How Pasadena Handles Landscaping Rules: A Practical Guide

Pasadena maintains 170 local ordinances across all categories, and 8 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Pasadena falls on the strict-to-permissive spectrum compared to other cities.

Composting

Pasadena lets residents compost organic waste on site instead of using the city's organics cart, but caps informal or community composting at 100 cubic yards and 750 square feet under the definition adopted in Municipal Code Section 8.66.030(F). Franchise haulers that do collect organics must haul it only to a state-certified facility.

Key details: On-site composting allowed: Yes, under § 8.66.050(l). Size cap: 100 cubic yards / 750 square feet (§ 8.66.030(F)). State reference: Tracks 14 CCR § 17855(a)(4). Franchisee delivery rule: Must use a state-certified composting facility (§ 8.60.275).

The code does not set a specific residential composting citation; exceeding the 100 cubic yard or 750 square foot Community Composting threshold in Section 8.66.030(F) takes an operation outside that definition and into the state's separately permitted composting facility rules. A franchise hauler that delivers collected organics to a facility that is not permitted or certified by the State of California violates Section 8.60.275 and is subject to the franchise enforcement and citation provisions of Chapter 8.61.

If you are coming from a city with tighter rules, you will find Pasadena gives residents more flexibility on composting.

Weed Ordinances

Pasadena treats grass over 10 inches tall as 'overgrown vegetation' and a public nuisance under its property maintenance code, while a separate 1934 weed abatement ordinance lets the city post notices, remove weeds and rubbish itself, and bill the property owner. Owners get 10 days to comply or appeal before the city acts and assesses the cost as a lien.

Key details: Grass height limit: 10 inches before it is 'overgrown vegetation'. Notice-to-comply window: 10 days to remove weeds or appeal. Appeal body: City council under Section 8.48.050. Delinquency penalty: 10 percent plus $2.00 publication fee. Burning ban: Weed burning prohibited except narrow firebreak exception.

Unpaid weed-removal charges become a special assessment against the property under Section 8.48.070, collected the same way as municipal taxes, with a 10 percent delinquency penalty plus a $2.00 publication fee added under Section 8.48.080 if unpaid by June 5th following the city's work. Because grass over 10 inches is also a public nuisance under Section 14.50.040(8), the neighborhood services administrator can separately pursue the 14.50.060 abatement-hearing process for the same violation.

Rainwater Harvesting

Rainwater harvesting is legal and encouraged in California. No permit required for rain barrels. Pasadena's LID requirements encourage on-site water retention. Pasadena Water & Power may offer conservation rebates.

Key details: Legal: Yes, statewide. Rain Barrels: No permit required. LID: On-site retention encouraged. Rebates: May be available from PWP.

Tree Removal & Heritage Trees

Removing a protected tree on private property in Pasadena requires a city permit under Municipal Code Section 8.52.070(B). The city manager must deny the permit unless one of six specific findings applies, and decisions are due within 15 business days of a complete application.

Key details: Permit required: Before removing any protected tree. Where to apply: City manager, Chapter 17.60 process. Approval standard: Denied unless one of six findings met. Decision deadline: Within 15 business days. Mitigation: Replacement trees or fee required.

Removing or injuring a protected tree without an approved permit, or violating a permit's conditions, is a misdemeanor punishable by up to $1,000 and six months in jail under Section 8.52.160(A), or an infraction under subsection (B). The city may also seek a civil penalty of up to $5,000 per tree, or the tree's full appraised value, plus a one-year hold on building permits for the property under Section 8.52.160(D)-(E).

This is not one of those rules that cities tend to ignore. Pasadena actively enforces its tree removal & heritage trees requirements.

Water Restrictions

Pasadena Water and Power enforces water conservation measures year-round. Outdoor watering is limited to specific days and times. The city offers rebates for turf removal and drought-tolerant landscaping.

Key details: Watering Time: No watering 9 AM–5 PM. Designated Days: Varies by water shortage level. Runoff: Prohibited onto sidewalks/streets. Turf Rebate: $2+ per square foot.

First violation results in a warning. Subsequent violations carry fines from $100 to $500 or more depending on the level of water shortage.

Tree Trimming

Pasadena has a strong urban forestry program. Property owners must maintain trees to provide clearance over sidewalks (8 feet) and streets (14 feet). City-owned street trees are maintained by the Public Works Department.

Key details: Sidewalk Clearance: 8 feet minimum. Street Clearance: 14 feet minimum. City Trees: Maintained by Public Works. Authorization: Required for city tree work.

Failure to maintain clearance results in code compliance notices. Unauthorized trimming of city trees may result in fines and replacement costs.

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

Artificial Turf

Artificial turf is permitted in Pasadena as a drought-tolerant landscaping option. CA Gov Code 65595 prohibits cities from banning drought-tolerant landscaping. Pasadena Water & Power supports water conservation alternatives.

Key details: Allowed: Yes, as drought-tolerant option. State Law: CA Gov Code 65595. MWELO: Compliance encouraged. Water Provider: Pasadena Water & Power.

Native Plants

Pasadena's Landscape Standards direct commercial, industrial, hillside and multi-family projects to favor drought-tolerant and native plant species, cap ornamental turf at 20% of landscaped area under City of Gardens standards, and exempt single-family RS and RM-12 lots from the chapter entirely.

Key details: Applies to: Commercial, industrial, hillside, multi-family. Exempt: RS and RM-12 single-family zones. Plant emphasis: Drought-tolerant and/or native species. City of Gardens turf cap: 20% max of landscaped area. Commercial setback landscaping: 50% of front/corner setback.

A project that fails to submit or follow its approved preliminary landscape plan cannot receive a Building Permit for the required setback areas, and the Zoning Administrator, joined by the Fire Chief for Hillside overlay projects, can withhold approval or require replanting to bring turf coverage, plant selection, or setback landscaping into compliance with Section 17.44.070 before construction proceeds.

The Bottom Line

Pasadena is tougher than many cities when it comes to landscaping rules. Out of the 8 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Pasadena, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
