Mansfield, TX Solar Energy: Panel Permits (2026)

Mansfield requires permits for residential and commercial solar photovoltaic installations. Applications typically include site plan, structural calculations showing roof-loading capacity, single-line electrical diagrams, manufacturer spec sheets, and interconnection agreement with Oncor or ONCOR-affiliated retail electric provider. The adopted International Residential Code and International Fire Code require fire access pathways on pitched roofs, typically 3-foot clear paths on each side of the ridge and a 3-foot setback from ridges and valleys. Ground-mount arrays must meet zoning setbacks and screening requirements. Licensed electricians and roofers must perform the work, though a homeowner exemption applies when the owner occupies the home. After installation, Mansfield inspectors verify building, electrical, and fire code compliance. Once approved, the utility installs a net meter and commissions the system. Permit fees are based on project valuation. Contact Building Inspections at (817) 276-4200 for specific requirements.
