Landscaping Rules in Chino, CA: What Residents Actually Need to Know

If you live in Chino or are thinking about moving there, landscaping rules are one of those things you probably won't think about until they affect you directly. Chino has 8 specific rules on the books covering different aspects of landscaping rules, and some of them might surprise you.

Weed Ordinances

Chino makes property owners responsible for clearing noxious weeds, vegetation, and dry grass from the sidewalks and parkways fronting their land, backed by a notice-and-lien abatement process.

Key details: Governing section: CMC § 8.20.010. Height standard: No numeric limit; "dry grass" nuisance. Compliance window: 14 days after notice to remove. Non-compliance cost: City abatement billed/lien to owner.

Failing to remove noxious weeds, vegetation, or dry grass from the sidewalk and parkway strip within fourteen days of a city notice to remove triggers city-ordered abatement, with the removal cost billed to the owner or levied as a tax lien under § 8.20.040.

Tree Removal & Heritage Trees

Chino requires the Director of Community Development's written approval before removing a mature tree, oak trees over 8 inches, other trees over 10 inches, or multi-trunk trees with 38+ inches combined circumference, on qualifying development.

Key details: Section: CMC § 20.19.040(F). Mature oak threshold: trunk over 8 inches. Mature other-tree threshold: trunk over 10 inches. Single-family exemption: trees under 15 inches. Adopted: Ord. 2015-008 (2015); Ord. 2016-005 (2016).

No fine is printed here. Removal instead triggers mandatory replacement, up to three replacement trees per tree removed (Table 20.19-4.1), or an in-lieu fee to the city's tree fund if on-site planting isn't feasible.

Compared to other cities, Chino takes a harder line on tree removal & heritage trees. The enforcement and penalty structure reflects that.

Composting

Chino requires new and rehabilitated landscape projects over the MWELO threshold to work compost into the soil at a minimum rate of four cubic yards per 1,000 square feet before planting.

Key details: Governing section: CMC § 8.18.150(C)(1)(a). Minimum compost rate: 4 cu. yd. per 1,000 sq. ft.. Incorporation depth: 6 inches into soil. Exemption: Soil already >6% organic matter.

Installing a covered new or rehabilitated landscape without incorporating the required compost rate, or without the soil-preparation documentation in the landscape design plan, is a violation enforceable through the city's landscape permit and plan-check process under § 8.18.150 and § 20.19.040.

Artificial Turf

Chino allows artificial turf in landscaped yards, but caps it at 30% of required landscape coverage and demands lifelike blades, proper drainage, and city plan-check review.

Key details: Allowed: yes, citywide. Coverage cap: 30% of required landscape. Must pair with: live plant material. Banned substitute: plain plastic/nylon carpeting. Adopted: Ord. 2015-008; amended Ord. 2016-005.

Installing plastic or nylon carpeting instead of lifelike synthetic grass, skipping the required drainage layer, or exceeding the 30% landscape-coverage cap without director of community development sign-off puts a project out of compliance.

Tree Trimming

In Chino, no one may remove, trim, prune, or cut a tree standing on a public street or planting strip without written permission from the city service department, which then supervises the work.

Key details: Section: CMC § 12.16.240. Applies to: street and planting-strip trees. Permit from: city service department. Source: carried from prior code § 24-10(a).

Violating this chapter is a misdemeanor punishable by a fine up to $500, up to six months in county jail, or both (CMC § 12.16.300).

This is not one of those rules that cities tend to ignore. Chino actively enforces its tree trimming requirements.

Rainwater Harvesting

New and rehabilitated Chino landscape projects must build in stormwater practices that hold twenty-four hours of runoff on site, boosting infiltration and water quality under the city's landscaping chapter.

Key details: Retention window: 24-hour capacity required. Applies: new landscape ≥500 sq. ft.. Applies: rehab landscape ≥2,500 sq. ft.. Plan must show: rain-harvesting locations. Adopted: Ord. 2015-008; amended Ord. 2016-005.

A landscape design that omits the required 24-hour on-site retention or infiltration capacity, or a documentation package that fails to show rain-harvesting technology locations, doesn't clear plan-check review by the director of community development.

Water Restrictions

Chino permanently bans automated irrigation from 6 a.m. to 8 p.m. and caps non-drip sprinkler runtime at fifteen minutes per station per day, citywide.

Key details: Automated irrigation hours: Banned 6 a.m.–8 p.m.. Runtime cap: 15 min/day/station, non-drip. Hand watering: Allowed anytime, shutoff nozzle. Runoff onto pavement: Prohibited at all times. Governing ordinance: Ord. 2009-04, § 1, 2009.

First violation draws a written warning; second draws a final notice. Third through fifth violations within twelve months add $50, $100, then $150 surcharges to the water bill under § 13.05.120.

Native Plants

For existing single-family front yards, Chino encourages, but does not mandate, landscaping built primarily around native or climate-appropriate plants that need less water in warm months.

Key details: Status: encouraged, not required. Applies to: existing single-family front yards. Paired cap: turf ≤25% of landscape area. Paired floor: water-efficient plants ≥50%. Adopted: Ord. 2015-008; amended Ord. 2016-005.

The native-plant language itself isn't independently enforceable: it's encouragement, not a mandate. What is enforceable in the same subsection are the numeric caps: turf over 25% of the required landscape area, or hardscape over 25%, fails plan-check review by the director of community development.

If you are coming from a city with tighter rules, you will find Chino gives residents more flexibility on native plants.
