Do I Need a Survey Before Building a Fence in Gladstone, Missouri?

One of the most common questions homeowners ask before installing a new fence is:

“Do I need a property survey?”

The short answer is: No, a survey is not automatically required for every residential fence project in Gladstone—but knowing exactly where your property lines are is your responsibility.

The City of Gladstone requires fences to be installed entirely on your property, and fence posts, footings, and other structural components cannot cross onto neighboring property. The city also allows fences to be built up to the property line, provided they remain entirely within your lot.

Is a Survey Required by the City?

For a typical residential fence, Gladstone’s fence requirements do not specifically require you to submit a land survey with your application. However, depending on your project, the Building Official may request additional documentation to clarify your application.

Even if a survey isn’t required, you are responsible for ensuring the fence is built in the correct location.

When Should You Get a Survey?

A professional property survey is strongly recommended if:

• You’re unsure where your property lines are.
• Your property corners (pins) cannot be found.
• You’re installing the fence directly on or near the property line.
• Your lot has unusual angles or irregular boundaries.
• There has been a disagreement with a neighbor about the property line.
• You’re replacing an old fence that may not have been installed correctly.

The cost of a survey is often much less than the expense of relocating an incorrectly placed fence.

Can I Use Existing Property Pins?

If your property corners are clearly marked and undisturbed, they may be sufficient for planning your fence.

However:

• Don’t rely on old fences.
• Don’t assume landscaping marks the property line.
• Don’t use online GIS maps as exact legal boundaries.

If there’s any doubt, hiring a licensed Missouri land surveyor is the safest option.

What About Easements?

One of the most overlooked parts of fence planning is checking for easements.

Gladstone notes that:

• Fences cannot be installed in stormwater easements or floodplains.
• Fences may be placed in some utility easements, but if the City or utility company needs access later, the property owner is responsible for repairing or replacing the fence after it is removed.

Before installation, review your property records for:

• Utility easements
• Drainage easements
• Public right-of-way areas

Do I Need a Fence Permit?

For most residential fences:

• Fences 6 feet tall or less generally do not require a building permit.
• Fences over 6 feet require a building permit and inspections.

Always verify current requirements with the City before beginning construction, especially if your project includes retaining walls, gates, or unusual fence designs.

Don’t Forget Missouri 811

Before digging post holes, contact Missouri 811 to have underground utilities marked.

This free service helps identify:

• Gas lines
• Electric lines
• Water lines
• Sewer lines
• Communication cables

Locating utilities before excavation helps prevent dangerous accidents and costly repairs.

Tips for a Smooth Fence Installation

Before your fence project begins:

• ✔ Review your property survey if you have one.
• ✔ Locate property pins.
• ✔ Check for easements.
• ✔ Contact Missouri 811.
• ✔ Talk with your neighbor if the fence will be near a shared property line.
• ✔ Hire an experienced fence contractor familiar with Gladstone regulations.

A little planning now can prevent expensive problems later.

Common Mistakes to Avoid

Assuming the Old Fence Was Correct

Many older fences were installed without precise measurements. Replacing an existing fence in the same location doesn’t guarantee it’s on the property line.

Building Over an Easement

Even if allowed, installing a fence in a utility easement can lead to future repair costs if the utility company needs access.

Guessing at the Property Line

A few inches may not seem like much, but encroaching onto a neighbor’s property can result in disputes or having to move the fence.

Final Thoughts

While Gladstone, Missouri does not generally require a property survey before installing a residential fence, it’s one of the smartest investments you can make if your property lines are unclear.

Knowing exactly where your property begins and ends helps you:

• Avoid disputes with neighbors.
• Keep your fence entirely on your property.
• Prevent costly relocation or legal issues.
• Ensure your project complies with city regulations.

If you’re uncertain about your property boundaries, talk with a licensed surveyor before construction. Pair that with a knowledgeable local fence contractor, and you’ll be well on your way to a successful, long-lasting fence installation.
