Summary
A home occupation in Santa Clara gets no dedicated business sign at all: Table 4-1 under Zoning Code Section 18.60.120 states no signs are allowed except whatever a dwelling unit could display anyway under Chapter 18.42 (Sign Standards). That leaves only exempt residential signage, since the residential sign table sets no permit category for home-business advertising.
No signs are allowed except for signs allowed for a dwelling unit in compliance with Chapter 18.42 (Sign Standards).
Full Breakdown
120 (Home Occupations) lets residents run a business from a Santa Clara dwelling only after the Community Development Department issues a Zoning Clearance confirming the operation meets every standard listed in Table 4-1 (Home Occupation Standards). 42 (Sign Standards). 42, such as an exempt house-number name plate. ; the business confined entirely inside the dwelling, capped at 25 percent of the floor area and barred from the garage or yard; access only from inside the dwelling with no separate exterior entrance; and no more than one commercial vehicle under 8,000 pounds gross weight kept on the property.
A Business Tax Certificate does not substitute for the required Zoning Clearance, and the Department can deny or revoke authorization if the sign standard, or any other Table 4-1 requirement, is violated.
Violations & Fines
Operating a home occupation without the Zoning Clearance required by Section 18.60.120, or violating any Table 4-1 standard including the ban on dedicated business signage, means the home occupation was never authorized in the first place; holding a City Business Tax Certificate does not cure the defect. A sign posted in violation of the Table 4-1 signage limit is also unlawful under the general Sign Standards applicability clause, Section 18.42.010(B), and can be ordered removed under Section 18.42.190.
