Augrented Insights

Initial analysis

The property at 618-620 25th Avenue is a two-unit residential building located in the Central Richmond neighborhood, owned by Patrick Charles White and constructed in 1946. The two-story flats/duplex building has undergone several significant maintenance and compliance updates in recent years, most notably the completion of work to comply with physical inspection report #cc-8608 in September 2023, which included electrical upgrades such as GFCI installation in bedrooms, kitchen, and bathroom areas, as well as work on a separated stairs light fixture for both units. The building had a roof replacement in 2020 costing $10,000, and the furnace systems were upgraded in December 2019. A major inspection and compliance notice (CC8608) was issued in August 2023, requiring various updates to electrical systems and safety features.

The property has a history of addressing maintenance issues, including a significant cluster of violations in December 2002 that were not fully resolved until July 2009, covering problems with electrical outlets, drainage pipes, windows, stairs, and other building components. More recent concerns include multiple instances of graffiti (last reported in 2017) and a 2009 sidewalk defect issue that was eventually resolved. The building's ownership history shows two tenant buyouts: one in March 2021 for $80,000 affecting 6 tenants, and another in October 2019 involving 4 tenants. The property has maintained regular updates to essential systems, including plumbing (with a furnace replacement in 2019) and electrical systems, though the presence of historical violations and the recent 2023 inspection compliance work suggest ongoing attention to maintenance and safety requirements.

Risk rating

How 618-620 25Th 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

79th percentile

Out of 2250 buildings in this neighborhood, 472 are predicted to be safer.
