Suspended scaffolds shall be designed by a registered design professional.
Exceptions:
- Design is not required for a single tier nonadjustable suspended scaffold whose platform is 40 square feet (12 192 mm) or less in size.

- The construction of a new building;
- The full demolition of an existing building;
- The vertical or horizontal enlargement of an existing building; or
- The alteration, maintenance, or repair of a façade of a major building where a site safety plan is required by Section 3310.3.
