Initial analysis

The property at 615-617 20th Avenue in the Central Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1921. The building experienced significant regulatory challenges in 2005-2008, when there were violations related to the illegal ground floor unit that required multiple notifications and ultimately led to a court referral, though these issues were finally abated in 2012. The property has undergone several permitted improvements over the years, including a 1990 conversion from a single-family home to a duplex, and more recent renovations in 2008 that included exterior painting, installation of fiber cement siding, bathroom upgrades to meet plumbing code compliance, and electrical system improvements including the relocation of a subpanel and installation of new circuits.

The building's maintenance history shows periodic upkeep, particularly during the 2005-2008 period when ground floor room legalization efforts were addressed through multiple permits totaling over $35,000 in investments. More recent records from 2020-2024 primarily consist of street-related service requests and parking enforcement issues, which appear to be typical for the area and not directly related to the building's condition or management. The most recent building-related activity was a service request regarding a BSM issue in March 2024.

Risk rating

How 615-617 20Th 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
