To find a landlord’s name, look up the property in your county’s tax assessor database or recorder of deeds records; both are public and will show whoever holds legal title. Property ownership is a matter of public record in every state, so no special credentials are needed. The straightforward case ends there with an individual’s name and a mailing address. The harder cases — a company name, a trust, a deceased owner, or a property with privacy protections — each have their own next step.
Start With the Address and Parcel Number
Write down the full street address, including the building number. Then find the parcel number, which your county may call the Assessor’s Parcel Number (APN), tax map number, or parcel identification number (PIN). You can usually pull it up by entering the address into your county’s online tax assessor portal or GIS map. A current property tax bill, if you have one, also lists the parcel number near the top.
The parcel number matters because many county systems search more reliably by parcel number than by street address. Streets get renamed and buildings get renumbered, but the parcel number stays attached to the land. If you end up requesting records in person or by mail, having both identifiers on hand saves a trip.
Look Up the Owner in County Tax and Deed Records
Most counties run a free online tax assessor portal. Search by address or parcel number, and the system returns a property profile that typically shows the legal owner’s name, their mailing address (which may differ from the property address), the assessed value, and the tax status. The field you want is usually labeled “Owner Information” or “Taxpayer of Record.” That name is who the county considers the current titleholder.
If the mailing address on the profile is different from the rental property itself, that off-site address is often your best way to reach the landlord directly. If the mailing address matches the rental property, the owner may live on-site, or may simply use the rental address for tax mail; in that case, one of the later steps may get you closer.
When the online portal is missing or looks out of date, the county Recorder of Deeds office keeps the authoritative records. You can search the grantor-grantee index — the alphabetical log of property transfers — to pull up the most recent recorded deed. The deed is the legal document that transferred ownership, so if the tax rolls and the deed disagree, the deed wins.
Use the County GIS Map When the Address Is Ambiguous
Many counties publish free Geographic Information System (GIS) maps that show parcel boundaries over aerial imagery. You click a parcel or search by address, owner name, or parcel number, and the map returns the owner’s name, mailing address, parcel boundaries, property characteristics, and assessed value.
GIS maps earn their keep when the address isn’t clear-cut. Corner lots, buildings that span multiple parcels, and properties with inconsistent numbering all become easy once you can just click the parcel. Search for your county name plus “GIS parcel map” or “property map search.” Most mid-sized and large counties offer one.
When the Owner Is an LLC or Corporation
If the county records return a company name — most often an LLC, corporation, or limited partnership — instead of a person, your next stop is your state’s Secretary of State business entity search. Every state runs one, and it’s free. Enter the company name and you’ll typically get the registered agent, officers, managing members, or directors, depending on the entity type.
The registered agent is the person or service authorized to accept legal documents for the company, so that address is reliable for formal correspondence. For LLCs, articles of organization and annual filings may also list managing members by name. States require these filings to be updated on a regular cycle, usually annually or every two years, so the information is generally current. Basic search results are free; certified copies of entity documents typically run $5 to $25.
Don’t expect the federal beneficial ownership database to help. Under an interim final rule published in March 2025, FinCEN exempted all U.S.-created entities — including domestic LLCs — from reporting beneficial ownership information under the Corporate Transparency Act, stating that requiring the reporting from domestic companies “would not serve the public interest.”1FinCEN. Beneficial Ownership Information Reporting Only foreign-formed entities registered to do business in a U.S. state still have to file, and those filings are limited to authorized government users.2Federal Register. Beneficial Ownership Information Reporting Requirement Revision and Deadline Extension For a domestic LLC, the Secretary of State search is your route to a human.
If the owner is a large publicly traded company or real estate investment trust, the SEC’s EDGAR database adds another option. You can search by company name, ticker, or CIK, and annual 10-K filings list the principal office address and executive officers.3SEC. EDGAR Full Text Search This mainly matters for institutional landlords with large portfolios, where no local manager will show up in county records.
When the Owner Is a Trust or an Estate
Property records sometimes list a trust — “Smith Family Trust,” “John Doe Living Trust” — rather than a person. The trustee is the one with authority over the property, and the trustee’s name usually appears on the recorded deed itself, in a form like “Jane Doe, Trustee of the Smith Family Trust.” Pull the deed from the county recorder’s records. If the deed doesn’t name the trustee, some counties record a separate Certification of Trust or Notice of Trust that identifies the trustee and gives a contact address.
When the owner has died and the property is in probate, the court appoints a personal representative (sometimes called the executor or administrator) to handle the estate. Probate case files are generally public, kept at the county courthouse where the probate was filed. Searching the probate index by the deceased owner’s name should surface the case, which identifies the personal representative and their attorney. During probate, the personal representative is the one responsible for the property.
Check City Rental Registries and Code Enforcement
A growing number of cities require landlords to register rental properties with a local housing department or code enforcement office. Rental registries typically capture the owner’s name, a local emergency contact number, and, if the property has a manager, the manager’s name and contact information. Some cities put the registry online in searchable form; others require a public records request.
Registries are useful because they often hold more current day-to-day contact information than county deed records. The deed tells you who holds legal title. The registry tells you who is actually running the property. If the registry isn’t searchable online, submit a written public records request to the city’s records custodian, identifying the property by address and asking for the owner or property manager contact associated with that address’s rental license.
Code enforcement records can help even in cities without a formal registry. When a property is cited for a code violation, the citation lists the owner as the responsible party, along with a mailing address. Many cities and counties let you search code enforcement cases online by address, parcel number, or owner name. If yours doesn’t, the code enforcement office can tell you how to look.
When Records Don’t Give You a Name
Some searches don’t produce a clean answer. A few patterns explain most of them.
- Address Confidentiality Programs. Most states run ACPs that allow domestic violence survivors, stalking victims, law enforcement officers, and certain other at-risk individuals to shield their home address from public records, property records included. A participating owner’s name or address may be redacted or replaced with a substitute address. A small number of states extend similar protection to elected officials and judges.
- Nested LLCs. Some owners stack entities, with one LLC owned by another. Each Secretary of State search then surfaces another company rather than a person. You can keep going one entity at a time; the chain generally ends at a named person or registered agent.
- Outdated tax rolls. Deeds and tax records don’t always update together. A sale may be recorded promptly while the assessor’s records still show the previous owner for months. When the two systems disagree, the most recently recorded deed is the more authoritative source.
- Transfers into a trust or LLC. If the owner moved the property into a trust or LLC after buying it, the tax assessor may still show the individual while the deed now shows the entity. Again, the deed is current.
- Deceased owners. Tax records can keep showing a deceased person’s name for years if no one notifies the assessor. Probate court records, or a recorded affidavit of heirship in the county recorder’s office, will identify whoever currently has authority over the property.
When every public records route runs out, the practical fallback is on the property itself: a management company’s sign, a posted contact number, or a neighbor who knows who handles the building.
