Installing a propane generator without the proper permits in Puerto Rico is illegal and creates serious liability. It can also void your homeowner's insurance and create problems when selling your property. This guide explains exactly which permits you need and how to get them.
Why Permits Matter
Propane generator installations involve three regulated systems, the propane fuel system, the electrical transfer switch, and the structural pad. Each falls under different regulatory agencies in Puerto Rico, each with its own permit process.
⚠️ Warning: Never hire a contractor who suggests skipping permits. That is a major red flag for unlicensed work and puts your home at risk.
