What is Condominium Conversion in San Jose?

In California, a condominium conversion—also known as a condo conversion—is the legal process of converting a property that has multiple units under a single title (for example, a primary residence with one or more accessory dwelling units) into individually owned condominium units with shared common areas.

ADU Condominium Conversion in San José

Since June 2024, San José has been the first city in California to allow the sale of accessory dwelling units (ADUs) as separate condominiums.
This means that if you have a legal, permitted ADU, you may convert it into a standalone condominium unit—completely separate from your primary residence. Once the ADU is individually ownable and conveyable, it can be sold as its own unit, with a separate address, property tax bill, and title—just like a traditional condominium.
Previously, an ADU could only be sold separately from the main residence in very limited circumstances (such as if it was developed by a qualified nonprofit).
For more detailed information or specific guidance, we can book a free consultation with an Apex Home ADU expert.
