Denton, TX Landscaping Rules: Weed Ordinances (2026)

Section 17-40 of the Denton Code of Ordinances governs weeds under the broader property maintenance chapter. The code does not distinguish between grass and weeds for height purposes: both must remain below 12 inches on improved lots and 18 inches on unimproved lots. Noxious weeds, poison ivy, ragweed, and other vegetation that creates a public health hazard may be cited regardless of height. Community Improvement Services enforces weed violations through the same process as grass height: a written notice providing 10 days to abate, followed by city-contracted abatement and a property lien for costs if the owner fails to comply. Vacant lot owners are particularly affected, as unattended lots in Dentons warm, humid climate can grow dense weed cover rapidly during the April-through-October growing season. The city encourages residents to report weed violations through the Denton 311 portal. Properties with repeated violations may be placed on a proactive inspection list for the duration of the growing season.
