Premier Construction & Design designs and builds accessory dwelling units and home additions throughout Sunnyside. Our team manages zoning review, City of Sunnyside permitting, structural design, and full build-out under one roof. Sunnyside's young median age and multigenerational households make in-law suites, ADUs, and room additions genuinely practical here rather than speculative. We manage zoning review and permitting, and design additions that keep the family together on one property instead of forcing a move. 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.
