Restricted CSL: For supervision of construction on two-family dwellings, including accessory buildings and structures.

Unrestricted CSL: For supervision of construction of two-family dwellings, buildings that do not exceed 35,000 sq. ft., agricultural buildings and structures, and walls that measure up to 10 feet.

Specialty CSL: Specialty CSLs fall under an unrestricted CSL, and include such specialty trades as:

• Masonry
• Windows, Doors, and Siding
• Insulation
• Roof Covering
• Solid Fuel Burning Appliances
• Demolition
