Initial analysis

The 12-unit residential property at 10309 N Mount Gleason Avenue in Sunland, owned by Marcella B Trust Theisman, was constructed in 1987 and has generated a notable number of service requests over the past seven years. The building's service request record shows a total of 48 calls through the MyLA311 system, with 7 of those occurring in early 2026 alone. The most recent cluster of service requests between February and April 2026 predominantly focused on illegal dumping issues, with five separate requests for illegal dumping item pickups and two additional item pickup requests in that period, all of which were promptly closed within days of being reported. A streetlight repair service request from March 2026 is currently in work order status. While the 311 service request activity is relatively high, it's worth noting that there has been only one building safety inspection recorded in the past seven years, indicating limited oversight of the property's structural and safety conditions. The building's age and the concentration of recent service requests may warrant attention, though it's important to note that many of these requests appear to relate more to the surrounding neighborhood than the building itself.

Risk rating

How 10309 N Mt Gleason 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.
