California Pro-Housing Groups Split Over Proposition 45 Environmental Reforms

A statewide ballot measure to streamline environmental reviews under the California Environmental Quality Act has divided housing advocacy and urban planning organizations across the state. Sponsored by the California Chamber of Commerce, Proposition 45 aims to establish strict deadlines for public agency environmental reviews, narrow litigation remedies, and accelerate approvals for housing, energy, water, and transportation infrastructure.

Supporters argue the reforms are essential to lower living costs and eliminate procedural delays that hinder necessary infrastructure and home construction. Several organizations, including the California Council for Affordable Housing, have backed the measure.

However, other housing groups have withheld support or opposed the initiative. East Bay for Everyone announced its opposition, stating that state legislation passed in 2025 already provided CEQA relief for infill housing and arguing Proposition 45 primarily eases the path for car-dependent outward sprawl. California YIMBY adopted a neutral stance, noting valid arguments on both sides while raising concerns regarding development in wildfire-prone areas. SPUR also declined to take a position, citing mixed outcomes regarding positive infill streamlining versus potential environmental risks.
