I got some responses from the manufacturer of the SIP panels, with answers to my satisfaction. Premier also suggested I apply for the Los Angeles building permit now at the Department of Building and Safety (LADBS), as it may take some time. I had prepared drawings for panel manufacturing, but not for submission to the LADBS. I had not made the foundation plan, nor the proper elevation plans. LADBS wants to know what type of finished will be in the interior, exterior, and roof, along with insulation levels.
It took me two weeks to get the complicated drawings prepared, and I hope i can finish the refinement to the plans in three days.
