When Was My House Built? A Los Angeles Homeowner’s Guide to Finding Out
Do you ever wonder, “when was my house built” or “how old is my house?” If you’ve asked yourself these questions, you’re not alone. Many homeowners in Los Angeles – from Echo Park to Pasadena to Inglewood – are curious about what year their house was built. Knowing your home’s construction year (its house age) isn’t just trivia; it can be incredibly useful. In this guide, we’ll show you how to find out when a house was built (often for free!), using Los Angeles-specific resources and tips. We’ll also explain why this information matters and what to do once you’ve uncovered it. Let’s dive in!

Tricia Watts, the owner of MaxNet Homes, often meets homeowners who ask: “how can I find out when my house was built for free?” She emphasizes that understanding your home’s age helps you make informed decisions, especially if you’re considering selling or renovating. In the next sections, we’ll cover how to find out what year your house was built using various methods – many of which are free and easy for Los Angeles residents.
How to Find Out When Your Los Angeles House Was Built (Free Methods)
If you’re wondering “how do I find out what year my house was built?”, you’ll be happy to know there are several resources you can use at no cost. From online databases to old-fashioned sleuthing, here’s how to find out when a house was built in Los Angeles:
- Check Los Angeles County Assessor Records: The LA County Assessor’s Office keeps public records on properties, including the year built. You can use the Los Angeles County Assessor Portal (online property search by address) to find details about your home. Just enter your address or Assessor’s ID Number (AIN) if you have it. The report typically includes the year built along with other info like square footage and lot size. This is a quick way to find out how old your house is by address for free. (Tip: This works for most LA County properties, whether you’re in Los Angeles city or a surrounding community like Pasadena.)
- Use ZIMAS for City of Los Angeles Properties: If your home is within Los Angeles city limits, you have a fantastic tool at your disposal: ZIMAS (Zone Information & Map Access System). ZIMAS is a free online map that provides zoning and property data. Enter your address, and you’ll get a profile of your property. Look for the construction details – ZIMAS will list the original building permit info, including the year your house was built (original construction date). It may even show you permit dates and possibly the names of the architect or builder. This is an excellent way to find out what year a house was built if you live in neighborhoods like Hollywood, Echo Park, or anywhere in LA City. And yes, ZIMAS is completely free to use, so it’s a perfect answer to “how can I find out when my house was built for free?”.
- Search Building Permits and Certificates (LADBS): Another Los Angeles-specific resource is the Los Angeles Department of Building and Safety (LADBS) online records system. LADBS has building permits going back to 1905 and Certificates of Occupancy (which often show when a building was first approved for use) going back to 1940. By searching these records for your address, you can pinpoint when your house was constructed. For example, if you find the original building permit for your home in the LADBS database, it will tell you when that permit was issued (essentially when the house was built). This method can take a bit more effort (and you may need to create a free login or submit a request), but it’s a reliable way to find out the year a house was built and even get copies of original documents. Imagine seeing the handwriting of a 1920s clerk who signed off on your home’s construction!
- Contact Your City’s Building Department (for Other LA County Cities): Not everyone lives in the City of LA. If you’re in a city like Pasadena, Inglewood, Long Beach, or Santa Monica, those cities have their own building departments and records. You can call or visit the city’s building and safety department and ask “how do I find out when my house was built” in their city. Many cities have online permit searches or will help you find the info if you provide an address. For instance, Pasadena has a Permit Center that might have historic permit records for your property. These local offices can help you find out when your house was built or even provide a copy of the original certificate of occupancy. The best part? Simply asking for this info is usually free – it might just take a little time or paperwork.
- Look Up Your Address on Real Estate Websites: If you need a quick answer and aren’t diving into official records yet, try plugging your address into real estate listing sites like Zillow, Redfin, or Realtor.com. When you view the profile of a home (even if it’s not for sale), these sites often list the “Year Built” as part of the property details. This can be a fast way to answer “how old is my house” with just a few clicks. Keep in mind, these sites get their data from public records (like the assessor), so it should be accurate. However, if something looks off, double-check with official sources. Still, as a free way to find out when a house was built, online listings are handy. (For example, you might confirm that your Inglewood bungalow was built in 1948 just by checking Zillow.)
- Scan Your Home Purchase Documents: Think back to when you bought the house (if you did). Often, the appraisal report or the inspection report from the purchase will mention the home’s age or year built. Even the listing sheet from when the home was on the market likely had the year built. If you have a folder of closing documents, skim through to see if the construction year is noted anywhere. This isn’t a public method, but it’s how to find out what year your house was built using paperwork you may already have. And of course, it’s free because you likely have those files on hand.
