AB-1033 Complete Guide 2025: Everything Property Owners Need to Know

What is AB-1033 and Why It Matters

Assembly Bill 1033, signed into law in California, represents a groundbreaking shift in accessory dwelling unit (ADU) regulations. For the first time in California history, property owners can now sell their ADUs as separate condominium units, independent from the primary residence.

Key Benefits of AB-1033

  • Increased Property Value: Convert your ADU into a sellable asset that can generate significant returns
  • Flexible Ownership: Sell the ADU while keeping your primary residence
  • Investment Opportunities: Create new revenue streams through separate property ownership
  • Housing Solutions: Address California's housing crisis by increasing affordable homeownership opportunities

Eligibility Requirements

Not all ADUs qualify for AB-1033 conversion. Your property must meet specific criteria:

Property Requirements

  • Located in a participating AB-1033 city or county
  • ADU must be legally constructed with proper permits
  • Property must be zoned for residential use
  • Compliance with local building codes and safety standards
  • Adequate parking and utility access

Legal Compliance

  • All construction permits must be finalized and approved
  • Property taxes must be current
  • No outstanding code violations
