Opinion | Lewis: Death by a thousand Band-Aids

As I’ve been doing electrical work in my new home, I’ve had to get up to speed on the latest building codes. One change stood out: the requirement for arc-fault circuit breakers.

Traditional breakers trip when there’s too much current — typically from a short circuit — to prevent overheating and fires. Arc-fault breakers are designed to catch a different, rarer problem: when two conductors get extremely close (think the width of a hair) and create a small electrical arc. In rare cases, that arc can ignite nearby material and start a fire.

These events are rare. Fatalities from them are even rarer.

Arc-fault breakers are expensive. A breaker that cost under $10 now runs $60–$100. They can be finicky — vacuums and other devices trip them regularly — and the requirement has expanded from just bedrooms to nearly the entire house. The result: roughly $2,000 added to the cost of a new home.

The argument for them is simple: If you can save even one life, isn’t it worth it?

I would argue — not always. Before you think I am heartless and only care about saving money, consider three points.

First, scale. The U.S. builds about 1.5 million homes per year. At roughly $2,000 per home, that’s $3 billion annually for this one requirement. At around $300,000 per entry-level home, that same $3 billion could build roughly 10,000 additional homes, housing perhaps 30,000 people.

Second, impact. Electrical fire deaths have declined about 15% over recent decades — roughly 50 fewer deaths per year. Some estimates attribute about half of that improvement to arc-fault breakers. That implies around 25 lives saved annually. Do the math and you get a cost of roughly $120 million per life saved. Whether that’s worth it depends on your perspective — but it raises an important question: Are there ways to spend $120 million and save more than one life?

Third, incentives. If arc-fault breakers meaningfully reduce fire risk, why don’t insurers offer meaningful discounts for homes that have them? Insurance companies are in the business of pricing risk. If the risk is truly lower, premiums should reflect it.

This points to a broader issue: we rarely measure the cost-effectiveness of safety regulations once they are implemented.

If regulators require new safety features, why not also require insurers to reflect verified risk reductions in pricing? That would create a feedback loop — rewarding measures that actually work and discouraging those that don’t.

We all want safer systems. But safety is never free.

We already accept this tradeoff in other areas. Every airline ticket includes fees for security screening. Could we make air travel even safer? Of course. We could double or triple screening intensity. It would save more lives — but at some point, the cost outweighs the benefit.

The same logic applies to housing.

If we add ten regulations like this — each modest on its own — we can easily add $20,000 to the cost of a new home. That may not seem significant on a million-dollar home, but across 1.5 million homes, that’s $30 billion per year.

That’s the equivalent of 100,000 affordable homes that don’t get built. So the real question isn’t whether safety is good. It is. The question is: which safety measures deliver the most benefit for the least cost?

I recently saw a new wildfire detection system will be installed in Edwards/Cordillera. The technology looks really cool, and I hope it works. But I also worry it becomes just another added cost without a measurable benefit. If it truly reduces risk, we should see it reflected in lower insurance premiums. If we don’t, that tells us something important.

The hard truth is that the phrase “if it saves just one life” is powerful — but sometimes not realistic. Resources are finite. Every dollar spent in one place is a dollar not spent somewhere else.

Seatbelts were a breakthrough — low cost, high impact. That’s the gold standard.

But we could save even more lives by lowering highway speed limits to 20 mph. We don’t do that because the cost — to mobility, productivity, and daily life — is too high.

Safety always has a price.

The goal isn’t to eliminate risk entirely. The goal is to reduce risk intelligently — prioritizing the solutions that deliver the greatest benefit per dollar. Otherwise, we don’t just make things safer. We make them unaffordable.
