AB 1033 in Orange County: Selling Your ADU Separately in Anaheim, Santa Ana, Irvine & More

Orange County: A Massive Opportunity for ADU Condo Sales

Orange County is one of the most expensive housing markets in California. The median home price hovers around $1 million, making homeownership a distant dream for many working families. AB 1033 could change that by creating a new class of affordable condo units — converted from ADUs built in backyards across the county.

Building an AB 1033-Ready ADU in Orange County

OC-Specific Design Considerations

Orange County buyers tend to value:

Outdoor living space — OC's climate makes patios and outdoor areas a premium feature
Parking — Critical in suburban OC neighborhoods; dedicated parking adds significant value
Modern California aesthetic — Clean lines, natural light, indoor-outdoor flow
Energy efficiency — Solar panels, dual-pane windows, proper insulation (also reduces utility costs for the eventual condo owner)
Quality finishes — OC buyers expect a higher level of finish than some other markets

The Vision ADU Approach in Orange County

Our team has worked with homeowners across Orange County, including:

Santa Ana — Multiple garage conversions and new construction ADUs
Anaheim — New construction ADUs and JADUs
Whittier — Garage conversions with premium finishes (border of LA/OC)

Every unit is built to AB 1033 standards: separate entrance, independent utilities, premium finishes, and full permits.
