Industrial and Flex Space on the Treasure Coast and Space Coast: Types, Zoning and Numbers

Commercial

Oct 22

Quick answer: Industrial property on these two coasts ranges from a mini-warehouse to a 1.8 million square foot distribution center, and the label on the listing tells you less than the clear height, the door count, the electrical service and the zoning district. In Port St. Lucie, the Light and Heavy Industrial categories pair with the WI, GU and IN zoning districts and Planned Industrial Park with PUD; in Brevard County the classifications are IU, IU-1, PIP, PBP and BU-2. The most recent brokerage statistics I could read are Matthews' second quarter 2025 reports, which put vacancy at 3.3 percent in St. Lucie, 3.0 percent in Martin, 15.8 percent in Indian River and 3.5 percent in Brevard, and those are one firm's measurements with no metric definitions. I did not find an industry definition of flex, clear height or truck court that I could cite, so this article tells you what to ask rather than what the standard is.

A business owner who needs a 10,000 square foot bay with a dock door, an investor comparing a warehouse in Fort Pierce with one in Melbourne, and a landowner asking whether a parcel can hold a distribution building are asking the same three things: what kind of property is this, what should I check, and what do the market numbers mean? Here is what I could confirm for both coasts, and where the sources ran out.

What the building types are

The U.S. Energy Information Administration's commercial building survey defines warehouse and storage buildings as those used to store goods, manufactured products, merchandise, raw materials or personal belongings, with subtypes for refrigerated and non-refrigerated warehouses, distribution or shipping centers and public rental storage. Local governments sort the same buildings by use, because the use drives the fees. Port St. Lucie's 2022 mobility fee schedule groups "Industrial" (assembly, fabrication, manufacturing, research and development, trades, utilities), "Commercial Storage" (mini-warehouse, boat, RV and outdoor storage, warehouse) and "Distribution Center" (cold storage, fulfillment centers, high-cube).

Matthews' second quarter 2025 reports split industrial into flex, logistics and specialized buildings without defining any of them, and I did not find an industry glossary I could cite for "flex," so treat the word as a starting point and read the floor plan.

The features that matter

Four things usually decide whether an industrial building works for a user: clear height (the usable vertical space inside), the loading doors, the electrical service and the truck court (the paved area where trucks maneuver to the doors). I could not retrieve an industry standards page for any of these terms. In North America the most common loading dock height is 48 to 52 inches, with some up to 55 inches, and a dock leveler is a height adjustable platform that bridges the dock and the truck (Wikipedia, secondary). A building with grade-level doors and no raised dock serves a different user than a dock-high building, so count both. I found no sourced figures for amperage or phase and no standard truck court depth, so the checklist is built around questions.

Clear height, how it was measured, and your inspector's or engineer's own measurement
Number and type of doors (dock-high, grade level or both) and the dock height
Electrical service at the meter, confirmed by the utility and a licensed electrician
Truck court depth and turning room, from the site plan
Future land use category and zoning district, in writing from the local government
Lot coverage, impervious surface and height limits for that category

Zoning in Port St. Lucie

Port St. Lucie's Future Land Use Element, adopted October 26, 2020, creates three industrial categories. Light Industrial (LI) is primarily for light manufacturing, assembling, warehousing and storage. Heavy Industrial (HI) adds the more intensive uses, including large scale manufacturing and citrus processing, for sites with access to major transportation corridors. Planned Industrial Park (PIP) is an economic activity center for the city's targeted industries. All three carry 50 percent lot coverage, 80 percent impervious surface and a 35 foot height limit, with 75 feet allowed only inside a planned unit development larger than five acres with a master plan.

The element pairs each category with the zoning districts that implement it: WI, GU and IN for both LI and HI, with heavy industrial uses treated as special exceptions; PUD for PIP; and CS, GU and WI for Service Commercial, the category for the most intensive commercial development including wholesale and warehouses. The element does not spell out those abbreviations, and I could not read Chapter 158 of the city code, so confirm the district's full name and permitted use table with the city. The proposed 2050 plan (June 2026 draft) keeps the three categories, treats light versus heavy as a difference in uses allowed, not intensity, allows retail as an accessory use and raises PIP impervious surface to 90 percent; its adoption hearing was listed for October 2026. Industrial land inside the city is limited: the 2020 Economic Development Element put it at about 1 percent of the city's area against an 8.0 percent national average for similar communities.

Zoning in Brevard County

Brevard County's zoning code has five classifications an industrial buyer will meet: IU light industrial (Sec. 62-1543), IU-1 heavy industrial (Sec. 62-1544), PIP planned industrial park (Sec. 62-1542), PBP planned business park (Sec. 62-1541) and BU-2 retail, warehousing and wholesale commercial (Sec. 62-1483). I could read only the section titles, not the permitted use tables. The county's Future Land Use Element (September 2024) has two industrial designations: IU and IU-1 zoning may be permitted only inside Heavy/Light Industrial, and Planned Industrial permits only PIP zoning. The floor area ratio should not exceed 2.48 for light industrial and 1.76 for heavy. Planned industrial parks must be within 660 feet of a major transportation corridor on at least three acres, while light and heavy industrial uses shall not be located within 660 feet of those corridors, with listed exceptions, on minimum sites of 20,000 and 40,000 square feet. The named corridors include I-95, U.S. 1, U.S. 192 and State Roads 528 and 520. An industrial rezoning costs $1,855 plus $45 per acre (maximum acreage fee $2,240), and a written zoning verification costs $37.50, the least expensive written confirmation of a parcel's zoning I found.

