To find out who owns a building, start with the county assessor’s online records using the building’s street address, then verify legal ownership against the deed on file with the county recorder. Those two offices, together, answer the question for most properties in a few minutes. The complications come when the owner on paper is an LLC, a trust, or someone who has died, and each of those has its own trail to follow.
What to Have Ready Before You Search
The single most useful piece of information is the building’s street address: house or building number, street name, and any unit number. Read it off the building or confirm it through a mapping app. If the lot is large or oddly shaped, the Assessor’s Parcel Number makes searches faster. The parcel number is a unique string the local tax authority assigns to every piece of land in its jurisdiction, and it removes ambiguity when multiple buildings share a street.
You can find the parcel number on a prior tax bill, a recorded deed, or by searching the county assessor’s website. A transposed digit or wrong street suffix will pull up someone else’s property, so getting the address and parcel number right matters more than it sounds.
Start With the County Assessor
Most county assessor websites let you type in an address and pull up the owner’s name, the assessed value, and basic property details within seconds. This is the easiest starting point and the one that answers the question outright for a typical single-family home or small building.
The limitation to understand: the name on the assessor’s roll is whoever the assessor believes should receive the tax bill. It is not necessarily the current legal owner. Properties change hands, and the assessor’s records sometimes lag behind. For a quick answer this is fine. For anything consequential, confirm against the recorder’s records.
Confirm Legal Ownership With the County Recorder
The county recorder, called the register of deeds in some states, files the legal documents that actually transfer ownership: deeds, mortgages, and liens. Recorder offices organize their records through a grantor-grantee index, which lists every property transaction filed with the county, sorted by the names of the parties. The grantor is the person transferring ownership; the grantee is the person receiving it. If you have the current owner’s name from the assessor, you can search for that name as a grantee to find the deed that gave them title.
Many counties offer online portals where you can search by address, parcel number, or party name and pull up scanned copies of recorded documents. The depth of these digital archives varies. Some counties have decades of records online; others only cover documents recorded after a certain cutoff date. If the deed you need predates the digital archive, you may need to visit the recorder’s office in person or request a search by mail.
Fees vary. Self-service copies at a terminal in the office tend to cost around a dollar per page, and certified copies cost more. Many online portals let you view documents for free but charge for downloads or prints. When you open a deed, you’ll see the names of the parties, the legal description of the property, the date of transfer, and often the amount of any transfer tax paid. The most recently recorded deed for a given parcel tells you who currently holds legal title.
While you’re in the recorder’s system you’ll also see mortgages, mechanic’s liens, judgment liens, tax liens, and easements recorded against the property. These don’t change who owns the building, but they tell you who else has a legal claim to it. If the picture starts to look layered, that is usually a sign to bring in a title professional rather than keep digging on your own.
When the Owner Is an LLC or Corporation
County records frequently show a business entity rather than a person as the property owner. An LLC, corporation, or limited partnership holds title, and the deed tells you nothing about the humans behind it. That is by design. Entity ownership shields the individual’s personal assets from liability connected to the property and keeps their name off the public deed.
To identify the people behind the entity, search the Secretary of State’s business database in the state where the entity was formed. Every state maintains one, and basic searches are free in most jurisdictions. These databases show the entity’s filing history, its current status (active, dissolved, suspended), and the name and address of its registered agent. The registered agent is the person or service designated to accept legal documents on the entity’s behalf, and that address is public record. Depending on the state, filings may also list officers, directors, or managing members by name.
Sometimes the registered agent is a professional service company rather than someone connected to the property, and the officers listed may be lawyers or accountants rather than the actual investors. In those cases, the registered agent’s address is still a valid contact point for reaching whoever controls the entity. Cross-referencing the entity’s business address with the property address sometimes reveals whether the owner operates from the building or is an absentee investor.
A Note on the FinCEN Beneficial Ownership Database
The Corporate Transparency Act originally required most U.S. companies to report their beneficial owners to the Financial Crimes Enforcement Network. In March 2025, FinCEN issued an interim final rule removing the reporting requirement for all U.S.-created entities. Domestic LLCs, corporations, and similar entities are now fully exempt from filing beneficial ownership reports.1Financial Crimes Enforcement Network.

The reporting requirement now applies only to foreign entities registered to do business in a U.S. state or tribal jurisdiction, and those foreign entities are not required to report any U.S. persons as beneficial owners. For anyone trying to find out who owns a building held by a domestic LLC, the FinCEN database is not a useful resource. The Secretary of State filings remain the primary public tool for piercing the entity veil without a court order.1Financial Crimes Enforcement Network.

