Initial analysis

The property at 366 25th Avenue is a two-story, 6-unit multi-family residential building located in San Francisco's Central Richmond neighborhood, owned by Albert Ko and constructed in 1964. The building has undergone several significant improvements and maintenance work over the years, most notably completing a mandatory seismic retrofit of its soft-story structure in 2015 at a cost of $60,000, followed by reroofing work in 2020 ($12,800), and the replacement of 20 linear feet of sewer line in 2022. The building has a documented history of sewer-related issues, with multiple sewer backup incidents reported between 2021-2022, culminating in a 2022 violation regarding a defective house trap and/or sewer lateral that created health concerns (abated September 2022).

The property experienced a serious incident of fire damage in 1998, which was subsequently repaired. A significant cluster of fire safety violations was recorded in January 2004, including issues with the fire escape drop ladder, combustible storage, and the need for fire sprinklers, though all these violations were resolved by May 2004. Recent maintenance activities include addressing garbage and debris issues on the surrounding streets (most recently in 2024) and responding to multiple sewer backup incidents through 2021-2022. The building's maintenance record shows regular updating of essential systems, though the pattern of sewer-related issues suggests this remains an ongoing concern, as evidenced by multiple 311 calls regarding sewage problems between 2021-2022, with the most recent sewer work completed in August 2022. The building's soft-story retrofit (designated as Tier 3 with work completed and CFC issued) demonstrates compliance with modern seismic safety standards, representing a significant safety improvement.

Risk rating

How 366 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
