Buying Commercial Land in Florida: Future Land Use, Impact Fees, Wetlands and Permits

Commercial

Oct 22

Quick answer: Before you buy a commercial parcel, get two things in writing: the future land use category on the comprehensive plan map and the zoning district, because Florida law requires every development order to be consistent with the adopted plan (s. 163.3194). Then budget what stands between closing and a building permit: impact fees under the Florida Impact Fee Act, a mobility fee in Port St. Lucie, an environmental resource permit from the water management district for any work in wetlands or for a site with more than 4,000 square feet of impervious or semi-impervious surface subject to vehicle traffic or 9,000 square feet in total, which covers most commercial sites, a federal section 404 permit from the Army Corps of Engineers if wetlands are filled, an FDOT connection permit for a driveway on a state road, and wildlife permits if gopher tortoises or scrub-jays are present. As a hypothetical, a 50,000 square foot warehouse in Martin County would owe $54,700 in county impact fees on the schedule effective January 1, 2026, before water and sewer connection charges. Several local schedules could not be confirmed, and I say which ones below.

A buyer looking at a vacant parcel on U.S. 1 or near an I-95 interchange usually asks me two questions: can I build what I have in mind, and what will it cost to get to a building permit? The first answer lives in the comprehensive plan and the zoning code; the second in fee schedules and permits from the local government, the water management district, the Army Corps of Engineers, FDOT and the wildlife agencies.

Future land use versus zoning

Every Florida city and county adopts a comprehensive plan with a future land use map. Zoning is the regulation that says what you can build on a specific parcel today. The two have to agree. Once a plan is adopted, all development orders "shall be consistent" with it, land development regulations such as zoning must be consistent too, and where a regulation conflicts the plan governs until it is amended (s. 163.3194(1)); consistent means the uses and intensities are "compatible with and further" the plan's (s. 163.3194(3)(a)). So commercial zoning under a residential plan category is a problem, not an opportunity.

If the map has to change, the small scale route under s. 163.3187 covers a use of 50 acres or fewer, changes only the map, needs one hearing before the governing board, and cannot take effect until 31 days after adoption; an affected person may petition within 30 days. Before you write a contract, get both designations in writing and ask a land use attorney whether your intended use is permitted outright, by special exception, or not at all.

The Florida Impact Fee Act and the local schedules

Impact fees are one-time charges for the capital cost of facilities a new building will use. Under the Florida Impact Fee Act (s. 163.31801), fees must rest on localized data no more than 4 years old and bear a rational nexus to the need the development creates. A local government must give at least 90 days notice before a new or increased fee, may not collect it before building permit issuance, and must credit required contributions dollar-for-dollar. Increases are capped: up to 25 percent phased over two annual increments, 25 to 50 percent over four installments, nothing above 50 percent, and no more than once every 4 years, absent an extraordinary circumstances finding with a study, two workshops and a unanimous vote. Water and sewer connection fees are outside the act.

Port St. Lucie's city schedule, revised May 20, 2026 and effective June 30, 2026 through June 29, 2027, charges public buildings and law enforcement fees per 1,000 square feet: office $288 and $358, warehousing $80 and $58; St. Lucie County's separate road, fire and EMS and other fees apply on top, and I could not confirm them. Martin County's schedule effective January 1, 2026 gives totals per 1,000 square feet that include transportation, public buildings, law enforcement, fire rescue and a 1.5 percent administrative fee: office $3,515, general industrial $2,698 and warehousing $1,094. For Brevard County, the posted commercial schedule is dated 2007 and lists office under 10,000 square feet at $8,763.40 per 1,000 square feet. A law firm summary dated July 27, 2026 reports that the county commission on July 21, 2026 approved an impact fee update study and directed staff to draft ordinances raising non-school fees; the firm's example takes that office fee to $13,145.10, no earlier than January 1, 2027. That is secondary; I could not confirm adoption. St. Lucie County's rate sheet did not extract cleanly and Indian River County's could not be fetched; I quote neither.

A hypothetical: a 50,000 square foot warehouse in Martin County on the January 1, 2026 schedule, or 50 units of 1,000 square feet.

Line (Martin County, Warehousing, LUC 150)	Rate per 1,000 sq ft	Amount for 50,000 sq ft
Transportation	$932	$46,600
Public buildings	$42	$2,100
Correctional and law enforcement	$88	$4,400
Fire rescue	$16	$800
Administrative fee (1.5 percent)	$16	$800
Total	$1,094	$54,700

That is 50 times the county's $1,094 total, before connection charges and credits. The same building inside Port St. Lucie would owe the city $4,000 in public buildings fees and $2,900 in law enforcement fees, plus the mobility fee below and those county fees.

Mobility fees in Port St. Lucie

A local government that repeals transportation concurrency may adopt a mobility plan and fee instead (s. 163.3180(5)(i)), and Port St. Lucie does, in place of a city road impact fee. The posted schedule is from 2022, charged per square foot in three assessment areas (east, southwest and northwest of I-95): commercial storage, which includes warehouse, $0.56, $0.44 and $0.59; industrial $0.70, $0.55 and $0.74. On the 50,000 square foot warehouse east of I-95, that is $28,000. A September 23, 2026 WQCS report says an ordinance adopting the city's 2050 Mobility Plan, with $2.2 billion of projected improvements, would take effect December 31, 2026, with no new fee amounts reported. I found no adopted replacement for the 2022 schedule, so confirm the rate on your permit date.

