Public-record contractor profile
Legal record: DESIGN BY OZ LLC
Why this profile appears
Design By Oz LLC is included because 4 selected Seattle construction permits explicitly describe retaining-wall, rockery, slope, drainage, foundation, or closely related site work. The records span Aug 21, 2023 through Sep 5, 2025 and place the documented work in Mount Baker, Briarcliff, Leschi and Stevens.
The most recent selected record is permit 6958535-CN, issued Sep 5, 2025 in Mount Baker. Its public scope says: “Construct exterior deck addition and retaining walls and associated sitework for single-family residence per plan.”
Across the current exact SDCI dataset responses and manually checked Seattle Services Portal records, 3 of 4 selected records have a matching legal name, listed L&I principal, or Portal contractor license. 1 record does not currently publish a contractor identity. The status for every project is shown below.
Permit scope, dates, status, and cost come from the exact official rows. A permit without a reproducible contractor identity—through the published name or a separately checked Portal license—should be treated as a research lead, not proof that DESIGN BY OZ LLC performed that work. The profile also does not establish current availability, design responsibility, workmanship, customer satisfaction, or suitability for another property.
Quick read
