Counties in North Dakota

What zipradar surfaces at the North Dakota county level

County governments — not states or the federal government — own four of the most decision-relevant neighborhood-data layers. zipradar federates each from its authoritative public source, refreshed on the cadence each agency publishes.

Property tax

North Dakota county assessors publish parcel-level millage rates and assessed values. zipradar federates the county-by-county tax structure so a buyer can compare effective tax burden across North Dakota's 2 counties. Annual reassessment cadence; check each county for the most recent reassessment year.

Deed activity

County recorders log every property transfer. zipradar surfaces aggregated deed activity (count of recent transfers, median sale price ranges) at the ZIP level, never owner names or PII. Daily filings; published with a 1-2 day recorder lag.

Radon zones

The EPA Map of Radon Zones classifies every US county into Zone 1 (highest risk), Zone 2 (moderate), or Zone 3 (lowest). The 1993 baseline is overlaid with state-level radon survey data when published. zipradar shows the zone designation for each North Dakota county.

Sex offender registry

County and state registries are linked in real time via the National Sex Offender Public Website (NSOPW). zipradar deep-links to the official registry — never caches personal records — so privacy statutes are honored at the source.
