Initial analysis

The three-story multi-family residential building at 346-348 23rd Avenue in the Central Richmond neighborhood, owned by Sumarno Santi, was constructed in 1916 and contains two units. The property underwent significant renovations in 2009, including substantial structural work with $18,000 dedicated to foundation improvements, $58,000 for remodeling multiple floors (including kitchen and bathroom updates), and the installation of new windows and front wall stucco. The electrical system received an upgrade to 200-amp service with two meters in 2007, and various plumbing updates were completed during the 2009 renovations, including the installation of a new furnace and repairs to the lightwell drain. A historical complaint from 1998 noted heating issues with the gas heater affecting kitchen and bedroom comfort, though this seems to have been resolved promptly.

More recent activity at the property includes a violation in 2019 regarding illegal short-term rentals on VRBO, which was abated after a penalty fee was paid. The building has experienced various maintenance and service calls between 2015 and 2023, including sewer issues in 2017 and multiple reports of parking violations on or near the property, though these are external to the building's condition itself. The most recent building-related incidents have primarily involved routine municipal services such as street cleaning and parking enforcement, with no recent complaints or major repairs recorded in the past several years. The extensive renovations completed in 2009 appear to have addressed many of the building's prior deficiencies, with no significant health or safety issues reported since that time.

Risk rating

How 346-348 23Rd 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.
