Full Breakdown
Richardson requires a combined building and electrical permit for all photovoltaic (PV) solar installations on residential roofs. Applications must include a site plan, one-line electrical diagram, equipment specification sheets, and a structural analysis showing the existing roof can support the added dead load, typically 3-5 pounds per square foot. Installations must comply with the 2021 International Residential Code, 2020 National Electrical Code Article 690, and the 2021 International Fire Code rooftop access requirements, including a 3-foot-wide access pathway along at least one ridge and clear setbacks from roof edges on hip roofs. A licensed Texas electrical contractor must perform the electrical work, and final inspections by both building and electrical inspectors are required before Oncor will issue permission to operate. Ground-mount systems also require a permit and must meet accessory structure setbacks.
