📋 What is Landscaping Negligence in California?

Landscaping negligence occurs when a landscaper, gardener, or landscape contractor fails to exercise reasonable care in performing landscaping work, resulting in property damage. California requires landscaping contractors (C-27 license) to be licensed by the Contractors State License Board (CSLB) for projects over $500. Unlicensed work provides additional legal leverage.

Common Types of Landscaping Damage

💧 Irrigation Damage

Faulty sprinkler installation, water damage to foundation, flooding, pipe failures, drainage problems

🌲 Tree Removal Disputes

Unauthorized tree removal, improper pruning, damage to neighboring property, stump removal damage

🌱 Plant/Lawn Damage

Killing plants through improper care, pesticide damage, wrong plant selection, improper grading

🏗 Hardscape Damage

Damaged patios, retaining wall failures, improper drainage, cracked concrete, settling issues

👍 What You Can Recover

  • Repair/replacement costs - Cost to fix or replace damaged landscaping
  • Property damage - Foundation, structures, neighboring property
  • Diminished property value - If damage reduces home value
  • Treble damages for trees - Up to 3x value for wrongful tree cutting
  • Refund of payments - Money paid for negligent work

CSLB Licensing Requirements

📚 C-27 Landscaping Contractor License

California requires a C-27 Landscaping Contractor license for landscaping work exceeding $500 (labor and materials combined). C-27 contractors can install irrigation systems, build retaining walls under 4 feet, and perform general landscaping. Unlicensed contractors cannot sue to collect payment and may face penalties.

Benefits of Hiring Unlicensed Contractor

If you unknowingly hired an unlicensed contractor, you may recover ALL money paid under Business & Professions Code 7031. The unlicensed contractor cannot enforce the contract or sue you for payment. You can also file a complaint with the CSLB for unlicensed activity.

👥 Tree Service Requirements

Tree removal and major tree work requires either a C-27 (landscaping), C-61/D-49 (tree service), or other appropriate license. Arborists should be certified by ISA (International Society of Arboriculture). Unauthorized tree removal can result in treble damages under Civil Code 3346.

⚠ Check CSLB License Status

Before sending your demand, verify the contractor's license status at cslb.ca.gov. If they are unlicensed or their license was expired when work was performed, you have additional claims under B&P Code 7031 to recover all payments made.
