Initial analysis

464 31st Avenue is a two-unit residential building located in the Central Richmond neighborhood, constructed in 1969 and currently owned by David Liu and Xingping Liang. The property has undergone several significant improvements over the years, including a 2024 re-roofing project costing $13,875, and a substantial renovation in 2021 that encompassed two full bathroom remodels and kitchen updates, with an associated cost of $40,000 including extensive electrical work (installation of 30 lights, 10 switches, and various appliances). The building's history reveals a critical moment in 2006-2007 when an illegal third unit was discovered on the ground floor, leading to multiple violations and corrective measures to return the building to its legal two-unit configuration, including the removal of unauthorized kitchen facilities and the proper capping of electrical connections. This violation was officially abated in June 2007.

The property has maintained regular upkeep, with earlier improvements including a 2015 re-roofing project ($17,800) and significant modifications in 2007 that added a laundry room and converted a social room into playroom and bedrooms, along with window replacements. Recent activity shows ongoing attention to building maintenance, as evidenced by the recent re-roofing and the 2021 renovation work. The building's location has experienced recurring issues with parking enforcement, with multiple citations for driveway blocking between 2022 and 2024, though these are external to the building's management. A damaged tree incident was reported and resolved in 2022, though the city determined it was not their responsibility. The only fire incident on record was a false alarm. Overall, the building's owners have demonstrated commitment to maintaining and upgrading the property, with no active violations or complaints as of the latest records.

Risk rating

How 464 31St 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

Out of 2250 buildings in this neighborhood, 68 are predicted to be safer.
