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.
Ontario FAQ
Can I trim the city tree in front of my house?
No. Parkway street trees are city property. You must request trimming through Ontario Public Works or obtain a permit before any work.
Can I cut my neighbor's branches that hang over my yard?
Yes, up to the property line under California common law, but only if you do not harm the tree's overall health.
