A copy of this form shall be attached to each of TWO sets of plans, of minimum 11” x 17” size. If answering NO to any of the questions, plan check shall be required. Project Address: Contractor Company Name: Contractor License Number: YES NO Are the following applicable to the proposed project? 1.   Will the PV system layout provide the required three-foot wide clear access pathways per Section 605.11 of the California Fire Code, and is this shown on the roof plan? 2.   Will the PV system be installed on a roof having only one roofing layer with no overlays? 3.   Will the PV array be flush mounted to the existing roof so that the plane of the modules (panels) are parallel to the plane of the roof? 4.   Will the PV system weigh maximum 4 pounds per square feet or less? 5.   Will the PV system be installed where the modules do not overhang any roof edges (such as eaves, gabled ends, ridges and hips)? 6.   Will the PV system be installed with a space of 2” minimum to 10” maximum between the underside of modules and the surface of the roof? 7.   Will the PV system be installed without using any ballast system or counter-weight system? 8.   Will the anchors be installed with a maximum horizontal anchor spacing of 6 feet and is this maximum horizontal spacing shown on the plans? 9.   Will the minimum 5/16” lag screws be installed with a minimum of 2-1/2 inch embedment into roof rafters (with pre-drilled holes) and is this minimum embedment shown on the plans? 10.   Are ALL the structural pages of the plans stamped and signed by a California licensed professional engineer? (including project specific site plan, PV layout, anchorage spacing, anchorage details and manufacturer’s PV support information.)
