What Port St. Lucie expects on a solar permit
Permit applications must account for a 160 mph wind speed and Exposure Category B, following Risk Category II per FBC 2023 and ASCE 7-22. The jurisdiction requires digital submission and a rapid shutdown pathway placard. A post-installation Engineer Letter of Compliance sealed by a Florida-licensed PE is mandatory. This letter must verify a minimum 3-inch lag screw embedment into roof trusses and confirm the inspection of all solar attachment connection points and waterproofing. The documentation must include the AHJ permit number, inspection date, and the name of the third-party inspector.
- [structural] Requires structural design and wind load calculations based on 160 mph wind speed, Exposure Category B, Risk Category II, per FBC 2023 and ASCE 7-22.
- [structural] Requires a post-installation Engineer Letter of Compliance (Special Inspection) sealed by a Florida-licensed PE that explicitly verifies a minimum 3-inch lag screw embedment into roof trusses.
- [documentation] The Engineer Letter of Compliance (or Special Inspection Affidavit) must explicitly list the AHJ permit number, the date of the inspection, and the specific name of the 3rd-party inspector.
- [structural] The Engineer Letter of Compliance must specifically address solar attachments, confirming inspection of all connection points (panel-to-rack, rack-to-mount, mount-to-structure) and waterproofing, rather than using a standard roof-only form.
