When a permit is required
Permit triggers and exempt work for Washington County
County permit pages and the homeowner process guide indicate permits are required for normal building construction, alterations, additions, and related work in unincorporated areas, with separate review triggers for stormwater, grading, fire systems, and related site work. The stormwater program page says land disturbance over 5,000 square feet requires stormwater management approval and a grading permit.
Note: No consolidated county exempt-work list was clearly published in the retrieved county materials.
