hello, everyone. I have the thinking of doing part time in house hair salon, part time only.

I been doing all this while for my friends, colleagues & others, my business is spread by them,
they ask me why not venture out do part time 1st.

my hubby is OK but my mother in-law seems like dont't like it.

do I still need to apply for a license from HDB, DBSS and Executive Condominium Committee ?

please advice ?
