Grapevine, TX Solar Energy: Panel Permits (2026)

Solar PV installations in Grapevine require a combined building and electrical permit from the Grapevine Building Inspections Division. Submittal materials typically include a site plan, roof plan showing panel placement and setbacks from roof edges and ridges, structural analysis confirming the existing roof can carry the additional dead load, a single-line electrical diagram, manufacturer specifications for panels and inverters, and a layout showing rapid shutdown devices required by NEC 690.12. Code compliance follows the 2021 IRC, 2020 NEC (or current adopted cycle), and IFC fire access rules. Fire access pathways typically require a 3-foot clear pathway at the ridge and along sides of the roof for firefighter access, with some flexibility based on roof geometry. Ground-mounted solar is permitted as an accessory structure subject to setback and screening requirements. Grapevine's net metering interconnection is through Oncor, the regulated utility covering most of the city; the utility handles meter changes and interconnection agreements after city inspection is complete. Permit fees are based on job valuation. Typical permit turnaround is 7 to 14 business days. HOA approval is often required separately; however, Texas Property Code Section 202.010 limits HOAs from prohibiting solar devices on single-family homes, allowing only reasonable restrictions.
