Summary

St. Petersburg caps grass and weeds at a maximum overall height of 10 inches under City Code § 16.40.060.3.1.D, with ground cover plant material allowed up to 24 inches. The Planning & Economic Development Department (POD) enforces the limit through a written notice-of-violation process, and the City can clear an overgrown lot itself and lien the property for the cost.

Sod (including turf and turfgrass) or other herbaceous growth other than ground cover species shall be maintained at a maximum overall height of ten inches or less; ground cover plant material shall be maintained at an overall height not to exceed 24 inches. Property designated as a preservation area shall not be required to meet these standards.

Full Breakdown

D makes the property owner of record and any occupant jointly responsible for keeping sod, turf, turfgrass and other herbaceous growth trimmed to 10 inches or less, and ground cover plant material to 24 inches or less, on the lot and in the abutting right-of-way. Preservation-area parcels are exempt. Owners who instead maintain a documented Florida-Friendly Landscaping™ or wildlife-habitat management plan, addressing soil amendment, limiting sod to active-use areas, efficient irrigation, mulch use and ongoing maintenance, can keep vegetation outside the height ranges without violating the section.

4. When POD finds a violation, it mails and posts a written Notice of Violation giving the owner a deadline to cut the growth. The owner has 10 calendar days to file a written appeal with the City Clerk (5 days for a repeat violation, the same violation within the prior 12 months under the same ownership), heard informally by a hearing officer whose decision is final. If the owner neither corrects the condition nor appeals, POD may enter the property, including fenced yards, to cut and clear the vegetation itself.

The City then bills its labor and administrative costs, including the Chapter 12 lien recording fee, as a special assessment lien on the property; unpaid principal draws 8% interest for the first year after confirmation and 12% thereafter, and the lien can be foreclosed like a mortgage under Florida Statutes Chapter 702. The section was most recently amended by Ordinance No. 611-H, § 24, adopted July 10, 2025.

Violations & Fines

Failure to keep sod/turf under 10 inches or ground cover under 24 inches is a code violation subject to the Notice of Violation and lot-clearing procedure. Uncorrected violations let POD mow or clear the lot and bill the owner via a special-assessment lien bearing 8% interest, rising to 12% after one year; the lien is enforceable like a mortgage foreclosure.

Frequently Asked Questions

How tall can grass legally grow in St. Petersburg before it's a violation?
Sod, turf and similar herbaceous growth must be kept at 10 inches or less; ground cover plant species get a taller allowance of 24 inches under City Code § 16.40.060.3.1.D.
Can I let my lawn grow taller if I'm doing Florida-Friendly landscaping?
Yes: property owners with a documented Florida-Friendly Landscaping™ or wildlife-habitat management plan covering soil, irrigation, mulch and species selection are exempt from the standard height limits.
What happens if I ignore a grass-height notice of violation?
POD can enter the property to cut the vegetation and bill the cost, plus administrative fees, as a special assessment lien against the property, with interest accruing at 8% to 12% annually.
