HJR 1 Homestead-Exemption Tax-Base Exposure

Miami-Dade County . 2025 final assessment roll

Snapshot

The Palmetto Bay read

Palmetto Bay fits the Bedroom Residential Monoculture archetype. The base is owner-occupied single-family housing at moderate value with thin commercial, industrial, or rental property — this is the maximum-exposure profile, because almost every dollar of value is the exact kind of property the amendment exempts. Strip the homesteads and little taxable base remains. At full phase-in in 2028, 25.4% of Palmetto Bay’s non-school taxable base is exposed to the $250,000 exemption; the 2027 step lands at 13.1%. The driver is straightforward: a high homestead share combined with a low commercial share means the exemption lands on nearly the whole base at once.

Of 9,150 residential housing units, 68.7% are owner-occupied, 3.5% are owned by out-of-state owners, and 27.8% are non-homestead but Florida-owned. The Florida-owned non-homestead share — local landlords and in-state second-home owners — is the larger non-homestead pool here, not absentee outside ownership. Among Florida cities, Palmetto Bay ranks 157 of 404 by HJR 1 exposure.

Land-use composition

Share of taxable value by category, Palmetto Bay, 2025 roll:

Residential value dominates at 81.1% of the roll, with Commercial at 8.7% and Multifamily at 3.4% — together the non-homestead-eligible categories are thin. The single Industrial parcel (100% out-of-state by both parcels and value) is a notable outlier but represents only 0.1% of total value. The Govt/Public category shows 32.9% of its value out-of-state owned by parcel count, which reflects the nature of that bucket rather than a residential ownership signal.

What the exposure band means

Moderate exposure. A meaningful but absorbable hit. The place has some non-homestead base to lean on. Mitigation is about steering future growth, not emergency response.

Looking ahead

Neither of the following changes the exposure figure above; both shape how Palmetto Bay grows its base after the amendment takes effect.

First, beginning January 1, 2027, the annual assessment-increase cap on non-homestead property drops from 10% to 5%, covering commercial and industrial real property and small residential rentals of nine units or fewer. Because a capped property’s assessed value can rise only 5% per year, the main engine of base growth in these categories becomes transactions — a sale or change of control resets value to market — so transaction velocity matters more to non-homestead base growth than it did under the old cap.

Second, new Florida residents who did not maintain a Florida permanent residence as of December 31, 2026 phase into the larger exemption over five years rather than receiving it immediately. This residency ramp cannot be read from the assessment roll, so all exposure figures here assume full application of the exemption. Near-term exposure could run slightly lower than modeled in places with many recent arrivals still inside their five-year window.

Where the opportunity is

These recommendations are based solely on the tax roll’s land-use composition. They do not account for whether local land development regulations and zoning permit any of these uses, whether there is local obstruction, or the political dynamics that typically decide what actually gets approved. This is a starting point for a conversation, not a development plan.

• With Commercial at only 8.7% of total value, the single highest-leverage move for Palmetto Bay is building a commercial and employment spine. Converting a share of future growth from rooftops to taxable commercial square footage — a neighborhood-serving retail node, a small office or medical-office cluster, or a light-flex business park on an arterial — adds non-homestead value the amendment does not touch. This is the move that changes the structural composition of the base over time.
• Multifamily rental is the second lever. At 3.4% of total value across 111 parcels, apartments are underrepresented relative to the city’s residential scale. Rental property pays full freight under the amendment, and well-sited rental near jobs and transit adds non-homestead taxable value while also addressing workforce housing demand. The 27.8% Florida-owned non-homestead share signals that a local rental market already exists; deepening it in the right locations builds on that foundation.
• Rather than scattering commercial and rental growth, concentrating it along an existing arterial or corridor lets a real non-homestead spine form in one place instead of staying thin everywhere. A corridor strategy directs new commercial square footage and well-sited rental to a single location where the cumulative value can actually register on the roll.
• Any existing employment anchor — a hospital, medical office, government facility, or institutional use — is already a non-homestead taxpayer in place. Protecting and intensifying those anchors is lower-risk than recruiting new ones from scratch, and it deepens the base without adding homestead value.
• Finally, if the city’s footprint ever expands, prioritizing commercial and industrial parcels over additional single-family subdivisions ensures that any growth deepens the non-homestead base rather than the monoculture.

Watch-out: do not solve a revenue hole by approving more single-family subdivisions. Each one adds homestead value the amendment will exempt while adding service demand the millage must cover. That is the structural trap that created the exposure in the first place, and more of the same deepens it.

Source and scope

All figures are drawn from the Florida Department of Revenue 2025 final assessment roll, the most recent certified roll in the state’s possession. The roll is used here as a structural proxy for tax-base composition, not as a dollar forecast for any specific budget year. HJR 1 / CS-HJR 1F is on the November 2026 ballot; the 2026 roll is the assessment roll in place when voters decide. If the amendment passes, the first roll affected is the 2027 roll (the $150,000 step), with full $250,000 phase-in on the 2028 roll. When the 2026 and later rolls are certified, the analysis re-runs on the new data.

Ownership shares are measured on a residential-unit basis. The out-of-state ownership figure is a mailing-address proxy: it counts residential units whose owner’s mailing-address state in the roll is a non-Florida state or country. It undercounts true outside ownership — an out-of-state owner using an in-state LLC address counts as Florida — and it does not prove where any individual owner actually lives. This is a land-use-composition starting point, not a full fiscal, economic, or legal analysis.
