Permit approval in Las Vegas generally takes 2 to 6 weeks depending on project complexity. Simple residential alterations may clear review faster, while projects requiring structural, electrical, and plumbing plan reviews go through multiple departments. Incomplete applications are the most common cause of delays at the building department. As of July 2025, the City of Las Vegas and Clark County have slightly different timelines and submission requirements, so knowing which jurisdiction applies to your property matters. Kingdom and Co. maintains strong relationships with local architects, engineers, and city officials, which helps streamline the permitting process.
