Restoration work $1,000+ needs an NSCB license; no state mold license
In Nevada, only repair or maintenance work valued at less than $1,000 (combined labor and materials) is exempt from contractor licensing under NRS 624.031 — and even that exemption does not apply when a building permit is required or the job falls in a licensed classification that affects public health and safety. Restoration, structural repair and remodeling at or above that threshold must be performed by a contractor licensed by the Nevada State Contractors Board (NSCB). Nevada does not issue a separate mold-remediation license, so mold work is regulated through the Board's general contractor classifications rather than a mold-specific credential. Reno-area (Northern Nevada) office: 775-688-1141 (Southern Nevada: 702-486-1100); verify any license at nvcontractorsboard.com.
