Summary
Cupertino permits home occupations in residential zones only when the business stays clearly incidental and secondary to residential use and does not change the home's residential character. Municipal Code Section 19.120.020 requires a City business license tax certificate before starting, and Section 19.120.050 bans a list of occupations outright.
Home occupations conducted in accordance with the provisions of this chapter shall be permitted in residential zones, and in other areas where residential use is allowed, provided that the occupation is clearly incidental and secondary to the use of the dwelling for residential purposes, and does not change the residential character thereof; and provided that such occupation is not detrimental to the health, safety, public welfare and property values in the neighborhood. Authorization to establish a home occupation shall be evidenced by payment of a business tax and the issuance of a City of Cupertino business license tax certificate.
Full Breakdown
010, to let residents work from home while protecting neighborhoods from the effects of that activity. 020 sets the general test: a home occupation is allowed in residential zones and in other areas where residential use is allowed only if it is clearly incidental and secondary to the dwelling's residential purpose, does not change the residential character of the property, and is not detrimental to health, safety, public welfare or neighborhood property values. Before opening, the operator must pay a business tax and obtain a City of Cupertino business license tax certificate, and the business stays subject to all Municipal Code provisions governing business licenses.

Violations & Fines
The Director of Community Development enforces the operating standards in Table 19.120.030 on a continuing basis, not just at start-up, so a home business that later exceeds those limits, or turns out to be an excluded occupation under Section 19.120.050 such as an auto repair shop or a medical office, loses its home-occupation status and can have its business license tax certificate revoked.
