St. Johns County Moves Toward an Injunction Against Florida's Agricultural Enclave Law

St. Johns County is preparing to ask a court to block a new Florida law that lets landowners bypass the county's normal development review, a strategy aimed at slowing a proposal that could add thousands of homes near Ponte Vedra Beach. County commissioners have been working through the mechanics of seeking an injunction against Senate Bill 686, the agricultural enclave law that took effect July 1, after an August 4 meeting at which the county attorney laid out the steps required to bring a challenge.

The immediate trigger is a certification application covering 4,462 acres owned by the Davis family, founders of the Winn-Dixie grocery chain, in Ponte Vedra Beach. The filing requests a density of one residential unit per gross acre, which would permit as many as 4,462 homes on land that sits near Nocatee, one of the fastest-growing master-planned communities in the country. The Board of County Commissioners considered the application on September 1 and did not reach consensus on whether to approve or deny it.

The dispute is a clean illustration of a fight running through fast-growing Florida counties: who decides where houses get built. For decades that answer has been the county commission, operating through comprehensive plan amendments and rezonings that require public hearings. SB 686 creates a path around that process for a specific category of land.

How the agricultural enclave law works

Signed by Governor Ron DeSantis and effective July 1, SB 686 establishes a streamlined review for residential development on land certified as an agricultural enclave. A parcel qualifies if it is unincorporated, undeveloped, held under single ownership, surrounded on at least 75 percent of its perimeter by existing development, and located in a county with fewer than 1.75 million residents.

The population threshold is doing significant work in that definition. It excludes Miami-Dade, Broward and a small number of other large counties while capturing most of the rest of Florida, including the suburban counties absorbing the bulk of the state's growth. St. Johns County, wedged between Jacksonville and St. Augustine, is squarely inside it.

The 75 percent surrounded requirement is the provision that defines an enclave conceptually. The law's premise is that farmland already ringed by subdivisions is functionally suburban land, that it is unlikely to remain in agriculture, and that requiring a full comprehensive plan amendment to acknowledge that reality adds cost and delay without changing the outcome.

Landowners meeting the criteria may apply directly for agricultural enclave certification, skipping the standard comprehensive plan amendment and rezoning sequence. That is the compression the law delivers, and it is what county governments object to, because the comprehensive plan process is where a county negotiates road capacity, school sites, drainage and utility extensions.

Why St. Johns County is the flashpoint

St. Johns has been among the fastest-growing counties in Florida for more than a decade, and its growth has been concentrated in exactly the geography the law addresses. Nocatee alone has transformed a large stretch of former timber and agricultural land into a community of tens of thousands, and the parcels adjacent to it fit the surrounded-by-development test almost by definition.

The Davis family application is the largest but not the only one. A separate filing seeks certification for roughly 200 acres in the county, and an eighth enclave application was filed in early August. That volume is the county's central complaint: the law has produced not one project but a queue, and the county's ability to plan infrastructure across that queue depends on a process the law removes.

Road capacity is the most concrete pressure point. County Road 210 and the corridors feeding Nocatee already carry traffic well beyond their original design assumptions, and school capacity in the northern part of the county has required repeated adjustment. Adding several thousand homes without the concurrency negotiations that normally accompany a rezoning shifts those costs onto the county's general budget.

Water and wastewater present a similar problem. Extending utility service to a large new development is a capital expense that counties typically negotiate with developers during entitlement. A certification path that shortcuts entitlement also shortcuts that negotiation.

The county's legal options

County Attorney Rich Komando outlined a sequence for the commission in August: identify the legal basis for an injunction, determine whether the county can show sufficient harm to justify court intervention, and evaluate the cost of litigation. Each of those is a real hurdle rather than a formality.

Florida counties are creatures of the state, and the Legislature's authority to preempt local regulation is broad. Successful local challenges to state preemption in Florida have generally turned on specific constitutional provisions rather than on a general argument that the state has intruded on local prerogatives. Identifying which provision SB 686 violates is the threshold question.

Standing and harm are the second hurdle. A county seeking an injunction must show concrete injury rather than a policy disagreement, and it must show that injury is imminent enough to warrant blocking a statute before it operates. The pending applications help the county on that point, because they convert an abstract objection into a specific set of approaching decisions.

