Keller Landscaping Rules: Grass Height Limits Rules (2026)

Keller maintains strict property maintenance standards consistent with its affluent DFW suburban character. Under the city property maintenance code and nuisance chapter, grass, weeds, and rank vegetation may not exceed 12 inches in height on any parcel including improved residential lots, commercial properties, and undeveloped tracts. The requirement extends to the parkway strip between the sidewalk and curb and to alley easements adjacent to the property line. Code Enforcement inspectors identify violations through routine drives, aerial imagery, and citizen complaints. Once a notice of violation is issued, the owner typically has 10 days to bring the property into compliance. If the owner fails to act, Keller contracts mowing crews, performs the work, and assesses the cost plus an administrative fee against the property. The charge attaches as a municipal lien filed at the Tarrant County recorder and must be paid to clear title at sale. Repeat offenders within a 12-month period can be cited without a new notice. HOAs in nearly every Keller subdivision impose stricter standards, often requiring grass be kept below 6 inches, with fines layered on top of city enforcement. Vacant lot owners receive particular attention during drought periods when dry vegetation poses fire risk.
