How to Find and Contact Commercial Property Owners

Commercial property ownership is public record in the United States, so anyone can find out who owns a specific building, warehouse, industrial complex or piece of commercial land. The owner's name and mailing address live in county assessor and property tax records.

Finding the name is the easy part. Finding a phone number or email for the person who actually makes decisions is where most of the time goes, and it is the part that matters if you are a vendor or service provider trying to win commercial real estate work. That is the focus here: how to identify a commercial property owner through public records, and how to reach the right contact once you have the name.

Are Commercial Property Ownership Records Public?

Yes. In the United States, commercial property ownership is public record, filed and maintained by local governments. The openness is for owners' protection: without an open record of a deed or title, imagine the unscrupulous people who would try to make a claim to a property. Deeds and titles are published to establish ownership, and once ownership is established, you can buy, sell, change and borrow against the property.

As Investopedia explains, publicly filing property records creates a "traceable chain of title," which matters when collecting taxes and transferring ownership. More than 100 types of real property documents can be recorded, the most common being deeds, liens, foreclosures, mortgages, easements and plats.

How Do I Find Out Who Owns a Commercial Property?

Start with the county assessor's office, which maintains ownership records for the county and is so named because it assesses property values for tax purposes. In some states the assessor is called the county appraiser. These records are public and free to search. Many county assessors’ searches are online; however, in smaller parts of the country, you may still need to walk into the office and request the records in person. 

Ownership records for commercial buildings are held at the local level, by townships, counties and cities. To search them you'll usually want the property address, and it helps to have the parcel number and nearest intersection on hand.

One practical warning: county search engines are not Google. Many are unforgiving, and you have to enter the address exactly as it is stored in the database or you come up empty-handed. So the first thing to learn is how a given assessor's office formats and handles its data.

How Do I Look Up a Commercial Property Owner for Free?

Searching public ownership records at the county level is free, and for most commercial properties it's straightforward. Here's a real example.

To find out who owns 875 N. Michigan Avenue in downtown Chicago — the skyscraper long known as the John Hancock Center — start at the Cook County Assessor's site (cookcountyassessor.com) and use its address search. Enter the building number (875), the direction (N) and the street name (Michigan). Leave off "Ave" or "Avenue" entirely. Including the road type returns zero results; dropping it returns the record.

That is the single most important habit when searching assessor records: enter the address exactly as the office stores it. These search tools are not like Google, which looks for something close. You have to match the format in their database, and this quirk is not unique to Cook County.

How Do I Find a Commercial Property's Parcel Number and Tax Records?

A parcel number is a unique ID a local government assigns to a piece of property for tax purposes. Some places call it something else. Cook County, Illinois, calls it a property index number (PIN). If you have the parcel number or PIN, you generally don't need the address to pull up a property's ownership and tax records.

To find a parcel number, check a real estate listing for the property or look at the assessor's parcel map. Many assessors' offices publish these maps online, so you can locate the property and read its parcel number and surrounding parcels directly from the map.

And here are the property tax details. In Cook County, it’s called Property Tax Portal.

How Do I Find a Commercial Property Owner's Phone Number and Email?

Public records give you the name of the owning entity, and often a mailing address, but they rarely give you a direct phone number or email for the person who actually makes decisions. Getting those details is a separate job, and it's where most of the work is.

Take the Chicago example. The Cook County records show 875 N. Michigan Avenue is owned by Madison Capital, based in New York City. If you're a vendor or service provider trying to reach the people behind that ownership, your search has only just begun. Next come the hours spent across Google, property tax records, company websites and employee profiles on social media, piecing together names and working out who to contact.

That imbalance is the real problem for anyone selling into commercial real estate. You're going to spend 80% of your time finding the contact information, leaving 20% of your time to build a relationship," said Rob Armstrong, Biscred President. "We believe you should spend 20% of your time finding the right contacts and 80% of the time building relationships."

How Do I Find Commercial Property Owners at Scale?

A CRE database does in seconds what manual record-searching does in hours: it returns the companies that own or operate a given type of property, in a given market, along with the contacts and their details. Instead of working one address at a time through county records, you filter for the owners you want and build a prospect list directly.

In Biscred, you can search by asset class and geography to find the companies behind commercial properties. A search for companies headquartered in Chicago with ownership in office buildings returns 1,445 companies,* each with contact information, in Cook County and across the United States. You can filter to entertainment facilities, government buildings, retail, education, senior living and dozens of other asset classes, then save the records to a list in Biscred or download them to a .csv to upload to your CRM.

Biscred also works at the company level. Searching "Madison Capital" — the owner from the Chicago example — surfaces the firm and gives you contact information for the people working there, so you go from a building to the decision-makers tied to it without stitching together multiple tools.

How Do I Find Decision-Makers for a Commercial Property?

Enter a building address into a CRE database that carries building-level data, and you'll see the companies tied to that property — the owner, the property manager, the contractors and the brokers working on it. That turns a single address into a list of the firms whose decision-makers you'd actually want to reach.

Biscred added building-level data to its prospecting database in early 2026. Continuing with the historic John Hancock Center at 875 N. Michigan Ave. in Chicago, a building search surfaces four additional companies associated with the property: a builder, a property management/CRE brokerage firm, a general contractor and a real estate investment firm.
