Invasive Plant Rules in Oklahoma City, OK: What Residents Actually Need to Know

By CityRuleLookup Editorial Team

If you live in Oklahoma City or are thinking about moving there, invasive plant rules are one of those things you probably won't think about until they affect you directly. Oklahoma City has 2 specific rules on the books covering different aspects of invasive plant rules, and some of them might surprise you.

Prohibited Species

Oklahoma City outlaws poison ivy, poison oak, and poison sumac on any lot at any height, classifying them as noxious plants owners must cut, remove, or destroy or face a nuisance-abatement order and lien.

Key details: Prohibited species: poison ivy, oak, sumac. Threshold: any height or maturity stage. Notice period: 10 days to cut/remove. Non-compliance cost: city abates, files property lien. Penalty: each day a separate offense.

Failure to remove poison ivy, oak, or sumac after a 10-day director's notice lets the city abate the nuisance itself and lien the property for costs (§ 35-64, § 35-67, § 35-68). Owners who violate the article are guilty of a municipal offense, with each day of continued violation a separate offense (§ 35-69).

Front Yard Gardens

OKC exempts tended food gardens from its 12-inch weed-height nuisance rule, but poison ivy, oak, and sumac are banned outright at any height.

Key details: Weed height limit: 12 inches (rank weeds). Garden exemption: Tended food-crop gardens exempt. Noxious plants banned: Poison ivy, oak, sumac: any height. Notice period: 10 days to abate. Enforcer: Dir. of Neighborhood Enhancement.

Notice to cut/remove given by mail; 10 days to comply or request a hearing. Unabated nuisances get City-contracted removal billed to the owner as a lien on the property, plus Municipal Court prosecution: each day of continued violation is a separate offense.

The Bottom Line

Oklahoma City's invasive plant rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Oklahoma City is broadly strict or permissive.