Cost is the third. Litigation against the state is expensive and slow, and a county that loses may face a long appellate process during which certifications continue. Commissioners weighing the injunction strategy are weighing it against the possibility of spending public money and ending up where they started.

The statewide stakes

St. Johns is the county moving first, but it is not the only one exposed. The agricultural enclave law reaches most Florida counties, and land that satisfies the surrounded-by-development test exists across the state's growth corridors, from Pasco and Polk counties through Lake, Osceola and Manatee. A ruling on SB 686 would set the terms for all of them.

Development interests view the law as a response to a real problem. Florida's housing affordability pressure is severe, driven substantially by supply constraints, and entitlement processes that take years add carrying cost that ends up in the price of a house. From that perspective, streamlining approvals for land already surrounded by subdivisions is among the lower-cost supply interventions available.

Local government and land conservation groups counter that the law solves a cost problem by transferring it. Infrastructure for new development gets paid for regardless, and removing the negotiation stage does not remove the road, the school or the wastewater plant. It relocates the bill from the developer to the county tax base.

Agricultural land loss is the third argument, and it is one Florida has been having for fifty years. The state has lost farmland at a steady rate as development pushed inland, and the enclave framework, by design, accelerates conversion of the parcels closest to existing suburbs.

What happens to the Davis application

The commission's failure to reach consensus on September 1 leaves the 4,462-acre application unresolved rather than denied. How the law treats an application that a county neither approves nor denies within its review window is one of the questions a legal challenge would likely put in front of a judge.

The requested density of one unit per gross acre is relatively low by suburban standards, and the eventual built product on a parcel that size would depend on internal design, wetlands, conservation set-asides and stormwater requirements. The 4,462-home figure represents a ceiling rather than a plan.

Wetlands and environmental permitting operate independently of the enclave certification. A certified enclave still requires state and federal environmental permits, and northeastern St. Johns County contains substantial wetland systems that connect to the Guana River and the Intracoastal Waterway. Those permits are a separate and often lengthy process.

How Florida got here

The agricultural enclave concept did not appear in Florida law for the first time in 2026. The state has had an agricultural enclave definition on the books since the 2000s, used primarily to allow certain surrounded farm parcels to be brought into a comprehensive plan through a simplified amendment. What SB 686 changed was the degree of local discretion left in the process.

That change came out of a broader legislative posture toward housing supply. Florida lawmakers have spent several sessions attempting to increase the pace of residential construction, most visibly through the Live Local Act, which preempted local zoning and height restrictions for qualifying affordable housing developments in commercial and industrial zones. The enclave law extends the same instinct to a different category of land.

The results of that approach have been uneven and heavily dependent on local circumstance. Live Local produced a wave of proposals in some Florida cities and almost none in others, largely because the underlying economics of a project matter more than the entitlement path. The same is likely to prove true of enclave certifications, which is one reason the eight applications filed in St. Johns County stand out.

Counties have responded to the preemption trend by looking for authority the Legislature has not touched. Impact fees, concurrency requirements, utility service boundaries and environmental permitting all remain areas of local leverage, and county attorneys across Florida have been mapping which of them survive under each new statute.

That is the strategic backdrop to the St. Johns litigation question. A county that cannot stop a certification may still be able to shape what gets built through the tools the Legislature left in place, and the injunction strategy runs parallel to that quieter work rather than replacing it.

What it means for residents

For St. Johns County residents, the near-term effect is uncertainty rather than construction. Certification is an early step, and even an approved enclave would face years of site planning, permitting and vertical construction before homes are occupied. The traffic and school effects residents are worried about are not imminent.

For homebuyers across northeast Florida, the law points in the direction of more supply in the medium term, which is the outcome its supporters intend. Whether that translates into lower prices depends on interest rates and construction costs at least as much as on entitlement policy.

For county taxpayers, the fiscal question is the one to watch. If large developments proceed without the infrastructure commitments that normally accompany rezoning, the capital costs land on the county's budget, which means either impact fee increases, millage adjustments or deferred maintenance elsewhere.

What's next

The commission's decision on whether to actually file for an injunction, and in which court, is the next concrete step. A filing would likely draw intervention from landowners with pending applications and possibly from the state, given that the challenge targets a statute rather than a local decision.

Other Florida counties will be watching the outcome closely, and a favorable early ruling for St. Johns would likely produce parallel filings elsewhere. Absent that, the enclave application queue in St. Johns County continues to move under the law as written.
