Tree Removal & Heritage Trees

Removing, relocating or topping more than 25% of a heritage tree on private property in Rancho Cucamonga requires a tree removal permit from the planning director under Municipal Code section 17.16.080. A heritage tree is defined by size and trunk diameter thresholds that vary by property type.

Key details: Permit authority: Planning director. Governing section: Municipal Code § 17.16.080. Single-family threshold: 30 ft tall, 20-inch DBH trunk. Notice trigger: Removal of more than 5 trees. Fee waiver: Available if tree proven dead.

Removing, topping by more than 25%, or destroying a heritage tree without a permit violates section 17.16.080(D)(1) and is enforceable under the city's general Code penalty provisions in section 1.12.010, up to $1,000 and six months in jail as a misdemeanor, plus the city may require replacement planting as a condition of any later approval.

This is one of the stricter rules in Rancho Cucamonga's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Weed Ordinances

Every property owner in Rancho Cucamonga must abate fire hazards under Municipal Code Section 8.46.020, and Section 8.46.010 flags any dry grass over four inches tall as combustible vegetation. Section 8.46.040 sets that four-inch cap as the maintenance standard and requires clearing chaparral within 50 feet of structures, enforced by the Rancho Cucamonga Fire Protection District.

Key details: Governing section: Municipal Code § 8.46.040(B). Grass height limit: 4 inches maximum. Clearance near structures: 50 feet of chaparral. Enforcing agency: Rancho Cucamonga Fire Protection District. Emergency compliance: 72 hours for extreme hazards.

Failing to abate a fire hazard after notice, interfering with the fire chief's abatement work, or refusing entry to a district contractor is a misdemeanor under Section 8.46.090, punishable under Chapter 1.12 and enforceable through administrative citations. Beyond criminal penalties, the district can perform the abatement itself and bill the owner for the cost plus an inspection fee, and unpaid bills convert into a lien collected with property taxes under Section 8.46.070.

Tree Trimming

Rancho Cucamonga regulates trimming of street trees through the Public Works Department. Homeowners may trim private trees but must not damage parkway trees or encroach on public right-of-way without a permit.
