First Coast Outdoor Care
Last Updated: July 2026
Most routine landscaping in Jacksonville does not need a permit. Planting, mulching, sod, flower beds, and ordinary lawn care are permit-free. A permit comes into play when the work turns structural or touches a regulated system: building or altering a structure, installing or replacing an irrigation system, removing a protected tree, or clearing and regrading a site. The City of Jacksonville’s Building Inspection Division is the authority for all of it, and as of this writing the city requires online permit submission for all permit types through its JaxEPICS system. Below is how the rules break down by project type. This is general guidance from a local landscaping company, not legal advice. Always confirm your specific project with the Building Inspection Division at (904) 255-8500, Option 4.
Retaining Walls
Jacksonville’s residential permit rules require a permit any time you construct, enlarge, alter, repair, move, or demolish a structure, and a retaining wall that holds back soil is a structure. The city’s published pages do not state a height threshold below which retaining walls are exempt, so check any retaining wall project with the Building Inspection Division. Walls holding back significant grade, sitting near a property line, or affecting drainage are the most likely to need engineering review.
Fences
Fence height in Jacksonville is governed by zoning. Per the city’s Zoning FAQs, the maximum fence height is 4 feet within the front yard setback, and toward the rear of the property a fence can be up to 8 feet. Corner lots must keep a visibility triangle clear for traffic safety. If you want to exceed the standard heights, you need an administrative deviation. Fence rules vary by zoning district, so confirm your lot’s district with the Zoning Section before ordering materials.
Patios, Decks, and Hardscape
Good news first: the city’s permit FAQs specifically list patio slabs as work that does not require a permit. Simple paver patios and walkways at grade generally fall in the same low-risk category. The line gets crossed when the project becomes a structure: patio covers and room additions are explicitly listed as permit-required, and an elevated deck is a structure under the construct-or-alter rule on the residential permits page. Also note that a Notice of Commencement is required on most jobs over $5,000, and permits are valid for 180 days.
Irrigation and Backflow Prevention
Irrigation is one of the most commonly missed permits in Jacksonville. The city’s permit FAQs list irrigation system work among the items that require a permit, including replacements. On top of the permit, JEA’s residential backflow requirements apply: in-ground irrigation systems have needed a backflow preventer since 1990 under the Florida Building Code, whether the system runs off your regular water service, a well, or reclaimed water. The state requires homeowners to have backflow preventers tested every two years by a certified tester, and JEA runs a checkup program to keep homeowners compliant.
Tree Removal
Jacksonville protects trees by ordinance. The city’s Urban Forestry FAQ confirms that healthy trees are protected under the City’s Tree Ordinance and that tree removal permits run through the Building Inspection Division at the applicant’s expense. Removals of protected trees carry mitigation obligations, tracked through the city’s tree mitigation system. The exact size and species thresholds that make a tree “protected” were not published on the pages we verified, so before cutting anything larger than a small ornamental, check with the Building Inspection Division. Fines for unpermitted removal can be severe.
Grading and Drainage
Changing how water moves across your lot is regulated. Per the city’s site clearing permit guidance, site clearing permits are issued only after all landscape and drainage issues are addressed, and applications must include a tree survey of protected trees and engineering plans showing grade changes. Larger projects can also trigger a St. Johns River Water Management District permit, which that guidance notes applies at thresholds such as 4,000 square feet or more of new impervious surface. For typical residential regrading, ask the Building Inspection Division whether your scope needs review before the first shovel hits dirt.
FAQ
Do I need a permit to plant trees, shrubs, or sod in Jacksonville?
No. Ordinary planting and lawn work are not on the city’s permit-required list. Permits apply to structures, systems, protected-tree removal, and site clearing.
Do I need a permit to replace an existing sprinkler system?
Yes. The city’s permit FAQs list irrigation system work, including replacement, as permit-required, and JEA backflow rules still apply to the rebuilt system.
Can I pull my own permits as a homeowner?
The city maintains a homeowner permitting option through the Building Inspection Division, and all permit applications now go through the online JaxEPICS system. Call (904) 255-8500, Option 4, to confirm eligibility for your project.

*Method note: thresholds and requirements above were verified against official City of Jacksonville (jacksonville.gov), coj.net, and JEA pages fetched in July 2026. Where an exact numeric threshold was not published on a page we could verify, we say so and point you to the city instead of guessing.*
