Property Lines by Address — Free Lot Boundary
Enter your address and we’ll check public cadastral records. When a usable parcel record is available, we draw its mapped boundary and name the source. Coverage is live in 14 states; otherwise we save your request and say plainly that no map is available from this lookup yet.

We check public parcel records for your address. State coverage does not guarantee a result for every parcel — when no usable record returns, we say so rather than guess.
By continuing you agree to our Privacy Policy. We’ll email you about this; unsubscribe anytime.
A mapped parcel line is not a survey. Do not rely on it to place a fence, wall, or structure.
What this property-lines lookup does
BuildFolio checks public state or county cadastral services for the address you submit. When a service returns usable parcel geometry, this page shows the recorded boundary now and names the source. If the state is unsupported or the service cannot return a usable boundary, we show an unavailable result and save your request for coverage updates. We do not email boundary maps.
What a source-backed result discloses
Source attribution: so you can see which public record supplied the geometry
Coverage state: a clear result or unavailable state for your location
Planning context: the mapped record is descriptive, not a survey
Survey boundary: only a licensed survey can establish a legal line
We do not promise a result for every address. Coverage depends on the public service responding with usable parcel geometry at lookup time, and an unavailable state is better than drawing a shape we cannot support.
Why homeowners look up their property lines
- Fences: building on the neighbor’s side of the line is the classic (expensive) mistake
- Disputes: knowing when to consult a qualified professional can prevent an expensive mistake
- Additions & sheds: setback rules are measured from your property lines
- Buying or selling: know exactly what’s included before you sign
- Trees & driveways: whose tree is it, and is the driveway actually shared?
Important: when you need a licensed survey
County parcel maps are planning references, not legal boundary determinations. For decisions about a boundary, structure, or easement, consult a qualified professional. Only a licensed land survey is authoritative.
Frequently asked questions
Is the property-lines lookup free?
Yes. The lookup is free. In 14 supported states, a covered address may return a mapped parcel boundary now; otherwise we save your request for coverage updates. The result is not a survey.
Where do the property lines come from?
Available results come from public state or county cadastral services. Each mapped result names its source. Coverage and record quality vary by location.
How does the property-lines lookup work?
Enter your address and email. We save the request, check live parcel coverage, and show a mapped record immediately when usable geometry is available. If it is unavailable, we explain that and keep the request for coverage updates. We do not email boundary maps.
Can I get my lot dimensions by address?
In the 14 states we cover, when a county parcel boundary is drawn we also measure it: approximate side lengths, a length × width for a roughly rectangular lot, and the perimeter. They are measured on the county parcel map, so they are approximate and not a survey. A curved or irregular lot gets its perimeter only.
Are county GIS property lines accurate enough to build a fence?
Data quality varies by source and location. If a line affects a fence, structure, easement, or dispute, use a licensed survey before you act.
Can Google Maps show my property lines?
Google Maps may show parcel outlines in some places, but availability and accuracy vary. It is not a legal boundary determination; consult a licensed surveyor where the line matters.
