There is no specific size required however, it must be clear from the plans what work is being done and how it is being done. Plans should be to scale and legible. A title block giving the address of the project must be provided on all sheets. All areas addressed in the building code must be addressed on the plans. In general, plans for new construction should include floor plans, foundation plan, framing plans, sections and elevations. Simply adding a note to the plans that says "all work to comply with codes" is not sufficient. Remember--we can only review what is submitted to us. Therefore, the more complete that the plans are, the less likely that any problems will arise after construction.