The parks and projects I could confirm

On the Treasure Coast, the city's 2020 Economic Development Element describes Tradition Center for Commerce as a 1,175 acre part of the 8,200 acre Tradition community with over 10 million square feet (the element does not say whether built or planned). In Southern Grove, the city's page lists Legacy Park by Sansone Group, described as a Class A industrial complex exceeding 5 million square feet at build-out, with FedEx's 245,000 square foot sortation center as first tenant; Warehomes Precision's 400,000 square feet of manufacturing, distribution and flex space; and a Costco distribution center of 1.8 million square feet under construction. The city says fewer than 20 acres remained available by 2025. Its list of approved, upcoming site plans adds Project King, a 300,040 square foot warehouse and office building, and Project Suburban, a 378,523 square foot warehouse in Southern Grove. In Fort Pierce, the county owned Treasure Coast International Airport spans 3,844 acres with more than 1,000 acres available for lease and development, holds Foreign Trade Zone #218, and by the council's page is 8 miles from I-95 and the Turnpike.

On the Space Coast, the economic development council's 2026 releases include Acadian Contractors, moving from 11,000 to 45,000 square feet off Cox Road in Cocoa (May 14, 2026), and CesiumAstro, a new engineering and manufacturing facility in Melbourne with $25 million in capital improvements (October 15, 2026). Matthews' Space Coast report names Hines' purchase of Titusville Logistics Center for $42.2 million in January (no year given). Port Canaveral's logistics page lists Foreign Trade Zone #136, I-95 at 13 nonstop miles from the port entrance and a Florida East Coast Railway intermodal terminal 15 minutes away; it lists no available land or warehouse space.

What the brokerage statistics do and do not tell you

The most recent reports I could read are Matthews' second quarter 2025 industrial reports for the Treasure Coast (published August 7, 2025) and the Space Coast (published August 6, 2025, CoStar data). This is one firm's measurement.

County (Q2 2025)	Vacancy	Asking rent per SF	SF absorbed	Under construction	Avg sale price per SF	Cap rate
St. Lucie	3.3%	$16.92	negative 16,289	none	$116	8.0%
Martin	3.0%	$17.85	negative 1,066	36,000	$134	8.7%
Indian River	15.8%	$11.75	127,718	150,000 "on the way"	$111	8.1%
Brevard	3.5%	$13.62	131,000	148,000	around $120	"9.0% range"

They tell you the rough level of vacancy and asking rent by county in mid 2025, and that flex carried the highest rent in St. Lucie County at $17.90 per square foot. They do not define their metrics, do not say whether the rents are NNN or annual figures, and contain inconsistencies (the Space Coast report lists 3,900 square feet delivered in the quarter and 410,000 completed in the past year without defining the periods, and the Treasure Coast report gives Indian River sales volume as both $7.5 million and $66.3 million). They are more than a year old, and I could not open the 2026 editions. Use them to frame questions; to price a building you need its rent roll, its leases and your appraiser's comparables.

What I could not confirm

I could not retrieve industry definitions of flex, clear height, truck court, dock-high or power ratings, so the only sourced definitions here are the EIA's and Wikipedia's. Port St. Lucie's district names behind WI, IN, GU and CS are unconfirmed, as are the industrial districts of unincorporated St. Lucie County, Martin County, Indian River County, Melbourne and Palm Bay, and the text of Brevard's five sections. At the Fort Pierce airport, the 6,492 foot figure on the economic development council's page describes the instrument landing system and may not be the runway length. The Southern Grove page cites two acreages for the jobs corridor and two for the Costco site, so I quoted neither, and the Legacy Park figure is from the city page only.

A listing's label and a market report's averages are where the questions start. Get the clear height measured, count the doors, confirm the power with the utility, get the zoning and future land use in writing, and treat a statistic more than a quarter old as history. If the purchase is part of an exchange, start with the 1031 exchange guide.

Questions buyers and tenants ask about industrial space

What zoning allows a warehouse in Port St. Lucie?

The city's Future Land Use Element pairs the Light Industrial and Heavy Industrial categories with the WI, GU and IN zoning districts, and Service Commercial with CS, GU and WI. Planned Industrial Park is implemented through PUD zoning. The element does not spell out the district names, so confirm the permitted use table with the city.

What are Brevard County's industrial zoning classifications?

IU light industrial (Sec. 62-1543), IU-1 heavy industrial (Sec. 62-1544), PIP planned industrial park (Sec. 62-1542), PBP planned business park (Sec. 62-1541) and BU-2 retail, warehousing and wholesale commercial (Sec. 62-1483). A written zoning verification from the county costs $37.50.

How much land is available at Treasure Coast International Airport?

The county's economic development council says the airport spans 3,844 acres with more than 1,000 acres available for lease and development, and holds Foreign Trade Zone #218. I did not confirm rail access or a business park name.

How big is Legacy Park supposed to be?

The City of Port St. Lucie says the Sansone Group park exceeds 5 million square feet at build-out with over 3,000 jobs, and that FedEx's 245,000 square foot sortation center was the first tenant. That figure is from the city page only.

What was industrial vacancy in mid 2025?

Matthews' second quarter 2025 reports put vacancy at 3.3 percent in St. Lucie County, 3.0 percent in Martin, 15.8 percent in Indian River and 3.5 percent in Brevard. Those are one firm's figures, and the reports do not define their metrics.

What does flex mean in a listing?

I did not find an industry definition I could cite. Brokerage reports use flex as a subtype without defining it, so ask for the office share, the clear height and the door count rather than relying on the label.
