San Bernardino County Tree Trimming Laws: What You Need to Stay Code-Compliant

Avoid Fines, Protect Property Lines, and Keep Your Trees Safe and Legal

Thinking about trimming that overgrown tree in your yard? Before you grab your chainsaw or call a landscaping crew, make sure you’re not stepping into a legal tangle. San Bernardino County has specific tree trimming laws designed to protect property, people, and the environment.

Failing to follow these rules can lead to fines, liability issues, or even lawsuits — especially if your trimming affects neighboring properties or public right-of-ways.

Here’s everything homeowners, property managers, and landscapers need to know to stay code-compliant when it comes to tree trimming in San Bernardino County.

Why Tree Trimming Laws Exist

Trees aren’t just landscape features — they’re part of a shared ecosystem and legal framework. San Bernardino County tree laws are meant to:

  • Prevent property damage from falling limbs
  • Maintain visibility for roads and intersections
  • Protect wildlife habitats
  • Avoid disputes between neighbors
  • Preserve public and private safety

Reference: San Bernardino County Code of Ordinances, Development Code § 88.01 – Plant Protection and Management

Key Tree Trimming Regulations in San Bernardino County

While tree laws can vary based on your city or HOA, here are the general rules that apply county-wide:

1. Private Property Tree Trimming

  • You can trim trees on your own property — but only up to your property line.
  • You may not trim or cut branches from a neighbor’s tree that extend beyond the boundary without consent, especially if it causes harm.

Reference: California Civil Code § 833–834 – Trees whose trunks stand partly on the land of two or more coterminous owners belong to them in common. Branches may be trimmed to the property line but not beyond.

2. Protected Trees

Some trees fall under county or city protections — particularly native, historic, or large-diameter trees. You may need a permit to trim or remove them.

Protected areas may include:

  • Hillside and desert overlay zones
  • Environmentally sensitive lands
  • Native oak or Joshua trees (with state or local protection)

Reference: San Bernardino County Development Code § 88.01.060 – Tree & Plant Preservation
Reference: California Native Plant Protection Act (NPPA) — PRC § 1900 et seq.

3. Trees Near Utility Lines

Trimming trees near power lines is not allowed unless you're authorized. Only utility companies or licensed contractors can perform this safely.

Reference: Southern California Edison – Vegetation Management Guidelines
Reference: California Public Utilities Commission (CPUC) – General Order 95, Rule 35

4. Street Trees & Sidewalks

Trees between the sidewalk and street typically belong to the city or county and are considered public right-of-way trees.

You may be responsible for maintenance but need a permit for trimming or removal.

Reference: San Bernardino County Public Works – Encroachment Permits

5. Visibility and Safety Regulations

The county recommends the following clearances:

  • 8 feet above sidewalks
  • 14 feet above roadways
  • No obstruction of views at intersections or driveways

Reference: California Vehicle Code § 21212; Local Traffic Safety Ordinances – Visibility Triangle Guidelines

When Do You Need a Permit?

Permits are often required when:

  • Trimming protected trees
  • Performing work in conservation zones
  • Removing any tree over a certain diameter

Reference: San Bernardino County – Planning Division Permit Portal

Fines and Penalties

Unpermitted removal or damage to protected trees can result in:

  • Fines
  • Replacement requirements
  • Project delays or permit suspensions

Reference: San Bernardino County Code Enforcement – Property Condition & Vegetation Violations

Best Practices to Stay Compliant

  • Call 811 before digging near tree roots
  • Stay within your legal property boundary
  • Document your trimming work
  • Get written neighbor consent when trimming shared trees
  • Hire tree service professionals
