The consensus in housing policy is now almost boringly consistent: we don't build enough homes, zoning is too restrictive, and if we just remove regulatory friction, the market will solve itself. Massachusetts is eliminating single-family zoning. Developers are mobilizing capital at record levels. Everyone agrees the problem is permission, not capacity.
But this consensus is too comfortable. The better question is what this trend breaks next.
Because there's a structural problem hiding beneath the optimism: we can rezone America into a parking lot, but we cannot rezone our way out of a construction workforce that is aging, depleting, and in many regions already stretched beyond realistic capacity. The real constraint on housing supply isn't planning boards. It's the people who actually build.
Let's be honest about what's happening. The construction workforce has been hollowed out for fifteen years. The 2008 crisis accelerated retirements and pushed an entire generation into other industries. Trade schools emptied. Immigration, which historically supplied construction with younger workers, faces tighter restrictions. The average age of a carpenter in America is now higher than the average age of the general workforce. We are losing institutional knowledge faster than we're replacing it.
When developers talk about housing shortfalls, they're usually discussing zoning constraints or permitting timelines. Those are real problems. But ask a general contractor about their biggest headache in 2024, and the conversation quickly turns to labor. They can't find crews. Skilled trades are bidding projects up 20, 30, sometimes 40 percent above historical rates. Projects that should be feasible sit in planning limbo not because of city councils, but because there aren't enough people to build them.
This is the collision point no one wants to discuss. Policymakers pass zoning reforms with great fanfare. Homebuilders announce new projects. Capital flows into development. And then construction starts, and reality meets the labor shortage like a forklift meets a wall.
The math is unforgiving. If we're serious about building the housing supply most analyses suggest we need, we're talking about a massive increase in construction starts. But increases in starts require increases in labor availability. We cannot pull construction workers out of thin air. They require training, experience, and honestly, a cultural shift toward trades as legitimate careers.
Some regions have begun addressing this seriously. Apprenticeship programs are being expanded. Wages for skilled trades are rising, which is rational market adjustment but also signals desperation. A few states are exploring ways to streamline trade certifications across state lines, which would help. But these are band-aids on a structural wound.
Here's what breaks if we don't address this: the price mechanism. If zoning restrictions are removed but labor is scarce, construction costs don't fall. They rise. Developers can build more units, but those units become more expensive to produce. Homebuyers don't actually benefit if supply increases but prices rise faster because labor is choked off. The housing crisis might shift from "not enough homes" to "homes exist but are unaffordable because construction is inefficient."
We also risk seeing substitution effects. Labor-intensive construction gets deprioritized for labor-light projects. We might see more commercial development and fewer residential units, or more luxury housing that justifies higher labor costs and fewer middle-market projects that can't. Capital chases projects that work within labor constraints, not projects that solve the housing crisis.
None of this means zoning reform or permitting reform is wrong. It's necessary. But necessary isn't sufficient. The comfortable consensus treats housing supply as a regulatory problem with a regulatory solution. It's also a labor problem with no obvious regulatory solution.
Until we're serious about rebuilding the construction workforce, removing zoning restrictions is like opening the throttle on a car with an empty gas tank. We'll feel productive, but we won't go anywhere.
