A Construction Document is a culmination of all the design and engineering details, both written and graphic. Once you and the architect are comfortable with the design of the house, and that the Planning Department has given the green light to proceed, then the Construction Document is generated. At a minimum this document includes structural drawings, Title 24 energy compliance reports, California Green Building Code requirements, and any other information required by the Jurisdiction Having Authority for permit approval. Building permits have to be applied for before any construction can begin. In order to apply for these permits, there must be a Construction Document.
