City of San Diego Municipal Code Section 31.0121 states that no person shall engage in any business, trade calling, or occupation until a certificate of payment is obtained. Self-employed persons and independent contractors are also required to pay the Business Tax.
Issuance of the certificate does not authorize the conduct of any illegal or unlawful business or any business activity for which a license or permit is required by state law, county ordinance or the San Diego Municipal Code, including but not limited to police, health, zoning, planning, building or engineering permits, or state contractors licenses and the like. The issuance of a Business Tax Certificate shall not relieve an owner or operator from obtaining any licenses or permits that may be necessary under other provisions of law for employees or for operation of the business.
Businesses will be required to self-certify that the business is allowed in the zone that applies to the property where the business activity will be conducted. Businesses may use the following on-line resources to perform self-certification:
