The I-L Light Industrial District accommodates a range of light industrial and office uses, as well as limited service uses intended to serve the needs of employees. Light industrial uses are enclosed, low-intensity uses with no external impacts, such as exhaust, noise, glare or vibration.

The I-G General Industrial District is intended to accommodate a range of industrial uses including fabrication and assembly-type manufacturing, as well as office and research and development facilities that may produce moderate external impacts, such as exhaust, noise, glare or vibration. General industrial uses may also contain outdoor storage and related outdoor activities.

The I-MU Industrial Mixed-Use Zoning District accommodates a mixture of light industrial uses and a variety of compatible commercial uses such as entertainment, amusement, and retail establishments, as well as residential uses. District standards are designed to promote the reuse of older, character-giving industrial and warehouse structures that may no longer be suitable for their original purposes, but that can accommodate a variety of alternative types of uses.

Table 6-1: Industrial Districts Dimensional Standards establishes the dimensional standards for the industrial districts. These regulations apply to all uses within each district unless a different standard is listed for a specific use.

For rowhouse dwellings, where the district permits two-family and multi-family dwellings, one or more of the rowhouse buildings in the overall rowhouse development may contain more than one dwelling unit in accordance with the standards in Article 8 for rowhouse dwellings.

Within an existing rowhouse development, one or more rowhouses within the structure may be replaced or reconstructed in accordance with the standards in Article 8 for rowhouse dwellings.

For rowhouse development, where a minimum square footage for lot area and a minimum lot width is indicated, minimum lot area and minimum lot width are calculated cumulatively on the basis of each rowhouse structure within the overall rowhouse development to determine the minimum lot area and minimum lot width for the overall development. The minimum lot area and minimum lot width do not apply to the minimum area or width of the individual rowhouse structure. (See § 315-4.3.D for illustration)

For multi-family development where a minimum square footage for lot area is indicated, the minimum lot area is calculated cumulatively on the basis of the number of dwelling units in the structure to determine the minimum lot area for the overall development. The minimum lot area does not apply to the minimum dwelling unit size of the units within the development.

Table 6-2: IMU District Design Standards establishes the design standards for the I-MU District.

Standards apply to new construction and to expansions that exceed 30% or more of the existing structure's square footage.

The following standards apply to multi-family and nonresidential, including mixed-use, development in the I-MU District. They do not apply to rowhouse dwellings.

See Article 9 for additional on-site development standards and requirements, such as exterior lighting, accessory structures and uses, and permitted encroachments.
