To find out who owns a commercial property, start with the county tax assessor’s website and the recorded deed on file with the county recorder. In most cases, an address search on the assessor’s portal gives you the owner’s name in minutes. When the property is held by an LLC, a trust, or a layered corporate structure, you’ll need a few more steps: Secretary of State business filings, fictitious name records, SEC filings for public companies, or a professional title search.
What to Have Before You Start
The full street address is the minimum. Every county property database accepts an address search, and you can always get the address by visiting the building or pulling it up on a map.
More precise is the Assessor’s Parcel Number, sometimes called a parcel ID or folio number. It’s a unique code assigned to every piece of real estate by the local county assessor for tax and record-keeping purposes.1Legal Information Institute. Assessors Parcel Number You’ll find the APN on property tax bills and on the first page of a recorded deed, near the legal description. Using it avoids mix-ups from similar street names and takes you straight to the correct parcel.
Search the County Tax Assessor Website
The county tax assessor’s website is where most ownership searches begin, and it’s often where they end. Nearly every county in the United States runs an online property search portal. Enter the address or APN and you’ll typically see the current owner’s name, their mailing address, the property’s assessed value, and its tax payment status. The mailing address is especially useful, since it tells you where the owner actually receives correspondence, which may differ from the property’s own address.
Some counties limit how much ownership information they display online, particularly in jurisdictions with stronger privacy protections. If the assessor’s site shows parcel details but no owner name, move to the county recorder.
Pull the Recorded Deed at the County Recorder
The county recorder’s office, sometimes called the clerk of court or register of deeds, is the official repository for property documents. Deeds, liens, mortgages, and easements are filed there as public records. When you want definitive proof of ownership, the most recent deed is the document that matters. A deed transfers legal title from the grantor to the grantee, and the grantee named on the most recently recorded deed is the current legal owner.
Many county recorders offer free online search portals where you can look up documents by owner name, APN, or address. Some charge a small fee for access or for document copies, with certified copies generally running a few dollars per page. If the records aren’t online, you can visit the recorder’s office in person and ask staff to pull the recorded deed and any other documents on file for the parcel.
Use a GIS Parcel Viewer
Many counties maintain Geographic Information System mapping tools that let you click a parcel on an interactive map and pull up ownership details. These are helpful when you can see the building but don’t have an exact address, or when a large commercial property spans multiple parcels. The viewer typically shows parcel boundaries, the owner’s name, assessed value, and a link to the full tax record. Search your county’s name plus “GIS” or “parcel viewer” to find the tool.
When the Owner Is an LLC or Corporation
This is where most commercial property searches hit a wall. The deed or tax record frequently names a business entity rather than a person. Something like “345 Industrial Park Holdings LLC” tells you almost nothing about who actually controls the property. Peeling back that layer takes a few extra steps.
Search the Secretary of State Business Registry
Every state requires LLCs and corporations to register with the Secretary of State or an equivalent agency, and those filings are public. Search the entity name on the Secretary of State’s website for the state where the company was formed. The filing will show the formation date, current status (active, dissolved, and so on), and the name and address of the registered agent, meaning the person or company designated to receive legal notices on the entity’s behalf.
The registered agent may or may not be the actual owner. In many cases it’s a commercial registered agent service rather than an individual. The filing sometimes also lists officers, directors, managers, or members, depending on the entity type and the state’s disclosure requirements. Annual reports filed by the entity may hold more current personnel information than the original formation documents, so check those too.
Trace a DBA to the Entity Behind It
Sometimes you know the property by the name on its sign, but that name doesn’t match anything in the property records. The business may be operating under a fictitious name, or DBA (“doing business as”). Most jurisdictions require businesses using a name other than their legal name to file a fictitious business name statement with the county clerk. These filings are searchable and link the trade name to the legal entity or individual behind it. Look on the county clerk’s website for “fictitious business name” or “DBA search.”
