Initial analysis

The two-unit residential building at 843 46th Avenue in the Outer Richmond District, owned by Boris Dinerman and Eleonora Ula, has experienced several notable events since its construction in 1947. The building underwent significant modifications between 1989 and 2000, including ground floor remodeling, children’s room improvements, stair reconstruction, and dry rot repairs. A concerning episode occurred in 1996 when a complaint was filed regarding an unauthorized kitchen and shower installation, which was related to a possible illegal unit lacking proper ventilation. This same period saw additional complaints about construction activities in the basement area near newly built stairs, though this was quickly addressed within a few days.

More recently, in 2023-2024, the property has faced multiple infrastructure and maintenance challenges, primarily related to external factors such as tree management, sidewalk maintenance, and parking issues. There have been documented problems with trees impacting property and sidewalks, along with several instances of driveway blocking that required enforcement attention. The building's fire safety record shows two incidents, one related to electrical wiring issues and another false alarm, though neither involved civilian injuries. Recent municipal service calls have primarily concerned external maintenance matters, including catch basin maintenance, street cleaning, and vehicle-related issues, indicating a pattern of routine urban infrastructure challenges rather than building-specific problems. The property has not had any major building violations or safety concerns in the past decade, with all recent service calls being properly addressed through normal municipal channels.

Risk rating

How 843 46Th Ave'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

Out of 1040 buildings in this neighborhood, 582 are predicted to be safer.
