Residential projects

Body

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.
