Premier Construction & Design designs and builds accessory dwelling units and home additions throughout Tri-Cities. Our team manages zoning review, City of Tri-Cities permitting, structural design, and full build-out under one roof. Higher-density infill is increasing across the Tri-Cities alongside the master-planned single-family growth, and ADUs fit both trends, whether housing family or contractors working Hanford Site cleanup. We manage zoning review and permitting in Kennewick, Pasco, or Richland, since each city handles it differently, and design units that work on the actual lot. Every project comes with transparent pricing, a clear timeline, and a one-year workmanship warranty.
If you receive a lower written bid from a licensed, bonded, and insured contractor for the same scope, materials, warranty, and timeline, we'll review it and match it where we can. Honest pricing, no games.
Bring us a qualifying written bid. We'll match it where we can, on residential projects under $25,000.
Applies to clearly defined-scope residential projects under $25,000 (before tax). Bid must be from a Washington-licensed, bonded, and insured contractor for identical materials, scope, warranty, and timeline.
