The pattern
Florida's preemption regime is a sequence of single-surface closures. Each statute names one thing the local government may no longer control, and stops there.
| Statute | Surface preempted | What it leaves open |
|---|---|---|
| Live Local (SB 102 → SB 1730 → HB 1389) | Density, height, floor-area ratio below the July 2023 maximum | Open space, buffers, site configuration |
| SB 180 (Ch 2025-190) | Any code "more restrictive or burdensome" adopted after August 2024 | Code at or below the August 2024 line |
| §163.3202 Fla. Stat. | Building-design elements on single- and two-family homes | How much land stays open, where it clusters, wetland buffers |
| HB 927 (Ch 2026-64) | Plan review through a state-mandated contractor registry | Recordable infrastructure and maintenance commitments |
| §509.102 Fla. Stat. | Mobile-food-vending licensing | Setback, spacing, and siting standards |
The migration is the response to that geometry. A city that loses one surface re-anchors its leverage on the surface next to it. The durable defensive instruments are the ones operating on un-preempted ground: land-disposition standards and recorded contracts.
Three exhibits, three registers
The June 2026 cycle surfaced three independent cities running the same structural move through three different mechanisms — the cross-register reach is what lifts this from a single tactic to a pattern.
Altamonte Springs ran the move on a single June 2, 2026 packet. Ordinance 1844-26 stands up the qualified-contractor registry HB 927 mandates — the city complying with the state's privatization of the review surface. Ordinance 1841-26, drafted by Chief Planner Jacob Lujan, codifies when a recordable developer's agreement is required, defining the infrastructure, transportation, mitigation, and maintenance commitments that must be captured in an instrument running with the land. As the state loosens the review surface, the city hardens the contract surface. A recorded agreement is far harder to preempt than a discretionary approval. Lake County ran the move across two meetings of the same Planning & Zoning Board. On May 6, 2026 it stripped design standards from the Haines Creek PUD — minimum home size dropped from 1,500 to 1,200 square feet, roof-pitch and material rules removed — under §163.3202's building-design preemption. On June 3, 2026 it sharpened the Rural Conservation Subdivision open-space mandate to a 35%-to-90% range, with 90% required in the Green Swamp Core, adding cemetery, dark-sky, low-impact-development, and tree provisions. The lesson is legible in the code itself: §163.3202 preempts the form of the house; no current statute preempts how much land must stay open, where the development clusters, or where the wetland buffers fall. Maitland ran the move on the protected-use dimension. Its SB 954 recovery-residence ordinance (LDC 5.16, adopted 4-0 March 5, 2026) routes the federally protected use through administrative staff review — the Director decides, not the board — while reserving life-safety, parking, and property-maintenance enforcement. The city complies on the dimension federal fair-housing law protects and holds on the dimensions it does not. This consistently lands at the lowest-visibility surface: Clermont's parallel Chapter 125 article and Maitland's LDC 5.16 both route the decision to a staff director.Two further exhibits extend the geometry into the corridor's newest pressure. Clermont's Ordinance 2026-014 (June 2) moves mobile-food-dispensing vehicles out of the CUP system under §509.102 licensing preemption, then re-anchors local control on the un-preempted siting surface — a 100-foot setback from homes, 100 feet from competing restaurants and trucks, a one-truck-per-site cap. Minneola's Ordinance 2026-05 (June 1) and Winter Garden's Ordinance 26-16 (May 4) condition data-center resource draw — water and power ceilings — through the rejection authority SB 484 explicitly preserves for local governments, the resource-draw surface a closed use-class surface cannot reach.
How the pattern reads
The migrations are not improvised. They follow a structural logic the most professionalized cities have learned to operate inside.
Each preemption is single-surface, not total. A statute closes the specific surface its sponsors named and leaves the rest of the local toolkit intact. The migration reads the statute's edges and moves to the nearest open surface — the move is defensible precisely because the state has not legislated against it.
Land-disposition standards are the most durable surface. Open-space ratios, clustering requirements, buffers, and density-per-acre survive every current statute. Lake County's pivot from house-form rules to a 90% Green Swamp open-space floor is the clearest exhibit — it controls the development's footprint without touching a single design element the state preempted.
Recorded contracts are the second durable surface. A developer's agreement running with the land binds in a way a discretionary approval does not. As HB 927 routes review through a state registry, Altamonte's contract codification re-establishes a friction surface the state cannot easily preempt.
The migration consolidates at the lowest-visibility surface. Maitland and Clermont both route the protected use to a staff director rather than a board hearing. The protected-dimension compliance is visible; the reserved enforcement authority sits in administrative procedure. Comply where the statute compels, hold where it does not, and place the hold where it draws the least contest.
The move is statute-aware, not market-anticipating. The data-center exhibits exercise the rejection and reclaimed-water authority SB 484 preserved on July 1, 2026 — the cities are operating a state-granted lever, not anticipating a market. The migration tracks the legislature's own surface map.
What's next for this pattern
The Pattern Atlas will track:
- Whether the migration recurs as a deliberate two-move packet in other high-capacity cities — the Altamonte review-to-contract pairing is the cleanest template, and Lake Mary and Maitland run the same legislative-mode posture
- Whether thin-staffed cities adopt the open-space and recorded-contract surfaces, or take state mandates as routine housekeeping — the capacity gap is the variable that sorts migration from passive compliance (Davenport and Mascotte at the passive pole, Altamonte at the migrating pole)
- Whether SB 180's October 2027 moratorium expiration changes the calculus — the migration is being run into an active, fully-enforceable freeze (the session law runs to June 30, 2028), so the un-preempted surfaces carry the cities' weight until then; see watch
sb-180-sunset-2028 - Whether the qualified-contractor registries cities build under HB 927 gate on local-familiarity or settle for minimal compliance — the registry is the review surface the state loosened; see watch
hb-927-registry-adoption - Whether a future statute closes one of the currently durable surfaces — a preemption of land-disposition standards or recorded agreements would collapse the migration's destination and force the next move
Related patterns and entities
This pattern composes with the corpus's broader regulatory-architecture readings:
- The Grandfather Window (pattern + brief) — SB 180 sorts the corridor's codes by adoption date; the Surface Migration is what cities do once they accept the freeze runs to October 2027 rather than racing a sunset. The two patterns share a clock: every migrated surface is a surface the city judged safe from the August 2024 line.
- Recovery Residences Regulatory Pre-coding (pattern) — the first documented migration in the corpus, before the meta-pattern was named. Maitland is the fourth city to route the SB 954 use to administrative review while reserving enforcement, generalizing the precoding move into the broader Surface Migration mechanism.
- The Water Gate (pattern) — the data-center precoding the Surface Migration extends to a market-driven use class. The Water Gate names the resource-draw exclusion; the Surface Migration names the structural move that produces it — conditioning a use through the resource-draw surface SB 484 preserved.
- The Quiet Revolution on Highway 27 (pattern + brief) — the corridor's municipal regulatory rebuild. The Surface Migration is the rebuild's defensive grammar: as the state forecloses surfaces, the cities relocate their leverage to the ones that remain.
For attorneys structuring entitlement strategy, the practical reading: a preempted surface is preempted; the adjacent surface is where the city's leverage moved. Read the open-space ratio, the buffer, the recorded-agreement trigger — not the surface the statute closed. For city counsel and planners, the durable instruments are the ones the legislature has not named. Land-disposition standards and recorded contracts carry the weight that discretionary review and building-design control no longer can.
