Deck Construction · Clark County, Washington
Permit required
In Washington, a Deck Construction requires a building permit.
The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit. Plans are reviewed under the Statewide code (IRC 2021); apply through Clark County Building Department before work begins.

Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).
As one of the more densely populated areas in Washington, Clark County (around 516,959 residents) tends to see higher application volumes at its building department, so it helps to prepare your documentation in advance.
Code Compliance & Inspections
Under Washington seismic provisions, structural plans are reviewed for retrofitting and shear-wall integrity to comply with the Washington State Building Code.
Concurrent Permits & HOAs
For Clark County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Deck Construction than the county itself.
Zoning & Cost Factors
Washington operates under the Growth Management Act (GMA), requiring fast-growing counties to adopt comprehensive plans to manage density and protect critical areas. Fortunately, Washington maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Yes. Washington generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Washington State Building Code.
