Ocean City New Jersey Rentals

I spent a week in Ocean City New Jersey in a rented house, after the week we had the house was always in the same condition it was before ...

the lease states that the owner has 14 days to give written notification of damage or other reasons for refusing to file

My question is how long the owner must return the security deposit?

The general length of time on an average month to rent month is 10 days, so as an owner, I suppose it would be more than these 10 days.
