Unlock complete reportThe two-unit residential property at 5423 W Thornburn St in Westchester, built in 1952 and currently owned by Bk Anaheim Investments LLC, has had a relatively low volume of service requests over the past seven years, with only eight recorded instances. The most recent service requests, in late 2025, involved street pavement issues and general item pickups, both of which were promptly addressed and closed within a few weeks. Notable among the earlier requests in 2023 were three related to waste management: one for illegal dumping, one for electronic waste, and two separate instances of bulky item removal, all of which were resolved within one to two days of being reported. The building's service request history suggests regular municipal maintenance needs rather than any property-specific issues, with no recorded complaints related to building safety or resident quality of life.

How 5423 W Thornburn St's risk score is calculated
We trained a model on 7 years of LA County code enforcement data — code enforcement cases, building & safety requests, foreclosure registrations, and owner track records. It estimates the probability that LA County will open a code enforcement case at this address in the next 12 months. Lower % = safer.
What the score means for you
Grade A–B — Low risk
LA County rarely opens code cases 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. LA County has opened cases here before and is statistically likely to again.
Out of 801 buildings in this neighborhood, 649 are predicted to be safer.
