You found five acres in Twentynine Palms for a great price.
Your plan seems pretty simple:
Buy the land.
Park your RV on it.
Spend weekends in the desert.
Maybe live there for a while.
Eventually build a house.
It's your land, so you can do that—right?
Not necessarily.
This is one of the questions High Desert land buyers frequently misunderstand.
Owning vacant land in Twentynine Palms, Joshua Tree or another unincorporated area of San Bernardino County doesn't automatically give you the right to use the property as a permanent RV campsite or residence.
There are circumstances where an RV or travel trailer can be temporarily occupied while you're building a home.
But that's very different from:
“I own five acres, so I can live in my RV there indefinitely.”
Let's look at the difference.
Can I Park an RV on Vacant Land?
First, we need to distinguish between several different things:
Parking an RV
Storing an RV
Camping in an RV
Living in an RV
Temporarily occupying an RV while building a permitted residence
Those aren't necessarily treated the same way.
San Bernardino County specifically identifies recreational vehicles and trailers as temporary structures that can require permits.
So before buying land because you intend to use it for an RV, investigate whether your particular intended use is allowed.
Can I Live in an RV on My Vacant Land?
Don't assume you can purchase unimproved acreage, move an RV onto it and establish your residence there indefinitely.
An RV isn't automatically considered a permanent dwelling simply because you own the property underneath it.
This is particularly important for buyers who see inexpensive desert land online and imagine:
“I'll just live in my RV until someday when I decide to build.”
That “someday” is where the problem begins.
San Bernardino County does provide a process allowing temporary RV or travel-trailer occupancy during construction of a residence.
But actual permitted construction needs to be underway as part of that process.
Can I Live in My RV While Building a House?
Potentially, yes.
And this is an important distinction for High Desert land buyers.
San Bernardino County allows a recreational vehicle or travel trailer to potentially be used as temporary residential quarters by someone constructing the first residence on the property.
However, you can't simply say:
“We're planning to build eventually.”
The County states that the applicant must already have a permit issued for construction of the residence before approval of the Temporary Structure Permit.
So think:
Land purchased
↓
House plans/project developed
↓
Building permit for residence issued
↓
Temporary RV/structure approval obtained
↓
RV temporarily occupied during active construction
Not:
Land purchased
↓
RV moved in
↓
Maybe we'll build a house someday
Those are very different situations.
Do I Need a Separate Permit for the RV?
Yes, when you're using it as temporary residential quarters during construction.
The County's process involves a Temporary Structure Permit, and the RV/travel trailer can't simply be placed and occupied before the required approvals are completed. The County says placement can't occur until the temporary-use approval and set down permit have been issued, and occupancy isn't permitted until the setdown passes final inspection.
So even having your house construction permit doesn't mean:
“Okay, pull the RV onto the property tonight.”
There's a process for the temporary residence too.
How Long Can I Keep the RV There While Building?
This isn't intended to become a permanent substitute for completing the house.
The County says the Temporary Use Permit is issued for a period of up to 12 months, with renewal required if the project continues and the temporary use still qualifies. The temporary-use authorization becomes invalid when the related building permit is completed, expires or is canceled. The County also establishes an overall maximum of five years from original issuance.
That last part shouldn't be interpreted as:
“Great! Everybody gets five years of RV living.”
The temporary use remains tied to the qualifying construction project and requires appropriate renewal.
What Happens When the House Is Finished?
The RV stops being your temporary construction residence.
San Bernardino County says recreational vehicles and travel trailers used under this process must be disconnected from utilities before final approval of the construction project.
That's another indication of the intent:
The RV is temporary housing during construction—not the permanent residence.
What If My Building Permit Expires?
That's important.
The temporary RV approval is connected to the construction permit.
The County says the temporary-use permit becomes invalid upon completion, expiration or cancellation of the building permit for which the temporary use was approved.
So you can't pull a building permit, abandon the construction project and continue living in the RV indefinitely.
The house project isn't just paperwork providing an excuse for the RV.
It needs to remain a legitimate permitted construction project.
Can I Buy Land Now, Park My RV There and Build in Five Years?
That's the scenario I'd be particularly careful about.
Buying now and building later can absolutely be a land-purchase strategy.
But don't combine that with the assumption:
“I'll just live in my RV on the property for the five years in between.”
The County's temporary-residential-quarters provision is specifically tied to construction of the residence and requires the residence construction permit before the temporary RV approval.
If your plan is:
Buy in 2026 → build in 2031
then plan on holding the land until you're ready to move into the actual construction phase.
What If I Only Want to Camp There on Weekends?
Don't assume that occasional recreational use automatically makes everything okay either.
How an RV can be used on a particular vacant property is a land-use question worth verifying with the County before buying.
That's particularly important if recreational use is the primary reason you're purchasing the property.
If you tell me:
“I don't want to build anything. I just want five acres where I can leave my trailer and camp whenever I want.”
I'm going to tell you:
Let's verify that use before you buy the five acres.
I'd much rather disappoint you before escrow than after closing.
