Unlock complete reportIs 21700 W Septo 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 25-unit apartment building at 21700 W Septo St in Chatsworth, built in 1977 and currently owned by Chatsworth 101 LLC, has undergone several significant modifications and improvements over recent years. Most notably, there are ongoing efforts to enhance the property's functionality and increase its unit capacity, including a current initiative to convert the crawlspace into storage space (as of March 2024) and a prior attempt to convert the attached basement/storage area into four ADUs (Accessory Dwelling Units) in late 2023, though this permit was listed as only completing the quality review stage. The building has also undergone important safety improvements, including a significant roof replacement project in March 2021, which complied with the Very High Fire Hazard Severity Zone (VHFHSZ) requirements by using Class A or B materials and met the Cool Roof Product standards mandated for residential roof replacements exceeding 50% of total area. The building's inspection record shows 45 building safety inspections over the past seven years, though no specific violations or safety concerns have been documented in the available permit history. The property has recorded building permits totaling $38,750 in valuation over the past seven years, though the actual impact on resident experience and safety from these improvements varies based on their nature and completion status.

How 21700 W Septo 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
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 92 buildings in this neighborhood, 6 are predicted to be safer.
