Premier Construction & Design designs and builds accessory dwelling units and home additions throughout Liberty Lake. Our team manages zoning review, City of Liberty Lake permitting, structural design, and full build-out under one roof. Recent Washington legislation, including SB 6026, is driving real demand in Liberty Lake for ADUs, small multifamily conversions, and townhomes on lots that were single-family only a few years ago. We help owners read what their parcel now allows and build detached units and additions that fit the neighborhood's design standards instead of fighting them. 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.
