The Linn County Board of Supervisors has unanimously approved an updated ordinance to change detached accessory structure size limits in residential zoning districts within Linn County following the third and final reading of the ordinance. The new ordinance is effective upon publication in the Gazette, which is expected to happen within the next week.

Detached Accessory Structures

The purpose of accessory structure size limits in residential zoning districts is intended to preserve neighborhood character while balancing rural and agricultural needs. Linn County Planning & Development staff developed the updated ordinance amendments based on an analysis of customer building permit requests for accessory structures over the past 10 years, as well as an examination of best practices.

Changes in the updated ordinance include:

• Size limitations are based on maximum lot coverage and/or structure footprints,

• Size limitations are cumulative

• Maximum lot coverage varies depending on parcel size, with no limit on parcels over 3 acres in size

• Maximum structure footprint is 5,000 square feet

• Maximum height for accessory structures in residential zoning districts is 25 feet

Setbacks

The Linn County Board of Supervisors also unanimously approved an updated ordinance to change property setbacks in several zoning districts within Linn County. The new ordinance became effective Dec. 4.

Zoning property setbacks are regulations that specify the minimum distance required between a building or structure and the property line. The primary purpose of setbacks is to promote safety and privacy for residents while maintaining a consistent visual appearance in each district. Linn County Planning & Development staff developed the updated ordinance amendments using an analysis of zoning best practices.
