CA AB2552

Establishes that contributions to the Transit-Oriented Development Implementation Fund constitute "full and complete mitigation" for a project's significant transportation impacts under CEQA, providing legal certainty for developers

Allows lead agencies to mitigate vehicle miles traveled (VMT) impacts by funding affordable housing or infrastructure projects in location-efficient areas, with priority given to projects within the same region

Requires the Office of Land Use and Climate Innovation to issue implementation guidance by July 1, 2026, including methodology for calculating required contribution amounts and validating VMT reduction estimates

Declares the Legislature's intent to prevent project-by-project litigation challenging the mitigation framework, stating such challenges "undermine CEQA's efficiency and predictability" and delay beneficial projects

Takes effect immediately as an urgency statute to align with the July 1, 2026 deadline for the Office of Land Use and Climate Innovation to issue VMT mitigation guidance
