Summary

What do they do? California YIMBY Education Fund produces housing research and implementation analysis and supports the national Metropolitan Abundance Project. It is legally distinct from California YIMBY's advocacy and political entities. The conditional estimate prices a California housing-health component against all recipient spending; other geographic and policy benefits remain unpriced.

Why we’re interested in this organization:

  • A plausible high-leverage pathway runs from better implementation rules to additional homes, lower housing costs and improved living conditions.

  • Original research discusses financial feasibility and local implementation, not merely legal zoning capacity.

  • Independent empirical supply research supports an affordability mechanism, while the report keeps that distinct from health outcomes.

Our main reservations:

  • No reviewed source identifies the marginal extra completed homes caused by an ordinary Education Fund donation.

  • California benefit allocation is not the same as its Sacramento address: MAP explicitly works nationally and the c4 shares employees.

  • The accounts change from cash in 2022–23 to accrual in 2024, and housing or financial gains cannot automatically be priced as QALYs.

What do you get for your dollar? $454.8M per better life: ten additional quality-adjusted life years in California. Conditional partial-health estimate at full recipient cost; other portfolio benefits unpriced..

Central 2.5 net additional occupied home-equivalents, 20.101335745065107 discounted California home-years, 0.20101335745065108 QALYs. Hypothetical outputs, not reported completions.

1. What do they do?

The recipient's research catalogue covers ADU implementation, housing impact fees, underproduction and local approval processes. Its national MAP project works on housing, transportation and governance; MAP's giving page identifies the Education Fund as its recipient. The main giving instructions distinguish this c3 from California YIMBY's c4 and PAC. Shared branding does not justify assigning every affiliate policy win to this charitable gift.

2. Monitoring and information sharing

The ADU retrospective documents a substantial permitting expansion but is a historical, uncontrolled policy account, not a marginal donor evaluation. Its chart separates permits from completions; footnotes note changing data collection and unverified affordability classifications. No new gift receives credit for all past ADUs. A useful next evaluation would link a specific Education Fund analysis or implementation intervention to changed rules, actual net completions, occupancy, resident outcomes and a credible no-intervention comparison.

3. Qualitative assessment

Research on large new apartments supports rent reductions nearby rather than inevitable rent inflation, but is not a health trial and may not transfer to small ADUs or every neighborhood. Terner's early SB9 review shows why legal or modeled feasible capacity is not production: financing, local restrictions and construction constraints matter. HCD's current SB79 guidance confirms the law is already operative and public agencies have implementation duties; future gifts need to improve on that funded baseline. Housing can affect health through stability, crowding, location and pollution, but MTO concerns a different low-income mobility intervention with heterogeneous effects. The recent income trial also cautions against treating financial relief as an automatic lasting clinical gain.

4. What do you get for your dollar?

The conditional California housing-health price is $454.77 million per ten California QALYs. It charges three years of all recipient spending, $9,141,486, including national and unpriced activities. It is not a complete portfolio or societal return. We posit 1,000 net additional occupied California homes conditional on an implementation change over that support window; this is an explicit scale judgment, not permitted capacity, a project pipeline or a forecast from the ADU report.

A 10% incremental coalition implementation probability, 10% Education Fund contribution and 25% ordinary-funding response imply 2.5 net additional home-equivalents. The c3 contribution excludes credit assigned to its c4 and public agencies. Ten years of benefit at years 3–12 gives 8.040534 discounted home-years per added home. A judgmental 0.01 QALY per home-year across affected residents yields 0.201013 California QALYs, without multiplying again by household occupancy. The utility prior is not inferred from rent dollars, the MTO trial or a housing unit count.

Net homes exclude displacement of construction elsewhere in California. Health may arise through less harmful crowding or instability, but some residents simply move from other adequate housing, and transportation or pollution effects can offset gains. Current SB79 duties and already permitted development are baseline. A construction-resource sensitivity adds $500,000 per attributable net home; this is a judgmental resource proxy, not a current local unit quote or net fiscal cost.

Model, assumptions and sensitivity

Three years of whole-recipient FY2024 accrual cost, including national MAP and support functions. Partial California housing-health estimate. Private construction, public infrastructure and unrecognized shared/volunteer resources not in central donor cost; sensitivity added.

N explicitly counts net additional occupied California homes, not all national MAP output. u is total California resident health per net home-year and includes occupancy/displacement within its subjective value; no population or household multiplier. The home-year utility is an expected net health area across changing occupants and already includes survival, occupancy turnover and benefit fade by judgment; it is not a fixed utility promised to every initial resident for ten years.

