Washington Compliance

Detailed for Washington, not adapted to it

Washington projects often require drawing sets shaped by local city and county review, state energy expectations, seismic and lateral detailing, heavy rain and stormwater conditions, shoreline and critical-area rules, wildfire-interface exposure, mountain snow loads, sloped lots, and site-specific AHJ requirements.
Every Cadgency set is prepared with Washington permitting in mind. We organize plans, elevations, structural notes, roof framing, foundation details, site references, schedules, and revision responses so residential and light commercial projects move through review with fewer avoidable comments.

FAQ

Washington questions, answered

Many structural scopes, additions, commercial improvements, engineered decks, foundation changes, lateral-system updates, and certain municipal submittals may require a Washington-licensed professional depending on project type, location, and AHJ requirements. Cadgency prepares the drawing set and coordinates sealing where needed.

Yes. We prepare Washington permit drawings for Seattle-area remodels, Puget Sound shoreline properties, mountain cabins, snow-load regions, wildfire-interface sites, ADUs, older homes, decks, garages, tenant improvements, light commercial projects, as-builts, and plan-review corrections.

Typical residential permit sets run 5 to 10 business days depending on scope, existing information, structural requirements, city or county review standards, seismic coordination, shoreline or critical-area notes, drainage conditions, snow-load requirements, and revision needs. Smaller as-builts and red-line updates are often faster.

Whatever you have: sketches, photos, old plans, site photos, survey information, municipal comments, zoning notes, shoreline or critical-area details, slope or drainage concerns, foundation notes, or a basic description of what you want to build. We turn that information into a clean Washington-ready permit set.
