Do I need a permit for solar panel installation in Richardson?
Yes. In Texas, solar panel installation generally requires a permit, and Richardson is no exception.
Texas cities require both a building and an electrical permit for a rooftop solar system, and utilities such as Austin Energy require a separate interconnection approval in addition to the city permit. Ground-mount and building-integrated (solar-shingle) systems face additional plan-review and engineering requirements beyond a standard roof-mount array. Confirm scope with the local building department and your utility. Richardson requires a building permit for a residential solar installation to check the loading on the existing roof system, the electrical tie-in and any battery system. Additional loading on the original roof framing requires an engineered letter and/or a framing diagram, and the permit fee is a minimum of $50 or one percent of the total job cost, whichever is higher. The building permit must be approved and posted at the property before work begins, and the installer must be registered to work in Richardson with a state-licensed electrician for the electrical work.
