Question 1

Do I need a tree permit for a home remodel in the Bay Area?

Accepted Answer

If any protected tree is within the construction zone or its root zone could be affected by excavation, grading, or heavy equipment, most Bay Area cities require an arborist report and tree protection plan as part of your building permit. Trees are considered protected above a certain diameter threshold that varies by city, from roughly 6 inches in Campbell to 18 inches in cities like Saratoga and Milpitas.

Question 2

What is a tree protection zone for construction?

Accepted Answer

The tree protection zone or TPZ is typically defined as the area within the drip line of the tree, or a radius equal to one foot per inch of trunk diameter, whichever is greater. No excavation, grading, material storage, or vehicle traffic is allowed within the TPZ without an arborist's approval. Violating the TPZ can result in stop-work orders and fines.

Question 3

Can a tree delay my construction project?

Accepted Answer

Yes. If a protected tree is damaged during construction without a tree protection plan, cities can issue stop-work orders that halt your entire project. In cities like Saratoga, penalties for damaging a protected tree can reach three times the appraised value, potentially exceeding $100,000. Getting an arborist report before submitting building permits can prevent these delays.
