When more housing becomes a hard sell

A Slow Boring article by Halina Bennett examines a central paradox in housing policy: density reforms and pro-housing measures can pass in city halls and legislatures, but they often fail when put directly to voters at the ballot box. The piece explores why public support for more housing in the abstract does not translate into support for specific projects or zoning changes in practice. This tension is playing out against a backdrop of a documented national housing shortage estimated at roughly 10 million homes.

⚡Both sides have significant internal splits on this story. Arguments below represent the dominant positions on each side — see The Divide below for the full picture.

Building more homes was supposed to fix the affordability crisis. So why are communities rejecting new housing projects even in expensive markets? The answer reveals why supply-side thinking keeps running into a wall.

Who ballot outcomes actually represent
Conservative
When voters are handed a direct say on density mandates, they reject them — not sometimes, consistently. The YIMBY movement's response to this pattern is the most revealing thing about it: it has quietly concluded that democracy produces the wrong answer on housing, and that state preemption is the fix. That is not a technocratic adjustment. That is a confession that the policy cannot survive contact with the people it claims to serve.
Liberal
You're describing a ballot electorate as if it were 'the people,' but the people most affected by the housing shortage — renters, younger residents, working families priced out of the neighborhood entirely — don't show up in those results because they've already left. When you call that outcome democratic, you're measuring the preferences of the people who won the last housing war, not the people losing the current one. Winning a vote among the remaining players isn't the same as getting the question right.
Conservative
The people who 'already left' are still citizens of their state, and state legislatures — which you apparently trust to override local votes — are elected by that same imperfect universe of actual voters. You can't discredit the mechanism only when it produces results you dislike.
Liberal
State preemption isn't discrediting the mechanism — it's the mechanism working correctly: higher-level democratic bodies setting a floor that local majorities can't use to externalize their costs onto everyone else. We do this with civil rights law, environmental law, and labor law. Housing isn't different in kind.
Permitting costs versus zoning as primary barrier
Conservative
The density-mandate argument consistently refuses to engage that regulatory burden is not just zoning. Permitting timelines, environmental review under statutes like CEQA, prevailing wage requirements, and impact fees can add over $100,000 per unit to construction costs before a single board is nailed. San Francisco cannot house people not primarily because fourplexes are illegal, but because the regulatory gauntlet from approval to occupancy takes a decade and costs a fortune. Cut that first.
Liberal
Permitting reform is real and worth doing — but you're using it as a reason to leave zoning alone, and that's where the logic breaks. You can streamline CEQA and still hit a wall if the thing you're trying to permit is illegal to build on 75% of residential land. Minneapolis's results weren't produced by faster permitting — they were produced by legalizing more units in more places. Those are two separate levers and you need both.
Conservative
Minneapolis is not San Francisco. The reason streamlining produced results in Minneapolis is that land costs, labor costs, and baseline construction economics are categorically different. Transplanting the Minneapolis lesson to coastal metros without accounting for those structural differences is exactly the kind of policy reasoning that sounds rigorous and isn't.
Liberal
Then the conservative case proves too much: if coastal conditions are so structurally different that supply reform can't work there, what exactly is your solution for San Francisco — wait for the Fed to cut rates and hope builders recover from 2008? That's not an answer. It's a shrug dressed as an argument.
Sun Belt building versus coastal unaffordability
Conservative
Texas and Florida have built aggressively under permissive zoning and now have builders subsidizing mortgage rates to 0.99% to move inventory. Meanwhile coastal metros remain catastrophically unaffordable despite some additional density occurring there too. If zoning density were the primary driver of the shortage, that divergence shouldn't exist. The shortage is geographically specific, and that specificity points to land costs, environmental review, labor markets — not insufficient density mandates.
Liberal
The Sun Belt comparison actually makes the supply case, not yours. Texas and Florida are affordable precisely because they built. Coastal cities that refused to permit density are unaffordable precisely because they didn't. You're citing the evidence for the supply argument as if it were evidence against it. The difference between those markets is not monetary policy or labor costs — it's that one set of cities said yes to construction and the other spent four decades saying no.
Conservative
Labor costs, land acquisition, and environmental review timelines are not identical across those markets — the divergence you're calling proof of a zoning thesis is also fully consistent with a regulatory-cost thesis, and you haven't shown which variable is actually doing the work.
Liberal
We have a natural experiment: same country, same Fed, same post-2008 construction slump, radically different affordability outcomes that track directly with permissiveness of land use. At some point 'correlation isn't causation' becomes a way to avoid the obvious.
Lock-in effect as primary supply constraint
Conservative
The Fed's rapid rate hikes produced a lock-in effect by 2023 in which homeowners holding sub-3% mortgages refuse to sell, directly constraining resale inventory in a way that no zoning reform can address. The people most frozen out of the housing market are waiting for mortgage rates to fall and for the Fed's damage to be unwound — those are the binding constraints right now, and upzoning a neighborhood doesn't touch them.
