The California Paradox
California has more grant funding than any other state. The cap-and-invest program (renamed from cap-and-trade in September 2025) has generated approximately $28 billion to date and funds 40+ grant programs across dozens of agencies. Proposition 4, the $10 billion climate bond voters approved in November 2024, is beginning to deploy $3.5 billion in its first authorized tranche. The state budget allocates $500 million for a seventh year of homelessness funding and $314 million for wildfire resilience. But the systems for distributing the money are among the most complex in the country. Affordable housing developers routinely stack five to seven different funding sources for a single project. The grants.ca.gov portal saw 11% more visitors in 2024-25 but 14% fewer posted opportunities, meaning competition is intensifying. And a Little Hoover Commission survey found that nearly 25% of nonprofits wait over three months for state payment, with 40% never receiving advance payments despite legislation authorizing them. The state is also losing roughly $1.4 billion in federal funding in 2026-27 due to the One Big Beautiful Bill Act, with Medi-Cal costs increasing by about $1 billion and CalFresh/SNAP losing $300 million. So California has more money and more headaches than anywhere else. This guide focuses on what is actually open, what is new, and how to work the system.
Proposition 4: The Biggest New Funding Source in Years
Proposition 4 authorized $10 billion in general obligation bonds for climate and environmental projects. The 2025-26 budget authorized the first $3.5 billion in spending, and the state has created 80 new positions to administer the programs. Guidelines are still being written for many programs, which means organizations that participate in the public comment process and build relationships now will have an advantage when applications open. The $10 billion breaks down by category: $3.8 billion for water projects (quality, flood protection, drought resilience), $1.95 billion for wildfire and extreme heat, $1.9 billion for natural lands, parks, and wildlife, $1.2 billion for coastal lands, bays, and ocean protection, and $850 million for clean energy. At least 40% must benefit disadvantaged communities and at least 10% must benefit severely disadvantaged communities. Specific Prop 4 programs now active include Department of Water Resources grants ($231.5 million for dam safety and climate resilience, plus $183.2 million for water quality and tribal water infrastructure) and CalFIRE wildfire prevention grants funded by both Prop 4 bonds and cap-and-invest proceeds. CalFIRE's Forest Health Program had a draft guidelines comment period through February 24, 2026, meaning final program rules are being set right now. The practical question is timing. With guidelines still being drafted and new staff still being hired, many Prop 4 programs will open for applications throughout 2026 and 2027. Organizations that want to compete should be tracking the rule-making process through the individual administering agencies, not just watching grants.ca.gov.

Cap-and-Invest: California's Permanent Funding Engine
No other state has anything comparable. California's cap-and-invest program is the fourth-largest emissions trading system in the world (behind China, the EU, and South Korea). AB 1207 and SB 840, signed in September 2025, extended the program through 2045 and renamed it from cap-and-trade to cap-and-invest. The Greenhouse Gas Reduction Fund (GGRF) is projected to generate roughly $3.4 billion in 2026-27, plus approximately $600 million in interest income, totaling about $4 billion. This flows to more than 40 grant programs across agencies including CARB, CalFIRE, the Strategic Growth Council, and the Department of Community Services and Development. But the new SB 840 framework also requires roughly $4.3 billion in annual allocations, creating a potential funding gap of $300 to $800 million. Required allocations include $1 billion annually for high-speed rail, $800 million for affordable housing, and $250 million for community air protection. Programs that are "subject to appropriation" rather than guaranteed will be first to face shortfalls. CARB is the largest single administrator of cap-and-invest funded programs. They recently approved a $1.5 billion low-carbon transportation investment plan (the largest to date), with $838 million from the general fund and $595 million from cap-and-invest. Active CARB programs include Community Planning and Capacity Building Grants ($7.3 million, individual awards up to $500,000) and over $200 million in clean freight transportation funding. The program has invested approximately $28 billion to date across 500,000+ individual projects. For energy sector organizations, this is the single most important state-level funding source in the country.
Housing: A New Agency and $2 Billion in Active Funding
California's housing funding system is being reorganized. The new California Housing and Homelessness Agency (CHHA) takes effect July 1, 2026, consolidating HCD, CalHFA, the Civil Rights Department, and the Interagency Council on Homelessness under one agency. How this affects application processes remains to be seen. Homekey+ has approximately $2.14 billion in Proposition 1 bond funds available: $1.033 billion for veteran-focused projects and $1.11 billion for all target populations. The original Homekey program has created nearly 16,000 homes across 250 projects, reaching over 172,000 Californians. Existing operating funds must be fully expended by June 30, 2026. A significant change for affordable housing developers: legislation signed in July 2025 reduced the bond financing threshold for 4% Low-Income Housing Tax Credit (LIHTC) projects from 50% to 25%. This means more projects can qualify for tax credits. The state has already awarded more than $2 billion in private-activity bonds to 108 affordable housing developments. No Place Like Home has $2 billion in bond proceeds for permanent supportive housing for people with mental health needs. HHAP Round 7 includes $500 million in the 2026-27 budget. A non-obvious cost factor: developing affordable housing in California costs over two times more than developing similar housing in Texas. The California Housing Partnership Corporation estimates the state could save $439 million per year by streamlining its funding system. Until that happens, developers need to plan for California-specific cost structures when building budgets.
