The Permit Signal: What 100s of Millions of Building Permits Tell Us About the Market

Every month, hundreds of thousands of building permits are filed across the United States. Most people in the trades M&A space never look at them.

We do. And they tell a story that financial statements won't show for another six months.

At Chisel Industries, we track 100s of millions of building permits nationwide as part of our proprietary data platform. It's one of several signals we use to understand the health, trajectory, and competitive dynamics of every trade vertical we invest in.

Here's what the data is telling us right now.

HVAC Is Accelerating

HVAC permit volume continues to outpace other residential trade categories, with filings running strong even in traditionally slower winter months. The drivers are structural, not seasonal: aging housing stock, heat pump adoption, and tightening energy efficiency regulations are creating sustained demand that doesn't follow the old playbook.

For HVAC operators, this means a longer selling season and more predictable revenue. For acquirers who aren't watching the data, it means they're still underwriting off last year's assumptions.

Electrical Is the Quiet Giant

Electrical permits now represent the single largest trade category by volume — a trend that's been building for three years. EV charger installations, panel upgrades for electrification, and solar interconnects are driving a structural shift.

This isn't cyclical. The electrical trades are being permanently repriced by the energy transition, and the companies positioned for it are pulling away from those that aren't.

Roofing Remains Steady

Roofing permit activity held firm, consistent with recent trends. The vertical continues to benefit from a fundamental truth: the average American roof is replaced every 20–25 years, creating a rolling demand cycle that's largely independent of new construction starts.

The companies that understand their local replacement cycle have a built-in pipeline that most outside acquirers can't see from a spreadsheet.

Pools: Seasonal but Telling

Pool and hot tub permits follow predictable seasonal patterns — lower in winter, higher in spring. But the trailing twelve-month trend tells a more interesting story: pool construction has stabilized after the post-COVID correction, and service-heavy operators continue to generate highly predictable recurring revenue.

What the Data Tells Us

Most buyers in the trades space evaluate targets based on trailing financials, a site visit, and a gut check. That worked when information was scarce and competition was low.

It doesn't work anymore. The best acquisitions in home services will be made by teams that can read demand signals before they show up on an income statement. Permit data is one of those signals. We track dozens more.

The trades market isn't a black box. It's a data problem — and we built the infrastructure to solve it.