Liberal
The lock-in effect is real, but it's an argument for building more new units, not for accepting current zoning. If existing homeowners won't sell, the relief valve is new construction — which is exactly what density mandates produce. You've identified a supply constraint and then argued against the supply response. That's internally contradictory.
Conservative
New construction in coastal markets takes five to ten years from approval to occupancy under current regulatory conditions. The lock-in effect is a present-tense problem. Upzoning today doesn't unclog inventory this decade.
Liberal
Which is exactly why you also streamline permitting — the two reforms compound, they don't compete. But if your argument for not upzoning is that permitting takes too long, the answer is to fix permitting, not to keep the underlying use illegal.
Market-rate construction and displacement tradeoff
Conservative
The conservative supply-side answer — deregulate construction, streamline permitting, get government out of the way of builders — is genuinely pro-housing without requiring the state to override neighborhood self-determination. There is a difference between liberating markets and conscripting communities. Builders responding to demand signals will produce what the market needs without mandates that override local democratic choices.
Liberal
Pure market response is also where the filtering argument breaks down in ways you should take seriously: new market-rate construction in already-tight markets can accelerate displacement before it moderates rents. The 30-year-old paying 50% of income in Los Angeles will not be helped by a luxury tower opening in 2028. That's a real critique of supply-only thinking, which is why the complete answer has to include social housing and tenant protections alongside upzoning — not instead of it.
Conservative
You've just argued that market-rate construction might not help low-income renters fast enough, which is a genuine point — but social housing investment and tenant protections require either tax revenue or landlord mandates, both of which your coalition struggles to pass even in cities it fully controls. The political track record of the 'alongside, not instead of' coalition is not encouraging.
Liberal
The political difficulty of passing the complete package doesn't make the incomplete package correct. Deregulating construction for market-rate builders while blocking tenant protections and public investment is a choice about who gets the gains from reform — and it's a choice, not a neutral market outcome.
Conservative's hardest question
The libertarian-conservative case for permitting deregulation is genuinely strong, but it struggles to explain why the most deregulated Sun Belt markets have addressed affordability locally while the places where people most want to live — coastal job centers — remain unaffordable despite the fact that some additional density has occurred there too. If deregulation alone were sufficient, California's streamlining efforts over the past decade should have shown more meaningful results, which means the honest conservative answer must eventually grapple with the possibility that land scarcity in specific high-demand markets may require more aggressive supply responses than permitting reform alone can deliver.
Liberal's hardest question
The filtering mechanism — whereby new market-rate construction eventually reduces costs for lower-income households — operates over decades, not years, meaning supply reform as currently practiced offers little near-term relief to the most rent-burdened families. Critics who argue that building more luxury units can actually accelerate gentrification and displacement in the short run in already-tight markets are making a point that pure supply-side analysis genuinely struggles to rebut without invoking a longer time horizon most affected families cannot afford to wait for.
The Divide
*Both sides are fracturing over whether housing is fundamentally a supply problem, a power problem, or both.*
MAGA/POPULIST
Opposes top-down density mandates; blames immigration and federal overreach; prioritizes local control and homeowner rights.
“We're not going to force densification on beautiful suburban communities.” — Donald Trump
LIBERTARIAN/FREE-MARKET
Supports zoning deregulation as supply-side solution; argues building more housing of all types solves affordability.
ABUNDANCE/YIMBY PROGRESSIVE
Building more housing through deregulation and upzoning is the primary lever for affordability and racial equity.
“Density reforms can win in city hall, but they can be a harder sell at the ballot box.” — Halina Bennett (Slow Boring)
HOUSING JUSTICE/ANTI-DISPLACEMENT LEFT
Supply alone is insufficient; rent control, community land trusts, and social housing are necessary to prevent displacement.
The Verdict
Both sides agree
Both sides agree that the Federal Reserve's 2022-2023 rate hikes created a genuine 'lock-in effect' that constrains resale inventory independent of zoning policy, and that this monetary policy failure has meaningfully worsened affordability in ways no local land-use reform can fully address.
The real conflict
FACTUAL: Whether ballot rejection of density measures reflects genuine public opposition or structural overrepresentation of older homeowners—conservative position rests on treating ballot outcomes as democratic verdicts on policy merit; liberal position treats them as captured outcomes reflecting only winners of prior housing wars.
What nobody has answered
If Minneapolis achieved the slowest rent growth among major metros by upzoning through elected city council (not a voter ballot), why hasn't that model been replicated in other cities, and is the actual barrier to density reform voter opinion itself or the political difficulty of assembling legislative coalitions that can override organized homeowner interests—meaning state preemption might be the only mechanism that works regardless of ballot outcomes?