When the Owner Is a Trust
Trusts are another common ownership structure, especially for residential properties held as part of estate planning. When property is transferred into a trust, the deed recorded with the county names the trustee (the person who manages the trust assets) and the name of the trust itself. That deed is public record, so you can find it the same way you’d find any other deed.
The trust document itself is almost never filed with a public office. Trusts are private instruments. Unlike wills, which become public once they enter probate, a trust that functions as intended never passes through the court system. The deed will give you the trustee’s name and the trust’s name, but it won’t reveal the beneficiaries or the terms. If the trust is named something like “The Smith Family Trust dated June 2019,” you at least have a surname. If it’s named “Sunset Holdings Trust,” you may have nothing beyond the trustee listed on the deed.
The trustee is the person legally authorized to manage and transact the property, so for practical purposes like sending a letter or negotiating a purchase, the trustee is your contact. If the trust has been involved in litigation, court records from that case may contain more details about its structure and beneficiaries, but absent a lawsuit, the inner workings of a trust are deliberately kept out of public view.
When the Owner Is Deceased
Sometimes a search reveals an owner who died years ago and no new deed has been recorded. This is more common than you’d expect, particularly with properties that have been in the same family for decades. The records still show the deceased person because no one filed the paperwork to update them.
The first place to check is the local probate court. If the deceased owner’s estate went through probate, the court file will show who was appointed as executor or administrator and how the property was distributed. Probate records are public in most jurisdictions and can be searched by the deceased person’s name. Some courts offer online case search tools; others require a visit or phone call. A probate filing that distributes the property to specific heirs establishes who the new legal owners are, even if no one has yet recorded a new deed with the county recorder.
If no probate case was filed, the property may have passed to heirs automatically under state intestacy laws, but those heirs may not have done anything to formalize their ownership in the land records. In that situation, an affidavit of heirship, a sworn statement identifying the deceased owner’s legal heirs, can be recorded in the county deed records to update the ownership chain. The affidavit doesn’t transfer title on its own; it identifies the heirs so the records reflect who inherited the property. Until something like this is filed, the county records remain stuck on the deceased owner’s name.
When you hit this kind of dead end, searching obituaries for the deceased owner’s name can reveal surviving family members. People-search websites, old phone directories, and historical address records associated with the property can also lead to relatives. A title company experienced in the local area is often the most efficient option, since they deal with these gaps routinely.
Using the County GIS Map
Most counties offer free Geographic Information System portals that display property boundaries overlaid on aerial imagery. You zoom into the neighborhood, click on a lot, and a popup shows the owner’s name, parcel number, assessed value, lot size, and sometimes the year the building was constructed and its square footage. This is often the fastest way to answer the basic question of who owns a building, especially if you’re standing near the property and can visually identify it on the map.
GIS data comes from the same assessor records discussed earlier, so it carries the same limitations. The name shown is whoever the assessor has on file, which may lag behind actual ownership changes. For vacant lots or buildings without visible addresses, the visual interface is particularly useful because you can identify the parcel by its shape and location rather than needing an address.
These tools work in any standard web browser. The quality and depth of the data varies significantly from county to county. Some GIS portals link directly to the recorder’s document archive, letting you jump from the map popup to the actual recorded deed. Others only show assessor data and require you to search the recorder’s system separately.
Checking the Tax-Delinquent List
If you’re researching a property that appears abandoned or neglected, it may be behind on property taxes. County tax collectors typically maintain lists of delinquent properties, and these lists are public. Some jurisdictions publish them online; others require you to visit the tax collector’s office or submit a public records request. The delinquent tax list shows the assessed owner, the amount owed, and how many years the taxes are overdue.
The owner listed on the delinquent rolls is still the legal owner until a tax sale or redemption period changes that. These records provide another angle for identifying who holds title to a building when other searches come up short.
When to Hire a Title Company
When the ownership picture gets complicated, whether because of layered LLCs, deceased owners, missing heirs, or stacked liens, a professional title search is worth the cost. Title companies and abstractors trace the complete chain of ownership back through decades of recorded documents, identify every lien and encumbrance, and produce a report showing exactly who owns the property and what claims exist against it.
A professional title search for a residential property typically costs between $100 and $250, though prices vary by location and complexity. Commercial properties or those with tangled histories cost more. If you’re buying the building, your lender will require a title search and title insurance anyway, so this step is built into the transaction. If you’re just trying to find the owner for a different reason, the fee is still reasonable for the certainty it provides.
Title professionals also catch problems a casual searcher would miss: breaks in the chain of title, improperly executed deeds, and unreleased mortgages from lenders that no longer exist. When accuracy matters more than speed, this is the most reliable path.
