Alameda homeowners will soon have a new option for their accessory dwelling units — and it could change how you think about building one.
What is AB 1033?
Assembly Bill 1033 is a California state law that allows local jurisdictions to permit ADUs to be sold separately from the primary residence, essentially converting them into condominiums. For years, ADUs in California could only be built as rental units or kept as part of the same property title as the main house. With new policies like AB 1033, it’s reasonable to ask: is it time you change how you think about your ADU? AB 1033 changes that — but only in cities that formally opt in with their own local ordinance.
The City of Alameda is now moving toward becoming one of those cities.
The June 22, 2026 Planning Board Meeting
On June 22, Alameda’s Planning Board advanced a proposal that would implement AB 1033 locally, unanimously recommending updates to the City’s Accessory Dwelling Unit ordinance to allow ADU-to-condominium conversions. The draft resolution followed an earlier study session, after which city staff drafted a new process that would permit these conversions. With all these changes, some may wonder: is it time to change how you think about your ADU under the emerging rules? Alameda Post
Support for the change has been building for a while. Back in May, the Planning Board had already signaled broad support for allowing ADUs to be converted into condominiums and sold separately, with board members arguing the policy would expand housing flexibility and create additional pathways to homeownership while posing limited risk to the city’s rental housing stock. Advocacy groups including the Casita Coalition and California Housing Defense Fund have also weighed in, arguing that allowing ADU ownership would expand housing options and create new pathways to homeownership. That leads to the important question: is it time to change how you think about your ADU in Alameda, given these new possibilities?
What This Means for Alameda Homeowners
When the City of Alameda formally adopts an AB 1033 ordinance, homeowners will be able to build an ADU with the intention of eventually selling it as its own condominium unit — separate from the main house. That opens up possibilities that didn’t exist before, and you might be wondering, is it time to change how you think about your ADU strategy?
- A path to homeownership for a family member, adult child, or first-time buyer, without subdividing the lot.
- A new equity tool for homeowners who want to build now and have the flexibility to sell later.
- A smarter long-term investment, since a condo-eligible ADU can appeal to a broader range of future buyers than a rental-only unit.
Of course, converting an ADU to a condo isn’t as simple as flipping a switch. It typically involves preparing a condominium plan, meeting Davis-Stirling Common Interest Development requirements, forming a homeowners’ association for shared spaces and exteriors, and notifying utilities of the new, separately owned unit. Getting the ADU’s design and site plan right from day one makes all of that dramatically easier down the road. Ultimately, this all circles back to one essential question: is it time to change how you think about your ADU, especially with so many opportunities opening up?
Why This Matters for How You Build Your ADU Today
This is where design and construction experience really matter. An ADU that’s built with future condo conversion in mind needs thoughtful separation of utilities, clear boundary lines, durable shared infrastructure, and layouts that hold up to condominium-plan requirements. Now more than ever, is it time to change how you think about your ADU design and construction choices?
At Alameda Tiny Homes, we’ve spent years building ADUs specifically in Alameda. That local focus matters. We know the city’s permitting process, its Planning Board priorities, its lot patterns, and its building department inside and out. As Alameda moves to formally adopt its AB 1033 ordinance, our designs are already well-suited to this new conversion pathway, because we’ve always built ADUs with quality, durability, and long-term flexibility in mind. In light of these changes, it’s worth asking yourself: Is it time to change how you think about your ADU for the future?
