire unit.

The property successfully completed mandatory seismic retrofitting in 2016, achieving Tier 3 compliance. Recent maintenance concerns have centered around sewer issues, with multiple sewage backup discharge incidents reported between August and November 2024, particularly involving the side sewer vent. Historical records show past plumbing issues in 1999 regarding sewage leakage between the property and a neighboring building.

The building faced several safety compliance issues in 2000, including violations related to fire protection systems and egress obstructions, though these were all abated by 2014. Additional improvements include water heater relocations (2008), various plumbing upgrades, and electrical system enhancements. The property has undergone routine inspections over the years, with the most recent fire alarm system modifications in late 2023, demonstrating ongoing maintenance and adherence to safety requirements.
