Can I Fence Vacant Land in the High Desert?

You bought a piece of vacant land in the California High Desert.

Maybe you want to keep people from driving across it.

Maybe you're tired of illegal dumping.

Maybe you plan to keep animals someday.

Maybe you simply want to make it obvious that:

This dirt belongs to somebody.

So can you fence vacant land in the High Desert?

Generally, yes.

But if the property is in unincorporated San Bernardino County, there are rules governing fence height, location, setbacks and visibility.

And before you install several thousand feet of fencing around a large desert parcel, there's an even more basic question:

Are you absolutely sure you know where your property lines are?

Because fencing the wrong five acres would be an unfortunate way to meet your neighbor.

Do I Need a Permit to Build a Fence in San Bernardino County?

It depends on the fence.

San Bernardino County currently lists:

Fences and block walls over 6 feet in height

among construction activities requiring a Building and Safety permit.

That doesn't mean a shorter fence can automatically be placed anywhere you want.

The County Development Code separately regulates fences, hedges and walls, including their maximum height within required setbacks.

This distinction is important:

Permit requirement and zoning compliance are two different questions.

A fence might not require a Building and Safety permit because of its height while still needing to comply with County development standards.

How Tall Can My Fence Be?

For most residential, agricultural and resource-management zoning districts, San Bernardino County's general maximum fence heights within required setbacks are:

Front setback: 4 feet

Street-side setback: 4 feet

Interior-side setback: 6 feet

Rear setback: 6 feet

But there's a particularly relevant exception for High Desert land.

In RL — Rural Living and RC — Resource Conservation zoning districts, the County allows open fences up to 5 feet high within front and street-side setbacks.

That's useful for the kinds of large rural parcels we frequently see around Joshua Tree, Twentynine Palms and Yucca Valley.

But remember:

Those are general County standards.

A specific parcel can be affected by additional requirements, subdivision standards, easements, road rights-of-way or other restrictions.

What Is an “Open Fence”?

Think about the difference between:

chain link or wire fencing

and:

a solid six-foot wall.

An open fence allows visibility through it.

That's particularly important along roads, driveways and intersections where visibility affects safety.

If you're relying on the special RL or RC provision allowing a five-foot open fence within a front or street-side setback, don't assume a five-foot solid privacy fence receives the same treatment.

Open matters.

Can I Build a 6-Foot Fence Around My Entire Property?

Don't automatically assume that.

Six feet may be allowed in interior-side and rear setback areas for many zoning districts.

But front and street-side setback areas generally have lower height limits.

This becomes especially important on:

• Corner parcels
• Parcels with multiple road frontages
• Narrow lots
• Irregular parcels
• Large parcels bordered by several roads

The fact that you're fencing the perimeter doesn't mean every side of the perimeter is treated identically.

One side might be:

front

another:

interior side

another:

rear

and another:

street side.

Different line.

Potentially different rule.

What About a Corner Lot?

Corner parcels deserve extra attention.

San Bernardino County regulates fence height near streets partly because drivers need adequate visibility.

The Development Code contains clear-sight triangle requirements around street intersections.

So the corner where you'd most like to put a substantial fence may be precisely where visibility requirements matter most.

Don't create:

Fort High Desert

and accidentally make it impossible for drivers to see oncoming traffic.

Can I Put the Fence Directly on the Property Line?

Before asking whether you can, I would first ask:

How do you know exactly where the property line is?

This matters enormously with vacant land.

Online parcel boundaries can be useful for understanding approximately where a parcel is located.

But:

Zillow is not a survey.

Google Maps isn't a survey.

An assessor map isn't necessarily a field survey.

A line of old fence posts isn't a survey.

A dirt road isn't necessarily the property line.

And the fact that your uncle walked the property in 1987 and pointed toward a bush isn't particularly compelling boundary evidence either.

If you're installing an expensive permanent fence near a property boundary, consider whether a licensed land surveyor should establish the boundary first.

Do I Need a Survey Before Fencing Vacant Land?

Not every fence project automatically requires a new survey.

But if the exact property boundary is uncertain, a survey can prevent a very expensive mistake.

Imagine fencing five acres.

Posts.

Wire.

Gates.

Labor.

Equipment.

Then your neighbor has the property surveyed and discovers your fence is 12 feet onto their parcel.

