The Seattle, WA Local Code Shield
Professional landscapers in Seattle must maintain a valid Washington State Contractor License and adhere strictly to the Seattle Department of Construction and Inspections (SDCI) codes regarding erosion control. Compliance with the Seattle Stormwater Code is non-negotiable, as improper grading can lead to significant environmental fines. A qualified contractor will always provide proof of their Unified Business Identifier (UBI) and demonstrate a clear understanding of local tree protection ordinances for heritage trees.
