Yes, you can be connected to power and water. No, your operation cannot depend on those connections. DSHS told us a mobile food unit may plug into a permanent power source as long as that isn't what it needs to operate — meaning you need a generator, battery, or other alternative on hand.
The practical test is what happens when an inspector shows up: you may be asked to unplug, move, and operate from the new spot without connecting to anything. If your unit can't do that, it isn't mobile in the way DSHS means it.
- 🔌 Connecting is allowed. Being dependent on the connection is not.
- 🔋 Have a generator or battery ready. DSHS said you need an alternative power source so the unit can run unplugged.
- 🚰 Your pump and tanks have to work. Running straight off city pressure isn't enough on inspection day.
- 🚚 They can tell you to move. DSHS described asking operators to relocate across the street and operate from there.
- 🏗️ Permanently fixed is a different path entirely. Wheels off, tanks off, hard plumbed — DSHS told us that unit isn't something they can license as mobile.
Why This Question Keeps Coming Up
A very large number of Texas food trailers don't move. They sit in front of a business, behind a bar, at the edge of a lot — same spot every day, sometimes for years. The owner runs an extension cord, maybe a hose, and that's the operation.
That arrangement made sense under local permitting, where a familiar inspector saw a familiar trailer. Under a single statewide system built around the words "mobile food vendor," it runs into a definition problem — and operators are finding out about it at inspection, which is the worst possible time.
What DSHS Told Us
We asked directly on two separate calls, and the answer was consistent both times.
- You may plug into a permanent power source — as long as it isn't what you need in order to operate.
- You need an alternative power source. A generator, a battery, or some other means of running the unit without shore power.
- Your water system has to function on its own. Your pump needs to work; running directly off city water pressure without the pump isn't the standard.
- You must be able to move at any time. DSHS told us that at inspection, the unit has to be movable — and that any inspection can technically require you to relocate.
- A permanently fixed unit isn't a mobile unit. Wheels removed, tanks removed, hard plumbed and hard wired — DSHS told us they cannot permit that as mobile.
The Scenario DSHS Described
This is the clearest way to understand the standard, and it came directly from the August 12 call.
What This Means If You're Currently Hard Connected
If you've been running off a hose and an outlet without a working pump or a generator, the fix is usually equipment rather than a redesign. A generator you can pull out when needed and a pump that actually functions will typically cover the gap. Several operators we've talked to keep the generator in the tow vehicle and fire it up only when they need it — DSHS raised no objection to that arrangement when we described it.
The harder case is a trailer that's had its tanks removed or been permanently plumbed into a building. That's not a mobile unit under the definition DSHS described to us, and no amount of preparation makes it one.
If You Genuinely Never Move — There's Another Path
This is worth knowing before you spend money trying to force a stationary operation into the mobile framework.
DSHS told us that some jurisdictions will permit a permanently placed unit as a fixed food establishment instead. If you're not moving, the city may license you as a building — which typically means removing the wheels, hard plumbing in, connecting permanent power, and meeting local requirements rather than state mobile requirements.
That's a genuinely different business decision with real tradeoffs in both directions, and we've written it up separately. Should your food trailer become a permanent establishment? →
What We'd Tell an Operator Right Now
If you're parked long-term and plugged in, the question to answer before inspection day is simple: if someone told me to move across the street and keep serving, could I?
If yes, you're in the shape DSHS described and it's worth confirming your specific setup. If no, you have two real options — add the equipment that makes the answer yes, or look seriously at whether a fixed establishment permit through your city fits your business better.
What you don't want is to discover the answer with an inspector standing there, because that costs you a rescheduled inspection and a place back in a queue that's already weeks deep. More on the current backlog →
