Local context for Seattle
Seattle permits are issued by the Seattle Department of Construction and Inspections (SDCI) through the Seattle Services Portal. Seattle enforces the 2021 Seattle Energy Code, which effectively eliminates fossil fuels for most space and water heating in new commercial and multifamily construction and requires electrification readiness on all new construction. Seattle also sits in high seismic zone D with specific lateral-bracing amendments.

Several local factors push Seattle bathroom remodel pricing above or below the national baseline:
Can I install a gas furnace in a new Seattle home?
The 2021 Seattle Energy Code effectively requires heat pumps for space heating in most new construction. Gas is still allowed in existing homes for replacement, but new construction has to meet the all-electric or equivalent performance paths.
Do I need a permit to cut down a tree on my Seattle property?
Often yes. Seattle Municipal Code 25.11 protects Exceptional Trees and many Tier 2 trees based on species and size. SDCI and the Office of the Tree Service Provider Registration handle approval. Removing a protected tree without approval can trigger fines and replacement requirements.

Walk-in showers ($5,000-$10,000) are the most popular choice for primary bathrooms in 2026. Tub/shower combos ($2,500-$4,000) are better for families with small children. Keep at least one tub in the house for resale.
For cosmetic changes: no. For any plumbing modifications, electrical changes, or structural work: yes. Most mid-range and major bathroom remodels require permits.
Yes. Demo (removing old tile, vanity, toilet) is easy DIY that saves $500-$1,500. Painting is another easy save. Leave plumbing, electrical, tile setting, and waterproofing to professionals.
