Summary
Operating as an electrical contractor in San Antonio requires both state licensing through the Texas Department of Licensing and Regulation and local permit compliance through the city's Development Services Department. Contractors must hold either a Master Electrician License or employ a licensed Master Electrician, maintain proper insurance coverage, and obtain permits for virtually all electrical work except basic maintenance. The city follows the 2020 National Electrical Code and requires multiple inspections throughout most electrical projects. Successful electrical contractors in San Antonio typically invest in proper licensing, insurance, and permit processes upfront, as the city actively enforces electrical codes and non-compliance can result in stop-work orders and significant penalties.
