What AB 1033 Means for Homeowners, Buyers, and Communities?

California’s housing landscape just changed in a big way. With the passage of AB 1033, homeowners and communities now have access to an innovative housing solution: ADU condominium conversions. For the first time in state history, an Accessory Dwelling Unit (ADU) can be sold separately from its main residence, unlocking new opportunities for ownership, investment, and affordability.

 

For Homeowners:

AB 1033 empowers homeowners to maximize their property’s potential. By building an ADU and converting it into its own condominium unit, owners can create a new asset that can be sold, rented, or passed down. This means homeowners can unlock equity, generate revenue, and increase the overall value of their property, without having to sell their primary home. For families, it’s a chance to pass wealth on to the next generation. For investors, it’s a way to diversify their portfolio with an entirely new class of housing.

 

For Buyers:

The law opens the door for buyers who have been priced out of California’s competitive housing market. Instead of purchasing an entire home, buyers can now purchase a more affordable ADU condominium. This creates a new pathway to entry-level homeownership, allowing families and individuals to build equity and stability at a more attainable price point. In cities like San Jose, where single-family homes can exceed $1M, ADU condos may be priced hundreds of thousands lower, putting ownership back within reach.

 

For Communities:

AB 1033 has the potential to reshape neighborhoods across California. By enabling ADUs to be sold separately, cities can increase housing supply, diversify housing options, and create stronger, more inclusive communities. This approach helps address the state’s housing shortage while keeping homeownership within reach for more families. It’s not just about numbers; it’s about giving people the chance to stay rooted in their communities while welcoming new homeowners at attainable price points.

 

The Future of AB 1033

San Jose was the first city in California to adopt AB 1033, setting a bold precedent for other municipalities to follow. In August 2025, AlphaX RE Capital completed the state’s first-ever ADU condominium conversion, paving the way for others. Over the next year, AlphaX plans to deliver 86 more ADU condominiums, expanding affordable homeownership opportunities across the state.

As more cities adopt AB 1033, the impact will grow—helping homeowners unlock equity, giving buyers new paths to ownership, and helping communities meet housing needs in sustainable, innovative ways. With pioneers leading the charge, the future of housing in California is becoming more flexible, attainable, and community-focused. One backyard at a time.
