Sunnyvale, CA Home Business: Customer Traffic Restrictions (2026)

010 conditions every home occupation on a business license and director of community development sign-off that the use meets fourteen listed restrictions. Subsection (j) caps total daily vehicle visits, customers, vendors and delivery services combined, at three per day, and separately bars any vehicular traffic generated by the business from interfering with normal residential traffic circulation on the street. That cap sits alongside related restrictions that shape how much foot and vehicle traffic a home business can realistically draw: subsection (e) bars anyone but residents of the dwelling from working or reporting to work on the premises, subsection (i) prohibits selling any merchandise, product or tangible thing on-site, and subsection (g) requires all advertising to state 'by appointment only' when the home address is used, which discourages walk-in visits.

Subsection (k) additionally bars external noise, odor, glare, vibration or electrical interference detectable by adjacent neighbors, a standard that in practice limits how much delivery or client activity a home occupation can generate without breaching the traffic cap. The business is capped at 20 percent of the dwelling's floor area or 400 square feet, whichever is less (subsection d), and storage of inventory is capped at 50 cubic feet (subsection h), further constraining the scale of any customer-facing operation. Sunnyvale places no limit on how many home occupations run out of one address, but subsection (n) makes clear that the cumulative traffic, noise and other impacts of all businesses combined cannot exceed the limits set for a single home occupation.
