Initial analysis

The three-story multi-family residential building at 1172-1176 Union Street in Russian Hill, owned by Jonathan Nicols and Sh Mongey, has undergone significant improvements and renovations since 2019. The 3-unit structure, built in 1908, received comprehensive upgrades including interior kitchen and bathroom remodels with new half baths added to each unit ($125,000), window replacements (15 front-facing windows with aluminum clad wood, and 23 rear interior windows with Milgard insulated windows totaling $55,000), and infrastructure improvements such as new furnaces and ducting ($40,000). A reroofing project was completed in 2022 at a cost of $13,750, and safety upgrades included the installation of a gas fireplace and various electrical rewiring work.

The building's maintenance history shows attention to both cosmetic and structural improvements, including a routine 2011 inspection that resulted in recommendations for seismic bracing of hot water heaters. While there were several building violations noted in 2004 related to lead paint hazards, weatherproofing, damaged ceilings, and stairs, these were all abated by August 2004. More recent issues have primarily involved plumbing systems, with multiple sewage backup incidents reported between 2019 and 2024, though these were promptly addressed by PUC Sewer Operations. The property has experienced occasional issues with parking enforcement and sidewalk maintenance, as evidenced by multiple 311 calls regarding blocked driveways and garbage collection matters, but these are typical of urban environments and have generally been resolved quickly. A significant unauthorized change was noted in has to do with a removed roof deck, with planning records stating it was removed without proper permitting after 2015.

Risk rating

How 1172-1176 Union St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.
