Hi, pls help!

I am staying at usj area, I need to do some minor renovation for my house, as just change the current fencing( since day 1 by developer) into a wall, and also hacking the car porch and do a proper tiling.

Do I need to get approval from Mpsj on this minor renovation? as I know, I do not need any plan since I m not disturbing the main structure of the house.

How about the waste generated?

Any contractor out there can recommend to settle the solid waste?

Thanks. Will go and ask around! I think I m not going to apply any permit o watever, just start next week and Kao dim it!
