Tualatin caps lawn grass at ten inches under TMC 6-4-090 (noxious vegetation) and reinforces it in TMC 6-13-040 for rental housing. Enforcement runs March 1 through October 31, the prime growing season for pollen and seed production.
Turf-grass height in Tualatin is regulated by two parallel sections. TMC 6-4-090 (Noxious Vegetation), within Chapter 6-04 Nuisance Animals/Vegetation, prohibits noxious vegetation on any property between March 1 and October 31, including grasses or weeds taller than 10 inches or above the height at which pollen forms and seeds set. TMC 6-13-040 (Rental Housing Code) separately requires every landlord to keep lawns trimmed to a height of not more than 10 inches, excluding ornamental grasses used in landscaping. The city's Code Compliance team investigates tall-grass complaints, issues notice-of-violation letters, and can authorize abatement at the owner's cost if the property is not brought into compliance. Native habitat areas designated for wildlife are exempt from the noxious-vegetation classification under TMC 6-04-060(3).
Lawn grass over 10 inches between March 1 and October 31 is a code violation. The city issues a written notice; if grass is not cut, Tualatin may abate, bill the owner, lien for unpaid abatement, and issue fines.
