Washington County Building Permits & Rules
Building permits in Washington County, Minnesota are required for most structural work, additions, decks over a set height, electrical panel changes, and new construction.
Frost-depth footings are a standard local requirement so structures do not heave over winter. In most cases your contractor pulls the permit and schedules the inspections.
For exact fees and forms, check with the Washington County offices before you start. A vetted local contractor can handle the permit process for your project.