What About Using the RV as an Airbnb?
No.
San Bernardino County's current Short-Term Rental information says RVs and travel trailers cannot be permitted as short-term rentals.
That's another assumption I'd want a land buyer to eliminate immediately.
Five acres + RV + Airbnb listing isn't automatically a business plan.
What About a Tiny Home on Wheels?
This is where terminology gets messy.
Something marketed as a “tiny home” may actually be constructed on a trailer chassis and treated differently from a permitted residential structure.
Don't assume calling it a tiny house instead of an RV changes the rules.
If your proposed structure has wheels, start investigating how the County classifies it before buying land around that plan.
That's why I've created a separate guide about putting a tiny home on land in San Bernardino County.
Can I Put an RV on Land With No House?
This is exactly where the intended use matters.
The County's general guidance for storing an RV discusses storage on property with a residence, subject to setback requirements.
Vacant land is different because there's no established primary residential use.
And County guidance explains that an accessory use generally exists in conjunction with a legally established primary structure or use. Where the primary use hasn't been established, additional temporary-use requirements may apply.
That's why I wouldn't tell a buyer:
“Sure, it's your property. Park whatever you want there.”
Verify the proposed use.
What About Water While I'm Living in the RV During Construction?
If you're legitimately using an RV as permitted temporary housing during construction, water and sanitation become part of the setup.
The County's temporary-structure process includes final inspection involving electrical hookup and sewer/water connections when the unit has plumbing facilities.
And that brings us right back to something we've been discussing throughout this land series:
Water matters.
A parcel with an existing water meter may look considerably more attractive when you're contemplating an actual construction project.
What About Septic?
Same issue.
Your eventual residence will need an approved wastewater solution.
And temporary living arrangements don't make sanitation requirements disappear.
If you're buying land to build, septic/wastewater should be investigated as part of the overall development plan rather than something you decide after moving an RV onto the dirt.
What About Electricity?
Again, think about the entire construction project.
If conventional electricity is available, determine what's required to establish service.
If your project will be off-grid, investigate the appropriate permitted electrical system.
An RV doesn't magically turn undeveloped land into a fully serviced homesite.
Does This Make Land With Utilities More Valuable for an RV-to-Home Buyer?
Potentially, yes.
Imagine you're comparing two five-acre parcels and ultimately plan to build.
Parcel A
Remote.
No existing water meter.
No obvious conventional electricity nearby.
Difficult access.
Parcel B
Paid water meter.
Electricity close.
Easy access.
Existing building pad.
If your eventual plan involves construction—and potentially permitted temporary RV occupancy during that construction—Parcel B may give you a very different starting point.
That's why we keep coming back to:
Price the project, not just the dirt.
Don't Buy “RV Land.” Buy Land That Fits Your Actual Plan.
This is where online vacant-land advertising can get buyers into trouble.
A listing might say:
Great RV property!
Perfect camping land!
Bring your trailer!
That's marketing language.
It isn't a permit.
If RV use is an important reason you're considering the property, verify your intended use with the appropriate agency before purchasing.
The question isn't:
“Can an RV physically fit on five acres?”
Of course it can.
The question is:
“Can I legally use the RV on this parcel in the way I'm planning?”
That's completely different.
If Your Goal Is Eventually Building a Home
Then tell me that at the beginning.
For example:
“We want to buy five acres in Twentynine Palms, build a home within two years and potentially live in our RV on the property during construction.”
Great.
Now I understand the actual goal.
We can look for land based on things that may matter to the project:
- Residential development potential
- Water
- Power
- Road access
- Terrain
- Building area
- Existing improvements
- Location
- Your construction timeline
Then you'll verify the development and temporary-RV requirements with the County before proceeding.
That's much smarter than buying inexpensive dirt because the listing photograph shows an RV parked on it.
Already Found Vacant Land for Your RV?
Maybe you've found a parcel on Zillow, Realtor.com, Land.com or another real estate website.
Send me the listing or APN and tell me exactly what you're planning.
There's a huge difference between:
“We want to build a house and use our RV temporarily during construction.”
and:
“We want to buy land solely so we can live in our RV.”
Those two buyers may need completely different properties—and potentially very different answers.
Looking for High Desert Land to Build On?
I work with vacant land throughout Joshua Tree, Twentynine Palms and Yucca Valley.
Use my High Desert Land Buyer Form and tell me what you actually want to do with the property.
Tell Me About Your Land Plans
Include:
- Preferred location
- Budget
- Desired acreage
- Whether you plan to build
- Approximate building timeline
- Whether temporary RV use during construction is part of your plan
- Water preferences
- Power preferences
- Road-access requirements
- Any parcel you've already found
You absolutely can buy High Desert land with the goal of eventually building a home.
And in qualifying circumstances, an RV or travel trailer may potentially serve as your temporary home while that permitted construction is actively happening.
But don't confuse that with buying vacant land and establishing a permanent RV residence.
Buy the land for the plan—and verify the plan before you buy the land.
