Finding a specific piece of real estate in the sprawl of Southern California can feel like trying to find a single grain of sand at Santa Monica beach. Honestly, it’s a lot. Los Angeles County is home to over 10 million people and roughly 2.3 million separate parcels of land. If you're diving into a los angeles county california property search, you aren't just looking for a house. You're navigating a massive, multi-departmental database that hasn't always been the most "user-friendly" for the average person.
You've probably tried Googling an address and ended up on Zillow or Redfin. Those are fine for pretty pictures. But if you need the actual, legally binding data—the stuff that determines your property taxes or proves who owns what—you have to go to the source. That means dealing with the Assessor’s Office and the Registrar-Recorder.
It's a bit of a maze.
The Assessor Portal: Your First Real Stop
Most people think "property search" and assume they'll see the owner’s name immediately.
Nope.
In California, privacy laws are pretty strict. Government Code Section 6254.21 actually prohibits the county from posting the home addresses of elected or appointed officials online. Since the county can’t easily filter those folks out of the millions of records, they just don’t put any owner names on the public-facing website.

If you use the LA County Assessor Portal, you can find almost everything else, though. You’ll get the Assessor’s Identification Number (AIN), the square footage, the year the place was built, and the assessed value.
How to use the Portal without losing your mind
- Search by Address: Keep it simple. Don't type "Street" or "Avenue." Just the house number and the name.
- Use the Map: If the address isn't popping up (maybe it's a new condo or a weird corner lot), use the Map Search feature. You can zoom in on the actual plot of land and click it.
- The AIN is King: Once you find the 10-digit AIN (formatted like 0000-000-000), write it down. You’ll need it for everything else.
The data here is updated weekly. However, there’s a "blackout" period. Between the time the "Roll" is released in July and the tax extension in September, some info might look a bit stale. That's just the gears of bureaucracy turning.
Finding the Owner: The Part Everyone Gets Wrong
So, you need the name. Maybe you're a neighbor worried about a derelict property, or you're a real estate pro doing due diligence. Since it’s not on the portal, you have two choices.
You can go to an Assessor District Office in person. There are offices in Lancaster, Van Nuys, West Covina, and Culver City, plus the main headquarters at the Kenneth Hahn Hall of Administration downtown (500 West Temple St, Room 320). In person, the public terminals will show you the owner of record.
The other way? Phone it in. You can call (213) 974-3211. It’s a bit old school, but the clerks can give you the owner’s name over the phone for a single property.

What a Los Angeles County California Property Search Won't Tell You Online
There is a big difference between an assessment and a deed.
The Assessor cares about how much the property is worth so they can tax you. The Registrar-Recorder/County Clerk (RR/CC) cares about who actually has the legal title. If you are looking for the actual history of who sold the house to whom, the Assessor Portal is the wrong place to look.
The RR/CC maintains records going back to 1850. But here is the kicker: they do not provide online access to the actual documents or even an index. You have to order them.
Getting the Actual Deeds
- LexisNexis: The county uses LexisNexis as a third-party vendor for online requests. You’ll pay a fee, and it takes about 20 working days to get a certified copy.
- In-Person: You can make an appointment to visit the Norwalk office. This is where the real "detective work" happens. You can look through indexes by name and year to find mortgages, liens, and grant deeds.
- Property Tax Portal: If you just want to know how much tax is owed, go to
propertytax.lacounty.gov. You’ll need that AIN we talked about earlier.
The "Recent Sales" Trap
On the PAIS (Property Assessment Information System) map, you’ll see a feature for "Recent Sales." It’s tempting to treat this as gospel.
Don't.

The county explicitly states that these prices are "unverified." Often, the price shown is just a calculation based on the documentary transfer tax. If a property changed hands as a gift or through a trust, that number might be $0 or wildly inaccurate. Always cross-reference with a title company or a real estate agent if money is on the line.
Weird Nuances of LA Property
If you're looking for a vacant lot, it might not have an address. The Assessor uses something called "Proximity Street Notation." Basically, they name it after the nearest street.
Also, the "City" name on the property record might not be the city you think it is. The Assessor often uses neighborhood names or "clusters." Your house might be in the City of Los Angeles, but the record might say "Van Nuys" or "Hollywood." Don't let that freak you out; as long as the ZIP code and the map location match, you're usually looking at the right spot.
Actionable Steps for Your Search
If you're starting a los angeles county california property search today, here is exactly how to move forward:
- Start at the Assessor Portal: Get the AIN and the basic "Situs" (location) address.
- Check the Tax Status: Take that AIN to the Property Tax Portal to see if there are any delinquent taxes. This is a huge red flag for buyers.
- Verify the Owner: Call (213) 974-3211 if you just need one name. If you need a list, you'll have to pay for "Data Sales" from the county, which usually comes on a DVD or via an FTP transfer.
- Grab the Map: Download the "Assessor Map" PDF from the portal. This shows the actual dimensions of the lot, which is vital for understanding easements or where your fence should actually be.
- Request the Deed: If you need to see if there's a lien or a specific legal description, use the LexisNexis portal linked through
lavote.gov.
Remember that these systems are updated on different cycles. The tax bill you see today might be based on an assessment from six months ago. If there was a recent fire or disaster, the county also has a "Misfortune and Calamity" program that can temporarily lower the assessed value, so look for those markers if you're searching in a recent burn zone.