- Physical Clues and House Features: Sometimes the house itself can tell you its age. While this method isn’t as precise as an official record, it’s worth mentioning. Check your attic, basement, or crawl space for any date stamps or inscriptions. Builders sometimes scribble dates on the framing or backside of drywall. Look at the cornerstone or foundation for a year (some older homes or buildings have the year built engraved on a cornerstone or plaque). Also, consider the architectural style: a mid-century modern style suggests a 1950s-1960s build, while an Art Deco apartment building in Koreatown might scream 1920s or 1930s. Even your neighborhood’s development history can provide a clue. (For example, many tract homes in the San Fernando Valley were built in the post-WWII boom of the 1950s. If you live there, that might answer “how to tell how old your house is” within a decade or so). While these clues aren’t exact, they can help you narrow down the era if official records are hard to find.
- Dig Deeper: Historical Records and Archives: If you have an old house and want its history by address, Los Angeles has great archives to explore. The Los Angeles Public Library has a research guide for house history – they suggest resources like city directories, historic maps, and the County Recorder’s office. For a true history buff, you can trace the history of your house by address by finding previous owners (through grant deeds at the LA County Registrar-Recorder) or looking up old newspaper mentions of your address. This is beyond just finding when the house was built, but it can uncover who built it, lived there, and how the neighborhood evolved. It might be a project, but it’s rewarding if you love history. And as a bonus, if your home turns out to be historically significant (say, it’s a 1912 Craftsman designed by a notable architect), you might even explore having it designated as a historic landmark.
Note: Most of the methods above won’t cost you a dime – they’re how you can find out when your house was built for free. Online databases and public records in Los Angeles are accessible to everyone. It’s essentially like doing a puzzle: piece together the assessor data, city records, and maybe a bit of detective work in archives, and soon you’ll confidently know when your home was built. Whether you’re asking “when was this house built?” about your own home or even a property you inherited or are thinking of buying, these tips will point you in the right direction.
(Fun fact: Even commercial buildings can be looked up using similar methods. So if you’re curious when a building was built in L.A., the same resources apply!)

Common Questions from Los Angeles Homeowners
You might still have some questions, so let’s address a few common ones. Homeowners often phrase the question of house age in different ways. Here are some frequently asked questions and answers:
- How do I find out what year my house was built? – Use any of the free resources mentioned above, like the LA County Assessor’s search or ZIMAS. Simply input your address and look for the “Year Built” field. In most cases, you’ll get an exact year your house was constructed. If those don’t work, check your city’s building department or real estate listing sites for clues.
- How can I find out when my house was built (for free)? – The good news is you usually don’t have to pay for this information. Government records are open to the public. Start with the assessor’s online portal or ZIMAS (for Los Angeles city homes). These will give you solid information at no cost. For a completely free approach, even asking neighbors or long-time residents on your block can sometimes yield insight – someone might remember when the street was developed. In short, there are plenty of ways to find out when your house was built without spending money.
- How do I find out how old my house is by address? – The key here is “by address.” Almost all modern methods revolve around your property address. Enter your address into the tools we discussed (Assessor site, ZIMAS, etc.), and the databases will fetch records tied to that location. If you’re looking for a free address-based house age lookup, that’s essentially what the assessor and city tools provide. Even typing your address into Google with a query like “what year was my home built” or “find out when a house was built [your address]” can surface quick results from real estate sites. Just be sure the source is reliable or cross-verify with official records.
- What if I can’t find any records about my house? – Occasionally, especially for very old properties (say, an old ranch house in a rural part of LA County or a building from the 1800s), you might not find data online. Don’t be discouraged. If online searches fail, you can visit the Los Angeles County Registrar-Recorder’s office. They maintain historical property records (like deeds going back to the 1850s!). While those documents list ownership and transfers rather than explicitly stating “built in 1885,” they can give clues (like the first time the property was sold after a structure was built). Also, check if your area has a local historical society. Sometimes they have archives on old homes, especially if your house is in a historic district or has architectural significance. This is the deeper research route, but it rarely fails to eventually uncover when a house was built.
By now, we’ve covered a variety of angles to answer “when was my house built?”. From quick online tricks to deep-dive research, Los Angeles homeowners have a wealth of information available. Once you discover the age of your house, you might feel a new sense of appreciation for your home’s journey through time.
