Speculative vs. Build-to-Suit Industrial in Florida: 2026 Developer Strategy

Every industrial developer in Florida faces a fundamental strategic question before breaking ground: do you build spec and bet on the market, or do you secure a tenant commitment first and build to their specifications? The answer shapes financial structure, construction timing, risk-adjusted returns, and ultimately which markets attract which development strategies.

In 2026, Florida's industrial development pipeline reflects a roughly 60/40 split in favor of speculative construction, with meaningful variation by market. Understanding why developers make these choices — and where each strategy tends to win — is essential context for investors, tenants, and anyone tracking the state's industrial supply pipeline.

Defining the Models

Speculative (Spec) Development

In speculative development, a developer acquires land, designs a modern industrial building (typically with vanilla-box specifications that appeal to the broadest tenant universe), and begins construction without a signed lease. The business logic:

• Faster time-to-market: Tenants in tight markets often need space faster than a BTS timeline (18–24 months minimum) allows.
• Development spread: A successfully leased spec building typically trades at a cap rate 50–150 basis points tighter than the development yield, generating a profitable exit.
• Market timing: Developers who start spec projects at the right point in the cycle can deliver into a landlord market with strong pricing power.

The risk is obvious: if the market softens during construction or post-delivery, the developer holds an empty building with carrying costs accumulating.

Build-to-Suit (BTS) Development

In a build-to-suit, a tenant with specific space requirements — a particular clear height, a unique dock configuration, specialty power, cold storage, or a specific location relative to a port or highway — approaches a developer (or the developer approaches them) to negotiate a long-term lease before construction starts. The developer effectively becomes the tenant's real estate partner, tailoring the facility to their operational needs.

Key characteristics:

• Risk transfer: The tenant commits to a 10–20 year lease before the shovel goes in the ground. The developer's lease-up risk is essentially zero.
• Lower development yield: BTS developers typically accept a 25–75 basis point lower spread over construction cost because the certainty of cash flows justifies a more institutional, lower-risk structure.
• Specialty premium: BTS buildings with mission-critical tenant requirements (cold storage, high-cube, data center-adjacent) often achieve rent structures not obtainable in spec buildings.

Risk and Return Profile Comparison

| Factor | Speculative | Build-to-Suit | |---|---|---| | Pre-construction lease | None | Yes (10–20 year) | | Lease-up risk | High | Essentially none | | Development spread potential | 150–300 bps | 75–150 bps | | Construction timeline flexibility | High | Low (tenant-driven) | | Building customization | Vanilla box | Tenant-specific | | Financing difficulty | Higher (lenders require pre-leasing) | Lower (signed lease de-risks) | | Cap rate at sale | Lower (stabilized product) | Slightly higher (long-term, single-tenant) | | Time to stabilized income | 6–24 months post-delivery | Day 1 of tenant occupancy |

Florida's Pipeline: Who's Building What, Where

Miami-Dade: Spec Dominates

Miami-Dade's development market is overwhelmingly speculative — a reflection of both land scarcity and the certainty of absorption. In Doral, Medley, and Hialeah, developers have enough historical data to know that a well-located, 32-foot clear-height industrial building will be leased within 90–180 days of shell completion. The market's sub-4% vacancy makes that assumption defensible.

Prologis and Bridge Industrial are among the most active spec developers in South Florida, delivering smaller-format buildings (50,000–200,000 sq ft) optimized for multi-tenant occupancy. IDI Logistics (now EQT Exeter) has targeted the 200,000–400,000 sq ft range in the Airport West submarket, where e-commerce and logistics tenants compete aggressively for available space.

Foreign capital backing spec development in Miami-Dade is notable — Canadian institutional investors and Latin American family offices have bankrolled several speculative projects in anticipation of strong leasing velocity and favorable exit pricing.

Jacksonville: BTS Gains Ground

Jacksonville's market supports both strategies, but BTS has seen proportionally more activity here than in South Florida. JAXPORT's expansion has attracted large-format industrial users — Amazon, Chewy, Home Depot — that require purpose-built facilities with specific operational configurations.

