Before You Remove a Tree in Ventura County: Permits, Protected Trees, and Other Rules
Taking down a tree on your own property seems like it should be your decision alone, and often it is. But in Ventura County, several layers of rules can apply: city or county tree ordinances, protections for native oaks, street tree rules, laws protecting nesting birds, HOA covenants, and utility safety requirements. This guide walks through what to check before scheduling a removal. It’s general information, not legal advice, and rules change, so confirm with the relevant agency.
1. Is the tree protected by your city or the county?
Several Ventura County jurisdictions regulate the removal of certain trees on private property. Native oaks are the most commonly protected, but other species, very large trees, or trees designated as historical or heritage trees can also be covered.
- Incorporated cities (Ventura, Oxnard, Thousand Oaks, Simi Valley, Camarillo, Moorpark, Ojai, Santa Paula, Fillmore, and Port Hueneme) each set their own rules. Thousand Oaks is especially well known for protecting native oaks.
- Unincorporated areas (such as Somis, Santa Rosa Valley, Oak Park, Oak View, and much of the county’s rural land) follow the County of Ventura’s rules, which include protections for certain native trees.
- Newbury Park and the Ventura County side of Westlake Village are part of the City of Thousand Oaks, so the city’s rules apply. (The separately incorporated City of Westlake Village sits across the line in Los Angeles County and has its own rules.)
What to do: Call or check the website of your city’s planning or community development department, or the County of Ventura’s planning division for unincorporated areas. Ask whether the tree is regulated and what’s required. For protected trees, you may need an arborist report, a permit application, and replacement planting.
Protected-tree rules can also apply to pruning above a certain amount, construction or grading near a tree (within the root zone), and even dead trees. Don’t assume a dead or hazardous tree is exempt without asking.
2. Is it a street tree?
The strip between the sidewalk and the street (the parkway) often belongs to the city, along with the trees in it. Many Ventura County cities maintain their own street trees. Removing or heavily pruning a city tree without permission can bring fines. Contact your city’s public works or urban forestry program.
3. Are there active bird nests?
Federal and California laws protect most native birds and their active nests. Spring and summer are peak nesting season. Reputable tree services check for nests before cutting and may delay non-emergency removal if they find an active nest. Hawks and owls also nest in large trees here. Planning removals outside of nesting season when possible avoids delays.
4. What does your HOA say?
Many planned communities in Camarillo, Moorpark, Thousand Oaks, Westlake Village, Simi Valley, and Oxnard have covenants governing trees, especially in front yards. Some HOAs are responsible for certain trees. Removing a tree without required approval can lead to fines or replacement requirements. Read your CC&Rs and submit a request if needed.
5. Is the tree near power lines?
If a tree is near overhead utility lines, contact SCE. Utility crews or qualified line-clearance workers handle vegetation near energized lines. Never try to prune or remove trees touching power lines yourself.
6. Is the tree on a property line?
In California, a tree whose trunk stands on a boundary line can be jointly owned by both neighbors. Removing a shared tree without agreement can lead to disputes or liability. Talk with your neighbor, and put agreements in writing.
7. Wildfire and defensible space
In fire hazard areas, fire officials may require or recommend removing or thinning vegetation near homes. Defensible-space requirements and tree protections can overlap. If you receive a notice from the fire department to clear vegetation, and a protected tree is involved, ask both the fire department and your city or county how to comply with both. Often, pruning, removing dead material, and separating canopies from structures can satisfy fire guidance without removing a protected tree.
8. Underground utilities
If the job includes stump grinding or digging, the contractor should contact DigAlert (811) to have public underground utilities marked. Point out private lines like irrigation and landscape lighting.
A simple pre-removal checklist
- Identify the species and measure the trunk (a tree service or arborist can help).
- Check with your city or the County of Ventura about protected-tree rules.
- Confirm whether it’s a city street tree.
- Check HOA rules.
- Plan around nesting season when possible.
- Call SCE if lines are nearby.
- Talk to neighbors about shared or boundary trees.
- Hire a licensed, insured tree service and get a written scope that includes cleanup and stump work.

Frequently asked questions
Can I remove a dead oak without a permit?
Don't assume so. Some ordinances still require notification or a permit for dead or hazardous protected trees. Check with your city or the county first.
What if a protected tree is an immediate hazard?
Many ordinances have provisions for emergencies, but you may need to document the hazard and notify the city or county. Ask before acting unless there's immediate danger.
