The Berkeley County, SC tax map is available free online through two county tools: the Advanced Mapping App at gis.berkeleycountysc.gov and the Property Card Search at berkeleycountysc.gov. Between them, you can pull up any parcel in the county by its Tax Map Sequence (TMS) number, street, or owner name and see boundaries, acreage, ownership, zoning, flood zone status, tax district, and assessed value.1Berkeley County GIS.

Searching by TMS, Address, or Owner
Every parcel in Berkeley County has a unique TMS number, and that number is the fastest way in. Enter it in either search tool and you land directly on the property.
If you don’t know the TMS, search by street name or owner. Two quirks matter. When searching by street, drop the street type: enter “Oakley,” not “Oakley Road.” Owner-name searches work best in last-name-first format.2Berkeley County Government. Property Card Search The Property Card Search returns the detailed record; the Advanced Mapping App plots the parcel on the interactive map.
Using the Interactive Map
Once a parcel loads in the Advanced Mapping App, you can zoom in to inspect exact boundary lines, pan across neighbors, and click any adjacent parcel to see its data. Zooming is particularly useful for checking where your lines meet roads or rights-of-way.
Berkeley County maintains more than 500 digital layers, including zoning, political boundaries, and street centerlines.3Berkeley County Government. Geographic Information Systems You can toggle aerial photography on top of parcel outlines to see structures and vegetation, or switch to other overlays as needed. When you have the view you want, export it as a PDF, JPEG, or PNG for your records or to send to a surveyor, contractor, or attorney.1Berkeley County GIS. Berkeley County GIS – Advanced Mapping App
What the Parcel Record Shows
Clicking a parcel opens more than a shape on the screen. The associated record includes acreage, the tax district the parcel falls within, and zoning classifications that control what can be built or operated on the land.
The tax district assignment is not cosmetic. South Carolina law requires that real estate be taxed in the county, city, ward, or town where it sits, so the district shown on the map determines which millage rates apply to the bill.4South Carolina Legislature. South Carolina Code of Laws Title 12 Chapter 37 – Assessment of Property Taxes – Section: 12-37-890 County assessors are required by state law to keep a continuous record of deed sales, building permits, and tax maps as part of the ongoing reassessment program, so what you see should reflect the current ownership and improvement information on file.5South Carolina Legislature.

Flood Zone Layers
FEMA flood zone boundaries are one of the GIS layers, and this is where the map has real financial consequences. If a property sits within a Special Flood Hazard Area, flood insurance is mandatory for the life of any mortgage on the property, and an elevation certificate with photos is needed for proper insurance rating.6Berkeley County Government. Floodplain Management
If you think the boundary is wrong for your parcel, you can apply to FEMA for a Letter of Map Amendment (LOMA). A successful LOMA can remove a structure from the designated flood zone, which typically ends the insurance mandate.6Berkeley County Government. Floodplain Management
Assessed Value and Classification
The parcel record also carries the fair market value and classification that drive your tax bill. South Carolina applies different assessment ratios by use: an owner-occupied primary residence is assessed at 4% of fair market value, commercial or rental property at 6%, individually owned agricultural land at 4%, and corporate-owned agricultural land at 6%.7South Carolina Revenue and Fiscal Affairs Office. Property Tax FAQ The assessed value is then multiplied by the millage rate for the tax district on the map. Berkeley County’s base millage for 2025/2026 is 0.2465, with additional taxes or reductions where the property sits inside an incorporated area.8Berkeley County Government. Computation 2025-2026
South Carolina requires each county to reappraise and equalize property values every five years, with new valuations completed by the end of December in the fourth year, notices sent to every taxpayer for any change in value or classification of $1,000 or more, and new values implemented in the fifth year.9South Carolina Legislature. South Carolina Code of Laws Title 12 Chapter 43 – Section: 12-43-217 When that cycle turns, the value tied to your parcel on the map updates.
If the map data or valuation looks wrong after a change of $1,000 or more, you have 90 days from the mailing date of the assessment notice to file a written objection with the county assessor. Miss that window and the right to challenge that year’s valuation is gone.10South Carolina Legislature.

When New Parcels Appear on the Map
Recently subdivided or combined parcels don’t show up on the GIS map right away. When a landowner divides a tract, the Planning and Zoning Office must first approve the subdivision, then the plats are recorded with the Register of Deeds. Real Property Services then receives the plats and assigns new TMS numbers to each lot, and E911 Address Information enters them into the GIS system and assigns new street addresses.12Berkeley County Government. Frequently Asked Questions – Address Information
The whole chain from recording to new TMS and address usually takes two to four weeks. If a subdivision was recorded last week and isn’t on the map yet, that’s normal.12Berkeley County Government. Frequently Asked Questions – Address Information
Getting Physical or Certified Copies
Some filings and transactions call for a physical or certified tax map rather than a digital export. Requests go through Berkeley County’s Real Property Services department, which also runs an online portal for submitting applications and tracking status.13Berkeley County Government. Real Property
Under South Carolina’s Freedom of Information Act, public bodies may charge for searching, retrieving, and copying records, but the fees cannot exceed the actual cost of the work. The hourly rate is capped at the prorated salary of the lowest-paid qualified employee, copy charges cannot exceed prevailing commercial rates, and no fee applies to records transmitted electronically. After you submit a written request, the county has 10 business days to respond with a determination; for records older than 24 months, that window is 20 business days.14South Carolina Legislature.
