Initial analysis

The two-unit residential building at 730 20th Avenue in San Francisco's Central Richmond neighborhood is a 1922 flats and duplex structure currently owned by Louie Frances. The property has undergone several significant improvements in recent years, most notably in early 2023 when comprehensive renovations were completed to remodel both kitchens in the residential units, including the installation of new boilers and electrical systems for the kitchens and laundry rooms, with the total investment in these upgrades amounting to approximately $70,000. Prior to this, in late 2022, both units received new boilers with 150,000 BTU capacity, replacing the old units. The building's maintenance history shows attention to basic infrastructure, including side stairway repairs for dry rot in 1999, and various kitchen improvements dating back to 1988, though some of these earlier permits have since expired or were not completed.

The property's more recent history shows one resolved 311 call from November 2024 regarding garbage and debris, though this was related to street conditions rather than the building itself. An earlier issue from 2016 regarding a defaced parking sign was also resolved. The extensive recent renovations, including both kitchen and boiler upgrades across both units, suggest proactive maintenance of the building's essential systems, with particular attention paid to modernizing the property while maintaining its historical character.

Risk rating

How 730 20Th 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

Out of 2250 buildings in this neighborhood, 765 are predicted to be safer.