Congratulations.

You get to buy the fence twice.

This is particularly important with rural desert parcels where there may be few obvious physical landmarks establishing the property boundaries.

Can I Use GPS on My Phone to Find the Property Line?

Use your phone to help locate the property.

Don't use it to establish a legal boundary for construction.

Consumer GPS, mapping applications and online parcel overlays can be extremely useful when exploring vacant land.

They're not substitutes for professional boundary determination when precision matters.

Your phone can help you figure out:

“We're probably on the parcel.”

That's different from:

“Drill the fence post here.”

What If There's Already an Old Fence?

Don't automatically assume the existing fence establishes the legal boundary.

Old fences can have fascinating histories.

Maybe somebody built it correctly.

Maybe they didn't.

Maybe it followed terrain.

Maybe it was installed for livestock rather than property boundaries.

Maybe neighboring owners agreed to put it somewhere convenient.

Maybe nobody has known exactly why it's there since 1964.

An existing fence is evidence of:

an existing fence.

If the exact legal boundary matters, investigate the actual boundary.

Can I Fence Land That Has a Road or Easement Through It?

Now we need to be careful.

Vacant High Desert land can contain:

• Access easements
• Utility easements
• Road easements
• Drainage easements
• Other recorded rights

Putting up a fence doesn't necessarily eliminate another party's legal right to use an easement.

And installing a locked gate across an access easement may create an entirely different problem.

This is one reason I recommend reviewing the preliminary title report when buying vacant land.

You need to know not only:

What do I own?

but:

Who else may have rights involving this property?

Can I Put a Gate Across a Dirt Road?

Don't do this casually.

First determine:

• Whether the road is entirely on your property
• Whether there's a recorded easement
• Whether neighboring parcels use it for legal access
• Whether utilities have access rights
• Whether emergency access requirements apply
• Whether it's a public or private road
• Whether other recorded rights exist

The fact that a dirt road crosses your parcel doesn't automatically mean you can put up:

PRIVATE PROPERTY — KEEP OUT

and a giant padlock.

That road may be somebody else's only legal access.

And suddenly your quiet desert property has become the neighborhood group-chat topic.

Can I Fence a Landlocked Parcel?

Potentially, but fencing doesn't solve the access problem.

If your property doesn't have legal access, installing a beautiful fence around it does not magically create legal access.

You still need to determine how you are legally entitled to reach your own property.

This is another reason access investigation belongs near the top of a vacant-land due diligence checklist.

Can I Fence Five Acres?

Potentially.

But first, let's talk about how much fence that actually is.

A perfectly square five-acre parcel would have a perimeter of roughly 1,867 feet.

That's more than a third of a mile of fencing.

And real parcels aren't always perfectly square.

So before saying:

“I'll just fence it.”

price:

• Materials
• Posts
• Gates
• Labor
• Equipment
• Survey work if needed
• Terrain challenges
• Future maintenance

This is another example of why I tell land buyers:

Price the project, not just the dirt.

A cheap five-acre parcel can develop some surprisingly expensive hobbies.

What If the Land Is Steep?

Then your fencing project can become considerably more interesting.

High Desert land isn't universally:

flat dirt + bush + dirt + another bush.

Some parcels have:

• Hills
• Washes
• Rock outcroppings
• Significant slope
• Drainage channels
• Difficult vehicle access

The property may legally contain five acres.

That doesn't mean a fencing contractor can casually drive around the perimeter pounding posts into perfectly cooperative soil.

Terrain affects cost.

And the Mojave Desert gets a vote too.

Can I Fence My Land to Stop Illegal Dumping?

Fencing and gates may help discourage unauthorized vehicle access and illegal dumping.

This is one reason absentee landowners sometimes consider fencing High Desert property even before they're ready to develop it.

But think about the actual access points.

If the property has 2,000 feet of perimeter but vehicles primarily enter through one obvious location, a full perimeter fence and a strategically placed access-control solution are very different projects.

Determine what problem you're trying to solve before deciding what to build.

Can I Fence the Property to Keep Off-Road Vehicles Out?

Potentially, subject to applicable fencing requirements.

Again, though, investigate:

• Property boundaries
• Legal roads
• Easements
• Existing access rights
• Fence placement
• Gates
• Visibility
• Terrain

The goal is to keep unauthorized people from crossing your property.

