1440-1450 Washington St, San Francisco, CA 94109
The 22-unit, 4-story apartment building at 1440-1450 Washington Street in Nob Hill, owned by Washington Mews LP, was constructed in 1911 and is undergoing significant upgrades to its facilities. Most notably, in 2021-2022, the building completed important safety improvements including fire alarm system upgrades with low-frequency sounders and monitoring radios, representing a $21,000 investment, along with substantial kitchen and bathroom renovations in multiple units (Apts 1, 5, and 3) totaling over $78,000. The property has also achieved its mandatory Soft Story retrofit compliance as a Tier 2 building.
The building's maintenance and upgrade history shows regular attention to both individual units and building-wide systems. Recent improvements include plumbing upgrades in multiple units, electrical system upgrades, and maintenance of essential services like heating. The property has experienced periodic fire alarm system issues (2017-2022) which were all corrected, and there were historically some heating and fire safety violations from 2001-2010 that have since been resolved.
In 2023, the building applied for permits to convert the basement into two additional dwelling units, potentially increasing its total to 25 units, though prior attempts for this modification had been withdrawn. While there have been several complaints and 311 calls regarding various services (mostly external to the building), including parking enforcement and street cleaning, these have generally been resolved promptly and do not reflect on the building's internal conditions. The building's location has seen several sidewalk and street-related issues as documented in 311 calls, particularly regarding abandoned vehicles and street cleaning concerns, though these are external to the building itself. The property's maintenance record shows consistent investment in both unit upgrades and building systems, with most recent works focusing on modernizing individual units while maintaining building-wide safety and infrastructure improvements.
