legally you are required to file a TM30 within 24 hours of arriving at your condo or you must file within 24 hours of any other foreigner arriving and staying there.
Realistically if you're only staying for 30 days and don't need to go to the immigration office for anything, you don't need to worry about it. The only time a TM30 is needed is when you're trying to do something with immigration.
