Unlock complete reportIs 4259 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 three-unit residential building at 4259 N Mammoth Ave in Sherman Oaks, constructed in 1963 and currently owned by Anita Vogdt Trust, has a complex history that warrants attention. Most notably, there were multiple serious concerns about building security and public safety in 2022, with at least four documented incidents of the property being left abandoned and open to the public, which received priority 2 attention from Building & Safety. These incidents coincided with two Citywide Nuisance Abatement Program cases in 2022, including a general code investigation. The property has generated a significant number of building permits over the past seven years, totaling 31 permits with a cumulative valuation of $339,002. Recent permitted improvements (2024-2025) include substantial work on the roof structure, ADA bathroom upgrades for a beauty salon, tenant improvements for a coffee shop, and repairs to a second-floor dwelling unit. Three closed code enforcement cases from 2022 and an abandoned building complaint from 2022-2024 indicate previous challenges with property maintenance and security. The building has also been the subject of numerous 311 service requests, including traffic sign issues and waste management concerns, though most of these were routine municipal matters rather than building-specific problems. The property's recent permit activity suggests active management and investment in infrastructure improvements, particularly during 2024-2025, though the pattern of abandoned building complaints in 2022 raises questions about past maintenance practices and security protocols.

How 4259 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, 1113 are predicted to be safer.
