Finding accurate floor plans of your house can be a crucial step in planning renovations, selling your home, resolving legal or zoning issues, or simply understanding the structure of your property. If you’ve ever thought, “How do I find the floor plans of my house?” you’re not alone. Fortunately, one of the most reliable ways to do this is by accessing local records and property surveys.
In this guide, we’ll walk you through expert tips on how to Find Floor plans of my house using city archives, government agencies, and professional surveys. Whether you own an old home or a newly constructed property, these methods can help you access or recreate detailed, accurate layouts.
Why Floor Plans Matter
Floor plans are more than visual diagrams. They are functional tools that depict the layout of your home, including wall placements, doors, windows, and sometimes utility connections. Having access to your home’s floor plan helps with:
-
Planning remodeling or extension projects
-
Applying for permits and ensuring code compliance
-
Selling or renting out your home
-
Calculating property taxes and insurance
-
Creating interior design or landscaping plans
-
Understanding load-bearing walls and internal structures
If you don’t already have a copy of your house plans, start by exploring your local government offices and past property surveys.
Start with Your City or County Building Department
One of the most effective places to begin your search is the building or planning department for your city, town, or county. These government offices often store floor plans and construction documents for residential and commercial properties.
Request Permit Records
When homes are built, renovated, or expanded, contractors must submit detailed drawings and floor plans as part of the permit application process. These records are often retained indefinitely and become part of public property records.
Contact your local building department and ask if your property has any building permits on file. Be prepared to provide your address, parcel number, and identification proving that you are the property owner. Many municipalities also offer online databases where you can search for permits and attached documents by address.
Ask for Archived Building Plans
Some city planning departments keep architectural blueprints, especially for homes that were recently constructed or are part of a planned development. Depending on the department’s policy, you may be allowed to view or copy these records.
Keep in mind that access to floor plans might be restricted to the property owner for privacy and security reasons. If the plans aren’t digitized, you may need to visit the office in person or request physical copies for a small fee.
Visit the Local Tax Assessor’s Office
The county assessor’s office is responsible for valuing properties for tax purposes, and they often maintain basic drawings of each structure within their jurisdiction.
These sketches are not detailed blueprints, but they typically show:
-
The shape and size of the structure
-
Number of floors and rooms
-
Square footage
-
Outbuildings and garages
While not architectural-level plans, these records provide a useful foundation when attempting to reconstruct or understand your home’s layout. Many county assessors also have online property search portals where you can download basic property information, including these layout sketches.
Check Public Records and Land Registry
Depending on your country or region, property records and original home plans may be stored in a centralized registry system. In the United States, these documents are often kept at the county level. In the UK and other countries, land registry services may hold this data.
Visit your local public records office or land registry website and search using your property’s legal description or address. Some services may charge a nominal fee to access or download building plans and survey information.
Explore Historic Archives and Libraries
If your home was built many decades ago, local archives or public libraries might be surprisingly helpful. Many older homes are well-documented in historical records, especially in established neighborhoods or designated heritage districts.
Historical societies, city libraries, and municipal archives may have:
-
Original blueprints
-
Builder documentation
-
Plat maps
-
Architectural renderings
-
Real estate brochures
You can either contact these institutions directly or explore online repositories that host digitized records of old buildings and housing developments. Even if they don’t have the exact floor plan, they might offer a similar model used in your neighborhood.
Get a Copy of a Land or Property Survey
A land or property survey provides precise details about the boundaries and structure locations on your lot. While not a substitute for a floor plan, these surveys often include the building footprint and dimensions that can help inform a recreated or measured layout.
Surveys are typically required when buying a home or applying for certain types of loans or permits. If you had a survey done when purchasing your property, check your closing documents or contact your title company or lender.
If you can’t find one, you can commission a new survey. Licensed land surveyors can visit your property, take accurate measurements, and produce updated diagrams that show the current layout of the home and land. You can even request interior measured drawings or floor plans as part of the service.
Request Documents from the Home Builder or Developer
If your home is relatively new or part of a planned housing development, the builder or developer may still have copies of the original floor plans. These companies usually retain copies of their model layouts for customer service, warranty, or legal reasons.
To track down the builder:
-
Review your purchase documents
-
Check your HOA’s records or website
-
Ask neighbors if they have builder contact info
-
Search online using your development name and location
Once you identify the builder, contact them directly and request floor plans for your specific home model. Some developers may require you to prove ownership or pay a small fee for reprints.
Hire a Measured Building Surveyor
If you’ve exhausted all local record options or if your house has been significantly altered over time, your best route may be hiring a measured building surveyor. These professionals specialize in creating highly accurate, scaled floor plans based on laser measurements and digital mapping.
A measured surveyor will:
-
Visit your property in person
-
Use advanced tools like LiDAR, 3D scanners, or laser measurers
-
Document all walls, windows, doors, and built-in features
-
Create detailed architectural floor plans
-
Provide CAD files, PDFs, or paper copies
This service can be especially helpful for homeowners planning renovations, as the resulting plans meet professional and permitting standards.
Measured surveys are often completed quickly—sometimes within a day—and prices vary based on the home’s size and complexity. Although it’s a paid service, it provides the most accurate and usable version of your home’s layout.
Use Digital Tools to Organize and Update
Once you collect the available records, it’s smart to consolidate everything into a digital format. Use simple design software like SketchUp, RoomSketcher, or Floorplanner to create an editable digital version of your layout. These tools allow you to:
-
Visualize your floor plan
-
Add measurements and furniture
-
Print or export the layout for sharing
-
Adjust and update as renovations occur
This is especially useful if you plan to apply for permits or work with contractors who need a clear, printable layout.
Important Considerations and Tips
-
Always bring ID and proof of ownership when visiting city or county offices
-
Be aware of copy and printing fees for official documents
-
If your home is part of a condo or co-op, check with the management company or HOA—they often keep full building plans on file
-
For rural properties or homes outside city limits, visit the county records office rather than city departments
-
Label all files clearly and store copies digitally in the cloud or on a secure hard drive
