Hesperia FAQ
Can I cut down a Joshua tree on my Hesperia property?
No, not without a permit. Under the Western Joshua Tree Conservation Act (Cal. Fish & Game Code §1927) and Hesperia Municipal Code §16.24.110, you must obtain a take permit from CDFW and may need to pay a mitigation fee before removing, relocating, or trimming a Western Joshua tree.
Do I need a permit to trim trees on my own property in Hesperia?
For non-protected trees on private property, routine pruning is generally unregulated. But Joshua trees and other protected desert plants require approval, and any tree in the public right-of-way requires a city permit before trimming.
San Bernardino FAQ
Do I have to trim branches hanging over the sidewalk?
Yes. The owner must maintain at least 8 ft of clearance over sidewalks and 14 ft over the travel lane; the city can cite you if branches obstruct pedestrians or signs.
How high must I limb trees in the foothills?
California PRC 4291 requires the lowest limbs to be pruned 6 ft above the ground, canopies separated 10 ft apart, and no branches within 10 ft of chimneys.
Can I cut my neighbor tree branches that cross my property line?
California case law allows a neighbor to trim to the property line at their own cost, but you may not damage the tree health or enter neighbor property without consent.
