Sometimes they're close, but other times they're off by a good few feet, which can really matter if you're planning a fence or an addition.
Totally agree—those GIS maps are handy for a rough idea, but I’ve seen them be off by more than “just a bit.” If you’re just curious, they’re fine, but for anything permanent? I’d bite the bullet and get a survey. Learned that lesson the hard way with a driveway years ago... cost me more to fix than the survey would’ve been.

That’s a tough lesson, but honestly, it happens more than folks realize. I always tell people: if you’re doing anything that’ll stick around—like fences, sheds, driveways—step one is a proper survey. Those online maps are just too unreliable for the fine details. Even a few inches off can mean headaches later.

- Ran into this exact issue with a shed a couple years back. Thought I was being clever using the county’s GIS map—turns out, it was off by about a foot.
- Ended up having to move the whole thing after a neighbor flagged it. Not fun, and definitely not cheap.
- Learned my lesson: survey first, build second. Those “close enough” measurements just don’t cut it when property lines are involved.
- Online tools are handy for a ballpark, but I wouldn’t trust them for anything permanent.
Title: Digging into property easements—anyone else find online tools confusing?
That’s spot on—online maps are decent for getting a rough idea, but I’ve seen them be off by more than just a few inches. In one subdivision, the GIS data was outdated and didn’t even show a new utility easement. That led to a lot of back-and-forth with the city and some wasted time. I get why folks want to rely on these tools—they’re convenient—but when it comes to anything permanent, nothing beats a proper survey. It’s not cheap, but it’s way less expensive than having to redo work or deal with legal headaches down the line.
Honestly, I’ve lost count of how many times I’ve stared at those online easement maps and thought, “Is this thing even up to date?” They’re handy for a quick peek, but I wouldn’t trust them for anything serious. Had a project where the online map showed a clear lot, but the surveyor found an old drainage easement smack in the middle—talk about a curveball. It’s tempting to skip the survey to save cash, but man, the headaches later just aren’t worth it.
