Every house has a past, even if it doesn’t announce itself right away. Maybe you’ve recently moved in and want to know who lived on the property before you. Or, you’re restoring an old house and are wondering what its original character was. You may also be simply curious to find out more about the place where you live.
The history of a house isn’t just about the dates and documents. It’s about discovering how the place evolved, who shaped it, and the time it was built. Some clues are hiding in plain sight, while others take some digging.
Believe it or not, looking up property details isn’t difficult at all these days. All you need is a little bit of patience and dedication.
Check Tax and Assessor Records
Your county tax assessor maintains detailed records on every parcel for tax purposes. These records typically include the current owner’s name, assessed value history going back years or decades, the official year built, square footage, building description (number of stories, construction material, number of bedrooms), and often a property ownership timeline.
In larger counties like Cook County (Illinois), Los Angeles County (California), or Harris County (Texas), you can access this information through the assessor’s website by entering your street address. Many assessor sites also provide an “improvement history” or “permit” link showing when major work was done for example, a 1910 home with a 1978 addition will often show both dates.
Take Advantage of Deeds and Chain of Title
The chain of title is the complete sequence of ownership transfers for your property, documented through deeds filed at the county recorder’s office (also called Register of Deeds or Clerk & Recorder, depending on your state). Each deed shows the seller (grantor), buyer (grantee), date, sale price, and legal description of the property.
Here’s how a typical deed search works: Start with the most recent deed say, recorded in 2023 when you purchased the house. That deed will reference earlier documents, often including the previous owner’s name or the recording information for the prior transfer. You then search for that previous owner as a grantor to find the 2012 deed when they bought it, then trace back to 1994, then 1963, and so on until you reach the earliest available record. Many county recorder offices have online records going back to the 1980s or 1990s. For earlier deeds, you’ll typically need to visit the office in person and search microfilm or bound deed books.
Turn to the Bureau of Land Management General Land Office Records
The U.S. Bureau of Land Management maintains the General Land Office (GLO) database, a searchable online collection of federal land patents dating back to 1788. These records cover the original transfer of public domain land to private citizens through homestead claims, cash sales, military bounty warrants, and railroad grants. You can search by state, patentee name, or legal description.
The GLO database covers most states west of the original thirteen colonies, plus the Northwest Territory states. However, the original thirteen states, Texas (which was never federal land), and Hawaii have separate systems. For these areas, you’ll need to consult state archives or colonial land grant records.
Understanding the relationship between patents and deeds: The patent shows when land first left federal ownership. After that, all subsequent transfers appear in county deed records. If your house sits on land patented in 1873, the patent tells you who first owned it, but you’ll still trace county deeds to follow the chain forward to the present.
Check Out Building Permits
Property records tell you who owned the land, but building permits tell you exactly when the house was built and what was changed over the years. A permit file might reveal that your “1920s bungalow” actually started as a one-story cottage in 1912, gained a second floor in 1928, and had the kitchen remodeled in 1967. These dates and details add precision to your house history that no other source can match.
Building permits became common in most U.S. cities in the early 1900s, though the exact start date varies by location. If you believe your house was built in 1890, don’t be surprised if the earliest permit you find is from 1912 for an addition the original construction may predate the permitting system.
Contact your local Building Department, Planning Department, or Zoning Office. In major cities, online portals now provide permit lookups.
Examine Maps
Maps show what property records cannot: the physical shape of your lot, the footprint of your house, the layout of your neighborhood, and how all of these changed over decades. A deed tells you someone bought property in 1905; a map shows you what stood on that property—and what stood next door. Here are key map resources to explore: Subdivision plats are the original maps filed when a developer divided larger land parcels into city lots. Filed at the county recorder’s office alongside deeds, these maps show lot dimensions, property lines, street layouts, and sometimes even notes about easements or reserved land. If your legal description references “Lot 14, Block 3, Greenwood Addition,” the Greenwood Addition plat map shows exactly where your lot sits.
Historic town and county atlases were published commercially in the late 1800s and early 1900s. These large-format books include detailed maps of cities and townships, often showing individual property owners’ names on their lots. State and university libraries have digitized many of these atlases. Sanborn Fire Insurance Maps are perhaps the most valuable resource for house history research in U.S. cities. Produced from 1867 into the 1970s, these detailed maps were created for insurance underwriters and show building footprints, construction materials, number of stories, porches, outbuildings, and street numbers. The maps use standardized symbols: “D” for dwelling, “Brk” for brick, “1½” for one-and-a-half stories. Modern online aerial imagery provides visual documentation of neighborhood change from the mid-20th century forward. Historic Aerials offers coverage of many U.S. metro areas back to the 1930s–1940s, with side-by-side comparison tools. High-resolution downloads cost a small fee.
Go Through Federal Census Records
U.S. federal census records from 1790 through 1950 are publicly available (a 72-year privacy rule keeps more recent censuses sealed). The 1900, 1910, 1920, 1930, and 1940 censuses include street addresses, making them directly searchable by location.
Census records provide descriptive information beyond names:
- Relationship to head of household (spouse, child, boarder, servant, in-law)
- Age, birthplace, and parents’ birthplaces
- Immigration year and naturalization status
- Occupation and industry
- Whether the home was owned or rented, and if owned, whether mortgaged
- Value of home (in some census years)
- Household members’ literacy, school attendance, and disability status
Find Local History Books and Neighborhood Histories
Published local histories often produced for city centennials, neighborhood anniversaries, or by county historical societies—can provide details about your area’s development that appear nowhere else.
These books rarely index individual houses, but they explain why your neighborhood exists: The arrival of the railroad, the opening of a factory, the extension of a streetcar line, the platting of a new subdivision. This contextual information enriches your house history even when your specific address isn’t mentioned. Check your local library’s history room, the local historical society, and used book sites for local histories. Many have been digitized and appear in Google Books or the Internet Archive.
