C3-1 Commercial, Manufacturing and Employment District
Commercial, manufacturing and employment uses, intended to buffer manufacturing areas from other districts. Does NOT permit residential dwelling units.
Example on a 50 × 125 ft lot. The dashed box is the maximum zoning envelope, the buildable footprint after setbacks, raised to the 38 ft height limit. The solid building is an illustrative example at FAR 1.2: 1 story covering the full footprint (flush to the lot line, no setback). C3 permits no residential use, so it reads as mid-rise flex-commercial/light-industrial: continuous ribbon windows and spandrel panels, no unit-scale glazing, flush to the lot line rather than apartments over a storefront.

- Parking requirements
- No dwelling-unit parking ratio applies — C3 permits no residential use. Its office/retail/manufacturing uses are instead governed by the Ch. 17-10 non-residential parking table, based on gross floor area and use category rather than a unit count.
Setbacks
- Front yard
- None required, unless the property borders an R-zoned lot — then at least 50% of that lot's front setback. §17-3-0404.
- Side yard
- None required, unless the property borders an R-zoned lot — then that lot's front setback applies.
- Rear yard
- None required — C3 permits no dwelling units, so the 30 ft dwelling-unit trigger never applies.
