Solar PV electrical permit with zoning or plumbing permits when applicable
Denver's solar permit guide says all solar systems require an electrical permit. A zoning permit is required when panels are not flush with the roof or when an exterior generator or battery backup system is part of the project, and a plumbing permit is required for all solar hot water systems. Some eligible single-family and duplex PV projects can use SolarAPP+ and an electrical quick permit.
