Frequently Asked Question
Is my property eligible for AB1033 conversion?
Eligibility depends on whether your local city has adopted AB 1033 ordinances allowing separate condominium conversion of ADUs, and whether your ADU is properly permitted, meets fire/safety requirements, and has clear title without lender restrictions. Many major California cities like San Jose support this.
Do I need my lender's permission to convert?
Yes — if your property has a mortgage, lenders must provide written consent for any condominium subdivision or sale. Without this, the conversion may not be approved.
How long does the entire legal process take?
The process timing varies by city and complexity, but navigating the AB 1033 conversion — including feasibility checks, parcel mapping, inspections, and approvals — typically takes several months. It depends on local permitting and submission timing.
What are the total costs involved in conversion?
Conversion costs vary widely based on property and city requirements, but typical expenses include surveying, legal fees, inspections, utility coordination, and recording fees. Combined, these can range from tens of thousands of dollars depending on complexity
Can I sell the ADU separately while living in the main house?
Yes — AB 1033 allows separate sale of the ADU as its own condominium unit, while you can retain and continue to live in the main house, if local ordinances permit it and the legal subdivision is completed.
Will my property taxes increase significantly?
When an ADU is converted to a separate condominium, property tax reassessment or increased premiums are possible because the units become individually titled. The exact impact varies by jurisdiction.
