How to Apply for an ADU

1. Verify that the property meets the eligibility requirements. 

ADUs are permitted on certain properties.  Below is a list of property requirements defining where ADUs can be built. 

• ADUs are only permitted on R-2 Single- and Two-Family District zoned properties. Search for the zoning of your property here.  
• The R-2 District zoned property can only have one existing single-family dwelling unit on it. 

The owner of the property must occupy either the existing single-family dwelling unit or the proposed ADU as their primary residence.

2. Verify the proposed ADU meets the physical location requirements. 

Read about physical location requirements here (link out to online codified ordinances). 

3. Contact the Planning & Development Department for informal review.  

Residents are encouraged to contact the Planning & Development Department to discuss their proposed ADU prior to preparing construction documents and submitting any applications. City Staff can help provide guidance on the applicable zoning and building code rules and regulations. 

Contact the Planning & Development Department at 216-529-6630.

4. Apply for conditional use permit from Planning Commission. 

Read about the Planning Commission application process here.  

 Some ADU projects may require additional approvals by the Board of Zoning Appeals (BZA) and/or the Board of Building Standards (BBS). Contact the Planning & Development Department to see if your project requires additional approvals.  

5. Apply for approval from the Architectural Board of Review.  

An ADU must be reviewed and approved by the Architectural Board of Review in accordance with any applicable requirements, standards, and guidelines.
