Pima County, AZ Home Business: Customer Traffic Restrictions (2026)

030(A). Subsection 12 sets the hard numeric limit: no more than five clients, including deliveries, in a single day, and never more than two clients on the property at the same time. That limit sits alongside a broader traffic and nuisance standard in subsection 8, which bars a home occupation from causing sustained unpleasant or unusual noise, vibration, fumes, odors, or traffic congestion in the immediate neighborhood. Parking gets its own rules too: under subsection 9, all customer and business parking has to stay on-site, and the property can't add commercial parking features like wheel stops, striped spaces or dedicated parking lanes, the sort of thing that would signal a commercial lot to the neighborhood.

Only one vehicle can be used in connection with the business, and it can't exceed eighteen feet in overall length or seven feet in height; if that vehicle carries any advertising or other sign of the business, it has to be kept in a garage or carport, or screened from the street and neighboring yards with landscaping or fencing. Child care and adult care home services, which by their nature see more daily traffic, get a separate carve-out under subsection B: they can serve up to ten people instead of five clients, but operators adding staff beyond the one employee allowed under subsection A must apply to the zoning inspector, notify property owners within three hundred feet, and clear a fifteen-day protest window before the board of adjustment if a neighbor objects.
