A guy out past Nampa called us on a Tuesday wanting his old single-wide gone by Friday. Small trailer, flat lot, nothing complicated about the mobile home demolition itself.

Then he mentioned the power was still on, because he'd been running a shop light out there. And there was a propane tank in the side yard that was probably half full.

That turned a three-day job into a two-and-a-half week job. Not because of the demo. Because of the utilities.

Here's the part that surprises most people: the utility disconnects set your timeline, not the tear-down. The actual mobile home demolition is usually one day of machine work and hauling. Getting Idaho Power out to pull a meter can take longer than everything else combined.

Why utilities have to be dead before mobile home demolition starts

No crew with any sense puts an excavator into a trailer with a live service drop still running to it. Same goes for a gas line. Cut into a charged line with a steel bucket and you've got a very bad afternoon.

Water's less dangerous, just as annoying. Break a pressurized supply line under the home and now you're working a demo site in six inches of mud, in whatever weather Boise decided to hand you that week.

The sewer or septic connection matters for a different reason. Ada County and Canyon County both care about what gets left in the ground when a home comes off a lot. An open lateral is an open hole into somebody's sewer main.

Heads up: "Shut off" and "disconnected" are not the same thing, and that difference costs people days. A breaker flipped off at the panel still has a live drop coming from the pole. What you want is the meter physically pulled by the utility and the service cut at the weatherhead. Ask for exactly that when you call.

Power, gas, and that propane tank in the side yard

Start with Idaho Power. Ask for a permanent service disconnect and meter removal at the address, not a seasonal shutoff.

You'll need to be the account holder, or have the owner on the line with you. There's usually no charge. Plan on three business days to two weeks depending on how buried they are, and spring through late summer they're busiest.

If the home runs on natural gas, Intermountain Gas handles the same thing on their side. They'll pull the meter and cap the riser, free in most cases, and also not instant.

Propane is where people get tripped up. A lot of the trailers around Kuna, Melba and out toward Star run propane, and that tank is either leased or owned.

Leased tank, call whoever fills it. They'll pump the gas back out and haul the tank off, usually at no cost since it's their equipment.

Own the tank? Sell it, give it away, or have it purged and scrapped. What you can't do is leave a fueled tank sitting on the property on demo day. We'll end up working around it, and that's time you're paying for.

Water, sewer, and what to do if there's a septic

On city water, whether that's Boise, Meridian or Nampa, you want the meter pulled or the curb stop closed by the water department. That little shutoff valve under the home doesn't count. It's about to be part of a scrap pile.

On a well, you're usually keeping the well for whatever gets built next. Flag the wellhead with a t-post and some tape so a machine doesn't roll over it.

If you're actually abandoning the well, that's a decommissioning through Idaho Water Resources, and it takes a licensed driller.

Septic is its own small project. Get the tank pumped first, which runs about $350 to $600 around the Treasure Valley, then it either gets crushed and backfilled or pulled out whole. Central District Health has rules on this and they'll want it done right, especially if a new home is going on the lot.

Sewer laterals get capped at the property line. If you're on city sewer in Boise or Meridian, ask before you cap anything, since some inspectors want eyes on it first.

Short version of what needs to be true before we roll in:

✓Electric meter physically removed and the drop cut by Idaho Power

✓Gas meter pulled, or the propane tank pumped and hauled off the property

✓Water off at the curb stop or meter, not just the valve under the home

✓Sewer lateral capped, or septic pumped with the paperwork in hand

✓Anything you're keeping already out of the home

What mobile home demolition costs when utilities hold things up

The disconnects themselves are mostly free or cheap. Septic pumping is the real line item. What actually costs you is calendar time, and sometimes a second trip.

If we show up and the power's still hot, we're not demoing that day. We'll do what we can and come back, but a return trip carries real cost. Yes, we'd love the job either way. We'd still rather spend ten minutes on the phone with you two weeks out and get it right the first time.

So how far ahead should you start calling? Two to three weeks, and the good news is the calls stack.

You can reach Idaho Power, Intermountain Gas, and your water department the same morning and let all three clocks run while you're clearing out the inside. That's also your window to start the permit, since Ada County and most city building departments want disconnect confirmation before they'll issue. We walk through that whole process in our Idaho mobile home demolition permit guide.

While you're waiting on callbacks, it's worth knowing how much of the frame and siding counts as scrap metal, because that does move the number on your quote.

Bottom line

The tear-down is the easy part. Call your utilities two to three weeks out, get real disconnects instead of shutoffs, and deal with the propane early.

Do that and the demo is a one-day event on a lot that's clean by dinner.

Not sure who to call first, or what your particular setup needs? Give us a ring at (208) 593-2877. We've done enough of these around the valley that we can usually tell you in five minutes what's going to slow you down. No pressure either way.
