Casita Coalition

What Casita Coalition does

Casita Coalition is a 501(c)(3) public benefit nonprofit founded in 2020 and headquartered in Los Angeles, California, that promotes policies and programs expanding middle housing options — primarily accessory dwelling units (ADUs), duplexes, triplexes, cottage courts, and townhouses. The organization's founders authored California's uniform statewide ADU statutes and have since positioned the coalition as a national policy intermediary, with 11 U.S. states now having effective statewide ADU laws. Its core offerings are educational and convening-based rather than technology-based: the Build the Middle Playbook co-developed with Zillow; homeowner guidebooks covering ADU finance, garage conversions, and legalization of unpermitted ADUs; Casita Academy training for housing professionals; the annual Build the Middle National Housing Convening (San Diego 2023, Pasadena 2025); and the Building the Middle webinar series running since 2021.

Casita Coalition operates a membership-based, community-led go-to-market targeting three primary segments: California homeowners seeking to build, finance, or legalize ADUs; housing professionals (developers, builders, lenders, brokers, designers, policy specialists); and jurisdictions and policymakers working on zoning and middle housing reform. Revenue is generated through membership dues, grants, and convening sponsorships. The funder base is concentrated among institutional philanthropy (Chan Zuckerberg Initiative, Arnold Ventures, San Francisco Foundation, Sobrato) and corporate sponsors (JPMorgan Chase, Wells Fargo, Zillow, Meta, Airbnb, Bilt Rewards, Cotality, National Association of Realtors, Federal Home Loan Bank of San Francisco). In 2025, the coalition announced a merger with California Community Builders, extending its scope into racial wealth gap and homeownership equity, with program integration continuing into 2026. There is no proprietary technology platform; the core technology description in source material is "not applicable."

Scale indicators2 records

Recent moves6 records

Expansion highlights6 records

Direct peers

• National Housing Conference: Nonpartisan nonprofit focused on affordable housing policy at the federal, state, and local levels. Comparable through shared membership model, convener role, and emphasis on policy-driven housing supply expansion.
• California YIMBY: California-focused pro-housing advocacy nonprofit pushing state and local zoning reform for more housing. Directly comparable to Casita Coalition's housing-policy advocacy mission in California and frequently referenced in coalition materials.
• Grounded Solutions Network: National membership network focused on inclusionary zoning, community land trusts, and permanently affordable homeownership. Comparable membership nonprofit model serving housing professionals and policymakers on middle-income housing solutions.
• Smart Growth America: National nonprofit advocating land-use and zoning policies that enable more housing and walkable neighborhoods. Comparable mission (policy advocacy for middle housing types) and constituency (policymakers and practitioners), though with broader smart-growth framing.
• YIMBY Action: National grassroots pro-housing advocacy network pushing zoning reform and middle housing supply. Overlaps with Casita Coalition's policy reform and community-organizing work at the state and local levels.
• PATH (People Acting To Help) / Local Housing Solutions Coalition: Initiative supporting local jurisdictions on housing policy and implementation (originally a joint project with the Center for Housing Policy). Comparable through its focus on practical, local-level middle housing policy adoption similar to Casita Coalition's training efforts.

Broad incumbents

• Habitat for Humanity International: Major nonprofit focused on homeownership and affordable housing supply and policy. While Casita Coalition is policy-only and Habitat builds/finances directly, both target the affordable and middle-income homeownership gap.
• Enterprise Community Partners: Large national nonprofit that finances and develops affordable and middle-income housing, plus policy and advocacy. Larger and more capital-deployment focused, but pursues the same end-state of expanded middle housing options with significant policy influence.
• National Low Income Housing Coalition: National advocacy organization advancing policies to end poverty housing. Larger and federal-focused, but shares the nonprofit policy-advocacy, membership/convening model Casita Coalition uses and targets housing affordability for low- and middle-income households.
• Urban Land Institute: Global research and education nonprofit on land use and real estate, with strong housing-policy work (including middle missing-middle housing). Overlaps with Casita Coalition's professional training and convening functions at a much larger scale.
