Please review Permit Requirements below as they vary from project to project.
Accessory structures include garages and sheds. Up to one structure measuring less than 120 sq ft per property is generally permitted outright and does NOT count towards total lot coverage. If Mechanical, Electrical, or Plumbing (MEP) work is involved OR if the structure is greater than 120 sq. ft., accessory structures also require a Building Permit.
However, Zoning review is required. No Zoning Permit is required if the structure adds less than 10% new floor area to the property. The maximum height is generally 15’. Side and rear yard setback requirements may be waived IF the entire structure is within 35’ of the rear lot line, maximum wall height is 9’ and maximum ceiling height is 12’ at its peak, at least 50% of the rear yard remains open, and no bedroom or full bathroom is included. The setback exception regulations in the Planning Code may be viewed online under OMC 17.108.130, Subsection K.
Once we receive your application and have created it in our system, we will review your plans. If your plans require corrections or if we need further information, we will contact you. For the latest processing estimates, please see our Average Permit Processing Turnaround Times webpage.
