Final Plan Bay Area 2050+
Plan Bay Area 2050+ is the latest long-range plan to guide growth and investment across the region’s nine counties and 101 cities. The plan seeks to advance an integrated vision for a Bay Area that is affordable, connected, diverse, healthy and vibrant for all by 2050.
After nearly three years of public discussion, technical analysis and refinement, Plan Bay Area 2050+ was adopted by the Association of Bay Area Governments (ABAG) on March 19, 2026, followed by the Metropolitan Transportation Commission (MTC) on March 25, 2026.
Plan Bay Area 2050+ contains 35 strategies representing public policies and investments that can be implemented in the Bay Area by 2050 to help the region build more homes, reduce commute times and create vibrant downtowns and natural areas for everyone to enjoy. The plan’s strategies also aim to keep people safe from natural hazards, support a strong economy and provide stable housing for those who need it most.
Unique to this plan cycle was the parallel Transit 2050+ planning effort, which culminated in the first-of-its-kind plan to re-envision the future of Bay Area public transit, in partnership with transit agencies across the region.
