Free Site Plan Generator
Enter an address and get a top-down schematic of the property — building footprint, garage, shed, and fence lines — as a downloadable SVG. Free, no signup, powered by OpenStreetMap.
What is a site plan?
A site plan is a top-down schematic of a property showing the building footprint and the other structures and boundaries around it — garages, sheds, fences, and walls. It's the kind of quick visual reference used for early-stage planning, landscaping layouts, and getting oriented on a property before a site visit.
How it works
Geocode the address
Your address is resolved to a location using OpenStreetMap-based geocoding.
Fetch mapped features
Nearby buildings, garages, sheds, and barriers are pulled from OpenStreetMap.
Draw to scale
The features are rendered as a scaled vector SVG you can preview and download.
What's included — and what isn't
Generated plans include the main building footprint, garages and sheds, and fence or wall lines — wherever those features exist in OpenStreetMap. They do not include cadastral lot lines or legal property boundaries, and the result is not a survey or plat. Coverage varies significantly by region; OpenStreetMap mapping is generally strongest in Europe.
Frequently asked questions
Is the site plan generator free?
Yes. It is completely free and unlimited — there is no signup, no account, and no watermark on the download.
How accurate is the generated site plan?
The schematic is drawn from OpenStreetMap community data. Building outlines and feature positions are typically accurate to within a few meters, but accuracy and coverage vary a lot by region — some neighborhoods are mapped in detail, others sparsely.
Can I use this for a building permit or legal survey?
No. This is not a survey, plat, or legal document, and it should never be used as one. It is an informational schematic only. For permits or legal purposes, hire a licensed surveyor.
Why is my fence, garage, or shed missing from the plan?
Features only appear if they have been mapped in OpenStreetMap. If something on your property is missing, that just means it has not been drawn in OSM yet — and since OpenStreetMap is community-maintained, anyone (including you) can add it at openstreetmap.org.
What format is the download?
The site plan downloads as an SVG (scalable vector graphic). It opens in any web browser and in tools like Adobe Illustrator or Inkscape, and it scales to any size without losing quality.
Does my address leave my browser?
The address you enter is sent to our siteplan service, which queries OpenStreetMap-based geocoding and data services to build the schematic. We do not store the address or use it for marketing.
What data source is used?
OpenStreetMap, a free, community-built map of the world, licensed under the Open Database License (ODbL). Every generated plan credits OpenStreetMap contributors.
Where do the property lines come from?
Where available, the lot boundary is drawn from open government cadastral data, shown as a dash-dot line with the lot area labeled. Regional coverage varies, and — like the rest of the plan — it is informational only, never a legal survey.
How do you know where fences are?
Fences and walls already mapped in OpenStreetMap are shown directly. Where none are mapped, the tool also looks for visible fence and hedge lines in aerial imagery along the property boundary and marks anything it finds as approximate.
Site plans are generated from OpenStreetMap data, © OpenStreetMap contributors, available under the Open Database License (ODbL) .
Property lines come from regional open cadastral data sources where available. Aerial imagery used for automatic boundary analysis is provided by Esri, Maxar, Earthstar Geographics, and the GIS User Community.
