Hunterdon County · Califon Borough
Califon Real Estate
A compact housing market with historic village homes, river proximity, limited inventory and important historic-preservation considerations.
Califon began a municipal-wide property revaluation in 2026. New assessments are scheduled to be used for 2027 taxes, so owners and buyers should verify current assessment information directly with the borough.
Understanding Califon Property
Historic Village Homes
Much of Califon’s visual identity comes from nineteenth-century and early twentieth-century homes within or near the historic district.
Small Municipal Footprint
With less than one square mile inside the borough, the number of properties and active listings is naturally limited compared with surrounding townships.
Walkability & Trail Access
Proximity to Main Street, the Columbia Trail, Island Park and the South Branch Raritan River can be an important lifestyle consideration.
2026 Property Revaluation
The Borough announced that a full property revaluation began in 2026 after being mandated by the Hunterdon County Board of Taxation. The new assessments are expected to be used for 2027 property taxes.
Historic-District Due Diligence
Before Exterior Work
Review Califon’s historic-preservation guidelines and current zoning requirements before planning major exterior changes, additions or demolition.
Before Purchase
Confirm whether the property lies within the historic district, what approvals may apply, and whether prior improvements have appropriate permits.
Buyer & Owner Checklist
- Confirm the property is actually in Califon Borough rather than simply using a Califon 07830 mailing address.
- Review the current tax assessment and 2026–27 revaluation status.
- Check flood, river, drainage and insurance considerations for properties near the South Branch Raritan River.
- Verify zoning, permitted uses, septic/sewer and utility information directly with the appropriate authority.
- For historic properties, distinguish charming original features from deferred maintenance that may require specialized work.
