Provo, UT Landscaping Rules: Grass Height Limits (2026)

Provo does not set a single numeric lawn-height limit but controls tall grass and weeds through nuisance and landscaping provisions. Section 7.01.020 of the Provo City Code declares it a public nuisance for a property owner or occupant to allow noxious weeds on vacant lots or other property, along public sidewalks or the outer edge of any public street, or weeds elsewhere that create an unreasonable fire hazard (subsection 6), as well as dead, decayed, diseased, or hazardous trees, weeds, hedges, and overgrown or uncultivated vegetation that is in a hazardous condition, obstructs pedestrian or vehicular traffic, or is likely to harbor rats, vermin, or other pests (subsection 12). For developed and landscaped property, Section 15.20.070 requires landscaping to be kept fertilized, mowed, trimmed, edged, mulched, and free from weeds. In the parkway (park strip) between curb and sidewalk, Section 15.20.120 caps the mature height of vegetative materials (excluding trees) at twenty-four (24) inches and requires the abutting owner to keep the parkway weed-free. Together these create an enforceable expectation that grass and weeds be mowed and maintained, with the park-strip 24-inch maximum being the clearest numeric standard. The state-law backstop is the Utah Noxious Weed Act, Utah Code Title 4, Chapter 17.
