Unlock complete reportThe property at 6554 N Mammoth Ave in Valley Glen is a single-unit building constructed in 1955, currently owned by Hokkaido Westside Inc. Over the past seven years, the building has experienced several significant modifications and events. Most notably, there has been ongoing work to convert a detached two-story garage/recreation room into an Accessory Dwelling Unit (ADU), with multiple permits issued between 2021 and 2025 for various stages of this project, including a recently issued permit in June 2025 for a small addition (3 ft x 7 ft) related to the ADU conversion. The building's code enforcement history shows three investigations, with the most recent opening in April 2025, though only one violation has been recorded during this period. Service requests through 311 have been relatively minor and primarily consisted of information requests and item pickups, with no indications of persistent or serious issues affecting resident quality of life.
How 6554 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 2215 buildings in this neighborhood, 1706 are predicted to be safer.
