CA SB4

Requires housing developments on land owned by independent institutions of higher education or religious institutions (owned before January 1, 2024) to be approved as a "use by right" upon request, bypassing conditional use permits and discretionary local review.

Mandates 100% of units be affordable to lower-income households (with up to 20% for moderate-income and 5% for institutional staff), with rents set according to California Tax Credit Allocation Committee limits, and deed restrictions of 55 years for rental or 45 years for owner-occupied units.

Prohibits parking requirements if development is within one-half mile of public transit or one block of a car share vehicle; otherwise limits parking to one space per unit unless state law or local ordinance provides lower standards.

Requires local governments to provide written documentation within 60-90 days (depending on unit count) if they determine development conflicts with objective planning standards; development is deemed compliant if local government fails to provide timely documentation.

Applies prevailing wage requirements and health care expenditure standards for construction workers; expires January 1, 2036.
