San Jose FAQ
Can I cut a tree of heaven myself without a permit?
Likely yes for trees on private property below San Jose's protected-tree threshold under SJMC Chapter 13.32. Confirm trunk diameter rules first, since larger specimens may still need a tree-removal permit.
Should I report a suspected spotted lanternfly sighting?
Yes. Photograph the insect, note the location, and report immediately to the Santa Clara County Agricultural Commissioner or CDFA Pest Hotline. Early detection is critical for California's quarantine response.
Sunnyvale FAQ
How do I report a tree of heaven sighting in Santa Clara County?
Call the Department of Agriculture and Environmental Management pest hotline or use the CDFA Report-A-Pest portal. Photographs of compound leaves and a precise location help inspectors verify the species and check for lanternfly egg masses.
Am I required to remove tree of heaven from my yard?
Not under current Santa Clara County rules unless a state quarantine is declared. Voluntary removal is strongly encouraged, especially near waterways managed by Valley Water, because the species displaces native riparian vegetation.
