Every quarter, a fresh batch of Palm Beach County industrial reports lands on desks in Delray, Boca, and Palm Beach Gardens, and every quarter, the headline lands the same way. Vacancy is in the high sevens or low eights. Rents have softened. Absorption has been negative for two quarters. Read the tape and the market looks tired.
Then a Lake Worth broker calls with a 6,000-square-foot listing on Military Trail, and it's gone in nine days at asking. Both facts are true. Only one of them is the market you can actually buy in.
The headline is a weighted average of two unrelated tapes
The Palm Beach County industrial base is roughly 56.6 million square feet, and the countywide vacancy rate is being pulled in opposite directions by two supply cohorts that don't compete for the same tenant, the same rent, or the same buyer.
CBRE's Q1 2026 read put countywide vacancy at 7.7% and average asking rent at $13.87, the first uptick after a 14% slide from the Q4 2023 peak of $15.20 down to $13.04 in Q3 2025. Berger Commercial's Q2 2026 report moved vacancy to 8.0% and rents to $15.32. Colliers had Q1 at 7.2%. The disagreement across brokers is itself a signal. When three professional research desks can't converge inside 80 basis points, the underlying market is not one market.
| Submarket | Vacancy (Q1 2026, CBRE) | Asking rent band |
|---|---|---|
| Lake Worth | 1.0% | $16–$21 |
| Jupiter | 1.8% | $16–$21 |
| Boca Raton | 3.2% | $16–$21 |
| Northern PBC "Out of Submarket" bulk | Elevated | $8.50–$11.00 |
| County headline | 7.7% | $13.87 |
The core infill submarkets are running at practical full occupancy. The headline vacancy is being produced almost entirely by a single band of large-format bulk product in the northern county.
What actually delivered, and where
Since 2022, roughly 4.8 million square feet of new industrial has come online in Palm Beach County. About 1.8 million of that is concentrated in what CBRE labels the northern county's Out of Submarket corridor, a stretch of large-format, high-clear bulk warehouse product built to a distribution profile that the county's tenant base does not, on the whole, ask for. Over 1.2 million square feet of that cohort is still available.
Palm Beach County's demand base is service industrial, construction and building trades, landscaping and marine services, luxury logistics for the coastal residential base, and last-mile distribution serving affluent consumption. Those tenants take 3,000 to 40,000 square feet, want 22-to-28-foot clear, and want to be inside the population they serve. They do not backfill 250,000-square-foot cross-dock buildings priced in the high single digits an hour off their delivery routes.
The market has been busy on the infill side even while the headline softened. FRP Holdings completed a 200,000-square-foot infill logistics warehouse in Delray Beach in April 2026. Woodmont and Butters leased up 7th Avenue Logistics, a 75,989-square-foot Class A facility in Lake Worth. Cushman & Wakefield, in partnership with CBRE, is currently marketing a 95,720-square-foot small-bay portfolio straddling Military Trail that is 99% occupied with a unit mix running 400 to 4,800 square feet. None of that reads like an 8% vacancy market.
Why the two cohorts do not price against each other
The gap between $8.50 asking on northern bulk and $21.00 asking on infill Lake Worth is not a spread you arbitrage. It is two different products serving two different tenants:
- Infill tenants need proximity to end customers in Palm Beach, West Palm Beach, Delray, Boca, and Jupiter. Their P&L is dominated by driver hours and job-site turns, not shell rent. A dollar per foot of rent premium is trivial against fifteen extra miles each way on a fleet.
- Bulk regional tenants underwrite the whole Southeast Florida corridor as one market. If Palm Beach bulk prices at $9 and Broward or western Miami-Dade bulk prices at $10, they take Palm Beach. If it prices at $12, they don't. That single-digit sensitivity is why the northern overhang persists as available product rather than clearing at a modest concession.
A buyer looking at the county average sees a market absorbing a supply shock. A buyer looking at Lake Worth or the Riviera Beach infill belt sees a market where inventory is effectively exhausted and the next comparable listing may not exist.
The underwriting error this creates
The most common mistake we see on infill deals right now is a mark-to-market rent assumption built on the countywide $13.87 to $15.32 range. On a small-bay building in West Palm Beach proper, Lake Worth, or the Riviera Beach service belt, that assumption understates renewal rents by $3 to $6 a foot depending on ceiling height, power, and dock configuration. On a 30,000-square-foot building, that is $90,000 to $180,000 of NOI the seller is giving away if they price off the headline.
The inverse mistake is worse. A bulk building in the northern Out of Submarket band, underwritten to countywide averages, over-credits achievable rent by a similar magnitude and misreads a 12-to-18-month lease-up as a 6-month lease-up. That is where cap rate arithmetic breaks. South Florida industrial cap rates have expanded to an average near 6.3% to offset borrowing costs. On bulk product with real lease-up risk, the exit cap needs another 50 to 100 basis points beyond that, and the interim carry has to be underwritten honestly.
Two properties in the same county, two different cap rate frameworks, one countywide average that describes neither.
What to stress-test before pricing an infill exit
For owners considering a disposition in the next 12 months, the questions that actually move value are narrower than the market report suggests:
- What is the true rent roll spread against current small-bay asking, unit by unit? On buildings with staggered 3- and 5-year rollovers, the mark-to-market gain is often the entire investment thesis for a buyer.
- Is the property inside the Lake Worth, Jupiter, Boca Raton, West Palm Beach proper, or Riviera Beach infill footprint, or is it drifting toward the bulk overhang zone? The border matters more than the county line.
- What does insurance look like on a 2026 renewal, and does the pro forma expense stop absorb it? Florida commercial insurance moves NOI more than rent growth does at this point in the cycle.
- Are 1031 buyers in the exchange window? Palm Beach infill industrial has become one of the preferred landing spots for coastal multifamily and NNN sellers looking for durable cash flow, and that buyer pool prices differently than institutional core capital.
For buyers, the corresponding discipline is refusing to accept a broker's countywide comp set. Infill deals need infill comps, and the comps are thinner than the market reports imply because the product does not turn.
FAQ
Which submarkets qualify as "infill" for underwriting purposes?
The tight submarkets flagged in Q1 2026 broker data are Lake Worth at 1.0%, Jupiter at 1.8%, and Boca Raton at 3.2% vacancy. Practitioner-level infill also includes West Palm Beach proper and the Riviera Beach service belt, where inventory is described as effectively exhausted and where small-bay product continues to trade actively.
If countywide rents fell 14% from the Q4 2023 peak, why don't infill rents show the same decline?
Because the decline was supply-driven and concentrated in the northern bulk cohort. The 1.8 million square feet of northern Out of Submarket product priced at $8.50 to $11.00 pulled the weighted average down. Infill submarkets held rents in the $16 to $21 range through the same period.
How should a 1031 exchange buyer think about Palm Beach industrial right now?
The buy universe is narrower than the market report suggests. If the objective is durable cash flow with real mark-to-market upside on renewal, the target is small-bay and mid-bay infill product in the tight submarkets, underwritten with property-specific comps and a 2026 insurance number. Bulk product priced off the headline may look like a yield opportunity and usually is not.
Position your asset against the right market, not the average
The Palm Beach County industrial market is neither the softening story the headline tells nor the runaway story the small-bay tape tells. It is two markets, and pricing an infill asset against countywide averages leaves basis on the table on the way out and creates lease-up risk on the way in. If you own industrial in Palm Beach County and are weighing a 2026 or 2027 exit, or are evaluating a 1031 landing in the infill belt, Florida Commercial Group can walk your rent roll, expense stack, and comp set against the submarket that actually prices your building.
