San Jose
Status: Active
Ordinance: 31095
San Jose was the first major California city to activate AB 1033 and allow certain detached ADUs to be converted into separate condominium units. That means separate ownership and potential separate sale is no longer just theoretical here. It’s a real pathway, as long as the property meets the city’s requirements.
Key Highlights
First Major City to Implement AB 1033
San Jose was among the first large California cities to adopt a local ordinance enabling detached ADUs to be sold as separate condominium units.
First ADU Condo Sale Completed
San Jose has already approved and completed the first detached ADU condominium sale, proving the pathway is active and operational.
A Real Pathway to Sell Your ADU
Homeowners may qualify to convert and sell a detached ADU, subject to mapping, separation, and compliance requirements.
San Jose Is Leading California’s ADU Condo Movement
San Jose isn’t just allowing accessory dwelling units — it’s redefining what they can become. Under Assembly Bill 1033, the city adopted one of California’s earliest local ordinances allowing detached ADUs to be converted into separate condominium units. For homeowners asking, “Can I sell my ADU in San Jose?” the answer is no longer a flat no. It may be possible.
San Jose has already approved and completed the first detached ADU condominium sale. That milestone matters. It signals that this isn’t theoretical policy — it’s an active pathway. For homeowners who have invested in a backyard unit, ADU condo conversion could represent a way to unlock equity, create flexible ownership structures, or sell a detached ADU legally as its own property.
Of course, it’s not automatic. Converting an ADU to a condominium requires compliance with the city’s ordinance, including mapping requirements, utility separation standards, and documentation that clearly defines unit boundaries. But San Jose has demonstrated that when those requirements are met, separate ADU ownership can move from possibility to reality.
In one of the most competitive housing markets in the country, the ability to create smaller, more attainable ownership opportunities may reshape how backyard homes function in the broader housing ecosystem.
