Unlock complete reportIs 20020 W Parthenia St 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 property at 20020 W Parthenia St in Winnetka, currently owned by Cornerstone Christian Church, has undergone significant changes in recent years. Built in 1951 and originally consisting of two units, the site is in the midst of substantial demolition and redevelopment activity. In 2023, multiple permit applications were submitted for the demolition of various structures on the property, including the main house with attached garage, a classroom/Sunday school building, a shed, and a pool. While these permits initially received "Corrections Issued" status, subsequent permits from 2025 and 2026 show progress, including the successful demolition of a workshop/hobby room and the backfilling of an existing pool with uncertified fill.

How 20020 W Parthenia St'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
Lower risk — safer than most nearby
LA County rarely opens code cases here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. LA County has opened cases here before and is statistically likely to again.
We don't rank this building against its neighbors. The model's estimates within Winnetka sit too close together for an ordering between them to mean anything.