C=3*E; U=N*p*a*b; A=sum_{t=3}^{12}(1+d)^(-t); Q_CA=U*A*u. P10=10*C/Q_CA. Only ten finite home-years; N net of replacement/displaced construction. Resource stress C'=C+U*500000. Other health remains unknown.

E
3047162 USD/year recipient accrual expense (observed). Original2024 return; no netted event/COGS costs. [cay24]
N
1000 conditional net additional occupied California homes (judgment). Judgment of implementation scale, not existing permits or empirical pipeline.

b
0.25 ordinary-funding response (judgment). Reserve, substitution and capacity judgment.
u
0.01 QALY/net occupied home-year (judgment). Judgment across all affected residents; no extra occupancy multiplier, no rent-to-health conversion. [mto] [income-health]

Conditional California net-home health: Cost: $9.1M; California QALYs: 0.20101335745065108; all-population QALYs: 0.20101335745065108. N=1000;p=.1;a=.1;b=.25;u=.01;d=.03;years3–12.

Weak implementation and health: Cost: $9.1M; California QALYs: 0.000048243205788156256; all-population QALYs: 0.000048243205788156256. N=100;p=.02;a=.03;b=.1;u=.001;timing central.

Favorable finite housing influence: Cost: $9.1M; California QALYs: 60.304007235195314; all-population QALYs: 60.304007235195314. N=10000;p=.3;a=.25;b=.5;u=.02;timing central.

No added net homes or health: Cost: $9.1M; California QALYs: 0; all-population QALYs: 0. No net additional construction or health effect.

Net adverse stress: Cost: $9.1M; California QALYs: -1; all-population QALYs: -1. One California QALY lost via displacement, harmful location or opportunity costs; judgment.

Complete portfolio unknown: Cost: $9.1M; California QALYs: unknown; all-population QALYs: unknown. Other effects unpriced.

Add attributable construction resource stress: Cost: $10.4M; California QALYs: 0.20101335745065108; all-population QALYs: 0.20101335745065108. 2.5 net home-equivalents*$500000; same health, not a market quote.

Counterfactual: SB79 is operative, HCD and local governments have statutory duties, existing finance/building pipelines and other advocates continue. Credit only additional completed occupied homes beyond these and net of construction elsewhere, not all newly legal capacity.

Attribution: p incremental coalition implementation, a c3 Education Fund contribution distinct from c4/shared staff, b gift funding response; each once. Conditional N is before those factors, not a donor-attributable forecast.

N, policy probabilities and health conversion are uncalibrated judgments. Large price range does not validate any particular yield. Financial relief and mobility trials do not establish health per market-rate home. Whole portfolio remains unpriced.

Sensitivity

  • Central $454770076.7718504/10 California QALYs. $500000 per net home resource stress adds $1250000.
  • If new supply mostly reallocates already adequately housed residents without health improvement, u can be zero.
  • Unit construction/resource cost is not a net social cost; benefits, capital residual value and opportunity costs require separate accounting.
  • No synthetic historical mean across cash/accrual years.

Unresolved inputs

  • c3-specific gift-sensitive implementation plan and net completion yield.
  • Coalition/c3 attribution versus public baseline and c4 resources.
  • California occupant outcomes, counterfactual housing and net crowding/stability effects.
  • Full construction/infrastructure resource costs, unrecognized shared resources and omitted portfolio effects.

5. Funding and previous grants

The 2024 return reports $3,047,162 expenses and $1,628,879 revenue, with $4,318,400 unrestricted and $845,879 restricted net assets. Spending is $2,833,521 program, $150,595 management and $63,046 fundraising. Schedule R identifies shared employees with the c4; Schedule D records $386,898 due to a related party. Original 2022 and 2023 returns check cash accounting, while 2024 checks accrual. The displayed historical series is therefore not a clean three-year mean. A deficit supports asking about future capacity, but neither it nor reserves establishes the effect of a marginal gift. Construction capital, public infrastructure and costs to other advocates are outside the recipient denominator and must be disclosed in any future societal comparison.

Fresh checks of all three original returns confirm no separately netted event or inventory costs. The 2024 accrual versus 2022–23 cash distinction remains; no synthetic comparable mean is produced. The 2024 and 2023 Schedule D expense-reconciliation sections are blank, not evidence of zero donated services; the 2022 Schedule D endpoint was unavailable. Unrecognized shared or volunteer resources remain a cost limitation. The c3-specific source perimeter is retained.
