Oak Park's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Oak Park, Illinois, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Tree Trimming

Oak Park treats trees and shrubs that block sidewalks, streets, streetlights or sightlines as public nuisances. Branches overhanging a clear sight area must be trimmed to at least 7 feet, and owners get 30 days' notice before the Village trims and liens the property.

Key details: Governing law: Oak Park Village Code § 25-1-5, § 25-1-6. Clearance over sidewalk sight area: Trim to at least 7 feet. Shrub height cap at intersections: 30 inches. Abatement notice period: 30 days. New tree setback from intersection: 25 feet from sidewalk corner.

Violating Chapter 25 or ignoring a Forester's abatement notice is punishable by the fine set in Village Code § 1-1-5. If a Village-owned tree or plant is injured, mutilated or killed by the violation, the violator must also pay the replacement or repair cost, valued under the International Society of Arboriculture's plant appraisal guide.

Composting

Oak Park residents may keep a backyard compost pile for yard waste and compostable kitchen scraps under Village Code section 20-7-2, but garbage other than vegetable waste and untreated animal excreta are barred as ingredients, and an unmanaged, un-aerated pile can be declared a public nuisance subject to abatement.

Key details: Allowed ingredients: yard waste and compostable kitchen waste only. Barred ingredients: garbage (except vegetable waste), untreated animal excreta. Maintenance standard: regular aeration, active management required. Non-compliant pile: may be declared a public nuisance. Village compost cart alternative: $16.80/month, $8.40/month in winter.

A compost pile that violates the aeration, active-management, or prohibited-ingredient standards of section 20-7-2 can be declared a public nuisance under the Village's nuisance provisions, subjecting the property owner to abatement action and prosecution rather than a fixed compost-specific fine; broader Article 7 violations are separately punishable under sections 20-7-19 and 20-7-20, with a $125.00 payment available within ten business days to avoid prosecution and a $750.00 maximum penalty.

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

Water Restrictions

From May 15 through September 15 each year, the Village of Oak Park, Cook County, Illinois, limits outdoor watering to an odd-even schedule tied to street address, and bars lawn sprinkling from 10 a.m. to 4 p.m., under Village Code Section 26-5-6. The Director of Public Works and Chief of Police enforce it, with fines under the Village's general penalty schedule.

Key details: Restricted season: May 15 through September 15. Watering schedule: Even addresses/even days, odd/odd (Mon-Fri). Midday sprinkling ban: 10:00 a.m. to 4:00 p.m., no exceptions by address. New lawn exemption: Sod/seed under 3 months old. Enforcing officials: Director of Public Works, Chief of Police.

Watering on the wrong day or during the 10 a.m. to 4 p.m. sprinkling ban violates Section 26-5-6 and is fined under the Village's Section 1-1-5 general penalty schedule; the property owner, tenant, custodian, manager, or registered water-meter applicant is liable. A repeated violation after a Village notice is a separate offense each time and can be pursued as a nuisance abatement under Chapter 16.

Tree Removal & Heritage Trees

In the Village of Oak Park, Cook County, Illinois, no one but the Village Forester or a Village-hired contractor may cut, damage, remove, or transplant a tree on Village-owned property, including parkway trees, without written approval under Village Code Section 25-1-4. Removal of trees on private property is governed instead by the separate Zoning Ordinance, not this section.

Key details: Approval authority: Village Forester (written approval required). Applies to: Village-owned property, including parkways. Application review time: 7 days to grant or deny. Work window once approved: 30 days from approval. Contractor liability insurance: $1,000,000 per accident / $2,000,000 aggregate.

Removing, damaging, or cutting a Village-owned or parkway tree without the Forester's written approval violates Section 25-1-4 and is punishable under Section 25-1-8 by a fine under the Chapter 1, Section 1-1-5 general penalty schedule. The violator also owes the cost of repairing or replacing the tree, valued under the International Society of Arboriculture's Guide for Plant Appraisal, and the Forester can order work stopped and rescind any approval obtained.

Weed Ordinances

Oak Park caps weeds and grass at 8 inches on any lot in the Village. Owners who ignore a cutting notice face Village-ordered mowing, a weedkiller spray lien on the property, and citations from five separate Village departments.

Key details: Height limit: 8 inches (grass included). Early payment amount: $125 within 10 business days. Maximum penalty: $750 per violation. Village remedy: Village may cut and spray, then lien the property. Enforcing departments: Police, Housing, Building & Zoning, Health, Public Works.

Citations issue from the Police Department, Housing Division, Building and Zoning Division, Health Department, or Public Works Department under section 20-7-19. Pay $125 within 10 business days of the citation to avoid prosecution; otherwise fines run up to $750 per violation under section 20-7-20. The Village can also cut the weeds, spray weedkiller, and record a lien for its costs under sections 20-7-15 and 20-7-16.

Native Plants

Oak Park's Property Maintenance Code exempts cultivated gardens, including beds planted or naturally recruited with native plants, from the Village's 8-inch weed height limit, as long as the bed is intentionally grown and cared for rather than left wild.

Key details: Governing law: Oak Park Village Code § 7-13-2. Base code: 2024 International Property Maintenance Code, as amended. General weed limit: 8 inches for turf/plant growth. Exempt category: Cultivated gardens, incl. native plantings. Still regulated: Noxious weeds.

A property whose vegetation does not qualify as a cultivated garden and exceeds the 8-inch weed height limit is subject to a notice of violation and prosecution under Section 108.3 of the Property Maintenance Code; on continued failure to cut, the Village or its contractor may enter and cut the growth and bill the owner or responsible agent for the cost.

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

The Bottom Line

Compared to many U.S. cities, Oak Park gives residents more room on landscaping rules. 2 of the 6 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.
