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, with a 13.1% hit at the 2027 $150,000 step. 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 is notably larger than the out-of-state share, which means the rental market here is predominantly a local, Florida-owned one rather than an absentee-ownership story. Among ranked Florida cities, Palmetto Bay sits at 157 of 404 by exposure level.

Land-use composition

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

A few figures stand out in this table. The single industrial parcel in the city is entirely out-of-state owned by both parcel count and value. The Govt/Public category shows 32.9% of its value out-of-state owned by parcel, which reflects the nature of government and institutional holdings rather than a residential absentee pattern. The Multifamily category shows 18.1% of its value out-of-state owned despite less than 1% of its parcels being out-of-state, indicating that the out-of-state-owned multifamily parcels, though few, carry disproportionate value.

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 calculated 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 the property to market value. Transaction velocity matters more to non-homestead base growth under the new cap than it did under the old one.

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 to every homestead. 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 recruiting and zoning for a commercial and employment spine. Converting a share of future growth from rooftops to taxable commercial square footage is the most direct path to deepening the non-homestead base, because commercial property carries no homestead exemption. A neighborhood-serving retail node, a small office or medical-office cluster, or a light-flex business park on an existing arterial would each add value in a category the amendment does not touch.
• Multifamily rental is the second lever. Apartments pay full freight under the amendment, and at 3.4% of total value, the rental base is thin. Allowing well-sited rental near jobs and transit adds non-homestead value while also addressing workforce housing demand. The Florida-owned character of the existing rental market suggests local appetite for this type of investment is already present.
• Any commercial and rental growth should be concentrated along an existing arterial or corridor rather than scattered across the city. A real non-homestead spine in one location is far more durable than thin commercial spread everywhere. Directing new commercial square footage and well-sited rental to that corridor gives the city a legible, investable address rather than a diffuse pattern that never reaches critical mass.
• Palmetto Bay should also prioritize commercial and industrial parcels for any future municipal growth rather than approving more subdivisions. Each new subdivision adds homestead value the amendment will exempt while adding service demand the millage must cover. The one industrial parcel in the city represents a category that is almost entirely absent from the base; protecting and, where feasible, expanding that footprint matters.
• Finally, any existing employment anchor — a hospital, college, distribution facility, or government office — should be protected and, where possible, intensified. These are the non-homestead taxpayers already in place, and they are the foundation any diversification strategy builds on.

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 trap that created the exposure in the first place.

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 at the $150,000 step, followed by the 2028 roll at the full $250,000 phase-in. When the 2026 and later rolls are certified, this 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 because an out-of-state owner using an in-state mailing address or LLC counts as Florida-owned. It does not prove where an owner actually lives. This read is a land-use-composition starting point, not a full fiscal, economic, or legal analysis.
