308 Duncan St, San Francisco, CA 94131

The three-unit, three-story multi-family residential building at 308 Duncan Street in Noe Valley, built in 1900, has undergone several significant renovations and safety upgrades in recent years under the ownership of 437 Duncan St LLC. The property, consisting of flats and duplex units, has seen substantial improvements including the installation of a comprehensive fire sprinkler system throughout the building in 2019-2020, and a complete fire alarm system upgrade in 2021-2022 featuring new low-frequency sounders and smoke detection equipment.

Major renovation work was performed in 2017-2018, including an expansion of the front top floor unit, relocation of the rear unit, and addressing multiple safety concerns regarding the front porch and rear stairs, which had previously generated several building violations and complaints regarding dry rot and structural issues. The building's recent history shows a pattern of both proactive improvements and ongoing challenges. In addition to the fire safety upgrades, the property underwent significant plumbing and electrical work between 2020 and 2022, including the installation of a new radiant heating system and multiple unit remodels featuring new kitchens and bathrooms.

However, there remains an active complaint regarding the roof deck constructed over the garage in 2020, with concerns about neighbor notification and noise impacts. Historical issues from 2016 regarding water intrusion and plumbing leaks have been resolved, and the building underwent routine inspections in 1999 and 2008 that did not result in identified violations. Recent permits also indicate ongoing maintenance and improvement efforts, including repairs to the front porch and rear staircase systems to address previous safety concerns.
