Rohnert Park FAQ
Can I hire an assistant to work at my home business?
No. Sonoma County Code § 26-88-121 states 'no person shall be employed in the home occupation other than residents' of the dwelling. To employ non-residents at home you would need to qualify as a Live/Work use, which has stricter zoning requirements.
Can clients come to my home outside business hours?
No. Customer visits and deliveries are limited to 8 a.m. to 6 p.m. Monday through Friday, excluding state and federal holidays. Evening and weekend customer traffic is prohibited under § 26-88-121.
What home businesses are flat-out prohibited?
Sonoma County prohibits animal hospitals, kennels, doggie day cares, pet grooming, automotive repair, food processing, hair salons, medical procedures, welding, and any use the director finds 'similar in impact.' These need a separate use permit in a commercial zone.
Sonoma FAQ
Can I run my home business out of my detached garage or backyard studio in Sonoma?
No. SMC §19.50.040(B) requires the home occupation to be confined completely to the residential dwelling unit. Accessory structures such as garages, sheds, ADUs used as workspace, and backyard studios cannot be used for the home occupation.
Do I need a permit just for a laptop-only consulting business with no clients visiting?
Yes. SMC §19.50.040 requires a City business license and a home occupation permit (typically an Administrative Permit) for any business operated from a residence, even office-only uses with no client visits.
What happens to the permit if I move or sell the house?
The permit is deemed void. Per §19.50.040, any change in ownership or tenancy from that shown on the approved application terminates the home occupation permit, and the new occupant must apply for their own.