Not accidentally block everybody else from reaching theirs.

Can I Fence Land for Horses?

Potentially, but:

Can I build a fence?

and:

Can I legally keep horses on this parcel?

are separate questions.

Animal keeping depends on zoning, parcel size and applicable County animal-keeping standards.

And then there's the practical question of what fencing is appropriate for the particular animals you're keeping.

We'll tackle the horse question separately.

Because apparently our vacant-land cluster is slowly becoming:

Real Estate + Zoning + Livestock Management.

Welcome to the High Desert.

Can I Fence Land for Chickens or Other Livestock?

Same principle.

First determine whether your zoning and property characteristics allow the animals you want.

Then determine what kind of enclosure is legally and practically appropriate.

And if you're planning chickens:

Remember that San Bernardino County zoning doesn't control the August temperature.

Legal chickens and comfortable chickens are two different due diligence questions.

The Mojave Desert still gets a vote.

Can I Build a Block Wall Around Vacant Land?

Potentially, but a block wall can trigger different structural and permitting considerations than simple open fencing.

San Bernardino County currently requires permits for fences or block walls exceeding six feet in height.

Retaining walls have separate requirements.

And zoning standards still regulate height within setback areas.

If you're planning a substantial masonry wall, investigate the project specifically rather than assuming all “fences” are treated identically.

What About Barbed Wire?

Don't assume every fencing material is allowed everywhere simply because the property is rural.

San Bernardino County's Development Code contains additional fencing standards that can vary by zoning district, use and fence type.

If you're considering:

• Barbed wire
• Electrified fencing
• Razor-type materials
• Specialized livestock fencing
• Security fencing

verify the applicable requirements for your zoning and proposed use before installation.

This is another situation where:

“But my neighbor has it”

isn't particularly useful legal research.

Can I Put a Fence Around Land With Joshua Trees?

Potentially, but construction activity can create another issue:

protected plants.

Fence installation may involve:

• Driving equipment across the property
• Digging post holes
• Clearing vegetation
• Creating access routes
• Disturbing soil

If protected native plants are present, determine whether your fencing project could affect them and whether additional requirements apply before clearing or disturbing vegetation.

A fence may seem like a simple project.

A bulldozer driving the perimeter isn't necessarily simple.

Should I Fence Vacant Land Before I Build?

Maybe.

There can be good reasons:

• Security
• Privacy
• Illegal dumping
• Unauthorized vehicle access
• Animals
• Construction preparation
• Establishing controlled access

But think about your eventual development plan first.

A future project may need:

• Wider construction access
• Different driveway location
• Utility access
• Fire apparatus access
• Grading
• Septic installation
• Well equipment
• Large construction vehicles

Don't install an expensive gate exactly where your future site plan says something else needs to go.

What If I'm Buying Land That's Already Fenced?

Treat the fence as something to investigate—not automatically as proof of the property's boundaries or legal status.

Ask:

• Is the fence actually on the property?
• Does it follow the legal boundary?
• Are there permits if required?
• Does it block an easement?
• Who maintains it?
• Are gates appropriately located?
• Does the fence have value for my intended use?
• Is part of the neighboring parcel accidentally inside it?

A fenced parcel can be attractive.

Just don't assume:

fence = surveyed boundary.

Before You Fence High Desert Land

Start with the APN.

Then determine:

• Exact zoning
• Parcel dimensions
• Property boundaries
• Road rights-of-way
• Easements
• Front, side, street-side and rear areas
• Proposed fence height
• Proposed fencing material
• Gate locations
• Clear-sight requirements
• Terrain
• Protected plants
• Future development plans

Then determine whether your particular fence requires County approval or permits.

That's much cheaper than installing first and investigating later.

Considering High Desert Land?

Tell me what you actually want to do with it.

If you tell me:

“I want five acres.”

I can show you five acres.

But if you tell me:

“I want five acres I can fence, keep two horses on, build a manufactured home, add a workshop and still have room for an RV.”

Now we're looking for the right property.

That's the difference between shopping for acreage and shopping for a project.

Already Looking at a Parcel?

Send me the APN or listing link.

I can help you identify the questions you'll want to investigate before buying.

Because the best time to discover that your fencing, access, animals and future building plans don't work together is:

before you own the dirt.
