How to look up property records and house history by address
A house leaves a paper trail in four public offices: the assessor, the registry of deeds, the building department and the tax collector. Together they tell you when the house was built, how big it is, who sold it to whom, what work was permitted and what it is taxed on. All of it can be looked up by address, most of it online.
Where each record lives
| Record | What it tells you | Where to look |
|---|---|---|
| Assessor record | Year built, living area, lot size, style, rooms, assessed value | Town, city or county assessor website, or the state parcel map |
| Deeds and mortgages | Each sale, the date and the price, easements, liens | County recorder or registry of deeds |
| Building permits | Additions, roofs, furnaces, electrical and plumbing work, with dates | Local building department |
| Tax bills | Annual property tax and any unpaid balance | Town or county treasurer or tax collector |
| Parcel map (GIS) | Lot lines, lot size, zoning, flood zone layers | County or state GIS viewer |
How to look up property records by address
- Find who keeps them. In New England the town or city keeps assessor and permit records; in most other states the county does. Search for your town or county name plus "assessor" or "property search".
- Search the assessor database by street and number. Try the street name alone if the full address does not match; abbreviations differ.
- For deeds, search the recorder or registry by the owner’s name or the address, then open the most recent deed. Each deed cites the one before it.
- For permits, use the building department portal or ask by email for the permit history of the address.
- For a quick summary, a state parcel map shows the assessor facts for every lot on one map.
Where Housemap reads the record for you
Type a US address into Housemap and it reads the public assessor record where the state publishes statewide parcel data, then shows the year built, living area, style, stories, rooms, lot and use:
- Massachusetts: MassGIS Property Tax Parcels, statewide assessor data.
- Connecticut: the statewide CAMA and parcel layer from the Office of Policy and Management.
- New Jersey: statewide parcels with the MOD IV tax list.
- New York: NYS tax parcels for the counties that publish them.
- North Carolina: NC OneMap statewide parcels.
- Florida: statewide parcels with the Department of Revenue tax roll.
- Maryland: Maryland property data from the Department of Assessments and Taxation.
- Utah: statewide parcels with county tax roll data.
- Minnesota: the seven county Twin Cities metro parcels from the Metropolitan Council.
Elsewhere Housemap still builds a plan from the details you enter. It never requests or shows owner names, and it shows each fact as the assessor recorded it, with the source.
How to research the history of a house
For the story of a house rather than its tax facts, follow the deeds backward to the first owner, pull the permit history for every renovation, and look the address up on old fire insurance maps, in the 1950 census and in the local historical commission’s inventory. Our guide on how to find out when your house was built walks through each source.
Old real estate listings, photos at the historical society and a conversation with long time neighbors fill in what the records leave out: the kitchen that was redone, the porch that was enclosed, the year the big tree came down.
What property records do not tell you
- The condition of the roof, the furnace or the water heater. Records list the house, not its equipment. Read the rating labels; see how long appliances last.
- Work done without a permit. A finished basement or an added bathroom may not appear anywhere.
- Exact boundaries. A parcel map is a guide; a survey settles a property line.
- Recent changes. Assessor data is updated once a year in most places, so a new addition can take a year to show.
Keep your own record
The public record is the outline. Your own record, with the install dates, the receipts, the permits and every job done, is what makes the house easy to care for and easy to sell. Housemap starts the file from the public record and keeps the rest in a home maintenance log, with a printable home history you can hand to a buyer.
Questions
How do I look up property records by address?
Search the assessor or property tax website for the town or county where the house is. It lists the year built, size, lot and assessed value. Deeds are at the county recorder or registry of deeds, and permits at the local building department.
Are property records public?
Yes. Assessor records, deeds and building permits are public records in every state, and most are searchable online. Some offices limit online access to certain fields or require a visit or a request for older records.
How can I see the history of my house?
Follow the chain of deeds backward at the registry or recorder, request the permit history from the building department, and check old maps, census records and the local historical commission for the address.
Does Housemap show who owns a house?
No. Housemap reads the assessor record for the house facts only. It never requests or shows owner names.
