Land questions in Martin County start in the same place: the official parcel map. Here's how to use the Martin County GIS map to find owners, acreage and boundary lines, and where it falls short.
We'll cover the official map, the communities and terrain around Ocean Breeze, how property lines work in Florida, and where the deeds come from.
Martin County at a glance: towns and land
Parcel searches in Martin County tend to center on Stuart, the county seat, plus Jupiter Island, Ocean Breeze, Sewall's Point, and Indiantown. The county dates to 1925, named for John W. Martin, and older deeds may still refer to landmarks from that era. Roughly 163,315 people (Census Bureau, 2023) share Martin County's 544 square miles of land. Subdivision plats fill most of the map near Stuart; open acreage survives mainly at the edges of the county. Public ground such as Hobe Sound National Wildlife Refuge appears as large unbroken blocks, and the private parcels around it draw hunters and recreation buyers.
Where to open the official Martin County GIS map
Open the Martin County parcel viewer, the map the county itself publishes for Stuart and the rest of Martin County. Rural tracts in Martin County often have no street address, so try an owner search or simply pan to the area and click. Our Martin County listing carries the same link plus neighboring maps.
What the Martin County GIS map shows about lot lines
Lines on the map show roughly where one parcel near Sewall's Point ends and the next begins; the exact spot is a surveyor's call. Florida uses the Public Land Survey System, so rural deeds in Martin County often describe land by section, township and range, and you can match the call to the grid on the map. If a neighbor's fence near Sewall's Point and the map disagree, neither one is proof. A survey is.
Where Martin County deeds and plats are kept
Two offices matter for land records in Martin County: the county property appraiser for parcel data and values, and the clerk of the circuit court (official records) for deeds and plats. Florida splits the job, and Martin County is no exception: the property appraiser values parcels and keeps the assessment maps, while the clerk of court records deeds, mortgages and plats. Easements and rights-of-way are usually in recorded documents, not on the parcel map, so read the deed itself for a tract near Palm City.
Who uses the Martin County parcel map
Contractors quoting work near Palm City check frontage and lot depth on the map before they drive out. Buyers new to Ocean Breeze often pull the neighbors' parcels too, to see how big the surrounding lots are and who owns them. Current owners in Martin County pull their parcel before a tax appeal, a refinance or a talk with the neighbor about a fence.
Private and public hunting ground in Martin County
Near Jupiter Island, a single field edge can separate two owners with very different answers about access; the map tells you which is which. Public options include Hobe Sound National Wildlife Refuge; check the boundaries carefully, because private inholdings and neighboring tracts aren't open to the public. The Florida Fish and Wildlife Conservation Commission handles licenses, seasons and public-land maps for Martin County. A landowner near Palm City is more likely to say yes to a hunter who names the exact parcel and offers a phone number.
Work and land use in Martin County
By the Census Bureau's 2022 count, 6,296 business establishments operated in Martin County. Professional and technical services had the most, followed by retail trade and construction. What stands out is scenic and sightseeing transportation, water transportation, and transportation equipment manufacturing: those sectors make up a much larger slice of local businesses than they do nationally. Recreation money shows up in the Martin County land market as demand for cabin sites and small getaway parcels. Keep that in mind when you compare parcels in Martin County: who works here shapes what land sells.
Finding vacant land and acreage in Martin County
To use the Martin County GIS map for a vacant land search:
- Follow the roads out of Indiantown with aerials on and mark every tract without a rooftop.
- A tax bill mailed far from Palm City usually means an absentee owner, so note the mailing address on each record.
- Assessed values lag the market, but comparing tracts near Palm City still shows which ones the county rates higher.
- Make sure the parcel near Sewall's Point actually touches a public road, and ask how it's reached if it doesn't.
- Ask the local offices serving Sewall's Point about building permits and septic rules before you buy.
Before you rely on the data
Splits and sales near Palm City can take weeks or months to show up on the parcel layer. Acreage on the Martin County map is a tax figure; a survey is what a lender or buyer should rely on.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
