Omaha, NE Landscaping Rules: Weed Ordinances (2026)

City code makes it unlawful for an owner, agent, or occupant to permit noxious weeds, grass, or other nuisance vegetation to reach 12 inches or more in height on any lot, including the abutting half of the right-of-way, streets, and alleys. Owners must cut such growth as close to the ground as possible and keep it from exceeding 12 inches, raking and removing the cuttings. The city publishes an annual notice each March, and if an owner doesn't comply after notice, the city can cut or spray the growth itself and specially assess the cost against the property. Narrow exceptions exist for native plants in wooded areas, along creeks, on steep slopes over 45 degrees, or on larger parcels used for conservation or golf courses: residential land does not qualify for these exceptions.
