Not really, for the jalan I do my renovation, there are 5 on-going renovations. DBKL visited frequently. One of my neighbours did not apply the approval and his renovation was stopped and sealed by DBKL twice. Frequently, because of this neighbour's problem, DBKL officers took the "convenenience" to visit my site too.

So, for any renovation involving external renovation, best to apply for DBKL approval. Furthermore, if you don't get the approval, you can't quote the new areas in the SPA. For example, if the old build-up is 2000 sqft and the new area is 2800 sqft, any future SPA can only quote 2000 sqft if there is no approval from the local council.

I will PM you his contact and website.

But, actually, if everything is internal, I don't think you need MBPJ approval. Usually, it is the contractor's Roll-On Roll-Off bin that causes the problem. Your contractor places the bin outside your boundary?
