Tariffs Are Jacking Up Building Costs—Here’s What Contractors Can Actually Control

I’ll be honest, the first time someone told me that tariffs had added $10,900 to the cost of building a single home, I thought they were being dramatic.

They were not.

If you’ve priced out a job lately and felt like you were losing your mind, you’re not alone. Construction input prices rose at a 12.6% annualized rate in just the first two months of 2026. Copper wire? Up 80% year over year. Iron and steel? Up 58%. Switchgear—the stuff that makes jobsites actually function—up 67%. And that’s before we get into the 25% tariff still sitting on imported kitchen cabinets, the 50% Section 232 tariff on steel and aluminum, and whatever new announcement landed in your news feed this week.

Contractors are getting hit from every angle, and the brutal truth is that most of those hit points are completely outside your control. You can’t negotiate with a trade policy. You can’t shop around for a lower steel tariff. You can write contract clauses that protect you on escalating material prices—and you absolutely should be doing that—but even the best escalation clause doesn’t make the cost disappear. It just decides who absorbs it.

So, let’s talk about the one place where you actually have some leverage.

The Line Item That Keeps Getting Overlooked

When contractors think about cutting costs, lighting usually isn’t the first thing that comes up. It’s not as dramatic as steel or copper. But here’s the thing: it’s also not subject to the same brutal commodity swings, and the price gap between a smart lighting spec and a lazy one can be genuinely significant—especially on bigger commercial or multi-unit jobs.

Let me give you a real example. T8 fluorescent lamps are still installed in a staggering number of commercial spaces and are due for replacement on most projects anyway. The decision of what to replace them with is where the money is. A T8 LED tube replacement can cost anywhere from $3 to $20+ depending on where you’re buying and what brand you’re speccing. That’s not a rounding error. On a 200-lamp warehouse job, that spread is the difference between a comfortable margin and a painful conversation with your client about changing orders.

The same math applies to recessed lighting, high bays, and strip lights. The product category is mature. The technology has standardized. There’s no good reason to be paying a premium for lighting specs when you don’t have to, and in a year where you’re already eating cost increases on copper, concrete, and lumber, the lighting budget is one of the few places you can actually fight back.

What “Controlling Your Lighting Costs” Actually Looks Like

Here’s what I’ve seen work for contractors who are being smart about this right now:
Buy direct, skip the markup. Buying direct from manufacturers or e-commerce platforms like Sunco cuts our unnecessary layers. The same LED tube that costs $12 at a big-box store can be $4–6 when you’re buying in case quantities from a direct-to-contractor source. That is not a small difference.

Stop over-speccing. I see this constantly. A job calls for 3000K color temperature, and someone specs a 3500K “just to be safe,” or ups the lumen count by 40% “because brighter is better.” Brighter is not always better. Sometimes, it’s just more expensive and in the worst cases, a code issue. Spec what the space actually needs.

Consolidate your SKUs. Selectable CCT and wattage-adjustable fixtures exist specifically so you don’t have to stock 15 variations of the same basic product. One fixture that handles 2700K through 5000K and is adjustable from 10W to 14W covers most of your residential and light commercial installs. That’s fewer line items on your PO, fewer returns, and less time spent hunting down the one box of 4000K 12W slims you swear you ordered.

The Part Where I Name Drop a Product

I don’t usually love it when blogs turn into shopping lists, but in the spirit of actually being useful: if you’re replacing T8 fluorescents and you’re not already buying LED tubes in bulk, this is worth a real look. Sunco’s T8 LED tubes—specifically the T8 Hybrid Fluorescent Replacement in 5000K, 50-pack—run around $6 per tube at quantity and are direct-wire compatible, so you’re not adding labor for a driver swap. For a warehouse, retail space, or office where you’ve got runs of T8 fixtures, the economics are hard to argue with.

The Bigger Picture

Most of the cost increases hitting construction right now are real, structural, and not going away any time soon. Trade policy doesn’t resolve itself in a quarter. Material prices that have risen 12%+ in two months don’t quietly drift back down. That means the contractors who come out ahead in 2026 aren’t the ones who wait for things to get easier—they’re the ones who find every efficiency they can in the categories they actually control. Labor is tight, materials are expensive, and clients are already pushing back on bids.

Your lighting spec won’t save your entire margin. But it’s one of the few places on the jobsite where you can make a decision today that immediately puts money back in your pocket. And right now, I’ll take every dollar I can get.
