2516-2518 Sutter St, San Francisco, CA 94115

The two-unit residential building at 2516-2518 Sutter Street in Lower Pacific Heights is a two-story flats and duplex structure built in 1900, currently owned by the Elouise H Mayo Living Trust. The property has undergone several significant maintenance and improvement projects over the past decade, most notably the development of an accessory dwelling unit (ADU) at grade level, which was filed in October 2019 under ordinance #162-16, though the status remains filed without a completion record.

The building experienced a cluster of plumbing and safety issues in 2011, including violations related to an improperly installed furnace and flue system in the crawl space, inadequate clothes washer standpipe venting, and improper dryer exhaust systems, all of which were resolved by October 2011 through various permits and corrections. Additional plumbing work completed in 2011 addressed multiple infrastructure upgrades, including water line replacement, laundry drain improvements, and exhaust flue corrections. The property has undergone several other maintenance projects, including a reroofing project in 2011 costing $8,500, and a gas line and heater modification in 2013, though that permit has since expired.

More recently, there have been minimal issues reported through 311 calls, with the most recent being a general cleaning request in March 2023 and a tree-related property damage concern in August 2017, though the latter case was deferred to a scheduled maintenance timeline by city authorities. While the building has had its share of plumbing and safety violations in the past, all of the known issues were addressed and resolved within reasonable timeframes, with no active violations currently on record. The property's most recent significant improvement, the proposed ADU development, remains in a filed permit status without further listed updates or completion verification.
