6.7 Additions and Alterations

Additions are consider newly constructed buildings, so they must meet the applicable residential lighting requirements of §150.0(k). 

For alterations, existing luminaires may stay in place but any new permanently installed luminaires shall meet the requirements of §150.0(k).

Residential building additions must meet all mandatory requirements in §150.0. Because the residential lighting requirements are mandatory, lighting in all residential building additions must meet the requirements outlined in this chapter.

For residential building alterations, any new or altered lighting systems must also meet all the requirements in this chapter. Existing luminaires and lighting systems that are not altered may stay as is. Use JA8 compliant trim kits or JA8 compliant lamps to alter existing screw-based ceiling recessed luminaires to be code-compliant.
