Key factors affecting your room addition cost in Sun Valley:

The lower end applies to simple single-story additions with standard finishes; the upper end reflects additions with complex roof integration, bathroom plumbing, or premium finish specifications.
All room additions in Sun Valley require permits covering structural, electrical, plumbing, and mechanical work. The permit process typically takes 4–8 weeks for approval. APLA Construction manages the entire permit process — including plan preparation coordination, city submission, and all required inspections. We never begin structural work without proper permits in place.
