Summary
In unincorporated San Diego County, Section 72.230 of the County Traffic Code makes it unlawful to ride a bicycle on any sidewalk located within a business district. Once a cyclist is on the roadway instead, Section 72.233 subjects them to the same rights and duties as the driver of a motor vehicle. A first offense is an infraction, punishable by up to a $100 fine under the Code's general penalty schedule at Section 11.116(c).
SEC. 72.230. RIDING BICYCLES ON SIDEWALKS PROHIBITED. It shall be unlawful for any person to ride a bicycle upon any sidewalk in a business district. SEC. 72.233. TRAFFIC LAWS APPLY TO PERSONS RIDING BICYCLES. Every person riding a bicycle upon a roadway shall be granted all of the rights and shall be subject to all of the duties applicable to the driver of a vehicle established by this division... SEC. 72.50(a)-(c). Except as provided in subsection (b), any person performing any act forbidden or failing to perform any act required by this division shall be deemed guilty of an infraction. A person convicted of a third or subsequent violation of this division within two years from the date of the first conviction shall be deemed guilty of a misdemeanor. Each day on which a violation occurs or continues shall constitute a separate offense. SEC. 11.116(c). A conviction for all other infractions shall be punishable as follows: (1) A fine of not more than $100 for a first violation; (2) A fine of not more than $200 for a second violation ... within one year; (3) A fine of not more than $500 for the third and each additional violation ... within one year.

Full Breakdown
230 is narrow by its own text: it reaches only sidewalks "in a business district," a term this division does not define locally. 230 means looking to state law to decide whether a given commercial strip qualifies. Outside a business district, this section says nothing about sidewalk riding one way or the other; it neither authorizes nor forbids it, so no county-wide sidewalk cycling ban exists in the unincorporated area. 233 requires the rider to follow the same rules that bind motor-vehicle drivers under the County Traffic Code, and to receive the same rights, except for provisions that by their nature cannot apply to a bicycle.
Enforcement runs through the sheriff's traffic deputies who patrol county roads under this division. 50 sets the penalty structure for the whole Traffic Code, including this ban: a first or second violation is an infraction, but a third or subsequent conviction for violating this division within two years of the first conviction becomes a misdemeanor, and each day the violation continues counts as a separate offense. 116(c) controls: up to $100 for a first violation, up to $200 for a second violation of the same provision within a year, and up to $500 for a third or later violation within that year.
116(a) instead exposes a repeat rider to a fine of up to $1,000, up to six months in county jail, or both. This section governs only the county's unincorporated pockets; the 18 incorporated cities inside the county, including the City of San Diego, enforce their own bicycle and sidewalk codes.
Violations & Fines
A first sidewalk-riding citation in a business district is an infraction carrying a fine of up to $100 under Section 11.116(c)(1); a second citation within a year rises to up to $200, and a third or later citation within that year rises to up to $500. A third or subsequent Traffic Code conviction within two years becomes a misdemeanor under Section 72.50(b), exposing the rider to a fine of up to $1,000, up to six months in jail, or both. Each continuing day is a separate offense.
