70 Russell St, San Francisco, CA 94109

The two-unit multi-family residential building at 70 Russell Street in Russian Hill, owned by Tony Eng & Shaw Kim Lee Rev, is a two-story flats and duplex structure built in 1916. The building has experienced recurring sewer-related issues over recent years, with three documented incidents between 2017 and 2024 involving sewage back-ups from vent systems, with the most recent occurrence in November 2024 being officially resolved by PUC Sewer Operations.

Of particular note is a concerning planning record indicating a dwelling unit merger of the building's two units into one, though both units reportedly still retain individual mail and power meters, with no official record of this conversion from two units to one. The building's maintenance history includes a significant exterior repair in 2005 when damaged redwood siding was replaced and painted, a project completed at a cost of $3,000.

While the permits and 311 call records show some basic maintenance and service requests typical of a building of its age, the pattern of sewer issues constitutes the most notable ongoing infrastructure challenge. The building's documented history spans from the early 1980s through the present, though detailed records from earlier decades are limited.
