You Cannot Camp on Your Own Vacant Land in Cochise County

The plan is close to universal among people buying rural acreage: get the land cheap, park a travel trailer on it, live there while you build, and let the house happen at whatever pace the budget allows.

The first half of that plan is not permitted in unincorporated Cochise County, and the county's own wording is not ambiguous about it.

That last sentence closes the door people usually try next. It is not a question of a weekend versus a season, or a tent versus a trailer. Without an established use on the parcel, camping is not a permitted activity.

What is actually allowed

Two routes exist, and both require a permit rather than merely good intentions:

Situation	What the county allows
There is already a principal use on the parcel, such as a house	You may be eligible to live in an RV for up to six months in a calendar year, with an approved temporary use permit
A principal use is being constructed	You may live in an RV during construction, with an approved temporary use permit
Nothing on the parcel and nothing being built	Neither camping nor RV occupancy
Renting the RV out	Not permitted. "Recreational vehicles may not be rented out."

The construction route is specifically framed as temporary occupancy of one RV in conjunction with the construction of a permitted principal use, residential or non-residential. One. Not a trailer for you and another for whoever is helping.

The sequence this forces, and why that is not a bad thing

Read together, those rules mean the RV cannot come first. Something has to be under construction before living on site becomes lawful, which means the permit comes before the trailer.

That order is more sensible than it first appears, because it forces the expensive discoveries to happen before you are committed:

1. Legal access, before anything — a parcel you cannot lawfully reach cannot be built on or delivered to. See owning land you cannot legally reach.
2. Zoning check. The county's interactive map will tell you the district; a Zoning Verification Letter gives you it in writing.
3. Septic. A soil and site evaluation, then a design, then a permit — and remember that septic permits expire after two years, so do not pull one three years before you build. Our septic guide covers the process and the composting toilet trap.
4. Water. Well or hauled, decided on numbers rather than hope — hauled water versus drilling.
5. Building permit, then the temporary use permit for the RV.
6. Site work — pad, drive, drainage. Our site prep checklist has the phases.

The people who get into trouble are the ones who do this in reverse: buy, move a trailer on, live there for a year, and then discover the perc test fails, or the access is not legal, or the zoning district will not carry what they intended to build.

Things the RV still needs

An approved temporary use permit is permission to occupy, not a suspension of everything else. In particular:

• Wastewater has to go somewhere legitimate. If you are in the county's Owner-Builder Program you will be required to obtain a septic or alternative waste treatment permit, and an RV holding tank is not a wastewater system.
• Water has to arrive. Hauling to a tank is normal here; sizing it for a trailer plus a build is the part people underestimate.
• Power. A trailer plus tools plus a December week is a real load — see off-grid solar in winter.
• A right-of-way permit may be required if the property is accessed from a county road, and a floodplain use permit if any of it sits in a designated floodplain.

What we could not confirm

• We could not confirm the fee for a temporary use permit, how long review takes, or how long an approval remains valid. The county reviews the application and sends written authorisation approving or denying — ask about duration when you apply, because a build that outlasts the permit is a predictable problem.
• We could not confirm whether a temporary use permit for construction can be renewed or extended, or what happens if the build stalls.
• We could not confirm whether the six-month allowance for an RV alongside an existing house must be continuous or can be split across a calendar year.
• We could not confirm how the county treats a park model, a converted bus, or a tiny house on wheels for these purposes. The county has adopted Appendix Q of the 2018 IRC for tiny homes, which is a building code question rather than an occupancy one, and the two do not obviously line up. Ask before you buy the thing.
• We could not confirm enforcement practice — how the rule is complained about, investigated or acted on. Absence of enforcement is not permission, and it is not a plan.
• Rules change and this is a summary. Development Services is the authority for your parcel.

The short version

You cannot camp on vacant land you own in unincorporated Cochise County — the county's answer is a flat no covering all forms and all durations, because camping requires an established use on the parcel. Living in an RV is allowed in two situations only: alongside an existing principal use such as a house, for up to six months in a calendar year, or while a principal use is under construction. Both need an approved temporary use permit, it is one RV rather than several, and renting it out is not permitted. So the trailer cannot lead — the access, the zoning, the septic and the building permit all come first, and the practical effect is that you find out whether the parcel works before you are living on it.

Sulfur Springs Land Management does the groundwork that has to happen in that window — access, pad, drainage — and doing it in the right order is most of the value.
