Fence Installation Permits in Rancho Cucamonga
Local Rule
City of Rancho Cucamonga Building and Safety Services
Rancho Cucamonga exempts wood, chain-link, plastic, metal, or similar fences up to 6 feet, and masonry or concrete fences up to 3 feet above the lowest adjacent grade, from a building permit. Separately, under Development Code Chapter 17.48, new fences and walls generally require Site Development Review (a planning entitlement) unless specifically exempt, so a fence can be exempt from the building permit but still need planning approval. Fence height is measured from finish grade at the base to the uppermost point, except where ground level differs between adjoining parcels, in which case special measurement rules apply. Retaining walls under 36 inches are exempt from Chapter 17.48 except for terraced walls required under the Hillside Development standards. Perimeter fencing and gated communities are prohibited in form-based zones, excluding required screening.

How This Compares to San Bernardino County
Rancho Cucamonga's own rule is shown above (No permit under 6 sqft). Here is the separate rule that applies at the county level, for context:
City/County zoning
In San Bernardino County, California's fence rules apply: a fence over 6 feet in the rear or side yard, or over about 3.5 feet in the front yard, typically needs a permit, and in CAL FIRE-mapped fire-hazard zones the fence must use non-combustible materials. California's Good Neighbor Fence Law (Civil Code 841) presumes neighbors share the cost of a boundary fence, and pool barriers must be at least 60 inches with two safety features. Incorporated cities may set their own limits.
