Initial analysis

The Lo Family Trust Of 2003 property at 471 31st Avenue in the Central Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1989. The building has undergone several significant modifications and faced regulatory challenges over the years, with the most notable recent work occurring in 2016 when the rear of the building received new siding and vinyl windows, though this work initially proceeded without proper permits or inspections, leading to violations that were eventually abated by September 2016. Other recent improvements include a bathroom cabinet and sink replacement in 2016, and previous work from 1992 to 1996 involved various window and skylight replacements, with some proposed projects such as a rear platform enclosure and greenhouse window installation being cancelled.

The property has experienced recurring issues with unauthorized modifications, as evidenced by multiple building complaints in 2016 regarding unpermitted window and siding work, as well as unauthorized kitchen remodeling with electrical and plumbing work. These violations, while ultimately resolved, indicate a pattern of initial non-compliance with building regulations. More recently, there have been numerous parking-related incidents near the property, with multiple citations issued for driveway blocking between 2023 and 2024, suggesting ongoing challenges with street parking management in the vicinity. The building has also experienced three documented fire incidents, though none resulted in civilian injuries, with incidents including contained cooking fires and smoke removal situations.

Risk rating

How 471 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
