THE CONTRACTOR/INSTALLER OF THE SOLAR PV SYSTEM OVER EXISTING ROOF SHALL CONFIRM TO OSHA REQUIREMENTS DURING THE CONSTRUCTION PHASE. JOB SAFETY AND CONSTRUCTION PROCEDURES ARE THE SOLE RESPONSIBILITY OF THE CONTRACTOR/INSTALLER. 2. IN CASE OF CONFLICT BETWEEN STRUCTURAL DRAWINGS AND ELECTRICAL DRAWINGS, THE MOST RIGID REQUIREMENTS SHALL GOVERN. 3. THE CONTRACTOR/INSTALLER SHALL VERIFY ALL EXISTING BUILDING INFORMATION SHOWN (DIMENSIONS, ROOF TOP PROJECTIONS, ETC.) AND NOTIFY THE ENGINEER OF ANY DISCREPANCIES PRIOR TO INSTALLATIONS OF PV SYSTEM. 4. THE CONTRACTOR/INSTALLER SHALL VERIFY AND COORDINATE EXISTING OPENINGS, ROOF TOP UNITS, VENT PIPES, ETC. SHOWN ON DRAWINGS. IF THERE IS A DISCREPANCY BETWEEN DRAWINGS, IT IS THE CONTRACTORS/INSTALLER'S RESPONSIBILITY TO NOTIFY ENGINEER PRIOR TO PERFORMING THE WORK. 5. ALL CONSTRUCTION IS TO BE PERFORMED IN STRICT CONFORMANCE WITH ALL APPLICABLE TOWN,COUNTY & STATE REGULATIONS AND/OR ANY OTHER GOVERNING BODIES. 6. DO NOT SCALE THESE DRAWINGS, USE DIMENSIONS. CONTRACTOR MUST CONDUCT ROOF SURVEY TO VERIFY DIMENSIONS SHOWN ON PLAN PRIOR TO INSTALLATION. IF THERE IS A DISCREPANCY IT IS CONTRACTOR/INSTALLER'S RESPONSIBILITY TO NOTIFY THE ENGINEER IMMEDIATELY. 7. EACH MODULE TO BE GROUNDED USING THE SUPPLIED CONNECTION POINT PER MANUFACTURER'S REQUIREMENTS. ALL SOLAR MODULES, EQUIPMENT, AND METALLIC COMPONENTS ARE TO BE BONDED. IF THE EXISTING GROUNDING ELECTRODE SYSTEM CAN NOT BE VERIFIED OR IS ONLY METALLIC WATER PIPING, IT IS THE CONTRACTOR'S RESPONSIBILITY TO INSTALL A SUPPLEMENTAL GROUNDING ELECTRODE. 8. ALL PLAQUES AND SIGNAGE REQUIRED BY THE LATEST EDITION OF NATIONAL ELECTRICAL CODE. LABEL SHALL BE METALLIC OR PLASTIC, ENGRAVED OR MACHINE PRINTED IN A CONTRASTING COLOR TO THE PLAQUE. PLAQUE SHALL BE UV RESISTANT IF EXPOSED TO SUNLIGHT. 9. DC CONDUCTORS SHALL BE RUN IN RMC AND SHALL BE LABELED, "CAUTION DC CIRCUIT" OR EQUIV. EVERY 5 FT. 10. EXPOSED NON-CURRENT CARRYING METAL PARTS OF ELECTRICAL EQUIPMENT SHALL BE GROUNDED IN ACCORDANCE WITH 250.134 OR 250.136(A). 11. CONFIRM LINE SIDE VOLTAGE AT ELECTRIC UTILITY SERVICE PRIOR TO CONNECTING INVERTER. VERIFY SERVICE VOLTAGE IS WITHIN INVERTER VOLTAGE OPERATIONAL RANGE. 12. OUTDOOR EQUIPMENT SHALL BE NEMA-3R RATED OR BETTER. 13. ELECTRICAL CONTRACTOR TO PROVIDE CONDUIT EXPANSION JOINTS AND ANCHOR CONDUIT RUNS AS REQUIRED PER NEC. 14. ALL WIRING MUST BE PROPERLY SUPPORTED BY DEVICES OR MECHANICAL MEANS DESIGNED AND LISTED FOR SUCH USE, AND FOR ROOF-MOUNTED SYSTEMS, WIRING MUST BE PERMANENTLY AND COMPLETELY HELP OFF OF THE ROOF SURFACE. CEC 110.2 - 110.4 / 300.4 15. ALL ROOF PENETRATIONS MUST BE FLASHED. SIMPLY CAULKING DOES NOT SUFFICE. 16. PV INSTALLATION SHALL COMPLY WITH ARTICLE 690 OF 2022 CEC, CRC REQUIRES THAT SMOKE ALARMS AND CARBON MONOXIDE ALARMS ARE RETROFITTED INTO EXISTING DWELLING, THE REQUIRED SMOKE ALARMS AND CARBON MONOXIDE DETECTORS SHALL BE LOCATED AS REQUIRED PER SECTION R314 & R315 WITHIN THE CALIFORNIA RESIDENTIAL CODE. 17.

All review is based on these observations and the design criteria listed below and only deemed valid if the provided information is true and accurate. The scope of this report is strictly limited to an evaluation of the fastener attachment, underlying framing, and supporting structure with the additional loading due to the installation of the solar PV panels. The design of racking (rail spans, mounting hardware, etc.), PV panels and all other structure is by others and shall be per the specified design criteria. Laguna Consulting Engineers assumes no responsibility for improper installation of PV panels, racking, or waterproofing. Prior to starting construction, contractor shall verify the framing sizes, spacings, and spans noted in the stamped plans and this letter and notify the Engineer of Record of any discrepancies noted. This review relies on the roof’s structural system having been originally designed and constructed in accordance with the building code requirements and having been maintained to be in good condition.  ROOF 1: Adequate to support the imposed loading - No structural upgrades required Page 1 12/31/25       HISTORIC-825 N Lacy St2/18/2025 Project: Location: GRAVITY LOADS (ROOF 1) 2.63 psf Note: PV System Weight Provided by Client/ Manuf.
