California Code, Health and Safety Code - HSC § 101325

Whenever the governing body of any city or county determines that the expenses of the local health officer or other officers or employees in the enforcement of any statute, order, quarantine, or regulation prescribed by a state officer or department relating to public health, requires or authorizes its health officer or other officers or employees to perform specified acts that are not met by fees prescribed by the state, the governing body may adopt an ordinance or resolution prescribing fees to pay the reasonable expenses of the health officer or other officers or employees incurred in the enforcement, and may authorize a direct assessment against the real property in cases where the real property is owned by the operator of a business and the property is the subject of the enforcement. The schedule of fees prescribed by ordinance or resolution of the governing body shall be applicable in the area in which the local health officer or other officers or employees enforce any statute, order, quarantine, or regulation prescribed by a state officer or department relating to public health.
