Whether your home is 25 or more than 100 years old, clues to its precise age can often be discovered with the right detective work. In order to help you uncover the secret of your home’s age, we talked to a top expert and researched the best alternatives you’ll need to answer that curious question, “How old is my house?”

Ranked among the top 100 real estate agents in the U.S., Edward Kaminsky from Manhattan Beach, California, knows the best methods to find out the age of your home. Along with our extensive research, we have gathered the evidence you’ll need for 11 ways to check your home’s age.

“Age is a major factor because I can tell you even recently built homes, the quality of construction dramatically changes every five to seven years in the current market,” says Kaminsky.

1. Check your ownership documents

Buying a house requires lots of paperwork to be processed due to the legal requirements in your state. In your ownership documents, you usually will have a home inspection report that could show the history of who owned the home previously. If this information is not part of your documentation, an alternative option is to request a copy from the local recorder’s office.

2. Access your county website or assessor’s office

Many city or county websites will have an online parcel search feature. Generally, each property is assigned an assessor’s parcel number (APN). This unique identifier is assigned by the tax assessor to real property under its jurisdiction. The types of information that can be found for each address usually include tax assessments, property value, and when the house was built. Some cities or counties don’t have their information online, which means you’ll need to visit that office in person to find the records via the grantor-grantee index or tract index.

3. Search your home’s address online

Rev up your favorite search engine with choices such as Google, Bing, and Yahoo by typing in your home address. You’ll find that many real estate websites will show the year when your house was built. You can also find other websites that have additional information about property taxes, permitting, deeds, or liens. By doing some cross referencing of the various dates you’ll discover what information is the most accurate.

Pro search tip: When searching for an address, one way to eliminate unrelated results is to place the core address within quotes. This would include placing other words like avenue, street, or road outside the quotation marks. For example, in the Google search bar, you might type, “123 Maple” Road.

4. Hire a building inspector to look at the home construction

When you hire a local building inspector, they could have access to previous building permit applications for your home that would usually indicate the year when it was first built. Also, examining the construction of your home can tell you when it was likely constructed. For example, a home that used knob and tube wiring was popular from 1880 to the 1940s. Flooring and nails have changed with different manufacturing processes over the decades as well. Also, sometimes cornerstones with date stamps can be found in the basement, or newspapers that served as early attic insulation can tell you approximately when a house was built.

5. Visit your community library

If you’re ready to hit the books or even the microfiche, your community library can be a great alternative for discovering old property information when other records can’t be found. Having a discussion with your librarian about the information within the library system and additional community resources could get you faster results.

6. Check your toilet

Ready to literally flush out the real age of your home? It might sound like a strange place to look, but toilets are fixtures that don’t get switched out very often. If the toilet is the original one that was installed when your house was built, you could find a date stamped inside the toilet tank or on the underside of the lid.

7. Reach out to the local historical society

Your local historical society could be a treasure trove of information as its function is to preserve the history of the town. The details for your home could be found within its records or maps to provide the entire chronicle of your home, including the year it was built.

8. Review fire insurance maps

If you can’t find the age of your home through traditional methods, fire insurance maps may be able to help you. These dated maps were originally used by fire insurance underwriters as a way to have a record of all the structures built in a particular area. Detailed maps were often color coded along with a key of the building materials and their level of fire resistance.

9. Research the style of your home’s architecture

Every house has its own unique architecture. If you don’t have access to traditional records, starting with the style of the home could narrow down the era it was likely built. Whether it is neo-traditional, post war, or from the Gilded Age, each architecture is like a unique style that hearkens back to a particular time. Neighboring houses that are similar to your home could also help you determine the age. Along with architectural changes, building codes change over time, as Kaminsky explains about his market.

“For example, it wasn’t that long ago that wood-burning fireplaces were legal, and so they’re not legal to be built anymore. But if you get a home built prior to a specific year in Southern California, it’s possible it has a wood-burning fireplace. So, if that’s something that’s important to you, you know not to buy the newer homes; you have to buy an older home to be able to get a fireplace.”

10. Use a paid service like neighborwho.com

Using a paid service such as neighborwho.com and checkpeople.com can assist you if you can’t find the information elsewhere. Both websites offer a five-day trial for a nominal fee but if you don’t cancel during the trial period, you’ll be charged a higher amount.

Alternatively, an ad-supported resource website that may be helpful is tracemyhouse.com. In addition, FamilySearch.org is a free option that often has access to historical data for properties. Also, census.gov is another website where you can search various records to find older demographic information.

Your tax assessor records will show the year the home was built. To access tax records, it probably can be done online, but most local real estate agents have access to that information. And so you can call a local Realtor® and they should be able to look it up for free.

11. Ask a local real estate agent

According to Kaminsky, having a local agent is one of the best options for getting the property information you need, as they usually have access to the tax assessor documents and a title insurance company.

“Your tax assessor records will show the year the home was built. To access tax records, it probably can be done online, but most local real estate agents have access to that information. And so you can call a local Realtor® and they should be able to look it up for free.”

Why is it important to know when your house was built?

Knowing the age of your house and considering its present condition will tell you how well it has aged and if the previous owners were careful in maintaining it.

“The age certainly affects the value of the home, but it’s usually the current condition because you could have a home built in 1917, but it’s been fully updated; it doesn’t matter if it was built in 1917. If it’s been remodeled and structurally upgraded. So I think how it’s been maintained, and or upgraded, affects the value more so than when the home was actually built,” says Kaminsky.

Other situations when knowing a home’s age is beneficial include:

  • Preparing to sell your home
  • Considering a renovation
  • Getting homeowners insurance
  • Curious about the home’s history
  • Want to accurately determine the value
  • For preventative maintenance measures
  • Using the age as part of a marketing strategy
  • Understanding if there are any hazards

In addition to lead paint, another potential hazard is asbestos, which can sometimes be found in heating ducts, tiles, and ceiling materials.

Does the age of your home impact your home sale?

Satisfying your curiosity isn’t the only reason to pinpoint the age of your property, as often it will help you with insurance, remodeling projects, and even proving historical providence which may increase the value.

Kaminsky describes a time he once sold a property in Virginia for almost $18 million that was designed by former U.S. President Thomas Jefferson.

“That age and that kind of history, it can enhance the salability of the home and, of course, affect the final sale price.”

While age is certainly one of the considerations in a home’s value, other qualities can also help determine the overall value by following the home appraisal model, including:

  • Property features (size, condition, and materials)
  • Improvements to the home (upgrades or additions)
  • Location (proximity to top schools and parks)
  • Market conditions (buyer’s or seller’s market and interest rates)
  • Comparable property values (square footage and amenities)

If you want to get an initial ballpark assessment of your home’s current value, try using HomeLight’s free Home Value Estimator. This tool scans through public records and millions of real estate transactions to give you a real-world home value estimate in less than two minutes.
