How to Get Blueprints of My House: What You Need to Know

Dave Moore - March 21, 2025

Whether you want to renovate the kitchen or add an extension to your home, there’s a good chance you’ll need the blueprints. 

Your home’s blueprints are like a detailed map of your home, so you need them when you want to make changes. If you’re purchasing a new property it’s also a good idea to have the blueprints handy to ensure that everything is secure and as it should be. 

The last thing you want is to discover a hidden passage or attic you know nothing about. Thankfully, you never have to be surprised or scramble to find the blueprints when you use the right tools, and at Information.com we make finding blueprints a breeze. Read on to learn more about how to get blueprints of your house.

What Exactly Are Blueprints?

Before we get into how you can find the blueprints for your home, it’s important to cover what blueprints are. 

Typically, blueprints show how a home or building was originally constructed. In fact, blueprints tend to be made before the house is built to ensure that workers and builders have guidelines. Blueprints are usually drawn up by engineers, architects, and sometimes both.

Original blueprints got the name due to how they were copied. They were copied with a cyanotype process, which created the blue duplicate copy, which is where the term blueprint comes from.

That said, the process for making blueprints today is different. Instead of copying them by hand, computer programs with assistance from computer-aided design tools help architects make blueprints online. Then, they’re printed and distributed to the necessary parties.

It’s for this reason that many architects have copies of their blueprints for each job.

5 Ways to Get Blueprints of Your House 

Several methods will help you get the blueprints for your house. You can use a reverse address lookup tool, like the one we offer through Information.com, or try your luck with another type of online tool. 

Alternatively, you can enlist help from a real estate agent or visit your local county clerk for more information. It’s also possible that the blueprints are printed and stored in your home somewhere, though you may need to reach out to previous owners to find them.

Learn more about each option below.

1. Information.com 

When you need blueprints for your house, one of the best tools you can use is Information.com’s address lookup tool. It’s one of the simplest tools you can use, and all you have to do is enter your state, street address, and city. 

Our address lookup tool will help you find all available public records in relation to the property. This includes everything from blueprints to information about the previous owner or sale of the house. 

With our tool, you can find anything that’s available online about an address as well, so you can find:

• Title and deed information 
• When the property was last sold and who it was last sold to 
• The value of the home 
• Information about the builder of the home and when it was built 
• Contact information for a property 
• Zoning information for a property 
• Current and past residents of a property 

Depending on the property, you may find some or all of this information, and the benefit of working with Information.com is that everything is compiled in one full report. Therefore, you don’t have to leave your home, speak to anyone on the phone, or go to different websites to piece together information. 

Even if we can’t help you find the blueprints, don’t worry; we can point you in the right direction. We can help you discover the right places to visit or the right online databases to search through, so we always recommend starting with Information.com.

2. Reach Out to the Architect Who Built the Home 

When it comes to finding the blueprints, you’ll rarely go wrong when you contact the architect or builder. Since the architect is the one who made the blueprints in the first place, there’s a good chance that they have a copy of the prints for your home. 

Depending on the firm, you can call or email the architect for a copy of the blueprints. In some cases, though, you may have to take a trip out to the office to find the blueprints.

It’s also important to note that sometimes finding the original architect is challenging because it’s not something you’ll find with a quick Google search. Instead, we recommend using our address lookup tool if you’re having trouble finding the original architect. 

Our tool will provide you with information about the original owner of the home, along with who built it, so you can reach out to either party to see if they have the blueprints available. We’ll also help you find any other parties involved with the property, which can also help if you’re not finding anything otherwise.

3. Reach Out to the Previous Owners 

If you’ve recently purchased a home but don’t have a copy of the blueprints, you may need to contact the previous owners. Typically, the owner of a home will have a copy of the blueprints, so there’s a good chance that they’ll be able to give them to you. 

This isn’t a 100% guarantee, but it’s worth it to contact them if you’re having trouble. The best time to contact them for blueprints is during the home sale process. After that, your chances drop because they might make room for new blueprints.

That said, you can still try to source blueprints from the previous owners of a home if you have the right tools. You can use our address lookup tool to find all previous owners of a home, along with their contact information, so getting in touch with them shouldn’t be an issue.

Still, we only recommend going this route once you’ve started to exhaust your other options.

4. Search Local Records

Every county tends to have records of the buildings and homes within it. For this reason, you can contact most local jurisdictions for more information about the blueprints for your home if you know where to look. This information tends to be held by the local building department, but the county clerk’s office or even the tax assessor may have records of the blueprints. 

If you don’t want to go down to these offices in person, you may be able to view records in online databases. 

You can also contact a local real estate agent to see if they can help you. However, if you’re going to work with a realtor, it’s important to have a relationship with them to begin with because most realtors won’t give this information out for free or without incentives.

If you’re unsure about what county you’re located in or where to start looking in public records, you can use our address lookup tool to point you in the right direction. While we can help you find your blueprints, we can also point you to the right places to help you begin your search for a physical copy.

5. Get New Blueprints Made 

If every other method has failed, it’s time to consider getting a new blueprint made. This should only be done as a last resort because you’ll have to pay to have this done, and engineers and architects aren’t cheap. So, only commission new blueprints if you have no way of obtaining records of the previous blueprints. 

To get new blueprints made, you’ll have to have an engineer or architect, or sometimes even both, visit your home. They’ll walk through the home, take measurements, and begin construction of the new blueprints. This process will take time and cost several hundred dollars, but if you have no other way to find the blueprints, it might be your only option. 

It’s also possible to do this yourself with the right software, but we don’t recommend doing so unless you know what you’re doing. Make sure you keep this in mind before having new blueprints made.
