How do heritage & protected trees rules compare between Chino, CA and Ontario, CA?
Chino has fewer restrictions than Ontario.
Chino, CA
San Bernardino County
Chino does NOT have a heritage tree ordinance. There is no city-maintained list of heritage trees, no DBH (diameter at breast height) threshold for protection, and no special permit required to remove a large or historically significant tree on private property. This is markedly different from neighboring Chino Hills, which protects any tree 44 inches DBH or greater under CHMC Ch. 16.90 — a Chino Hills rule that does not extend into Chino city limits.

Chino FAQ
Does Chino have a heritage tree list?
No. Chino has no heritage tree ordinance, no protected-tree registry, and no diameter threshold for special permitting on private property.
I read that you cannot cut a 44-inch tree in Chino — is that true?
That rule is from Chino Hills (CHMC Ch. 16.90), a separate city. It does not apply within the City of Chino limits.
Are any trees protected at all?
Trees on public right-of-way and trees required by a development approval/landscape plan are protected through Public Works and Community Development. Mature oaks affected by a new development can also trigger California's Oak Woodlands Conservation Act review.
Ontario FAQ
Does California require permits to cut a backyard oak?
Not at the state level for individual residential trees. CEQA oak review applies to discretionary development projects, not routine private removals, though many cities require permits.
What counts as oak woodland under PRC 21083.4?
An oak stand with greater than 10% canopy cover that includes one or more native oak species, as defined by the statute.
