San Jose has marked a significant milestone by becoming the first city in California to approve the sale of an accessory dwelling unit as a condominium. This achievement opens new pathways for homeownership and addresses the pressing need for more housing options in the region. The inaugural unit at 410 Josefa Street, near Diridon Station, stands as a model for future developments, already occupied by tenants and ready for market.
The new ordinance allows accessory dwelling units, or ADUs, to be up to 1,200 square feet and 25 feet tall, regardless of attachment type. Rooftop decks are permitted with additional height allowances for safety railings.
