How Peoria Handles Landscaping Rules: A Practical Guide

Peoria maintains 100 local ordinances across all categories, and 7 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Peoria falls on the strict-to-permissive spectrum compared to other cities.

Native Plants

Native-plant landscaping is permitted in Peoria as a recognized alternative to traditional turf grass. Illinois HB 4604 (Public Act 102-0974, the Illinois Native Landscaping Act) explicitly protects residential native and pollinator landscapes from being treated as nuisances solely on the basis of height or perceived 'untidiness,' provided they are intentional and maintained. Peoria's Chapter 18 grass-height rule includes the standard exemption for cultivated landscapes.

Key details: State Protection: PA 102-0974 (HB 4604). Codified At: 65 ILCS 5/11-20-13.1. Status: Allowed as managed natural landscape. Required Element: Intentional + maintained. Still Required: Control of noxious/invasive species.

Citations issued against compliant managed natural landscapes can be appealed under PA 102-0974 (65 ILCS 5/11-20-13.1). Noxious weeds or invasive species within an otherwise-native garden remain enforceable under 505 ILCS 100/ with control orders and fines up to $1,500. Lack of maintenance allowing the garden to be overtaken by noxious species removes statutory protection.

Peoria is more permissive than most cities when it comes to native plants. That said, there are still limits.

Grass Height Limits

Peoria's Code of Ordinances Chapter 18 (Property Maintenance) and the city's nuisance abatement provisions declare grass and weeds in excess of 10 inches a public nuisance subject to abatement. Property owners receive notice and an opportunity to cut; failure to comply allows the city to mow at the property owner's expense, with costs assessed as a lien against the property.

Key details: Maximum Height: 10 inches. Code Authority: Peoria Code Ch. 18 (Property Maintenance). Notice Period: Typically 7-10 days. Lien Authority: 65 ILCS 5/11-20-7. Exception: Intentional native/ornamental landscaping.

Failure to abate weeds and grass after notice results in city mowing at typical contractor cost of $75-$300 per mow, plus an administrative fee. Repeated violations escalate to citations of $75-$750 per occurrence. Liens for unpaid mowing costs attach to the property and can be foreclosed under 65 ILCS 5/11-20-7.

Tree Trimming

Peoria's Public Works Department maintains parkway (right-of-way) trees and requires property owners to maintain street trees at the property line. Tree trimming on public property requires permission from Public Works; private trees that overhang sidewalks must be pruned to maintain at least 8 feet of clearance over sidewalks and 14 feet over streets. ComEd handles tree-line clearance under separate utility easements.

Key details: Parkway Trees: City-managed — Public Works/Forester. Sidewalk Clearance: 8 ft minimum (private overhang). Street Clearance: 14 ft minimum. Code Authority: Peoria Code Ch. 22. Utility Lines: Ameren Illinois 1-800-755-5000.

Pruning or removing a parkway tree without City Forester authorization is a violation of Chapter 22 with fines of $100-$500 per tree, plus replacement-cost assessment that can run $500-$2,000 per tree depending on species and size. Failure to maintain clearance over public sidewalks or streets can result in city pruning at owner cost.

Tree Removal & Heritage Trees

Peoria does not require a permit to remove a tree on private residential property. Parkway trees (those in the public right-of-way between sidewalk and curb) cannot be removed without authorization from the City Forester through Public Works. Where utility lines are involved, Ameren Illinois handles clearance work, and JULIE (811) must be called before any excavation that disturbs roots near underground utilities.

Key details: Private Trees: No municipal permit required. Parkway Trees: City Forester authorization required. Pre-Dig Call: JULIE 811 (220 ILCS 50/). Utility Line Trees: Ameren Illinois 1-800-755-5000. State Forestry Act: 525 ILCS 15/.

Removing a parkway tree without authorization is a Chapter 22 violation with fines of $100-$500 per tree plus a replacement-cost assessment ($500-$2,000+ per tree). Failure to call JULIE before excavation is a state-level violation under 220 ILCS 50/ with civil penalties up to $5,000. Damage to underground utilities during unauthorized excavation can result in repair-cost recovery.

If you are coming from a city with tighter rules, you will find Peoria gives residents more flexibility on tree removal & heritage trees.

Weed Ordinances

Peoria's Code of Ordinances Chapter 18 (Property Maintenance) declares weeds and rank vegetation over 10 inches a public nuisance, with the same enforcement framework as the grass-height rule. Noxious-weed species listed in the Illinois Noxious Weed Law (505 ILCS 100/) — including kudzu, perennial sow thistle, Canada thistle, and musk thistle — must be controlled regardless of height.

Key details: Height Trigger: 10 inches (Peoria Code Ch. 18). Noxious Weeds: Controlled regardless of height. State Statute: 505 ILCS 100/ Noxious Weed Law. Listed Species: Kudzu, Canada thistle, musk thistle, Palmer amaranth, others. Authority: IDOA + Peoria County SWCD.

Chapter 18 weed citations follow the same enforcement as grass height — $75-$300 per mow event plus administrative fee, with liens for unpaid charges. Noxious-weed violations under 505 ILCS 100/ are enforced by IDOA and can result in state-level orders requiring control with civil penalties up to $1,500 per occurrence.

Water Restrictions

Peoria does not have a year-round municipal water-restriction ordinance. Water service is provided by Illinois American Water (a private regulated utility) rather than a city water department. Drought-response restrictions, if declared, follow Illinois American Water's Drought Contingency Plan filed with the Illinois Commerce Commission; the city has no separate odd/even watering schedule.

Key details: Water Supplier: Illinois American Water (private). Regulator: Illinois Commerce Commission. Municipal Restrictions: None standing. Drought Response: Per utility tariff/contingency plan. Source: Illinois River.

Because Peoria has no municipal watering ordinance, drought-period violations are utility-level rather than citation-level — Illinois American Water can issue warnings and ultimately discontinue service to repeat violators under its ICC-approved tariff. Misuse of fire hydrants or unauthorized water connections is a city offense under Peoria Code Chapter 23 with fines of $100-$1,000.

If you are coming from a city with tighter rules, you will find Peoria gives residents more flexibility on water restrictions.

Composting

Backyard composting of yard waste and kitchen scraps is permitted in Peoria as long as the compost pile is maintained to prevent odor, vermin attraction, or other nuisance conditions under Chapter 18 (Property Maintenance). The Illinois Food Scrap and Composting Coalition and University of Illinois Extension provide guidance. Yard-waste curbside collection is also offered seasonally through the city's contracted hauler.

Key details: Backyard Composting: Allowed if not a nuisance. Avoid in Compost: Meat, fish, dairy, oils. Landfill Ban (yard waste): 415 ILCS 5/22.22. Curbside Yard Waste: Seasonal, via city contractor. Resource: University of Illinois Extension.

Compost piles that produce odor, attract rats, or accumulate prohibited materials (meat, dairy, fish) can be cited under Peoria Code Chapter 18 with fines from $75-$500 per occurrence and daily continuing-violation penalties. Disposing of landscape waste in regular trash bound for landfills violates 415 ILCS 5/22.22 and can result in IEPA citations.

Peoria is more permissive than most cities when it comes to composting. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Peoria gives residents more room on landscaping rules. 4 of the 7 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.
