Summary

Unincorporated Palm Beach County caps grass and weeds at 7 inches on developed lots and 18 inches on vacant lots, and bans all noxious weeds outright under the county's Property Maintenance Code.

City-specific rules exist: Jupiter, West Palm Beach, Boynton Beach, Delray Beach, and Boca Raton have their own weed ordinances rules that differ from Palm Beach County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

(c)Excessive growth of grass, weeds and low-growing vegetation.(1)Grass, weeds and low-growing vegetation shall be maintained as follows: ... Developed or Partially Developed—Residential and Non-Residential | One-half acre or less | 7 inches on the entire lot. ... (3)All noxious weeds are prohibited. Noxious weeds shall not include cultivated flowers and gardens or native vegetation.

Full Breakdown

Chapter 14, Article I of the county's Property Maintenance Code (Sec. 14-32(c)) sets maximum vegetation heights for unincorporated Palm Beach County. Developed lots of a half-acre or less must keep grass and weeds under 7 inches; larger developed lots only need that height held on a 25-foot strip along any side bordering a developed lot. Vacant lots follow the same pattern at an 18-inch cap. Separately, subsection (c)(3) bans all noxious weeds outright, though cultivated flowers, gardens, and native vegetation are exempt. This chapter governs unincorporated areas only. West Palm Beach, Boca Raton, Delray Beach, Boynton Beach, and Jupiter enforce their own municipal codes, not this one.

Violations & Fines

Code Enforcement Division inspectors issue a notice of violation; uncorrected mowing or noxious-weed violations go before the county's Code Enforcement Board, which can impose daily fines that attach as a lien on the property.

Frequently Asked Questions

No. Chapter 14 governs only unincorporated Palm Beach County; West Palm Beach, Boca Raton, Delray Beach, Boynton Beach, Jupiter, and the county's other municipalities enforce their own codes.
How tall can weeds get before it's a violation?
On a developed lot of a half-acre or less, grass and weeds must stay under 7 inches; vacant lots of that size get an 18-inch cap.
