The existence of a home occupation shall not be apparent beyond the boundaries of the site, and no home occupation shall involve the use of a sign.

Full Breakdown
220(C)(4), part of the Home Occupation in R Districts standards, sets a strict no-signage rule: the existence of a home occupation shall not be apparent beyond the boundaries of the site, and no home occupation shall involve the use of a sign. That covers yard signs, window signs, and any other on-site signage identifying the business, not just off-site advertising. 9 bars any advertising, including business cards, from listing the home's address. Together, these rules mean a San Leandro home business cannot use exterior signage, address-bearing print advertising, or a visibly marked vehicle to announce its presence in a residential neighborhood.

Violations & Fines
Installing any sign for a home occupation, or otherwise making the business apparent from outside the property line, violates Section 2.04.220(C)(4). The Zoning Enforcement Official can revoke the home occupation permit after 30 days' written notice if the sign is not removed, and continued noncompliance is also enforceable as a zoning violation under Section 5.24.112, escalating to a misdemeanor with a fine up to $1,000 or up to a year in jail.
