Does Your Fence Actually Mark Your Property Line? What Portland and Vancouver Homeowners Should Know

Most homeowners assume their property ends wherever the fence is.

And in many cases, that's probably pretty close.

But here's something worth knowing:

A fence isn't necessarily a legal property boundary.

Whether you're buying a home, preparing to sell or planning improvements to your yard, understanding where your property actually begins and ends can prevent some expensive problems.

Your Fence Might Not Be on the Property Line

Fences are often installed based on convenience rather than an official survey.

Sometimes they're deliberately built a few inches or feet inside the property boundary.

Other times, they're installed in the wrong location altogether.

A fence might have been:

• Installed by a previous owner without a survey.

• Built inside the actual property line.

• Placed over a boundary by mistake.

• Constructed around landscaping or natural obstacles.

• Built according to an informal agreement between neighbors.

And just because the fence has been there for decades doesn't automaticaly settle who owns the land underneath it.

Online Property Maps Aren't Surveys

This is probably the biggest misconception.

You can pull up a property on an online map and see what looks like a very precise outline of the lot.

But those lines aren't necessarily accurate enough to establish boundaries on the ground.

Clark County, Washington, specifically warns that its online tax--lot boundaries cannot be used to determine the location of property lines.

The county also states that only a licensed land surveyor can establish the relationship between physical features and actual property boundaries. Clark County GIS

So if you're looking at an aerial image and thinking your neighbor's shed is two feet onto your property, don't assume the map is correct.

How Can You Find Your Actual Property Lines?

There are several places to start.

1. Look for an existing survey.

Previous owners may have had the property surveyed. Check your purchase documents and any records available from previous transactions.

2. Check recorded plats.

Subdivision plats can contain useful information about lot dimensions and boundaries.

3. Research county records.

For Portland properties, Multnomh County provides a Survey and Assessor Image Locator, commonly called SAIL.

It allows you to search for surveys, assessor maps, and other property information. Multnomah County

For Vancouver properties, Clark County offers MapsOnline and property records.

4. Look for survey monuments.

Some properties have existing boundary markers.

But finding what looks like a marker doesn't necessarily mean you've correctly identified the property line.

5. Hire a licensed surveyor.

If you need an accurate boundary determination, this is the appropriate professional to contact.

What About Easements?

Property boundaries and easements are two different things.

An easement may allow another person, utility company, or government agency certain rights to use part of a property.

For example:

• Utility access

• Shared driveways

• Drainage

• Access to neighboring property

• Underground infrastructure

You might own the land but still have restrictions on what you can build or do in that area.

That's why understanding both the property boundaries and any recorded easements is important.

What If Your Neighbor's Fence Is on Your Property?

I wouldn't immediately assume you should tear it down.

Boundary disputes can become complicated, particularly when a fence has existed for a long time.

The first step should be figuring out exactly where the legal boundary is.

If there's a disagreement... a surveyor and potentially a real estate attorney can help determine the appropriate next steps.

Don't assume that moving or removing a fence is automatically within your rights simply because an online map suggests it's on your property.

Why This Matters When Selling Your Home

Imagine you're selling a house and a buyer notices that the fence appears to cross a property line.

Suddenly, something that nobody questioned for 20 years becomes an issue during the transaction.

Depending on the circumstances, it could lead to:

• Additional buyer questions

• Requests for surveys

• Concerns about encroachments

• Delays while records are reviewed

• Negotiations over how an identified problem will be handled

Not every property needs a new survey before selling.

But if there's an obvious boundary question, I'd rather understand it early than have it become a surprise halfway through a transaction.

Portland and Vancouver Have Different Resources

Although Portland and Vancouver share a real estate market geographically, property records and surveying requirements are administered separately.

For Portland-area properties, you can begin with Multnomah County's survey records and SAIL system.

For Vancouver and surrounding areas, Clark County MapsOnline provides parcel information and access to other property research tools.

Neither should be treated as a substitute for a professional boundary survey.

The Bottom Line

Don't automatically assume your fence is your property line.

It might be.

But if you're buying, selling, installing a fence, building an addition or dealing with a neighbor's structure near the boundary, it's worth confirming.

A little research can prevent an expensive misunderstanding.
