Howard County Zoning Regulations

The Howard County Charter and Code empower the County Council to adopt maps dividing the County into various zoning districts, each of which has certain regulations that govern the development and use of land within the district. The most recent Zoning Regulations were adopted on October 6, 2013 and set forth the uses that are permitted, not permitted or conditioned in each zoning district. Together, the Zoning Maps and Zoning Regulations serve to guide the proper growth and development of the County in accordance with the goals and policies of the General Plan.