The Corporate Transparency Act Won’t Help
You may have heard about the federal Corporate Transparency Act, which originally required most LLCs and corporations to report their beneficial owners to the Financial Crimes Enforcement Network. As of March 2025, FinCEN issued an interim final rule exempting all domestically formed companies from beneficial ownership reporting.2FinCEN.gov. FinCEN Removes Beneficial Ownership Reporting Requirements for US Companies and US Persons Only foreign-formed entities registered to do business in a U.S. state must still file.3FinCEN.gov. Frequently Asked Questions The Treasury Department has also stated it will not enforce penalties against domestic companies or their owners, even retroactively.4U.S. Department of the Treasury. Treasury Department Announces Suspension of Enforcement of Corporate Transparency Act Against US Citizens and Domestic Reporting Companies In practice, there is no federal database you can search to find the real person behind a domestic LLC that owns commercial property.
Properties Held in Trusts
Trusts are another common structure that makes ownership opaque. When a commercial property is held in a land trust, the deed names the trustee rather than the person or entity that actually benefits from the property. Public records show the trustee’s name and little else, because the trust agreement itself is a private document.
A few approaches can help. The trustee’s name and address are on the deed, so you can contact them directly. If the trustee is a bank or trust company, they may confirm only that they hold the property in trust and decline to identify the beneficiary. In that case, look at related records: property tax bills are often mailed to the beneficiary rather than the trustee, and the mailing address on the assessor’s record may point to the real owner. If the property has any active permits, those applications sometimes require the beneficial owner’s name. Beyond that, you may need a professional title search to trace the chain of ownership.
SEC Filings for Publicly Traded Owners
A significant share of commercial real estate is held by publicly traded companies, particularly real estate investment trusts. If you suspect the property belongs to a public company, the SEC’s EDGAR database is a strong resource. Every publicly traded company files an annual report on Form 10-K, which includes a “Properties” section listing the company’s real estate holdings along with addresses, square footage, lease terms, and tenant information.5U.S. Securities and Exchange Commission. Form 10-K Search EDGAR at sec.gov by company name and then search the filing for the property address.
Visit the Property and Ask Around
When the paper trail stalls, a physical visit sometimes yields the simplest answer. Look for “For Sale” or “For Lease” signs, which typically include a broker’s phone number. The broker can tell you who they represent, and even if they won’t name the owner outright, they can pass an inquiry along. Posted building permits may list the property owner or the contractor working on their behalf.
Tenants are another source. The person paying rent knows who they’re paying, or at least knows the name of the management company. Neighboring businesses that have been in the area for years often know the property’s ownership history. It’s old-fashioned, but it fills gaps that databases sometimes can’t.
Hire a Title Company or Abstractor
When you’ve exhausted the free methods or need a thorough, reliable result for a transaction, a professional title search is the answer. Title companies and independent abstractors have access to the full chain of recorded documents for a property, including historical deeds, liens, judgments, easements, and tax records going back decades. They compile everything into a title report that shows the current owner, the complete ownership history, any outstanding claims against the property, and the legal description of the parcel.
For commercial properties, title search fees typically range from a few hundred dollars up to $1,000 or more, depending on complexity and the depth of search required. The cost is higher than for residential searches because commercial parcels often involve multiple prior transactions, layered entity ownership, and more recorded documents. For anyone considering a purchase, a lease negotiation, or legal action involving the property, a title search is the only method that gives you a complete and verified picture.
File a Public Records Request as a Fallback
If a county’s property records aren’t available online and you can’t visit in person, a written public records request is a formal alternative. Property ownership records are public, and government offices are required to provide them. At the federal level, the Freedom of Information Act governs access to federal agency records.6FOIA.gov. Freedom of Information Act How to Make a FOIA Request For county property records, you’ll use the state’s equivalent public records law, which goes by different names in different states. Write to the county assessor or recorder, identify the property by address or APN, and ask for copies of the ownership records. Most offices respond within a few weeks and charge a modest per-page copying fee.
