Residential garages are treated as indoor spaces, while residential parking lots and carports are treated as outdoor spaces. These parking facilities are required to meet either the residential or the nonresidential requirements, depending on what type of building they are associated with.
All lighting attached to the residence or to other buildings on the same lot must be high efficacy. See Table 150.0-A for qualifying high efficacy light sources. Outdoor LED luminaires and LED light sources installed outdoors are automatically classified as high efficacy.
Regardless of the classification of the associated building, residential garages for 8 vehicles or more must comply with all applicable nonresidential indoor lighting requirements in §110.9, §130.1, §130.4, §140.6 and §141.0.
See Nonresidential Compliance Manual Chapter 5 for the nonresidential indoor lighting requirements, and Chapter 6 for the nonresidential outdoor lighting requirements.
Low-rise residential garages for less than 8 vehicles have to comply with requirements of §150.0(k)2I - the lighting to be controlled by occupant or vacancy sensors.
Garages on single-family sites with space for 7 vehicles or less must comply with the residential lighting control requirements in §150.0(k)2I, which require at least one luminaire in each garage to be controlled by an occupant or vacancy sensor.
Garages for 8 vehicles or more must comply with the applicable nonresidential indoor lighting requirements.
For low-rise residential buildings, the associated parking lots and carports with less than 8 vehicles per site must comply with either the applicable nonresidential outdoor lighting requirements or the residential requirements shown on the following table.

Example 6-19: Parking spaces
Question
I have a low-rise multi-family complex with 20 parking spaces. The parking spaces are arranged throughout the site in groups of only four spaces each. Are these spaces required to comply with the nonresidential outdoor lighting requirements?
Answer
Yes, these spaces are required to comply with the nonresidential outdoor lighting standards. Parking lots and carports with 8 or more vehicles per site must meet the nonresidential outdoor lighting requirements, regardless of how the spaces are arranged.
