Full Breakdown
40 (within Chapter 28, Zoning Regulations). The zoning code keeps a residential neighborhood looking residential, so on-site advertising is tightly limited. A Type I home occupation - the no-employee, no-customer category - is not designed to draw the public and does not include a customer-facing business sign. A Type II home occupation may display a single non-illuminated sign of modest size (on the order of two square feet) identifying the business. Window signs, illuminated signs, off-site signs, and anything that creates glare, traffic, or a commercial appearance inconsistent with the residential character of the area are not allowed under the home occupation rules.
Because the precise dimensions are fixed in Chapter 28 and the county updates the code periodically, confirm the current sign size and placement limits with Planning Services at 707-784-6765 when applying for the Business License Zoning Clearance.
Violations & Fines
Installing a sign larger than the home occupation rules allow, an illuminated sign, or any off-site sign violates the Chapter 28 standards and can be pursued as a zoning code-compliance case by Resource Management. The county can order removal of the non-compliant sign as a condition of keeping the home occupation in good standing.
