Union County, North Carolina GIS, parcel, zoning and land-record resources
A county parcel map is a starting point for locating land and finding its public records. Use North Carolina and Union County resources to locate assessment and recorded documents, identify governing offices, and organize findings in a Property Review.
Keep your research beside your property review
Start with an address, parcel number or listing. Keep the findings and questions for that property together in LandGauge.
On desktop, select an official source below to research side by side. Your review stays open while you switch sources. If a website will not display, use Open in new tab.
Confirm the governing jurisdiction first
Union County is a research starting point. Confirm county and municipal authority for assessment, zoning, subdivision, roads, utilities, wells, onsite wastewater and floodplain review. Tax parcels and GIS shapes do not prove legal boundaries, recorded access or development approval.

GISNC OneMap statewide parcels
Screen the county-sourced parcel layer and available attributes, then obtain the current tax card and map from the county.
NC OneMap aggregates data from county producers and the Eastern Band of Cherokee Indians. Check source dates and missing attributes; parcel shapes are not surveys or legal boundaries.

Use the state county website directory to reach the county tax assessor or land records office and request current parcel and tax information.
This is a government directory, not a direct tax lookup. NCDOR refers individual property tax questions to local county offices.

Find the relevant county or city planning and zoning office through the official county website, then ask about the exact site.
A county website does not establish zoning or legal-lot status. Confirm subdivision, minimum lot dimensions, access, building and utility rules with the governing office.

Use the county website to locate its register of deeds, then request actual deeds, plats, easements and restrictions.
This directory is not a document search. Confirm instruments, recording dates, access and fees with the county register of deeds.

Review state septic guidance and obtain any improvement permit, construction authorization, layout and soil evaluation from the local health department.
The portal includes permit, installation, repair, malfunction, private-well and underground-injection data. Data are incomplete and do not replace the local health department file. Permit pathways and site suitability depend on the property and proposed use. A nearby system or soil map is not approval for this parcel.

Review private well construction and permitting guidance; ask the local health department for records and water testing for the actual site.
Nearby well depth or yield does not prove an adequate or safe supply on this property. Confirm permits, construction and testing.

Screen state flood hazard layers and reports for the property and check map status.
Check effective FEMA maps and local floodplain rules. Preliminary or advisory data do not replace the effective panel or site-specific review.
Open official source : North Carolina Flood Risk Information System (opens in a new tab)FloodFEMA Map Service Center
Open the effective flood insurance rate map, study and revisions for the exact site.
Confirm the panel with the local floodplain administrator. Areas outside mapped special flood hazards can still flood.

Try opening the source in a new tab. It may be temporarily unavailable or require a browser security check.
Try FEMA’s effective flood map viewer. Confirm the panel and effective date; missing results do not establish that the property is outside a flood zone. You can also ask FEMA’s map specialists for help.
Keep this answer unknown until you can verify it. Save a note about what you still need to check. Opening a link or contacting an office does not confirm an answer.
GISNational Wetlands Inventory mapper
Screen wetlands and waterways before siting roads, fill, drainage or buildings.
This is a screening layer, not a field delineation or an agency permit decision.
Open official source : National Wetlands Inventory mapper (opens in a new tab)PlanningNC DEQ wetlands and buffer permitting
Check state water quality certification, wetland and riparian buffer requirements for proposed site work.
Mapped layers alone do not clear impacts to streams, wetlands or buffers. Confirm jurisdiction and permits for the actual work. Since December 5, 2025, submit federal Section 404 applications separately through the US Army Corps of Engineers Regulatory Request System (RRS); NC’s ePCN no longer transfers them. NC DEQ still accepts Section 401 applications through ePCN.

Soil maps do not replace a site evaluation or engineering review.

A practical Union County research sequence
County office directories are starting points. Zoning, deeds, septic, wells, flood, wetlands and access require current property-specific evidence.
- 1
Confirm the parcel and assessor
Screen NC OneMap, then find the county tax assessor or GIS office through the official county directory. Confirm the current tax map ID and record, then compare mapped shapes with deeds and a survey.
- 2
Ask who governs land use
Check county and municipal zoning, subdivision, roads, utilities, floodplain and any coastal requirements for the actual location.
- 3
Collect records and septic evidence
Request deeds, plats and easements from the register of deeds. Ask the local health department about onsite wastewater evaluation and permits.
- 4
Check water and mapped constraints
Review private well rules, effective flood mapping, wetlands, coastal requirements where applicable, soils and terrain; obtain site-specific confirmation.
Why Union County research still requires manual verification
NC OneMap aggregates county parcel data, while current assessment and recording access vary by county. Some records require registration, payment, a call or an in-person request. Confirm the current record, authority and site conditions.
Union County, North Carolina GIS and zoning questions
Where can I find Union County parcel information?
Screen NC OneMap's county-sourced parcel layer, then use the state county website directory to reach the tax assessor for current records. Neither source proves boundaries or adds automated LandGauge parcel coverage.
Does a tax parcel map prove the land can be built on or split?
No. Verify legal boundaries and access, then ask the county or municipality about legal-lot status, zoning, subdivision, roads, utilities and permits.
Where can I obtain deeds, plats and easements?
Find the county register of deeds through the state county website directory. Request the actual instruments and confirm dates, access and fees.
Who handles residential septic permits?
The local health department handles onsite wastewater improvement permits and construction authorizations under North Carolina rules. Obtain property-specific evaluation and permit records before relying on a proposed system.
Can a nearby well prove the parcel has water?
No. Contact the local health department about private well permitting and records. Confirm the actual well construction, water quality and supply for this site.
Does an empty flood or wetland map clear the site?
No. Check effective FEMA mapping and local floodplain rules, seek field review of wetlands, and ask NC DEQ about CAMA rules in a coastal county where relevant.
Turn the research into a property record
Start with North Carolina and Union County preselected. Add an address, parcel number or listing URL, then organize official findings, seller claims and open questions in one Property Review.
