This guide explains the typical permit path, who enforces the rules, how to apply, and where to find forms and interconnection steps so you can plan installation with regulatory compliance and maximize available rebates.

Permits & Overview

Most residential photovoltaic (PV) systems require a building permit and an electrical permit in San Antonio; installers typically submit structural and electrical plans for review before issuance. For interconnection and utility-side requirements you must follow CPS Energy procedures for distributed generation and net metering or buyback terms. [1] [2]

Confirm permit checklist with your installer before payment.
