Initial analysis

The property at 618-620 22nd Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1922, this flats and duplex structure has undergone several significant renovations and faced some notable challenges over its history. The most substantial recent improvement was a comprehensive third-floor kitchen and bathroom remodel completed in 2014, which included the installation of new countertops, cabinets, plumbing fixtures, electrical systems (40 receptacles, 8 circuits, etc.), and various appliances, costing approximately $32,000. The building suffered a serious issue with fire damage in late 2006, requiring extensive repairs in 2007 to address damaged areas including exterior siding, framing, electrical systems, and HVAC - these repairs were significant, costing around $30,000.

More recently, in 2019, there were two complaints filed regarding potential unauthorized modifications to the building, including allegations of illegal unit construction and electrical work performed without proper permits. These complaints, which were not actively pursued in the system, were filed in May 2019 and suggested concerns about work beyond permitted scope and unapproved dwelling units. The building's earlier history includes some unsuccessful attempts to convert it to a two-family dwelling in 1983, and while records show a reroofing project from 1995, this permit has since expired. The proper maintenance of life safety systems has been addressed through various permits, including a fire safety compliance completion in 1984.

Risk rating

How 618-620 22Nd 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.
