Streamline Design & Permitting was founded in 2022 by Devin Way, its CEO and managing partner, and reports more than 45 successfully permitted projects across San Diego County. Its office is at 500 La Terraza Blvd., Suite 150, Escondido, CA 92025; phone (858) 588-3433; hours Monday to Friday, 9:00 AM to 5:00 PM. It serves most of San Diego County, except Chula Vista, Lemon Grove, La Mesa and Coronado, as well as Riverside, Orange and Los Angeles counties.
