Services such as kitchen and bath remodeling, window replacement or any project involving cutting, sanding or painting may require special handling of lead paint if present. In a home built before 1978, lead-paint precautions are required if:
- 6 sq. ft. of interior paint will be disturbed
- 20 sq. ft. of exterior paint will be disturbed
Square footage requirements may be less in some states. Home services such as carpet or appliance installation don't typically involve lead paint disturbances.
