California note
An Irvine business license does not replace the zoning check
Irvine's license is a city tax registration. The application also requires the applicant to review the address, confirm the zoning fit, and describe one exact business activity.
An Irvine business license is a city tax registration. It does not mean that every kind of business is allowed at the address. On the form, you must review the zoning and certify that the business fits the site.
Two rules show why the address check matters. An office cannot be the main use in zones 5.4 and 5.4A. Some uses in the 5.1 Irvine Business Complex need a conditional use permit. Medical offices and restaurants are two examples. Call Planning at 949-724-6308 when the fit is not clear.
A home business has added limits. The home cannot be the main place for customer pickup, delivery, or services. Exterior signs and direct sales are not allowed. Only people who live there may work at the home; other employees must work somewhere else.
For a new license, have the business address, mailing address, start date, and owner details. Name one exact business activity on each form. A renewal uses the current license number and security code.
