2490 Chestnut St, San Francisco, CA 94123

2490 Chestnut Street is a three-story, 18-unit multi-family residential building constructed in 1928 in San Francisco's Marina district. The property has undergone several significant safety and infrastructure improvements over the past 15 years, most notably completing a mandatory soft-story retrofit in 2015 (Tier 4) valued at $100,000, which included the installation of a steel moment frame and Simpson Strong Walls. More recently, in November 2024, the building was issued a permit for the replacement of fire egress stairs in the lightwell due to significant deterioration, with an associated cost of $59,200.

The building's heating system has also received recent attention, with the installation of a new Peerless steam boiler in November 2023, following previous boiler and backflow device replacements in 2015. The property has a documented history of building safety inspections and violations, particularly between 2001 and 2006, when multiple issues were identified and subsequently abated, including problems with the fire escape system, heating requirements, and stair repairs. Regular routine safety inspections have continued, with the most recent occurring in 2016.

The building has experienced three documented fire-related incidents, though none resulted in civilian injuries. Recent 311 calls from 2022 to 2024 predominantly relate to external maintenance issues such as street cleaning, graffiti on mailboxes, and lighting concerns, rather than building-specific problems. The property's maintenance history shows ongoing attention to infrastructure updates, with multiple window installations and roofing work completed in previous decades, though some older permits have expired without record of completion.
