Initial analysis

The three-unit, three-story multi-family residential building at 2130-2134 Mason Street in San Francisco's North Beach neighborhood, owned by Mason Street LLC, has undergone significant renovations and faced several challenges since its construction in 1909. The property experienced serious maintenance issues in 2013, including mold problems, plumbing leaks, electrical concerns, and a dilapidated structure, which resulted in multiple building violations that were abated by November 2013. Recent improvements in 2015-2017 included comprehensive renovations with a $54,000 project adding and remodeling bathrooms, upgrading electrical systems including three new panels, installing two high-efficiency furnaces, and replacing multiple water heaters with tankless units. A proposed ADU project in 2017 to convert a basement space into an additional unit was withdrawn, and a tenant buyout occurred in May 2017 with a payment of $78,091.95 to one tenant.

The building has undergone substantial modernization, with completed projects including kitchen and bathroom remodels, electrical upgrades, and plumbing improvements between 2015-2017 totaling over $200,000 in permitted work. There have been multiple street space permits issued between 2015-2017, though the property has also experienced periodic issues with noise, as evidenced by a 2015 complaint about excessive sound levels. The area around the building has seen typical urban issues in recent years, as shown by 311 calls for services such as sidewalk cleaning and parking enforcement, though these are general neighborhood concerns rather than building-specific issues. The property's most recent major building work was completed in 2017, and there have been no significant building violations or safety concerns since that time, suggesting improved conditions following the 2013 crisis period.

Risk rating

How 2130-2134 Mason 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.
