Here's the sequence of design review in this portion of Ohio City if I'm not mistaken:
Local Block Block
OCI Design Review (Local Landmarks)
City of Cleveland Landmarks
Planning Commission (if necessary depending on the project)
Board of Zoning Appeals if there's any variances
Submit for Permit Review by Building Department
You typically need to have gotten approval by each sequential review committee for things to go smoothly. You can technically not get approval from block club or OCI, but get approved by City Landmarks but it's very rare. Once the project becomes contentious it really slows down the whole process which is usually the motivating factor for developers. This block club, Franklin Clinton, is run by some real obstructionists, one of them is also on the OCI Design Review Board. Certainly can't submit for permit before Zoning and Landmarks approval. Not sure what "filing" permits means.
