How Detroit Handles Landscaping Rules: A Practical Guide

Detroit maintains 197 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 Detroit falls on the strict-to-permissive spectrum compared to other cities.

Rainwater Harvesting

Rainwater harvesting is legal in Detroit with no state permit required; GLWA (Great Lakes Water Authority) combined sewer system makes rain barrels a proven CSO-reduction tool, and DWSD offers periodic rain barrel distribution programs.

Key details: State Law: Legal, no permit. Sewer System: GLWA combined. CSO Concern: Storm + sanitary mix. City Program: DWSD GSI discount. Indoor Use: Requires licensed plumber.

No permit required; no violations for installing barrels/cisterns for outdoor use. Improper connection to potable plumbing without a licensed plumber and RPZ backflow preventer: Michigan Plumbing Code violation, up to $500 fine + correction order.

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

Tree Removal & Heritage Trees

Street trees and trees in the public right-of-way in Detroit are city-owned and may only be removed by the General Services Department Forestry Division. Trees on private property are generally the owner's responsibility, supported by the Dead, Dangerous, and Diseased Tree Program.

Key details: Street/ROW Trees: City-owned (no resident removal). Forestry Contact: (313) 871-5461. Private-Tree Help: Dead, Dangerous & Diseased Program. Commercial Rules: Chapter 50 Art. XIV Div. 2. Service Request: Improve Detroit / 311.

Removing, topping, or trimming a city-owned street or park tree without authorization violates city rules and may carry replacement restitution. Failing to address dead or dangerous private trees threatening neighbors can trigger property-maintenance citations and city abatement.

Native Plants

Detroit allows and encourages native plantings. No ordinance requires a mowed lawn; but all vegetation must stay under 8 inches unless it qualifies as a managed natural area registered with BSEED.

Key details: Native Plantings: Legal. 8-inch Rule Exemption: Registered natural areas. Recommended Plants: Milkweed, coneflower, native grass. Support Orgs: Greening of Detroit, Detroit Audubon.

Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact [Detroit code enforcement](https://www.google.com/search?q=Detroit%20code%20enforcement) directly for current fines, enforcement procedures, and hearing options.

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

Tree Trimming

Property owners are responsible for trimming trees on private property and maintaining clearance over sidewalks (8 feet) and streets (14 feet) under Detroit Chapter 57.

Key details: Sidewalk Clearance: 8 feet. Street Clearance: 14 feet. Street Tree Owner: City (GSD Forestry). Utility Line: DTE Energy.

Water Restrictions

The Detroit Water and Sewerage Department (DWSD) does not impose mandatory odd/even or time-of-day outdoor watering restrictions citywide. Conservation is encouraged through voluntary tips; supply comes from the Great Lakes Water Authority via Lake Huron.

Key details: Supplier: Great Lakes Water Authority via DWSD. Mandatory Schedule: None citywide. Conservation Posture: Voluntary DWSD tips. Stormwater Rules: DWSD Drainage Charge program. Water Source: Lake Huron / Detroit River.

Because no mandatory outdoor watering ordinance is on the books, there are no routine city citations for sprinkler use. Owners can still face enforcement for wasting water, illegal hydrant use, or stormwater violations under separate DWSD rules.

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

Grass Height Limits

Detroit's Property Maintenance Code Section 8-15-35(a) requires every premises and exterior property to be maintained free from weeds or plant growth in excess of eight inches and from all noxious weeds. Enforcement is led by BSEED through Operation Compliance.

Key details: Maximum Height: 8 inches. Code Section: Detroit PMC 8-15-35(a). Exempt: Cultivated flowers & gardens. Enforcement: BSEED / Operation Compliance. Report: Improve Detroit.

Letting grass or weeds exceed 8 inches violates the Property Maintenance Code, enforced by BSEED. The city issues a notice, then abates the property and bills the owner for mowing plus an administrative fee. Unpaid charges become a lien.

Compared to other cities, Detroit takes a harder line on grass height limits. The enforcement and penalty structure reflects that.

Weed Ordinances

Detroit Property Maintenance Code Sec. 8-15-35(a) prohibits noxious weeds and any plant growth (excluding trees, shrubs, and cultivated gardens) over 8 inches. Michigan Public Act 359 of 1941 (Noxious Weed Act) supplements local authority with a commissioner-based abatement process.

Key details: Local Code: Detroit PMC 8-15-35(a). State Backstop: MI Public Act 359 of 1941. Height Trigger: 8 inches. Garden Exemption: Cultivated flowers/gardens OK. Enforcement: BSEED + state commissioner.

Allowing listed noxious weeds or any non-cultivated plant growth over 8 inches violates Sec. 8-15-35(a). BSEED issues notices, may mow and bill the property, and may lien unpaid charges. Repeat or commercial-scale violations can escalate to blight enforcement.

This is one of the stricter rules in Detroit's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Artificial Turf

Artificial turf is legal in Detroit for residential and commercial use. No HOA-style restrictions citywide. Must meet DWSD stormwater permeability standards if covering over 1,000 sq ft.

Key details: City Ban: None. DWSD Review: Over 1,000 sq ft. Historic District: COA required. Maintenance: Required; blight if failed.

Detroit is more permissive than most cities when it comes to artificial turf. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Detroit gives residents more room on landscaping rules. 4 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.

Keep in mind that Detroit can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
