Initial analysis

The property at 4624-4626 Irving Street, owned by Cynthia Chiem, is a two-story, three-unit multi-family residential building constructed in 1993 in the Outer Sunset neighborhood. The building has experienced significant regulatory scrutiny, particularly between 2017 and 2018, when multiple building code violations were documented, including issues with illegal units, fire safety violations, rodent infestations, interior surface problems, and the need for various repairs. These violations resulted in several Notices of Violation (NOVs) being issued in January 2018, though records indicate they were eventually abated by May 2018. The building underwent permit applications in 2018 to legalize unauthorized partitions on the second and third floors and to address additional bathroom modifications.

More recently, in October 2020, two complaints were filed regarding electrical work performed without permits and illegal unit modifications, though these complaints are no longer active. The property has experienced recurring maintenance issues, including multiple sewage backup incidents (2021, 2020) and various services requests related to hazardous materials and street cleaning. There was also a documented case of illegal short-term rental activity that was closed and abated. The most recent records indicate tenant buyout activity at the adjacent property (4620 Irving Street) in 2022, though this is for a different unit.

Risk rating

How 4624-4626 Irving St'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 632 buildings in this neighborhood, 442 are predicted to be safer.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
