Any racking system that penetrates the ground would need a soils study to avoid a forest of posts with concrete. Without a soils study the assumption is the ground has the consistency of beach sand. We did not have the time for a soils study. Therefore I suggested a ballasted ground mount.</span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,"sans-serif"">The AHJ favors \u201cpre-engineered, ready-to-use\u201d designs (their quote). Unirac provides this service for their RM10EVO product and also stipulates approval for ground mounting. We entered the information into the U-Builder web portal, including a California address, and received an engineering report certifying a design with the required parts and ballast blocks.</span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,"sans-serif"">The AHJ failed to recognize this as a pre-engineered, ready-to-use design and called for a wet-stamped engineering report. For a mere $350 Unirac offered to provide this, a fair price. In the process of requesting this report we were informed that the California code cycle had updated on 1/1/2026 and new standards are in place. The old standard is ASCE7-16. The new one is ASCE 7-22. Unirac told me that they have yet to be certified for 7-22 for the RM10EVO. Oddly the U-builder report states compliance with 7-22 but apparently this is an error. Unirac will not provide a wet-stamp certifying compliance with 7-22 and the 2025 California Residential Code and/or the 2025 California Building Code.</span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,"sans-serif"">I write this for two reasons: 1.
