Initial analysis

The two-unit residential building at 582-584 23rd Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1925, currently owned by Mah Sun Sam & Larkin & Lipt. The property has undergone several significant improvements over the years, most notably in 1994-1996 when substantial bathroom renovations were completed to convert split baths into 1.5 baths in each flat. During the same renovation period, additional work was completed including the installation of epoxy bolts and ceiling insulation. The building has also seen window upgrades, with a successful installation of new vinyl windows in 1996 replacing six old windows, and a previous attempt at window improvement in 1987 that expired without completion. A reroofing project was initiated in 1998 but the permit has since expired.

Recent activity at the property has been primarily related to parking enforcement issues, with numerous reports of driveway blocking incidents occurring between November 2023 and January 2024, resulting in several citations being issued. There was also a scooter-related service request in November 2023, a construction noise report in July 2023, and a sidewalk parking violation in February 2023. Earlier incidents include a garbage-related issue that was resolved in April 2022. While these recent incidents primarily involve external factors not directly related to the building's condition or management, they may impact resident convenience and access. The building's maintenance record shows regular updates to essential systems, though the expired permits for reroofing and 1987 window installation suggest some past projects may not have been completed as intended.

Risk rating

How 582-584 23Rd 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.
