  • •If city doesn't adopt ordinance by Jan 1, 2026, ADUs allowed 'without restriction'
  • •Expedited review and appeal process required
  • •Local control over specific design standards

📖Detailed Analysis

AB 396 (2025) requires qualifying large cities to adopt ADU ordinances by Jan 1, 2026 or ADUs become allowed without restriction. Reno adopted ordinance Oct 8, 2025 allowing ADUs citywide on lots 5,000+ sqft with parking and size/height subordination to primary dwelling. Las Vegas status unclear. State takes middle approach - mandates local authorization but preserves significant local control over standards.
