Westminster Municipal Code § 17.230.015 Industrial Zoning District Development Standards

This Chapter provides development and land use regulations for the industrial zoning districts established by Section 17.200.010. The purposes of the individual industrial zoning districts and the manner in which they are applied are as follows.

A. M1 (Light Industrial) District. The M1 zoning district provides areas for low-intensity and low-impact industrial, manufacturing, and related uses. Typical uses include research and development facilities and laboratories, small-scale warehouses, and light manufacturing. The M1 zoning district is consistent with the Industrial land use designation of the General Plan.

B. M2 (Medium Industrial) District. The M2 zoning district provides areas suitable for a broad range of manufacturing businesses, wholesaling businesses, and limited warehousing and distribution facilities. The M2 zoning district is consistent with the Industrial land use designation of the General Plan.
