Mandates local approval of accessory dwelling units.

Local governments must adopt ordinances allowing accessory dwelling units in single-family zones by December 1, 2026. This replaces the previous optional authority with a mandatory requirement.

Ordinances must allow approval by right, prohibiting discretionary hearings, owner-occupancy mandates, and increased parking requirements. This streamlines the construction process for new units.
