Initial analysis

The property at 831-833 30th Ave is a two-unit, two-story multi-family residential building located in the Central Richmond neighborhood, constructed in 1947 and currently owned by To Living Trust. The building has undergone several significant improvements over the years, most notably a completed ground floor rear addition in 2009 valued at $55,000, which included electrical work for lighting and receptacles completed in 2011. Other improvements include the installation of eight new wood and clad windows in the front of the building in 2006, and a 200-amp electrical service upgrade completed in 2008.

The building's history includes one notable complaint filed in September 2008 regarding unauthorized building and remodeling work on multiple floors, though this complaint was marked as abated by December 2008. The property has generated minimal neighborhood service calls, with only two parking-related incidents recorded: a driveway blocking complaint in February 2020 that resulted in an officer response but no action taken, and a report of an abandoned vehicle in December 2014, which was resolved when the vehicle was no longer present upon arrival of officers.

Risk rating

How 831-833 30Th 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.
