How to find the owner of a vacant lot

Updated November 12, 2026

An empty lot has no mailbox and often no street number, which is what makes its owner feel hard to find. It is not. In Connecticut, as in most states, who owns land is a matter of public record, kept twice: once by the town assessor, for taxes, and once by the town clerk, in the land records. Everything below uses those two offices and a few others, all of them free to search or to visit.

1. Pin down which lot it is

Start with the town's GIS viewer, the online parcel map most Connecticut towns publish. Find the lot by its neighbours' addresses or by the street, click it, and note the parcel ID it shows. Towns usually number parcels by map, block and lot; the format varies, but whatever the town uses is the key every other record is filed under.

Getting this step right matters more on a vacant lot than anywhere else. Unbuilt parcels are frequently recorded under the street name alone, under a lot number from an old subdivision, or under the address of the house next door when the same person owns both. Matching on the parcel ID avoids writing to the wrong owner.

2. Read the assessor's record

Search the assessor's online database by parcel ID, or by street name and scan for records with land but no building. The property record card gives:

• the owner of record, as the assessor has it;
• the mailing address tax bills are sent to, which for a vacant lot is very often somewhere else entirely;
• the last recorded sale, with its date, price, and the volume and page of the deed in the land records;
• the lot size, the land use classification and, in most towns, the zone.

The assessor updates owners from recorded deeds, so a very recent sale may not show yet. If the date of the last sale is old and the price is zero or nominal, the lot probably passed by inheritance, gift or a transfer between relatives rather than by a sale on the open market.

3. Confirm it in the land records

Every Connecticut town clerk keeps the land records: deeds, mortgages, liens, easements and releases, indexed by the names of the parties (grantor and grantee). The deed reference on the assessor's card takes you straight to the one that put the current owner on title. Many towns offer their land record index online, often with images of the documents; every town clerk's office lets you search in person.

Reading forward from that deed tells you whether anything has happened since: a later sale, a mortgage, a lien for unpaid taxes or for work done on the property, or a notice of a pending lawsuit. Reading backward tells you how long the family or company has held it, which is often the best clue to whether they might sell.

4. When the owner is not a person

A company or LLC

Search the company's name in the Connecticut Secretary of the State's business records. The listing shows the company's status, its principal office, and its agent for service of process, and often the names of its principals. Write to the principal office and to the mailing address on the assessor's card.

A trust

A deed into a trust usually names the trustee, who is the person able to sell. The trustee's name and address are on the deed or on the assessor's card.

An estate, or an owner who has died

Assessor records sometimes show an owner as "Estate of" someone, or keep a name long after its owner has died. Connecticut probate courts are organised by district; the court for the district where the owner lived holds the estate file, which names the executor or administrator, the person with authority to deal with the property while the estate is settled.

The town

Lots the town has taken for unpaid taxes, or holds as surplus, are recorded in its own name. Ask the town's finance or assessor's office how it disposes of surplus property; many towns sell surplus land by public auction or sealed bid rather than by private negotiation.

5. Check the taxes

The town tax collector can tell you whether the lot's taxes are paid, and many towns publish delinquent lists. Unpaid taxes on a lot the owner never visits are a common sign of land the owner no longer wants, and a lien for them will be in the land records.

6. Make contact

A short, specific letter to the mailing address of record works better than anything else: name the lot by its street and parcel ID, say who you are, and say plainly that you would like to talk about buying it. The owner of a vacant lot may live elsewhere, may have inherited it, or may simply never have been asked. Do not go onto the lot without permission; it is private property even when nothing is built on it.

Before you write, it is worth knowing what the lot can hold. A vacant lot in a district that allows several units is worth more to you, and possibly to its owner, than one that allows a single house. See how to check the zoning of a property.

Finding vacant lots worth asking about

Looking up one owner is straightforward. Finding which vacant lots are worth the letter is the harder part, and it is what this site does: it reads every parcel's zoning and land use from public assessor records and keeps the ones whose district permits multi-family housing while they hold a single house or nothing at all. In Connecticut that is 51,769 parcels today, 4,199 of them vacant lots. Each record carries the owner of record the assessor filed, the lot size, the zone and the last sale, and the results can be filtered to vacant land.

Common questions

Is property ownership public record in Connecticut?

Yes. Assessor records, including the owner of record and mailing address, are public, and deeds are recorded in the land records kept by each town clerk.

How do I look up a vacant lot with no street number?

Search the assessor database by street name and scan for land-only records, or open the town's GIS map, click the lot, and note its parcel ID. The parcel ID then finds the record directly.

What if the owner is an LLC?

Look the company up in the Connecticut Secretary of the State's business records, which list its principal office and its agent for service. Write to the address the assessor has on file as well.

What if the owner has died?

An owner shown as an estate, or a deed that has not changed since the owner's death, usually means a probate matter. The probate court for the district where the owner lived holds the estate file and the name of the executor or administrator.

General information drawn from public records and how Connecticut towns publish them, not legal advice. A town's zoning office, and an attorney for anything you are buying, are the authorities on a specific property.
