No set maximum; typical awards $200,000–$400,000; duration averages 2–4 years.

Supports research to measure or evaluate the impact of recent state and local housing supply policy reforms in the U.S.

--- ## Description Arnold Ventures is seeking proposals for research projects that measure or evaluate the effects of recent state and local policy reforms aimed at legalizing or encouraging new housing supply. The program’s goal is to generate rigorous evidence on how such reforms—such as zoning changes to allow accessory dwelling units, duplexes, or apartments—impact land transactions, housing production, and market outcomes like property values or rental prices. Both causal evaluation studies and high-quality descriptive projects using creative data sources are encouraged. This initiative is part of Arnold Ventures’ broader mission to advance evidence-based solutions for affordable and accessible housing. --- ## Due Dates - March 27, 2026: Letter of Interest (LOI) submission deadline - June 19, 2026: Deadline for invited applicants to submit full proposal Applicants will be notified if invited to submit a full proposal by April 24, 2026. Award notifications are expected by August 7, 2026 (proposals over $500,000 may require additional approval time). --- ## Funding Amount - There is **no set maximum budget**; budgets must be well-justified and aligned with project scope. - Typical awards range from **$200,000 to $400,000**. - Average project duration is **2–4 years**, but periods of performance may range from less than a year to over 10 years depending on project complexity. Indirect cost rates apply per Arnold Ventures’ policy (e.g., 10% for universities, 15–20% for nonprofits depending on size). --- ## Eligibility - Open to U.S.-based and international applicants, but **projects must focus on U.S. state or local housing policies and outcomes**. - For-profit and nonprofit organizations, universities, and research institutions are eligible. - Studies on federal policies, mortgage markets, or demand-side interventions (e.g., rental assistance) should apply to the [Building Evidence RFP](https://www.arnoldventures.org/evidence-evaluation-rfps) instead. - Multiple LOIs may be submitted for distinct projects. --- ## Application Process 1. **Letter of Interest (LOI):** - Maximum 5 pages, submitted via the [Arnold Ventures applicant portal](https://proposals.arnoldventures.org/prog/housing_supply_reforms_rfp/http://). - Must include project description, research questions, outcomes of interest, research design, and timeline. - Optional uploads: team overview (1–2 pages), CVs (1–3 pages per key member), and a budget summary. 2. **Full Proposal (by invitation):** - Detailed project plan and budget using AV’s template. - Additional documentation may be requested. 3. **Review Process:** - Proposals are evaluated for study contribution, methodological rigor, feasibility, and alignment with AV priorities. - The process from LOI to grant agreement typically takes about 6 months. --- ## Additional Information - **Open Science Requirements:** Grantees must pre-register studies (for quasi-experimental methods) on the [Open Science Framework](https://osf.io/) and make de-identified data, code, and research outputs publicly available, subject to data sharing agreements. - **Budget Guidance:** Indirect costs are capped per [AV’s Indirect Cost Policy](https://assets.arnoldventures.org/uploads/AV-Indirect-Cost-Policy.pdf). - **Programmatic Costs:** Generally supports research-related expenses; limited programmatic costs may be allowed when necessary for project execution. - **Equity and Transparency:** AV encourages inclusive research methods and transparency in all funded projects. --- ## External Links - [RFP Document (PDF)](https://assets.arnoldventures.org/uploads/PDFs/AV_RFP_Infrastructure-Housing.pdf) - [Arnold Ventures Infrastructure RFPs](https://www.arnoldventures.org/infrastructure-rfps) - [Arnold Ventures Indirect Cost Policy (PDF)](https://assets.arnoldventures.org/uploads/AV-Indirect-Cost-Policy.pdf) - [Open Science Guidelines for Research Grants](https://www.arnoldventures.org/open-science-guidelines-for-research-grants) - [Applicant Portal](https://proposals.arnoldventures.org/prog/housing_supply_reforms_rfp/http://) - [Building Evidence RFP](https://www.arnoldventures.org/evidence-evaluation-rfps) --- ## Contact Information | Purpose | Contact | |---------------------------------|--------------------------------------------| | General inquiries, eligibility, or budget | [housingRFP@arnoldventures.org](mailto:housingRFP@arnoldventures.org) | | Funder main contact | [info@arnoldventures.org](mailto:info@arnoldventures.org) | | Funder website | [https://www.arnoldventures.org/contact](https://www.arnoldventures.org/contact) | ---
