Residential and remodel projects

In Clark County, you need permits and follow-up inspections for new residential construction and for most additions and remodeling projects. A permit technician can help you determine your project requirements and related fees.

Fees are established by county ordinance and are calculated automatically by computer during the application process. You will receive a fee estimate during your initial visit to our office and a final cost when you submit your application. Permit fees cover the cost of processing, plan review and inspections.

Decks - Decks more than 30 inches above grade require a building permit. All decks must meet minimum setback requirements and be constructed to building code standards even if a permit is not required.

Fences - Fences less than six feet in height do not require a permit.

Garden sheds, tool sheds, and play structures - Structures less than 200 square feet do not require a permit.

Lawn sprinklers - A permit is required for the backflow prevention between the sprinklers and the water supply.

Retaining walls - A permit is required for retaining walls over four feet in height, when measured from the bottom of the footing to the top of the wall, and/or for walls that support a load (i.e. slope, driveway, footings). Engineering by a Washington State registered engineer is required for all retaining walls requiring a permit.

Roofing - Re-roofing permits are required for all buildings in Clark County. A separate permit may be required if structural work such as replacing roof sheathing is necessary. Generally, a maximum of two layers of roofing may be applied to a residential structure.   

Siding and windows - A permit is required to replace any windows or siding on a structure.

If your project involves electrical work, connection to public water or sewer, or connection to an existing septic system, you will need additional permits and approvals from other agencies.
