Choosing a Home Addition Contractor:

Whether it's an attached home addition, a second story home addition, sunroom, detached garage or other house addition, you need to consider effects on the existing structure, your timetable, current local building codes and home owner association restrictions. Having a contractor experienced in additions, remodeling, and new construction will be invaluable in the process of adding on to your home. It's a great idea to get suggestions from various contractors; but when getting estimates make sure you know exactly what work will be done, including materials, labor, and other services such permits and plans. All contractors on this site are licensed and bonded, but should you use another contractor, be sure to verify their Washington State Contractor's License.

Quick Tip: People are often surprised by changes or limitaions of local building codes when they want to expand their home. Be prepared to be flexible or make changes in your home addition plans.
