Initial analysis

The two-story, four-unit multi-family residential building at 601-607 28th Avenue in San Francisco's Central Richmond neighborhood, built in 1924, has undergone several significant renovations and improvements in recent years, with the most substantial work occurring in 2022-2023. In 2022, units 603 and 605 underwent reconfiguration and remodeling projects, including a conversion from 1-bedroom to 2-bedroom in unit 603 and from 1-bedroom to studio in unit 605, though without structural changes. This was followed by a comprehensive $50,000 interior remodel project that included kitchen and bathroom renovations, heating system updates, and room conversion work. The building's infrastructure has also seen substantial upgrades, including the installation of a tankless water heater, a new hydronic heating system, and electrical system improvements, including an upgrade to 175 amp electrical service. In 2024, however, there were two notable housing-related complaints logged regarding mold and general maintenance issues, though the specific outcomes of these complaints are not detailed in the records.

The property has a history of necessary maintenance and improvements dating back several decades, including roof replacement, window installations, and various unit renovations. Earlier renovations in 2014 involved significant work on unit 607, including bathroom additions, kitchen remodeling, and comprehensive electrical upgrades. The building has experienced relatively minor fire-related incidents, with one alarm due to malfunction and one assist to police with no civilian injuries reported. Recent maintenance activities have included water service line replacement and various system upgrades, indicating ongoing attention to infrastructure maintenance. The property has experienced recurring issues with driveway blocking, resulting in multiple parking enforcement actions between 2023 and 2025, though these are not directly related to building conditions or resident experience.

Risk rating

How 601-607 28Th 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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
