Unlock complete reportIs 6439 N Mammoth Ave rent-stabilized?
The Los Angeles Rent Stabilization Ordinance (RSO) caps annual rent increases and requires a legal reason to evict for most rental units first built on or before October 1, 1978. Here's how this building scores on the signals that usually point to coverage.
Based on LA County Assessor records. Coverage also extends to condos, townhomes, duplexes, and units attached to commercial buildings. Not legal advice — confirm with the LA Housing Department.
California Tenant Protection Act of 2019
Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.
AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.
The two-unit residential building at 6439 N Mammoth Ave in Valley Glen, constructed in 1959 and currently owned by Yolanda V Rangel, has maintained a relatively low number of service requests and permits over the past seven years. The most significant recent improvement to the property occurred in October 2022, when seismic safety enhancements were made to the building's foundation, including the installation of sill plate anchor bolts and plywood to cripple walls, demonstrating compliance with Los Angeles' earthquake hazard reduction requirements. The building has experienced regular municipal service interactions, with a cluster of waste-related requests in late 2022, including multiple bulky item pickups and electronic waste disposal, suggesting an active response to household disposal needs during that period. Of particular note, there was one pro-active code enforcement case opened and closed in March 2018, though no details of the case's nature or findings are available in the provided data. The property's service request history shows only one information-only inquiry in March 2025, representing the most recent interaction with municipal services as of October 2023.

How 6439 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 1067 buildings in this neighborhood, 843 are predicted to be safer.
