Would hiding a family be possible today?

Last year I read The Diary of Anne Frank. Wondering how many members would be able to keep in secret 2 families in their home or office? Like in the book supplying: food, clothing and all the other needs. Let's say 8 people for 6 months.
How many could you supply?
Living space (bedrooms, attic, office or warehouse)
Food (3 meals a day)
Money (for all other items)
Secrecy (neighbors, office workers or the government wouldn't see or hear them)
Security (so anyone wouldn't accidentally find them)
