read moreRohnert Park is one of California's few master-planned cities, originally developed in the 1950s by developer Paul Golis. This unique urban layout, characterized by its distinctive neighborhood circles and uniform residential streets, presents specific considerations for ADU contractors in Rohnert Park. The city's structured design means that lot sizes, setbacks, and neighborhood aesthetics play a significant role in how Accessory Dwelling Units are planned and constructed throughout the community.
ADU contractors working in Rohnert Park must navigate both California state ADU laws and the city's local ordinances. Under California law (AB 68, AB 881, and SB 13), homeowners have broad rights to build ADUs, and Rohnert Park has aligned its local codes accordingly. Key regulations that experienced Rohnert Park ADU builders must be familiar with include:
