Then, work with professionals to finalize the site plan. This secures permits. It also prepares the land for construction. This is achieved by running essential utility connections.

This preparation minimizes unexpected challenges during construction. It also minimizes challenges during permitting. Therefore, conduct a soil report if necessary. Also, consult with city experts. Check with them on water meter size, trees, and flood concerns. This groundwork ensures a stable foundation.

Rural Accessory Dwelling Units (ADUs) in Marion County are only permitted in the Acreage Residential (AR) zone. However, the parcel must be greater than two acres in size and meet specific requirements. ADUs are generally not permitted in other rural zones. Specifically, they are prohibited in Exclusive Farm Use (EFU) or Farm-Forest (F-F) zones. Such as:

  1. Located only in the AR zone.
  2. Parcel must be over two acres.
  3. Maximum size is 900 square feet.
  4. Must be within 100 feet of the primary home.

What Should Homeowners Know About Utilities and Fees in Marion?

Water rates often use an inclining structure, so higher usage means a higher rate. Finally, homeowners must be aware of fees for late payments or after-hours reconnections.

For rural ADUs in the Sensitive Groundwater Overlay (SGO) Zone, the ADU must connect to a water storage tank. This ensures compliance with essential infrastructure.
