Initial analysis

The property at 731 31st Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1932 and currently owned by the Gin 2018 Family Trust, this flats and duplex style building has undergone several significant improvements over the past few decades. Most notably, the building has seen substantial solar energy upgrades, with multiple installations between 2018-2022, including a 3.95 kW system with 10 roof-mounted panels and main panel upgrade from 100A to 200A in 2022. Earlier solar-related work in 2018 involved installing 16 PV modules with total ratings varying from 250W to 300W. Other improvements include a water heater replacement in 2011 and the addition of a subpanel in 2018.

The building's maintenance history shows attention to structural and safety issues, including termite treatment in 1986 and a building compliance update in 1985, though the latter permit has since expired. A rear deck addition was proposed but specific details on its completion are not readily available from the records. The property has experienced some infrastructure challenges, including a sewage backup issue in 2017 that was resolved, and there have been several 311 calls related to street and sidewalk conditions nearby, including reports of hazardous materials (glass), general cleaning needs, and parking violations. While most of these external issues were resolved promptly, they indicate ongoing attention to the building's surrounding environment. The property appears to have been maintained with regular updates to keep up with modern requirements, particularly with respect to energy efficiency improvements through solar installations.

Risk rating

How 731 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.
