728-730 Bay St, San Francisco, CA 94109

The two-unit residential building at 728-730 Bay Street in Russian Hill, owned by Douglas M & Victoria M Luna, is a two-story flats and duplex structure built in 1914.

The property has undergone several maintenance and repair work over the past decade, with the most recent significant update being a furnace replacement in February 2018, which was completed successfully and involved installing a like-for-like unit with an AFUE rating of 80% and 40k BTU. In early 2017, the building experienced plumbing issues that required attention, particularly concerning the sewer system, with two separate permits being filed in February of that year - one for replacing a broken sewer housetrap, which was completed, and another for a similar repair that ultimately expired without completion.

Prior to these plumbing matters, in February 2014, there was a shoring tower installation permit issued for work at the adjacent 734 Bay Street address, though this was not subject to compliance with a specific local ordinance. While the building's maintenance history indicates regular upkeep, the 2017 sewer repairs suggest there may have been infrastructure challenges that have since been addressed, as no similar issues have been reported in recent years.
