Initial analysis

The 3-unit multi-family residential building at 771-775 Union Street in North Beach, owned by Zuffo Family Revocable Trust, was constructed in 1913 and has undergone several significant renovations over the years. Most recently, in 2023-2024, the building has experienced multiple infrastructure issues, including two sewage backup incidents (October 2024 and October 2024), a water leak (October 2024), and recurring problems with tree root damage to the sidewalk that has yet to be resolved as of November 2024. In 2017, the building faced several housing violations related to heating system malfunctions, unfinished repairs, and interior maintenance issues, though all were abated by March 2017.

The property has seen notable improvements to its interior systems, including a comprehensive bathroom and kitchen renovation in 2015 costing $37,112, installation of a new wall heater in 2017, and the addition of a direct vent gas fireplace in 2016. Electrical upgrades were completed in 2016, improving lighting in hallways, closets, and bathrooms. Historical records show maintenance of essential building components, including a roof replacement in 2008 and deck refurbishment in 1985. The building has undergone routine housing inspections, with the most significant cluster of violations occurring in late 2005, addressing various safety and maintenance concerns including a damaged garbage chute, ceiling repairs, and fire safety equipment. Recent maintenance records indicate attention to basic infrastructure needs, though the recurring sewer issues and tree root problems suggest ongoing challenges with the building's exterior systems.

Risk rating

How 771-775 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.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
