- Structural certification report required verifying the existing roof framing safely supports the array, using Mesa County's PV-specific design criteria: 115 mph wind speed and snow loads by elevation per the Adopted Codes and Regulations page
- Three-line diagram required showing all conductor sizing and insulation types, overcurrent protective devices, and conduit sizing/types
- Documentation required: source connection type used; method for determining required busbar ampere rating; specification sheets for all listed compatible components; roof layout showing access, pathways, ridge setback, total roof area, and total array area (sq ft)
- DC circuits in buildings require metal raceways and labeling as 'PHOTOVOLTAIC POWER SOURCE'
- A rapid shutdown function to reduce firefighter shock hazard is required
- All commercial and ground-mount PV system designs require structural, foundation, and electrical drawings stamped and signed by a Colorado Professional Engineer

Tips
- Verify current code edition with the Building Department before submittal — the standalone Photovoltaic Guide (7/20/2023) still lists 2018 IBC/IRC/IEBC/IFC and 2023 NEC, which predates the County's September 1, 2025 move to the 2024 IBC/IRC/IEBC cycle documented on the Adopted Codes page.
- The PV-specific structural design wind speed (115 mph) is HIGHER than the general Grand Junction-area residential wind speed (104 mph) used for ordinary construction — use the PV Guide's 115 mph figure for solar mounting structural certification.
- Grand Junction roof-mount solar does NOT require a separate City planning clearance under the PV Guide's stated policy (unlike De Beque, Collbran, and Palisade) — but ground-mount systems DO require one regardless of jurisdiction, and commercial systems require a City planning and fire clearance.
Frequently asked questions
- Do I need a City of Grand Junction planning clearance for a rooftop solar installation?
- No, per the Mesa County Photovoltaic Guide, residential roof-mount systems only require a City planning clearance if installed in De Beque, Collbran, or Palisade — not in Grand Junction. However, ground-mount residential systems require a planning clearance regardless of jurisdiction, and commercial systems within Grand Junction city limits require a City planning and fire clearance.
