Unlock complete reportThe 11-unit, 1957 Sherman Oaks apartment building at 4337 N Mammoth Ave, currently owned by the Kenneth J Doherty Company Trust, has demonstrated consistent engagement with city services over the past seven years. The property has generated 32 service requests through the MyLA311 system during this period, with the most recent series of six requests in March-April 2026 being information-only inquiries, though the specific nature of the information sought is not disclosed in the records. The building's documented history shows regular oversight by building safety officials, with 16 inspections conducted over the same timeframe, indicating periodic reviews of the property's maintenance and safety standards. However, the building has only undergone two permitted modifications or improvements in the past seven years, which may suggest limited recent renovations or upgrades to the property. While the frequency of service requests and inspections indicates active property management, the relatively low number of building permits and the nature of recent service requests being primarily information-based should be noted as part of the building's recent operational history.

How 4337 N Mammoth 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 1159 buildings in this neighborhood, 127 are predicted to be safer.
