Do I need a permit for a remodel in Seattle?
In Seattle, you need SDCI permits for any work involving structural changes, plumbing modifications, new electrical circuits, or ventilation changes. You do NOT need a permit for cosmetic work like painting, cabinet replacement (same location), re-tiling, or fixture swaps in the same location — as long as all work stays under $6,000 within 6 months. SDCI permit fees increased 18% in 2026. Source: Seattle SDCI.
What is the sales tax on remodeling in Washington state?
Washington charges sales tax on BOTH construction labor AND materials. Seattle's combined rate is 10.55% (state 6.5% + local 4.05%). This applies to the total contract amount including labor, materials, contractor profit, subcontractor charges, and even permit fees passed through to the customer. Bellevue/Eastside: 10.4%. Tacoma: 10.3%. This is a significant cost many homeowners overlook. Source: WA Department of Revenue.
What is the best ROI for a home remodel?
According to the 2025 Zonda/JLC Cost vs. Value Report, minor midrange kitchen remodels return 112.9% ROI — the highest of any remodeling project. Other strong returns: fiber-cement siding (113.7%), garage door replacement (268%), and midrange bathroom remodel (80-91% in the Pacific region). The key is targeting mid-range over luxury: mid-range remodels consistently deliver better ROI than upscale ones. The Pacific region (including Seattle) outperforms all other U.S. regions.
How long does a remodel take in Seattle?
Timelines vary by scope: Kitchen — 4-6 weeks (cosmetic) to 14-20+ weeks (major custom). Bathroom — 3-4 weeks (standard) to 6-8 weeks (primary suite). Basement — 2-4 months. Home addition — 4-12 months. Whole-home — 6-16 months construction plus 2-6 months design. Add 2-8 weeks for SDCI permit review (currently at 64-day 75th percentile for residential projects). Cabinet lead times can add up to 16 weeks. Sources: Iconic Cabinetry, CRD Design Build, SDCI.
How can I save money on a remodel in Seattle?
Key strategies: (1) Keep existing layout — moving plumbing or walls adds $5K-$15K+. (2) Choose mid-range materials — quartz over marble saves $50-$100/sf. (3) Keep appliances if under 10 years old. (4) Work with a design-build firm like Giant Builders to avoid separate architect fees and markups. (5) Time your project for slower seasons (fall/winter). (6) Get multiple quotes but avoid lowest bidders. Giant Builders delivers 15-20% below market through efficient project management and established supplier relationships.
