Chemung County, New York GIS, parcel, zoning and land-record resources
A county parcel map is a starting point for locating land and finding its public records. Use official New York and Chemung County paths to identify the local assessor, zoning authority and county clerk, 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
Chemung County research starts with its municipality and county clerk. New York's public statewide parcel GIS includes only counties that authorize sharing; a missing polygon does not mean no parcel exists. Confirm current tax assessment, local zoning, recorded rights, septic, water and environmental requirements separately.

Choose Chemung County and the exact city, town or village to find local assessment-roll and tax data.
Use the local assessor for current property-specific data. A tax roll does not establish survey boundaries, title or buildability.

Identify the governing city, town or village, then request its current zoning, subdivision and permit rules.
Zoning is a local inquiry. A county location or state guidance does not determine the applicable district for a parcel.

Review well contractor and completion-report requirements, then confirm records and water testing for the site.

Screen mapped freshwater wetlands, streams and other environmental resources.
DEC says the mapper does not display every regulated resource. Check current jurisdiction and any field delineation or permits with the agency.
Open official source : NYSDEC Environmental Resource Mapper (opens in a new tab)PlanningNYSDEC Freshwater Wetlands Program
Review current state wetland jurisdiction and permit guidance.
An empty map is not a wetland clearance. Following the April 8, 2026 court decision, DEC's current guidance requires applications for projects that impact previously mapped freshwater wetlands or wetlands of at least 12.4 acres. The statutory size threshold is scheduled to decrease to 7.4 acres on January 1, 2028. Request a DEC jurisdictional determination rather than rely on the mapper. Determinations issued January 1, 2025 through April 8, 2026 may qualify for reassessment; ask DEC to review eligibility. State and federal rules may require separate review.

A practical Chemung County research sequence
Maps and directories are starting points. Confirm current recorded rights, zoning, access, utilities, flood, wetlands and approvals with property-specific evidence.
- 1
Match assessment and recorded documents
Choose the county and exact city, town or village in the state assessment portal. Compare identifiers with county clerk deeds, filed maps, easements and a current survey.
- 2
Ask the governing local planning office
Confirm the current zoning, legal lot status, subdivision, frontage, access, roads and utilities with the applicable city, town or village.
- 3
Verify septic and private water if proposed
Ask the local health authority about onsite wastewater records, testing and approvals. Check well completion records and water quality where private water is proposed.
- 4
Screen flood and wetlands
Check effective FEMA maps, NYSDEC wetland resources and local restrictions, then confirm parcel-specific conditions and permits.
Why Chemung County research still requires manual verification
Local assessors maintain tax records, city/town/village officials govern zoning, and county clerks maintain recorded documents. Public statewide parcel geometry is available only from sharing counties. Health, water and environmental decisions need separate site-specific confirmation.
Chemung County, New York GIS and zoning questions
Where do I find Chemung County property and tax information?
Choose the county and the actual city, town or village in the NYS municipal assessment portal and confirm current records with its assessor. The statewide public parcel GIS includes only sharing counties; absence from that layer is not proof that a parcel is missing.
Who decides zoning and subdivision?
Ask the property's governing city, town or village for the current ordinance, map, legal lot status, frontage, access and proposed-use requirements.
Where do I check deeds and easements?
Contact the Chemung County clerk for actual recorded instruments and filed maps; compare them with professional title and survey work.
Who handles septic and wells?
Check local health and applicable state standards for onsite wastewater. NYSDEC's well program has completion reporting; confirm any property-specific well records, yield and water testing.
How do I check wetlands and flood risk?
Screen NYSDEC's resources and effective FEMA maps, then ask the relevant agency and local office. A blank map is not a jurisdictional or flood-safety determination.
