Ranked from better to worse for decisions
- Licensed boundary survey
- Recorded plat + monuments
- County parcel GIS (via our directory)
- Phone property-line apps
- Marketing screenshots
Why apps disagree with reality
Phone GPS drifts; parcel layers generalize; fences aren’t always on the line. Two small errors feel huge in the backyard.
Decision cheat sheet
- Curiosity / listing context → county GIS
- Fence, addition, dispute → surveyor
Not a survey. Web parcel maps are tax and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey — especially for fences, setbacks, or disputes.
