Home addition contractor in Bothell, WA

Bothell project planning

Plan home additions around the actual property.

Bothell spans King and Snohomish counties. Verify city boundaries for the property and then confirm which agency handles each permit; county location alone does not determine the building-review authority for an incorporated parcel.

Test the proposed footprint against the site before developing a detailed room plan. A larger room needs a practical foundation and roof connection, a workable utility strategy, and a construction sequence around the retained house.

• Parcel boundaries, existing improvements, and the buildable footprint
• Foundation, load paths, roof tie-in, and drainage
• Heating, electrical, plumbing, and energy-performance requirements
• Connections to retained rooms and temporary weather protection
