Lake Mary, Florida

HJR 1 Homestead-Exemption Tax-Base Exposure

Seminole County . 2025 final assessment roll

Snapshot

The Lake Mary read

Lake Mary fits the Commercial / Employment Anchor archetype: real commercial depth — retail, office, medical, or a downtown core — carrying a substantial share of value, and that profile is the most insulated productive configuration a Florida city can hold.

At full $250,000 phase-in in 2028, HJR 1 exposure sits at 20.9%, with the 2027 step landing at 11.7%.

The reason the number is this low is straightforward: commercial property carries no homestead exemption, so every commercial dollar is a dollar the amendment cannot touch, and commercial uses account for 23.7% of Lake Mary’s total just value.

Among ranked Florida cities, Lake Mary sits 234 of 404 by exposure, placing it in the lower-middle tier — meaningfully insulated relative to the state’s most residential places.

Of 8,970 residential housing units, 52.2% are owner-occupied, 26.3% are owned by out-of-state owners, and 21.3% are non-homestead but Florida-owned.

The out-of-state share at 26.3% is notable — approaching but not crossing the 30% threshold — and reflects a meaningful investor and second-home presence in the housing stock.

The Florida-owned non-homestead share at 21.3% points to a local rental market alongside that outside ownership.

Land-use composition

Share of taxable value by category, Lake Mary, 2025 roll:

Two figures in this table deserve attention. Multifamily shows 97.4% of its value owned by out-of-state owners — nearly the entire apartment base in Lake Mary is held by outside capital.

Industrial similarly shows 50.9% of its value in out-of-state hands, and commercial shows 42.8%.

These are ownership patterns that shape how value resets over time, not an exposure problem in themselves, but they are worth tracking as the 5% non-homestead cap takes effect.

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 figures above; both shape how Lake Mary 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 shifts to transactions: a sale or change of control resets the property to market value.

Given that a large share of Lake Mary’s commercial, industrial, and multifamily value is already in out-of-state hands — ownership structures that tend to transact — transaction velocity will matter more to the city’s non-homestead base growth than it did under the old 10% 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 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 the uses described, whether there is local obstruction, or the political dynamics that typically decide what actually gets approved.

• Lake Mary’s commercial base is the asset doing the insulating, and the first priority is defending and deepening it.
• Reinvesting in the commercial corridor — through infill, upper-floor uses, and denser frontage — keeps the non-homestead base growing in the category the amendment cannot reach.
• Intensifying existing commercial nodes rather than allowing them to thin out or convert to residential is the single most direct lever available.
• Adding multifamily near the commercial core serves two purposes: it houses the workforce that sustains the employment anchor, and it adds taxable rental value in a category the amendment does not exempt.
• The multifamily base is currently small at 7.7% of total value, and given that nearly all of it is already in out-of-state ownership, any new rental development adds to a category that is both amendment-insulated and transaction-active under the new 5% cap.
• Recruiting traded-sector employers — logistics, back-office operations, light manufacturing — broadens the commercial base beyond retail and reduces dependence on consumer spending cycles.
• Industrial currently accounts for only 4.1% of total value, and the 28.6% out-of-state parcel ownership in that category suggests existing industrial land is already attractive to outside capital.
• Arterial frontage and any converting or vacant parcels are the natural locations for this kind of expansion.

Watch-out: single-tenant or single-sector dependence is the real risk here, not the amendment.

A concentration of value in a few large commercial owners means that one vacancy, one lease non-renewal, or one ownership transfer at a distressed price can move the needle on the tax base more than the amendment itself.

Monitoring value concentration in the commercial portfolio is the ongoing discipline this archetype requires.

Source and scope

All figures are computed from the Florida Department of Revenue 2025 final assessment roll, the most recent certified roll in the state’s possession.

The roll is used as a structural proxy for Lake Mary’s 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 full $250,000 phase-in.

When the 2026 and later rolls are certified, the analysis re-runs on the new data.

Ownership shares are measured on a residential housing-unit basis.

The out-of-state ownership figure is a mailing-address proxy: it identifies owners whose address on the assessment roll is a non-Florida state or country.

It undercounts true outside ownership — an out-of-state owner using an in-state LLC mailing address counts as Florida — and it does not prove where any individual owner actually lives.

It is the best available structural signal from the roll, not a definitive residency determination.

This read is a land-use-composition starting point.

It is not a comprehensive fiscal, economic, or legal analysis, and it is not a substitute for a full planning or budget review.
