Risk rating

How 9719 N Mason Ave'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.
