After the plans are approved, DSA is notified by the design professional of the start of construction. DSA reviews the qualifications of and approves the proposed project inspector(s) who will inspect the construction. DSA schedules visits by its field staff to report on the construction and performance of the project inspector to verify compliance with the California Building Code. During these construction site visits, the DSA staff work closely with the project inspector to assure that the intent of the plans and specifications are achieved at the construction site and that all required approvals are properly administered by the design professionals.

The DSA staff reviews and approves all construction change documents, reviews all inspector and lab reports and makes recommendations regarding the closeout and certification of construction. DSA also has authority to stop construction if it does not meet the code. The staff interacts closely and promptly with the design professional to achieve code compliance and to administer construction certification.

In 2013, DSA implemented significant changes to the Construction Oversight Process. These changes are designed to streamline the DSA construction phase process and to ensure that projects are certified at the completion of construction. Effective June 1, 2013, DSA began utilizing an Inspection Card Process similar to that used by virtually every building department throughout the State.
