About This Market

UPDATED APR 2026

Lewiston's general contracting market runs hot and cold with the seasons. You've got steady residential remodel work year-round - older housing stock means constant kitchen and bath updates, roof replacements, additions. Commercial work centers around agriculture, healthcare, and some light industrial. Material costs hit hard here - you're trucking everything up from Boise or over from Spokane. Labor's tight, especially skilled trades. Competition's manageable with about 15-20 established GCs, but the good crews stay busy.

Get your Idaho Public Works license sorted first - the exam's no joke and processing takes 4-6 weeks. Lewiston Building Department knows their stuff, but they're reasonable if you submit clean plans. Build relationships with the inspectors early. Plan your big jobs for spring through fall - winter weather shuts down exterior work November through March. Keep 2-3 months operating capital on hand because payment cycles stretch in this market. Local supply houses will work with you, but establish credit before you need it.
