Co-housing reduces per-capita costs but provides limited structural affordability solutions
Homesharing and co-housing reduce per-capita housing costs for participants, but measurable city-scale affordability pressure reduction is limited. Most co-housing serves upper-middle-income households and provides no path to ownership.
Homesharing and co-housing demonstrably reduce per-capita housing costs. However, the evidence for *measurable reduction of affordability pressure* at city/regional scale is limited. Most co-housing reaches upper-middle-income households; multigenerational living is driven by constraint, not preference, and provides no path to ownership. This is a real cost-containment strategy but not a structural solution to the affordability crisis.

Premise Assessment
Is the claim as stated true? Four dimensions, each 0–25, sum to 100. The verdict label is derived from this score. Full rubric →
Quality and quantity of direct evidence for or against the claim — RCTs, systematic reviews, natural experiments, large cohort studies.
Per-capita cost reduction from shared living is well-documented, but evidence for city-scale affordability impact is limited — genuinely mixed depending on the scale examined.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The per-capita-savings mechanism is straightforward arithmetic, but the leap to structural affordability solution is unsupported since most co-housing serves upper-middle-income households, not the population facing the affordability crisis.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Housing researchers agree homesharing provides real individual cost containment while disagreeing on how much weight to give it as policy versus a personal coping strategy.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
The individual-savings-without-city-scale-impact pattern replicates across studies of co-housing demographics and multigenerational living driven by constraint rather than preference.
Individual vs. Structural
How much of the outcome is explained by structural forces versus individual agency? Four dimensions, each 0–25. Higher scores indicate stronger structural causation. Full rubric →
