A property lines map shows where your property boundaries fall — the legal edges of your parcel. The official versions are traditionally sourced from county parcel records and plat maps, drawn from recorded deeds and surveys. That's different from what you get in Google Maps, which shows roads and satellite imagery but no property boundaries at all.
LotSite's approach sits in between: it shows you high-resolution satellite imagery of your address so you can identify your property lines from the features you can see from above — fences, driveways, hedges, sidewalks — and trace them to measure your lot. It's not a parcel-record overlay; it's a way to see and map your property yourself, instantly and for free. For the full walkthrough of that approach, see our property line map guide.
Official maps follow a few conventions worth knowing. Boundary lines — the legal edges of the parcel — are typically drawn as solid outlines. Setback lines come from local zoning and mark how far structures must sit from the boundary; they matter for sheds, additions, and fences. Easement lines mark utility, drainage, or right-of-way access that crosses your land — you own it, but others have rights to it.
On satellite imagery, the most useful signal is the fence line: fences are clearly visible from above and often align with property boundaries. On a free satellite tool like LotSite you identify these visible features yourself rather than seeing formal line overlays — which is exactly why knowing the conventions helps. For decoding an official document, see our guide on how to read a property survey.

County GIS portals. Many counties publish official parcel boundary overlays on a web map. Free, but the interface — and how current the data is — varies dramatically by county, and finding the right portal can take some digging.
Plat books. The recorded paper maps at your county recorder's office. Definitive, but accessing them takes real effort — a visit or a records request.
Zillow and Redfin. Listing pages show approximate property outlines, but only for homes that are (or were) listed, and the outlines are estimates, not legal boundaries.
A property survey. Hiring a licensed surveyor gives you the legally definitive boundaries, staked on the ground — typically $300–$800. It's the only source that holds up in a dispute.
Since LotSite is satellite-based, the skill that matters is reading the landscape from above. Several features are reliable indicators of where property lines fall:
A few cautions: older fences may sit inside or outside the actual boundary — physical features drift over decades. Some property lines cross straight through visible features. And easements can span your property without being your line at all. Visible features are good indicators, not legal answers — for legal certainty, get a survey. For a step-by-step walkthrough, see find my property lines, and when you're ready to put numbers on what you see, measure your lot.