The Northwest Quadrant and Cecil Commerce Center have been the primary landing zones for BTS activity. Cecil, a former Naval Air Station redeveloped as a logistics park, has attracted multiple BTS tenants drawn by rail access, large contiguous sites, and proximity to I-10.

Spec development remains active in Jacksonville, but developers tend to build in the 100,000–300,000 sq ft range where multi-tenant flexibility reduces single-tenant dependency.

Central Florida / I-4 Corridor: Mixed Strategy

Central Florida sees both strategies compete effectively. The Lakeland market has seen several large BTS projects from national retailers and distributors — Walmart, Dick's Sporting Goods, and several major 3PL operators have signed or completed BTS deals here in the past three years.

At the same time, the I-4 corridor's demand depth makes speculative construction rational for developers with landholdings near major highway interchanges. Eldridge Industries and Link Logistics (Blackstone) have both pursued speculative logistics parks in southwestern Orange County and Osceola County.

Key Florida Developers and Their Strategies

Prologis

The world's largest industrial REIT and one of Florida's most active developers. Prologis's Florida strategy is primarily speculative in Miami-Dade and Tampa, where its land bank and market relationships give it a competitive advantage. The company builds at institutional quality and holds for long-term income, rarely selling individual assets.

IDI Logistics / EQT Exeter

IDI Logistics (acquired by EQT Exeter) is among the most active spec developers in South Florida and the Southeast broadly. Their projects tend to be mid-size (150,000–500,000 sq ft) with modern specifications targeting e-commerce and logistics users.

Eldridge Industries / Link Industrial

Link Industrial, Blackstone's industrial platform, has been active in Central Florida spec development. Their capital base allows them to carry larger speculative positions than most private developers.

Bridge Industrial

Focused on last-mile and infill locations across South Florida, Bridge has carved a niche developing smaller multi-tenant flex and last-mile facilities — often 30,000–100,000 sq ft — in tight urban locations where traditional spec buildings cannot be built.

Foundry Commercial and Colliers Development

These Southeast-focused platforms have been active in BTS transactions in the Jacksonville and Tampa markets, often working directly with corporate occupiers on site selection and facility design.

Market Conditions That Favor Each Approach

When Spec Wins

• Vacancy below 5%: When space is tight, tenants cannot wait 18+ months for a BTS to deliver. Spec buildings capture demand that would otherwise go unfilled or relocate out of market.
• Rent growth environment: Rising rents during construction increase spec building value at completion, expanding the development spread.
• Land-constrained markets: In markets like Miami-Dade where land for new development is scarce, spec building on one of the few available sites guarantees relevance in the market.

When BTS Wins

• Rising vacancy: When the market has available space, a tenant with specific requirements has no incentive to lease an existing spec building that doesn't meet their needs — BTS becomes the only viable solution.
• Large-format requirements: Tenants needing 500,000 sq ft or more are unlikely to find existing spec buildings that match their configuration. BTS is the default.
• Specialty requirements: Cold storage, high-power industrial, data center-adjacent facilities, and Class I rail-served properties virtually always require BTS because spec developers avoid the capital intensity and specialized risk.

The 2026 Developer Calculus

As of Q1 2026, Florida developers are navigating an environment that slightly favors disciplined spec over BTS for most market segments:

• Vacancy remains below 6% statewide — supportive of spec absorption
• Construction financing has tightened (lenders require 30–40% pre-leasing in some markets), limiting the most aggressive spec bets
• BTS tenants are actively seeking sites in Jacksonville and Central Florida, where large contiguous parcels remain available at reasonable prices

The markets where pure spec is most rational: Miami-Dade core, Tampa Bay I-4 west, Dade/Broward last-mile.

The markets where BTS is gaining share: Cecil Commerce Center (Jacksonville), Polk County (Lakeland), Osceola County (highway-accessible large format sites).

For developers entering Florida in 2026, the optimal strategy is often a hybrid: develop spec in the 150,000–300,000 sq ft range in primary markets while pursuing BTS commitments from large-format users in secondary markets where the tenant commitment justifies the infrastructure investment.