Energy, Wildfire, and Environment
California Energy Commission has active solicitations with deadlines running through May 2026. GFO-25-606 (Fuels and Transportation, deadline May 7, 2026), GFO-25-304 (Energy Research and Development, deadline April 30, 2026), and others are currently accepting applications. The CEC is also developing its fifth EPIC investment plan covering 2026 through 2030, which will shape clean energy R&D funding for the next five years. CalFIRE wildfire prevention grants are active for FY 2025-26, funded through both cap-and-invest proceeds and Proposition 4 bonds. The Wildfire Resilience and Forestry Assistance Grant has up to $7 million available (minimum $1 million per grant). The Rural Fire Capacity Grant provides $500 to $20,000 with a 50% match requirement. After the January 2025 Los Angeles fires, which generated over $2 billion in federal disaster support and $2.5 billion in state recovery commitments, wildfire prevention funding has strong political support. Department of Water Resources is deploying Proposition 4 funds for dam safety and climate resilience ($231.5 million) and water quality ($183.2 million). The State Water Board's SAFER Program provides $130 million annually for safe drinking water, and the Water Recycling Funding Program has $625 million from Prop 1 plus $72 million from Prop 68. The Clean Water State Revolving Fund provides loans ranging from under $1 million to over $100 million. For organizations working in environmental funding, California's state programs are increasingly important as federal EPA funding contracts.
The Federal Funding Shift and California's Response
California is losing approximately $1.4 billion in federal funding in 2026-27. The OBBBA cuts over $900 billion from Medicaid nationally over 10 years, increasing California's Medi-Cal costs by roughly $1 billion. SNAP cuts total about $187 billion nationally, costing California $300 million in CalFresh funding. Up to 3.4 million Medi-Cal recipients could lose benefits. Medicaid work requirements begin December 31, 2026. California's response has two parts. First, litigation: the state spent $25 million on a litigation fund and reports restoring $168 billion in federal funding, a return of $33,600 for every dollar invested. The Attorney General has filed 37 lawsuits, with early victories in 17 of 19 cases seeking injunctive relief. This litigation buffering is unique to California and partially protects grant seekers in the state. Second, the state is shifting from federal dependency toward state-level mechanisms, particularly cap-and-invest funding, for climate, clean energy, and environmental programs. The Legislative Analyst's Office has recommended "re-engineering" how the state deploys resources given that federal grants are now less likely to be recoverable. This matters for California grant seekers because it means state programs are becoming more important relative to federal ones. Organizations that have historically focused on federal grants should be building capacity to apply for state programs through grants.ca.gov and agency-specific portals.
How to Apply: The Practical Reality
California's funding environment is complex. Some practical guidance. The grants.ca.gov portal is the centralized location for competitive and first-come state grants. But it is an information aggregator, not a universal application system. Each agency runs its own application process with its own formats and requirements. Checking grants.ca.gov tells you what exists. Actually applying requires going to each agency's portal. For state procurement, DGS (Department of General Services) runs CAL eProcure. State contracts have a 25% small business participation goal, and certifications (SB, DVBE, MBE, WBE) create real advantages. Apply through the DGS certification unit. For federal grants available to California organizations, register on SAM.gov and create a Grants.gov account. California hosts multiple DOE national laboratories, major DOD installations, and NASA JPL, creating concentrated federal contracting opportunities. The nonprofit reimbursement issue is worth planning for. If your organization depends on state grant reimbursements for cash flow, build a 90-day reserve or arrange a line of credit. Nearly 25% of nonprofits wait over three months. Over 50% cite burdensome reporting and complex applications as significant problems. About 60% say indirect cost funding is insufficient. California's fiscal year runs July 1 to June 30, different from the federal October to September cycle. The May Revise (the Governor's mid-year budget update) can affect spring funding availability. CEQA (California Environmental Quality Act) review can add 30 to 365 days for projects affecting the physical environment. Regional considerations matter. Northern California offers proximity to venture capital and tech talent but higher labor costs and strict permitting. Southern California provides aerospace and defense connections. Central Valley has lower costs but water scarcity drives agricultural sustainability requirements. Search California funding opportunities
