📋 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

Faulty sprinkler installation, water damage to foundation, flooding, pipe failures, drainage problems
🌲 Tree Removal Disputes

🌱 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

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.
⚖ Legal Basis
California provides multiple legal theories for recovering landscaping damage.
Key California Statutes
Business & Professions Code Section 7031 (Unlicensed Contractors)
Unlicensed contractors cannot sue to collect payment for work requiring a license. Property owners can recover all compensation paid to unlicensed contractors. This is a powerful tool - you may get a full refund regardless of work quality.
Civil Code Section 3479 (Nuisance)
Anything that is injurious to health, indecent, offensive to the senses, or obstructs the free use of property is a nuisance. Drainage problems, flooding, or other ongoing issues from negligent landscaping can constitute a nuisance.
Civil Code Section 3346 (Treble Damages for Trees)
Anyone who wrongfully cuts down or damages trees on another's property is liable for treble (3x) the value of the trees. This applies to unauthorized removal and extends to landscapers who damage trees without permission.
Code of Civil Procedure Section 337 (Statute of Limitations)
You have 4 years to bring a breach of written contract claim, 2 years for oral contracts, and 3 years for property damage. The discovery rule may extend deadlines if damage was not immediately apparent.
Elements You Must Prove
- Contract or duty - Landscaper was hired or owed a duty of care
- Breach - Work was negligent or below professional standards
- Causation - The breach caused your property damage
- Damages - You suffered actual monetary loss
💡 Neighbor Disputes and Trees
If a landscaper's work damaged your neighbor's property, you may be liable to your neighbor. Conversely, if your neighbor's landscaper damaged your property, you can make a claim against both the neighbor and the landscaper.
