Why Feasibility Decisions Shape Housing Supply More Than People Think
Housing policy conversations tend to focus on the decisions that are visible: which parcels get rezoned, which projects get approved, which budgets get allocated. These decisions matter. But there's an earlier set of decisions — largely invisible to policy makers and the public — that shapes housing supply at least as much.
Feasibility decisions.
Before any project is proposed, approved, or built, a development team decides whether a site is worth pursuing. That decision — made privately, without public record, based on program parameters and financial analysis and organizational capacity — determines which sites enter the development pipeline and which don't. The aggregate of those decisions is a significant driver of housing supply.
The feasibility decision as a housing supply lever
Consider what a feasibility decision actually involves. A development team evaluating a site is asking: given this site's physical characteristics, location, and program eligibility, and given the current state of our capital markets, subsidy programs, and organizational capacity, is there a path to a financially viable project here?
When the answer is yes, the site enters the pipeline. When it's no, it doesn't — and in most cases, it stays out of the pipeline indefinitely. Residential development isn't like commodity production where supply responds rapidly to price signals. A site that doesn't get developed this cycle often doesn't get another serious look for years.
This means the cumulative effect of individual feasibility decisions is large. Markets where many sites get evaluated and found viable develop more housing. Markets where sites consistently fail the feasibility screen — because programs don't stack well, because construction costs are too high, because the soft debt supply is thin — produce less housing, regardless of stated policy goals.
The information dimension
Feasibility decisions are only as good as the information that underlies them. A team that doesn't know about a relevant soft loan program will reach a different conclusion about a site's viability than a team that does. A team using outdated construction cost benchmarks will model different outcomes than a team with current data. A team that misjudges QCT status or density bonus eligibility will draw different conclusions than a team with accurate regulatory information.
This information dimension is important because it means that housing supply is not just a function of what programs exist — it's a function of whether development teams have accurate, accessible information about what programs apply to specific sites.
Policy that creates programs but doesn't invest in making those programs accessible and legible to development teams captures less of its intended impact. The gap between what a program makes theoretically possible and what it actually produces is, in part, an information gap.
What this means for policy design
For policy makers thinking about how to maximize the housing supply impact of their programs and funding, the feasibility decision stage deserves explicit attention:
Program complexity has a cost. Each additional subsidy layer, compliance requirement, or application process adds complexity to the feasibility decision. Some of this complexity is necessary — it ensures programs serve their intended populations and protect public investment. But complexity that doesn't serve those goals reduces utilization and therefore impact.
Information accessibility is part of program design. A program that's well-funded but poorly communicated — whose terms are hard to find, whose eligibility requirements aren't clearly specified, whose interaction with other programs is opaque — will be underutilized. Program design should include explicit attention to how program information reaches development teams in actionable form.
Development capacity is a housing supply input. The ability of development teams to evaluate sites, advance projects, and close deals is as much a determinant of housing supply as the availability of subsidy capital. Policy that funds programs but doesn't attend to development capacity is implicitly assuming unlimited development capacity — an assumption that consistently fails in practice.
The aggregate picture
Viewed in aggregate, feasibility decisions are one of the most consequential and least visible drivers of housing supply. The housing that gets built is almost entirely determined by which sites made it through the feasibility stage — which sites were evaluated, by which teams, with what information, at what moment in the program cycle.
That aggregate picture suggests that investments in the feasibility infrastructure — better information access for development teams, tools that reduce evaluation time, software that makes program complexity navigable — have direct housing supply consequences that are difficult to see at the individual deal level but substantial in aggregate.
The most consequential housing decisions aren't the ones made by city councils or zoning boards. Many of them are made in spreadsheets, by development teams working through the question of whether a specific site has a viable path to a financeable project. Those decisions deserve more attention from policy makers, investors, and the public than they currently receive.
