Eureka County has no standalone ADU ordinance. Accessory dwelling units are permitted only as a function of the underlying zoning district under Eureka County Code Title 9. In rural residential and agricultural districts (the majority of the county), one accessory dwelling, guest house, or 'mother-in-law' unit is generally allowed by right on a single parcel subject to setbacks, well/septic capacity, and the 1,000 sq ft typical accessory-structure ceiling. There is no county-specific size cap, owner-occupancy clause, or impact-fee schedule beyond standard building permit fees. Nevada has no statewide ADU-preemption law (no equivalent to California SB 9 / SB 13), so the county's silence on ADUs means parcels are governed by the general accessory-dwelling provisions of the underlying zone.

• wui-fire-zone — There is no county-imposed fee for WUI compliance; defensible-space inspections are voluntary and offered at no cost by NDF on request.
• flood-zone — FEMA FIRM panels for Eureka County were last updated in the early 2010s; check the MSC portal for the current effective panel before designing in a flood-prone parcel.
• other — Most residential parcels are well clear of active mining footprints, but title work should confirm any mineral-rights severance before an ADU is sited near a historic district.
