How Pasadena Handles Landscaping Rules: A Practical Guide

Pasadena maintains 118 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.

Weed Ordinances

Pasadena requires property owners to maintain yards free of excessive weeds and overgrown vegetation. Particularly strict enforcement in fire hazard areas. Code Compliance addresses violations through investigation and citation.

Key details: Maintenance: Required year-round. Fire Zones: Enhanced enforcement. Enforcement: Code Compliance Division. Contact: (626) 744-8633.

Non-compliant properties receive abatement notices. If not cleared, the county performs the work and assesses costs plus fees on the property tax bill.

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.

No penalties for standard residential collection. Large cistern installations without building permit: standard building code violation $100 to $500.

Pasadena is more permissive than most cities when it comes to rainwater harvesting. That said, there are still limits.

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.

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

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.

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.

Generally no penalties for installation. Non-compliant drainage may require correction. HOA fines may be unenforceable where state law protects turf rights.

The rules around artificial turf in Pasadena lean permissive, but that does not mean anything goes.

Native Plants

Pasadena encourages native and drought-tolerant landscaping consistent with MWELO. The city's Tree Protection Ordinance (PMC 8.52) specifically protects native tree species. CA Gov Code 65595 prevents cities from prohibiting drought-tolerant landscaping.

Key details: State Law: CA Gov Code 65595. MWELO: Compliance required for new landscapes. Native Trees: Protected under PMC 8.52. Incentives: Rebates may be available.

Varies by jurisdiction. HOA fines for non-compliance may be unenforceable if state law protects xeriscaping rights.

The rules around native plants in Pasadena lean permissive, but that does not mean anything goes.

Grass Height Limits

Pasadena's property maintenance standards require vegetation to be maintained at reasonable heights. Overgrown properties are addressed by the Code Compliance Division. Dry, dead vegetation must be cleared as a fire hazard.

Key details: Maximum Height: Generally 12 inches. Fire Hazard: Dead vegetation must be cleared. Enforcement: Code Compliance Division. Abatement: City may clear and bill owner.

Violations result in notices to correct. The city may abate and bill the property owner. Fire hazard vegetation carries additional penalties.

Tree Removal & Heritage Trees

Pasadena requires a tree removal permit for protected trees on private property. Public trees and landmark trees have additional protections. Replacement planting may be required.

Key details: Permit: Required for protected trees. Heritage Trees: Highest protection level. Replacement: Required when removal approved. Fine: Up to 3x appraised tree value.

Unauthorized removal of protected trees results in fines of up to three times the appraised value of the tree plus mandatory replacement planting.

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

The Bottom Line

Compared to many U.S. cities, Pasadena gives residents more room on landscaping rules. 3 of the 8 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
