Initial analysis

The property at 546-548 41st Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1927, currently owned by Joan A. Nitis. The building has undergone several significant improvements over the years, with the most substantial renovation occurring in 2009, when approximately $22,000 was invested in upgrading the second-floor kitchen, including new cabinets, flooring, and windows, along with associated electrical and plumbing work. This renovation included the installation of new electrical systems with 100-amp service for both units, a 60-amp subpanel, and complete plumbing updates. Earlier maintenance records show a reroofing project completed in 1993 and stair repair work in 1989.

The building has experienced recurring parking issues in recent years, with multiple complaints about blocked driveways between 2021 and 2024, though all these cases were ultimately resolved through enforcement action. There was also one report of hazardous materials on the street in November 2021 which was addressed. More recent incidents include an August 2024 sewer-related issue requiring private contractor intervention, and a driveway blocking complaint in October 2024 that could not be verified by responding officers. The property's permit and maintenance history suggests regular upkeep, with no recorded structural issues or safety violations affecting resident experience.

Risk rating

How 546-548 41St 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.
