233 Scott St, San Francisco, CA 94117

The three-unit residential building at 233 Scott St in Hayes Valley, owned by the Mazie Lavata Williams Revocable Trust, is undergoing significant modernization efforts following several decades of stable use. Built in 1900 as a flats & duplex structure, this single-story building (with potential additional floors from recent permits) has a complex history that includes a notable fire incident in 1996 that resulted in severe smoke damage and temporary power outages, though these issues were resolved within a month.

A comprehensive renovation project is currently under consideration, with two major permits filed in December 2022 proposing substantial upgrades, including a rear two-story addition, a new third floor with a private roof deck, reconfiguration of existing units, and the legalization of an existing cottage dwelling as an Accessory Dwelling Unit (ADU). These improvements aim to modernize the building's infrastructure and living spaces, including new window openings throughout and full sprinkler system installation.

The building's systems have seen updates in recent years, including a completed electrical upgrade in 2017 with installation of a 200-amp underground service and various electrical fixtures. While there have been several 311 calls regarding the property, these primarily relate to external issues such as parking enforcement and a past encampment situation in the vicinity, rather than building-specific concerns. A malfunctioning smoke detector activation was recorded in 2014, but no civilian injuries were reported in connection with this incident.
