Unlock complete reportThe property at 12503 N Ralston Ave in Sylmar, a four-unit building constructed in 1952 and currently owned by the Heidi E Alexander Trust, has generated a total of 56 service requests to 311 over the past seven years. The most recent six-month period from October 2025 to March 2026 shows a pattern of waste management and maintenance issues, with five documented incidents involving item pickups and two instances of service not being completed as requested.

How 12503 N Ralston 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.
Out of 310 buildings in this neighborhood, 214 are predicted to be safer.