Water management district permits and the section 404 program

Most commercial sites need an environmental resource permit (ERP) from the water management district. Under Rule 62-330.020(2), Florida Administrative Code, a permit is required for a project that is in, on or over wetlands or other surface waters, creates more than 4,000 square feet of impervious or semi-impervious surface subject to vehicle traffic or more than 9,000 square feet in total, exceeds 5 acres, or is part of a larger common plan of development, among other triggers. St. Lucie and Martin counties are in the South Florida Water Management District; Brevard and Indian River are in the St. Johns River district. Chapter 62-330 was amended effective June 28, 2024 with new stormwater criteria; applications deemed complete by December 28, 2025 qualified for grandfathering under the older criteria; for a parcel with an existing permit or conceptual approval, your engineer can tell you which criteria apply.

Filling wetlands also requires a federal permit under section 404 of the Clean Water Act. Florida had taken over the program, but a federal court vacated that approval in February 2024, and on July 12, 2024 the Army Corps of Engineers' Jacksonville District said it was processing applications in the formerly state-assumed waters. On March 27, 2026 the D.C. Circuit affirmed the vacatur on Endangered Species Act grounds, and the program remains with the Corps; a bill to codify Florida's program had passed the U.S. House and was pending in the Senate (law firm summary, April 6, 2026). So a wetland fill permit today comes from the Corps, and the state ERP is a separate permit.

Driveway access, gopher tortoises and scrub-jays

A driveway onto a state road needs an FDOT connection permit, because access to the State Highway System is regulated by the department (s. 335.182). A "significant change" that reopens the permit includes a change in use or an expansion that increases trip generation by more than 25 percent, peak hour or daily, and by more than 100 vehicles per day over the existing use (s. 335.182(3)(c)), which matters when you change the use of an improved parcel.

Gopher tortoise burrows cannot be graded over. The Florida Fish and Wildlife Conservation Commission revised its permitting guidelines in 2023, no longer issues incidental take permits, and applies its current mitigation table to complete applications submitted on or after August 1, 2026. A smaller permit covers sites with few burrows and a conservation permit covers larger impacts. The Florida scrub-jay is a federally listed species; a January 17, 2020 federal notice concerned an incidental take permit and habitat conservation plan for about 1.02 acres of occupied habitat in Brevard County, so even a small scrub parcel can trigger a federal process. A protected species survey by an environmental professional belongs in your due diligence period.

Utilities, concurrency and the site plan

Concurrency means the facilities a project needs must exist when it does. Sewer, solid waste, drainage and potable water must be available no later than the certificate of occupancy, and before approving a building permit the local government must consult the water supplier (s. 163.3180(1) and (2)). Transportation and school concurrency apply only where the local government has chosen them. Ask the utility early whether capacity is committed to the parcel; on the utility pages I read, neither Port St. Lucie nor Brevard County publishes an availability letter fee or turnaround.

In Brevard County a site plan is required to build or expand a building, starting with a pre-application conference ($2,338). A full site plan review is $4,463 plus $450 per acre and $20 for sewer or $75 for septic. The submittal requires an approved concurrency application, drainage calculations, a tree survey and a traffic analysis if required.

What I could not confirm

I could not confirm St. Lucie County's current fees, Indian River County's schedule, whether Brevard County's proposed increases were adopted, Port St. Lucie's mobility rate for 2027 or its site plan fees (posted as an image), the fate of the federal bill on the section 404 program, or the gopher tortoise mitigation dollar amounts. For each, get the dated document from the agency.

Price the land last. Get the future land use category and zoning in writing, have a land use attorney read them against your intended use, have a civil engineer scope the ERP, have an environmental professional walk the site for wetlands, tortoises and scrub, and ask every agency for a dated fee schedule. The parcel that looks cheaper per acre is sometimes the one with the wetland in the middle and no sewer at the road.

Questions buyers ask about commercial land

Does the zoning or the future land use map control?

Both must agree. Section 163.3194(1)(a) requires development orders to be consistent with the adopted comprehensive plan, and (3)(a) defines consistency as being compatible with and furthering the plan's uses and intensities. Where a zoning regulation conflicts with the plan, the plan governs until the regulation is amended.

How long does a small scale plan amendment take to become effective?

Under s. 163.3187, a small scale amendment covers 50 acres or fewer, needs one adoption hearing before the governing board, and may not become effective until 31 days after adoption. An affected person can petition within 30 days.

How much can an impact fee rise at once?

Under s. 163.31801(6), not more than 50 percent of the current rate, phased in two or four installments depending on the size of the increase, and no more than once every 4 years, unless the local government meets the extraordinary circumstances test with a study, two workshops and a unanimous vote.

Who issues wetland (section 404) permits in Florida now?

The Army Corps of Engineers' Jacksonville District. A federal court vacated the approval of Florida's state program in February 2024, the D.C. Circuit affirmed on March 27, 2026, and the program remains with the Corps. A federal bill to codify Florida's program was pending in the Senate as of an April 6, 2026 law firm summary.

When do I need a water management district permit?

Under Rule 62-330.020(2), for any work in wetlands or surface waters, more than 4,000 square feet of impervious or semi-impervious area subject to vehicle traffic, more than 9,000 square feet of total impervious or semi-impervious area, or a project over 5 acres, among other triggers. St. Lucie and Martin are in the South Florida district; Brevard and Indian River are in the St. Johns River district.

What is a mobility fee?

A fee a local government may adopt in place of transportation concurrency under s. 163.3180(5)(i). Port St. Lucie charges one per square foot by assessment area; its posted 2022 schedule lists $0.56 per square foot for commercial storage east of I-95, and a new mobility plan ordinance was reported to take effect December 31, 2026 with no new amounts published.
