Martin County GIS: Property Appraiser Interactive Parcel Map & Search
The official Martin County Property Appraiser map is the county’s MC Maps parcel viewer at geoweb.martin.fl.us/general. It is useful when a standard property record does not give enough geographic context.
You can locate parcels by address, owner or parcel number, move from the map to the Property Appraiser record, identify surrounding parcels, build a distance buffer and create mailing labels for selected properties.
For a single property’s values, exemptions or ownership record, use the Property Appraiser’s Real Property Search alongside the map. The two tools complement each other but answer different questions.
MC Maps, Real Property Search or Property Information Lookup?
Martin County offers several property tools. Choosing the correct one first is faster than trying to force every question through the GIS map.
| Your Question | Best Official Tool | What It Is Best At |
|---|---|---|
| Where is the parcel and what surrounds it? | MC Maps | Parcel location, nearby properties, map navigation and spatial research |
| Who owns it and what are its assessment details? | Real Property Search | Owner, Parcel ID, account, subdivision, address, values and property record |
| What properties sold nearby? | Real Property Sales Search | Sale-date, price, property-type and location research |
| What is the flood zone, zoning, wind speed or utility information? | Martin County Property Information Lookup | Flood, land use/zoning, schools, utilities, wind speed and other county information |
| I need many parcels or GIS files | Property Appraiser Data Downloads | CSV files, Excel reports, parcel data, shapefiles and geodatabases |
| I need a deed or recorded legal document | Martin County Clerk Records Search | Deeds, mortgages, liens, plats and Official Records |
How to Search the Martin County Property Appraiser Map
The Property Appraiser’s official MC Maps instructions use a parcel-search panel with search choices for address, owner, parcel number and location-based research.
Open Official Martin County GIS MapStart with the strongest identifier
Use a parcel number when you already know it. Otherwise use the address or owner search. Location tools are better when you want to select an area rather than a known parcel.
For an address, enter the street number and street name
The official MC Maps instructions describe using the Address tab, entering the street number and street name, then running the search.
Confirm the highlighted parcel
When an address match is found, MC Maps zooms to the parcel and identifies the matching real estate record. Confirm the PCN, owner and address before doing further research.
If there is no match, change the search method
First check for a typing error. If the address still returns no result, use Owner, Parcel # or Location rather than repeatedly submitting the same address.
After opening MC Maps
- Open the parcel-search controls.
- Choose Address, Owner, Parcel # or the location-based option that matches your task.
- Search for the property.
- Confirm the PCN and site address in the result before selecting nearby parcels or using map tools.
- Open the linked Property Appraiser record when you need assessment details rather than only map context.
What Appears After You Find a Parcel in MC Maps?
The official map instructions describe a result panel containing general parcel information such as the Parcel Control Number (PCN), owner and address.
Property Appraiser Record
The map provides a route back to the Martin County Property Appraiser property card. Use that record for owner, legal description, acreage, property-use information, values and recent sale details.
County Property Information
The map also connects property research with Martin County’s broader information lookup, which can provide planning, flood, utility and other government context.
After opening Real Property Search
- Search by Parcel ID, Account Number, subdivision, address or Owner Last Name.
- Open the same parcel you confirmed on the map.
- Check site address and ownership before reviewing values.
- Review land, building, sale, assessment and exemption information as needed.
- Keep the Parcel ID or Account Number for later county or tax searches.
Use the MC Maps Buffer Tool to Find Properties Around a Selected Parcel
One of Martin County’s more useful GIS features is the parcel buffer. The Property Appraiser publishes instructions for selecting parcels within a specific distance and turning the result into a mailing-label list.
Find the subject property first
Search the address or parcel and confirm that MC Maps has highlighted the correct location.
Open the Location search tools
The official instructions direct users to the Location tab for area-based parcel selection.
Choose Buffer Graphic and a distance
Enter the buffer distance and choose the available unit of measurement, such as feet or meters.
Select the subject parcel
Use the point-selection tool on the parcel. MC Maps then identifies parcels overlapping the selected buffer and lists them in the results.
Export mailing labels when needed
The official workflow provides an envelope-style mailing-label export that creates owner names and mailing addresses in standard Avery 5160 format.
When a Spreadsheet Is Better Than a Map
MC Maps is strongest for location and surrounding-parcel work. If you need to sort many properties or analyze data in a spreadsheet, the Property Appraiser’s regular search tools are usually more efficient.
Real Property Search
Search by Parcel ID, Account Number, subdivision, address or Owner Last Name.
Open Property SearchReal Property Sales Search
Use the dedicated sales database when your goal is comparable transactions rather than simply locating parcels.
