How do I find who owns a property — or every owner on a list of parcels?
From one address to a whole county: the manual method, and the faster one

For one property, look up the parcel on the county assessor's or recorder's website: it gives the owner of record and their mailing address, and the deed history shows when it last sold. For a list of parcels, you need owner fields across the whole county, then research behind every LLC to reach a person, which is where a geospatial search engine like MAIA turns days of lookups into one question.
The single lookup takes five minutes. Doing it for 300 parcels across four counties is the week nobody has.
How do I find the owner of one property?
- Find the parcel. Search the address on the county assessor's (or property appraiser's) website. Note the parcel number (APN); every other record keys off it.
- Read the owner of record. The assessor shows the owner's name and the mailing address where tax bills go. When the mailing address differs from the property address, the owner usually doesn't live or operate there.
- Check the deed. The county recorder or clerk holds the deed history: when the property last sold, for how much (in disclosure states), and to whom.
- If the owner is a trust, the trustee is usually named on the deed at the recorder. If it's an LLC, search the state's business registry (usually the Secretary of State), starting with the state where the property is, then the state where the LLC was formed. The filing lists a registered agent, often a commercial service rather than the owner, and in some states a manager or member; Delaware and Wyoming disclose very little.
- Find a way to reach them. Match the person to a phone or email with a contact tool, and check that the name still lines up with the parcel before you call.
Why is it so hard for a whole list?
Because every step above multiplies, and the counties don't cooperate:
- Every county is different. Some publish a parcel download with owner fields; others only offer a one-at-a-time lookup page. A search across 12 counties can mean 12 formats and a few with no download at all.
- Owners hide behind entities. In commercial and industrial property, many owners of record are LLCs. Each one is another lookup.
- Validation eats the time. Every owner has to be confirmed before anyone picks up the phone.
- The list goes stale. A list is someone else's search, already stale.
How do I get a list of property owners for a county?
There are three routes, and they suit different people:
| Route | Good for | The catch |
|---|---|---|
| Download the assessor roll | One county, owner names and mailing addresses | Not every county offers it; no contacts; no context such as zoning or flood |
| Buy a parcel data subscription | Many counties, one schema | You still filter, map and research the owners yourself, in another tool |
| Ask a geospatial search engine | A list filtered by your own criteria, owners researched | You describe the criteria well; it's your thesis, not a pre-built list |
How does MAIA find property owners?
You describe the parcels you're after in plain English, the way you'd brief a colleague: "Industrial parcels over two acres in Fulton County, owned by an individual or a local LLC, that haven't sold in ten years." MAIA finds every parcel that clears the bar, shows them on a map and in a table with the owner of record and mailing address, then researches the owners behind the entities and finds contacts for each row. Every answer shows its sources, so you can check a row before you call.
Then you keep going: narrow by zoning, drop anything in a flood zone, add the parcels next door. MAIA is how you run your own search — and run it again next quarter.
What it looks like in practice: one industrial investor narrowed 3,000 industrial parcels to 300 qualified yards, then 30 worth a call. A VP of Acquisitions at an industrial investor put it this way: "I called an owner off MAIA's contact info and left a voicemail. He called back interested, sent me the lease, and I'm getting an LOI out later this week."
FAQ
Is property ownership public record?
Yes, in the United States the owner of record and the tax mailing address are public through the county assessor or recorder, though some counties keep owner names off their websites and you'll need the recorder or a records request. Contact details such as phone numbers are not part of the record and come from separate sources.
How do I find the real owner behind an LLC?
Search the state business registry, first in the state where the property is, then in the state where the LLC was formed. The filing lists a registered agent and, in some states, a manager or member. Delaware and Wyoming disclose very little.
How do I find off-market property owners?
Start from your own criteria rather than listings: the parcel type, size and location you want, plus owner signals such as long holding periods or out-of-area mailing addresses. Then research the owners of the parcels that fit.
Can I get owners for parcels in several counties at once?
With MAIA, yes: one question can cover several counties, and coverage varies by county and source. By hand, it means a separate lookup or download per county.
Can I legally call or mail the owners I find?
Mailing the owner at the address of record is common practice. For calls and texts, check the Do Not Call registry and the rules that apply in your state before you dial.
