Tree Removal Permit Guide

Tree Removal Permits in San Luis Obispo: A Homeowner’s Guide

San Luis Obispo has some of the strictest tree removal laws on the Central Coast, designed to protect heritage oaks and other native species that define the city’s landscape. If you live in San Luis Obispo city limits and need to remove a tree, chances are you’ll need a tree removal permit. Cutting without approval can result in fines, mitigation planting requirements, and stop-work orders.

At 4th Generation Tree, our certified arborists guide homeowners, property managers, and contractors through San Luis Obispo’s permit process. We provide arborist reports, inspections, and professional removals that keep you fully compliant with local codes.

When Do You Need a Tree Removal Permit in San Luis Obispo?

According to the San Luis Obispo Municipal Code (Section 12.24.090), permits are required for most tree removals within city limits. You must apply if:

• The tree is a street tree (in the public right-of-way or parkway).
• The tree is a native species with a trunk ≥ 10 inches DSH (Diameter at Standard Height).
• The tree is a non-native species with a trunk ≥ 20 inches DSH.
• The tree is a palm with a trunk ≥ 12 inches DSH.
• The tree is within 25 feet of a creek or watercourse.
• The tree is tied to a construction, remodel, or development project.

Native trees covered under the 10″ rule include:

• Coast Live Oak
• Valley Oak (White Oak)
• California Laurel
• California Sycamore
• Southern California Black Walnut
• Willow
• Black Cottonwood
• California Holly (Toyon)
• Big Leaf Maple
• Box Elder

If your tree falls into any of these categories, you’ll need approval from the City of San Luis Obispo before starting work.

Permit Exemptions

You typically do not need a permit if ALL of the following are true:

• The tree is smaller than the DBH thresholds (native < 10″, non-native < 20″, palm < 12″).
• It is not a street tree in the public right-of-way.
• It is not within 25 feet of a creek or riparian zone.
• The property is not under special conditions tied to development approval.

What Happens If You Skip the Permit?

Removing a tree without approval can create serious problems:

• Fines of $500–$5,000 per tree depending on species and size.
• Stop-work orders on construction or remodeling projects.
• Mandatory mitigation planting, often at a ratio of 2:1 if not replaced onsite.
• Liability issues with HOAs, insurance, or neighbors.

For property owners, it’s always cheaper to follow the permit process than to deal with violations after the fact.

The Tree Removal Permit Process in San Luis Obispo

Here’s how the process typically works:

• Contact the City of San Luis Obispo Urban Forestry / Community Development Department to confirm requirements.
• Hire a certified arborist inspection and report (required for most removals).
• Submit the permit application with supporting documents and fees.

• Schedule the removal with a licensed, insured tree service like 4th Generation Tree.
