Initial analysis

The property at 1423-1425 47th Avenue in San Francisco's Outer Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1974, currently owned by Zoya Kogan Survivor's Trust. The building experienced significant regulatory issues in late 2005 when multiple violations were documented regarding unpermitted modifications, including unauthorized bathroom and kitchen installations in the basement and ground floor, which were not in accordance with official building records that classify the structure as a two-unit building. These violations led to abatement proceedings and required the installation of proper permits under violation numbers 200564239 and 200564534, with compliance work including interior stairs, bathroom renovation, and additional first-floor rooms completed in 2006 at a cost of $12,000. The electrical system has undergone notable upgrades between 2007-2008, including the installation of a 200-amp service panel and comprehensive electrical work throughout the property, though with explicit notes that residential space heater installations were not included in the scope of work.

More recent history of the property shows relatively minor issues, with the most recent documented concerns being parking-related (a driveway blocking incident in 2020) and tree maintenance requests in 2017. A side sewer issue was reported and addressed in 2009. All major violations from 2005-2006 have been recorded as abated, and the building currently operates under its designated multi-family residential classification. The extensive documentation from 2005-2006 regarding unauthorized modifications and subsequent compliance actions suggests a period of significant regulatory scrutiny, though these issues appear to have been resolved through proper permitting and construction work.

Risk rating

How 1423-1425 47Th 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.
