To find who owns a building, start with the county where the property sits: the assessor’s office, the recorder or clerk’s office, and the county GIS parcel map are all public, and any one of them can give you a name and mailing address in a few minutes if you have the street address. When the name that comes back is a company or a trust, or when the building looks abandoned, the search gets longer but still runs on public records.
Search the County’s Online Property Records First
Most counties publish property data through three tools, and it’s worth knowing what each one is best at.
The county assessor’s website is usually the fastest. You can search by street address, parcel number, or owner name, and results typically show the current owner, the mailing address on file, the assessed value, the lot size, building characteristics, and tax payment status. Some assessor sites also show a history of assessed values, which can hint at when the property last changed hands.
The county recorder or clerk’s website is where the deeds live. A deed names both the seller and the buyer for every recorded transfer, so if you need the full ownership history rather than just the current owner, this is the source. Many recorder sites let you search by name, address, or document type and pull up scanned images of the original paperwork.
GIS parcel maps are the right tool when you can see the building but don’t know its address. These are interactive maps: click the parcel and you get the owner’s name, the parcel number, zoning information, and links back to the assessor or tax records.
Visit the County Offices in Person When Records Are Thin
Smaller and rural counties often haven’t digitized older records, and some records simply aren’t posted online at all. A visit closes that gap.
At the assessor’s office, ask for the property card, a detailed record of a specific parcel that includes ownership, assessed value, and building details. Staff can also walk you through the assessment rolls if you’re struggling to pin the property down. At the recorder’s office, you can inspect deed books directly and request certified copies of recorded documents for a fee, which varies by jurisdiction and generally runs between a few dollars and several dozen dollars per document.
Public libraries in some areas keep local property databases or archived historical records, which helps when the transfer you care about happened decades before anything was scanned.
When an LLC, Corporation, or Trust Is the Owner
This is where a lot of searches stall. The deed comes back listing the owner as something like “437 Main Street Holdings LLC,” and the entity name tells you nothing about the person behind it. Investors, developers, and plenty of individual homeowners use entities to hold real estate.
LLCs and Corporations
Go to the Secretary of State’s website in the state where the entity was formed. Every state runs a business entity database you can search by company name. The filing usually shows when the entity was created, its current status, the registered agent’s name and address, and sometimes the names of officers or managing members. The registered agent is the person or company designated to receive legal documents for the business, and that name is always public.
How much you actually learn varies by state. Some states list LLC members or corporate officers; others only show the registered agent, who may be a commercial service rather than a real owner. When the agent is a service company, you’ve found the middleman, not the person, but the agent’s address is still the legal address for serving documents on the entity.
If the LLC was formed in one state and holds property in another, check both databases. The entity often has a foreign qualification filing in the property’s state that includes additional contact details.
Trusts
Trusts are harder. They generally don’t register with the Secretary of State or any public database, and the trust document itself is private. What is public is the deed: when trust-held property changes hands, the recorded deed typically names the trustee, the person who manages the trust. Identifying the trustee gives you a human being to write to, even if the beneficiaries stay hidden.
Finding the Owner of a Vacant or Abandoned Building
Vacant buildings are their own problem because the owner may have moved, died, or stopped paying attention. The assessor and recorder searches still work, but the mailing address on file is often stale.
Run them anyway. Even an outdated name is a starting point. Then check the county treasurer or tax collector’s website for unpaid taxes on the parcel. A property deep in tax delinquency may be heading toward a lien sale or tax deed auction, and the treasurer’s office sometimes has fresher contact information than the assessor does.
Some cities require owners to register vacant properties and keep a responsible-party contact on file. If the municipality has a vacant property registry, check it. Code enforcement is another route: if the property has been cited for violations, the enforcement file holds whatever contact information the city has been using to reach the owner.
If the recorded owner appears to be deceased, check the local probate court. Probate records name the executor or personal representative of the estate, and that person has legal authority over the property until it’s distributed to heirs.
Hire a Title Company or Skip Tracer When You’re Stuck
When your own research runs out, two kinds of professionals can pick it up.
Title Companies
Title companies research property ownership for a living. They examine tax records and deeds, trace the chain of title backward through every recorded transfer, and confirm who currently holds legal ownership. They also flag liens, judgments, unpaid taxes, and other encumbrances. If you’re thinking about buying the building, you’ll need a title search anyway, and the ownership question gets answered as part of that work.
Skip Tracing
Skip tracing is the process of tracking down someone who’s hard to find through ordinary channels, and real estate investors use it constantly to locate absentee owners of vacant or distressed properties. It combines public records, phone and email databases, forwarding addresses, social media, and sometimes outreach to neighbors or relatives.
You can hire a private investigator or use a skip tracing data service. Data services can charge as little as $0.25 to $1.00 per record; a private investigator costs considerably more. Accuracy in this industry runs around 70 to 80 percent for phone numbers, so expect some dead ends. Skip tracing is legal when done for a legitimate purpose using legal methods; it stops being legal when it involves pulling financial records without authorization, misrepresenting who you are, or using the results to harass.
Legal Limits on Contacting the Owner Once You Find Them
The records are public, but what you do with the information still has rules. Most people looking up a building have a clean reason: they want to buy it, they need to resolve a boundary issue, or they’re dealing with a nuisance. Trouble starts when contact turns aggressive, deceptive, or automated.
Sending a polite letter to the mailing address on file is fine. Phone calls are a different matter if you’re calling in a commercial capacity. The National Do Not Call Registry prohibits sales calls to registered numbers, with fines of up to $50,120 per call for violators.1Federal Trade Commission. National Do Not Call Registry FAQs Telemarketers also cannot call before 8 a.m. or after 9 p.m. in the recipient’s time zone and must identify themselves and their purpose immediately.
The Telephone Consumer Protection Act adds another layer for automated outreach. Using an autodialer or prerecorded voice to call a cell phone without prior consent is illegal, with statutory damages of $500 per violation and up to $1,500 per willful violation.2Office of the Law Revision Counsel. 47 USC 227 – Restrictions on Use of Telephone Equipment That matters for investors and agents running automated campaigns against owner lists built from public records.
One boundary worth naming: property records are public, but financial records are not. The Fair Credit Reporting Act limits who can pull a consumer credit report and for what purpose, and general curiosity about a property owner isn’t on the list.3Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports If a skip tracer offers you bank details or credit history, ask how they got it.
Making First Contact
A written letter to the mailing address on the assessor or deed record is the most reliable opening move. It creates a paper trail, gives the owner time to think, and sidesteps the legal complications of unsolicited phone calls. State your purpose in the first paragraph: you want to buy the property, you have a boundary concern, you’re dealing with a nuisance. Vague letters get ignored.
If the letter bounces or gets no response after a reasonable wait, that’s the point to consider skip tracing or a professional. For anything involving a potential purchase, a legal dispute, or a claim against the property, talk to a real estate attorney before you take the next step. The ownership record is where the conversation starts, not where the decisions get made.
