Chico's Landscaping Rules: The Rules That Matter
Every city handles landscaping rules a little differently. In Chico, California, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Composting
Chico has no separate backyard compost-bin ordinance, but its zoning code sets real on-site composting standards for community gardens: onsite materials only, five-foot setbacks, and a nuisance limit.
Key details: Setback from property line: 5 feet minimum. Allowed materials: Onsite/member-generated only. Nuisance standard: No worse than a residence. Applies to: Community garden sites.
A community garden that composts off-site material, sites a compost area within five feet of a property line, or lets odors or flies become a nuisance is subject to the same code enforcement process as other zoning standards violations; the property owner is the responsible party.
Tree Trimming
Chico bans letting private tree or shrub branches hang within 10 feet of the ground over a sidewalk or street.
Key details: Minimum clearance: 10 feet above sidewalk/street. Applies to: Private trees and shrubs. Enforcement: Misdemeanor or infraction. Governing chapter: CMC Ch. 14.40, Tree Law.
Violating the Tree Law is a misdemeanor or infraction, enforceable by a criminal action from the city attorney or an administrative citation under CMC Chapter 1.15.
Rainwater Harvesting
Chico counts rain barrels and cisterns as an approved site design measure: developments adding 2,500 to 5,000 square feet of impervious surface can meet the city's runoff-reduction requirement in part by installing a system that collects and stores storm water from a roof.
Key details: Governing section: Municipal Code § 15.50.080(A). Trigger: 2,500-5,000 sq ft impervious surface. Rain barrel status: One of six approved options. Plan stamp: California civil engineer required. Larger projects: 5,000+ sq ft is a regulated project.
Projects that skip a required site design measure can't clear plan review; noncompliant runoff is enforceable as a Chapter 15.50 violation subject to abatement and civil penalties.
Chico is more permissive than most cities when it comes to rainwater harvesting. That said, there are still limits.
Weed Ordinances
Chico sets no specific inch or foot height for weeds and grass; Municipal Code § 1.14.030 instead makes hazardous or unsightly overgrown vegetation a nuisance subject to notice and city abatement.
Key details: Height threshold: None specified, nuisance standard instead. Trigger: Hazardous or unsightly overgrown vegetation. Process: Director notice, then abatement order. Cost recovery: City bills owner for cleanup. Governing chapter: Chapter 1.14 Nuisance Abatement.
Failure to abate nuisance vegetation after a director's order can trigger City-performed abatement under § 1.14.100, with owners billed for labor, contractor costs, re-inspection fees, and attorney's fees.
Tree Removal & Heritage Trees
Chico lets owners, or applicants with owner consent, petition to designate qualifying oaks, sycamores, and other significant trees as Heritage Trees, which are then recorded on title and removable only through the standard tree permit process.
Key details: Designation criteria: Native oak/sycamore, 36"+ DBH, or unique. Reviewed by: Urban Forest Manager, Park Commission. Final decision: City Council. Removal governed by: Chapter 16.66 permit process.
Removing a designated Heritage Tree outside the Chapter 16.66 permit process triggers the same civil penalties as unpermitted tree removal, twice the tree's appraised value or $5,000, whichever is greater, under § 16.66.130.
Native Plants
New commercial and multi-family landscaping in Chico must be at least 90% drought-tolerant or native plants suited to the local climate, per Chico Municipal Code Section 19.68.050.
Key details: Min. drought-tolerant/native share: 90% of non-turf plants. Max less drought-tolerant share: 10%, grouped together. Exemption: Single-family homes. Turf/water feature cap: 25% of irrigated area.
Landscaping installed out of compliance with an approved plan can block issuance of a certificate of occupancy, and the planning director can require changes to bring plant selection back into the required 90/10 drought-tolerant mix.
The Bottom Line
Chico's landscaping rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Chico is broadly strict or permissive.
