Landscaping Rules in Oklahoma City, OK

If you live in Oklahoma City or are thinking about moving there, landscaping rules are one of those things you probably won't think about until they affect you directly. Oklahoma City has 6 specific rules on the books covering different aspects of landscaping rules, and some of them might surprise you.

Water Restrictions

Oklahoma City's City Manager can declare mandatory water-use restrictions during shortages, main breaks, or pressure loss, and violators face Class A misdemeanor charges for every day of noncompliance.

Key details: Governing section: § 57-2, Water Resources chapter. Trigger: Main break, pressure loss, supply shortage. First offense: Class A misdemeanor. Repeat (4th+) offense: Class B misdemeanor. Enforcement tool: Water shutoff under § 55-82.

First offense is a Class A misdemeanor; a fourth or later offense is Class B. Each violation day and each service address counts separately, and the City may physically shut off water service.

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

Weed Ordinances

Oklahoma City caps grass and weeds at 12 inches tall on any lot; taller growth is declared a public nuisance under the Municipal Code.

Key details: Height limit: 12 inches. Enforcing agency: Director of Neighborhood Enhancement. Notice period: 10-day written notice before abatement. Penalty: Up to $500 fine per day. Farm exemption: 150+ feet from non-farm zoning.

Ignoring the mow notice lets the City abate the nuisance and bill the owner; unpaid costs become a lien collected like property taxes. Each day of violation is a separate Class A offense, fines up to $500.

Composting

Oklahoma City's zoning code requires backyard compost piles in residential districts to sit in the rear yard, stay pest-free, and avoid odor and runoff violations under Section 59-9350.21.1.

Key details: Location rule: Rear yard only. Pest control: Must prevent insects, rats, vermin. Odor standard: Must meet Environmental Performance Standards. Runoff: Must not drain onto neighbors or waterways. Zones covered: R-1 through R-MH-2 residential districts.

Composting outside the rear yard, or a pile that draws pests, reeks, or drains runoff onto neighbors, violates § 59-9350.21.1 and can trigger a zoning code enforcement case and cleanup order.

Tree Trimming

Oklahoma City property owners must trim trees and shrubs that overhang or obstruct any adjacent street, sidewalk, or streetlight.

Key details: Governing section: Municipal Code § 53-21. Who must trim: Owner of the abutting lot. Notice period: 5 to 10 days to comply. Non-compliance: Nuisance; each day = separate offense. Enforcement remedy: City abates cost, taxes property.

Untrimmed vegetation blocking a street, sidewalk, or streetlight is declared a nuisance. After written notice giving 5-10 days to fix it, each day of continued failure is a separate offense; the City can abate the nuisance itself and assess the cost as a special tax against the property.

Rainwater Harvesting

Oklahoma City allows rain barrels and cisterns at home and community gardens, but caps visible above-ground tanks at 85 gallons unless screened from the street.

Key details: Screen pore size: 1 mm or less. Visible container cap: under 85 gallons. Max visible containers: 2 per structure. Placement limit: not in front of front wall.

No standalone fine is listed for this provision; enforcement runs through the Planning Department's zoning code compliance process, which can require removal or relocation of a noncompliant container and cites property owners for zoning violations under Chapter 59.

Tree Removal & Heritage Trees

Removing, cutting, or trimming any tree, plant, or shrub on public property in Oklahoma City, including parkways and street rights-of-way, requires a permit from the City's enforcement officer under the Code of Forestry.

Key details: Permit issuer: Enforcement officer over that City property. Covered location: Public property, parkways, street rights-of-way. Governing law: Code of Forestry, Chapter 53. Penalty: Each day is a separate offense.

Chapter 53's general violations clause (§ 53-75) makes each day of an ongoing violation, and each separate infraction at a different location, its own separate offense.

The Bottom Line