Open Sales SearchCustom Data Filters
For larger public-data tasks, use the Property Appraiser’s downloadable reports and custom filtering tools.
Open Data DownloadsExport search results to a spreadsheet
Martin County’s published search instructions provide an Export List to Table (.CSV) option. The resulting file can include useful parcel information such as sales, values, mailing addresses and acreage.
Download Martin County Parcel GIS Data for ArcGIS, QGIS or Database Work
The Property Appraiser publishes GIS downloads for users who need more than an interactive browser map. Current downloadable GIS packages include parcel-related shapefiles and geodatabases built from the Property Appraiser’s Real Master, Real Land and Real Improvement data.
| Dataset | What It Contains | 2026 Update Shown |
|---|---|---|
| Real Master GIS | Core parcel, owner, land-use, subdivision, address and assessment-related fields | GIS package dated August 25, 2026 |
| Real Land GIS | Residential, commercial and agricultural-classified land data | GIS package dated August 25, 2026 |
| Real Improvement GIS | Building and improvement information linked with real property | GIS package dated August 25, 2026 |
| Ownership / transfer CSV data | Owners, sales, legal descriptions, exemptions and related CAMA fields | Several downloadable files dated September 9, 2026 |
After opening Data Downloads
- Decide whether you need a ready-made report, tax-roll/CAMA export or GIS package.
- Check the displayed file-update date before downloading.
- For spatial analysis, use the GIS Data section.
- For tabular analysis, use the Real Master, Owners, Transfers, Land or other CSV downloads.
- For one property only, return to Real Property Search rather than downloading a countywide file.
Do Not Force Flood, Zoning and Utility Questions Through the Property Appraiser Map
For planning and due-diligence questions, Martin County’s broader government maps provide information that the appraisal map is not designed to decide.
Property Information Lookup
Search by owner, address, account number or PCN to review available flood, land use/zoning, wind speed, school, utility, solid-waste and elected-official information.
Open Property Information LookupFEMA Flood Zones
Use Martin County’s flood resources to determine the FEMA flood zone and check whether an elevation certificate is available.
Open Flood InformationGeneral County Map
The Martin County General Map is another official entry point for county property and geographic information.

Martin County Property Appraiser Map FAQs
1. What is the official Martin County Property Appraiser map?
The official interactive parcel map is MC Maps at geoweb.martin.fl.us/general/. It is linked by the Martin County Property Appraiser and Martin County government for parcel and property-location research.
2. Can I search the Martin County GIS map by owner, address or parcel number?
Yes. The Property Appraiser’s official MC Maps instructions describe searches by address, owner, parcel number and location. When an address match is found, the map identifies the matching parcel and displays its result information.
3. What is the difference between MC Maps and Martin County Real Property Search?
MC Maps is best for parcel location, surrounding properties and spatial tools. Real Property Search is better for detailed owner, address, Parcel ID, Account Number, subdivision, assessment, sale and property-record information.
4. What information appears when I find a parcel in MC Maps?
The official map instructions describe general result information including the Parcel Control Number, owner and address, along with links that can take users to broader county information and the Property Appraiser real-property card.
5. Can I use the Martin County Property Appraiser map as a legal property survey?
No. The Property Appraiser states that property and map data is compiled for assessment purposes and should not be relied on as a legal ownership or boundary determination. Use a licensed surveyor and recorded documents when exact boundaries matter.
6. How do I find owners around a Martin County parcel and create mailing labels?
MC Maps includes a buffer workflow. Find the subject parcel, use the Location tools, enable the buffer option, choose a distance, select the parcel and review the surrounding results. The official instructions also provide a mailing-label export in Avery 5160 format.
7. Can I download Martin County parcel GIS data instead of using the web map?
Yes. The Property Appraiser’s Data Downloads page provides GIS shapefiles and geodatabases for Real Master, Real Land and Real Improvement data, along with CSV and other tax-roll/CAMA exports.
8. Why might a Martin County map value still show 2025 data during 2026?
The Property Appraiser’s current map-search disclaimer states that values presented in that data are certified for the 2025 tax roll. Martin County has separately published 2026 preliminary certification data, so check the tax year and source before comparing values.
9. Where should I check Martin County zoning and flood-zone information?
Use Martin County’s Property Information Lookup for available zoning, land-use, wind-speed, utility and related property information. For FEMA flood-zone research, use the county’s official Flood Protection and flood-map resources rather than relying only on the Property Appraiser parcel map.
10. Who should I contact if the Martin County parcel map or property record looks wrong?
Contact the Martin County Property Appraiser at 772-288-5608 or info@pamartinfl.gov. Have the Parcel ID or Account Number, property address and the exact field or map issue ready so staff can identify the record quickly.
