I am in the process of getting mu subsale vacant house renovated. There will no external renovation, only internal. Therr will be some layout changes including tearing down a few walls and building a few walls internally.
My ID suggested to get renovation permit from MBSA and has suggested a firm to assist with the new layout drawings and submission to MBSA for renovation permit. The firm has asked for documents including CCC.

My question is, would i require to get permit since no external renovation nor amy external extension.
Secondly, I did not get any CCC from the buyer and when I asked him for CCC, he said he didnt get it from the developer. Do I really need CCC from developer to submit CCC to developer?

TIA.
