The landlord laws concerning refund of deposit would apply to your situation. So, your landlord will be required to comply with the deposit refund law. Since you are subletting from your roommate, I assume you gave your roommate the deposit directly, correct? Thus you are worried that she might not refund your money.

If you did give your roommate your deposit money directly, it would make her responsible to the same deposit laws as the actual landlord.

I not exactly sure about your state, but in mine this is how the deposit law works:

1) Landlord is required to provide a refund or deposit statement showing how your deposit was charged (within 30 days)
2) You can only be charged for items that are considered BEYOND normal wear and tear

To protect your deposit, it will be impossible for your roommate to sit down with you– not going to happen! So, instead, you will want to document everything. This means that you will want take pictures of your space and show that there is no damage. Be sure to have some reference such as showing in the picture todays paper (to confirm the date of when the pictures were taken) You will want that date reference in all pictures. The date on your camera can be changed to any date, so it isn’t evidence of when the photos were taken.

Picture proof is the best line of defense for you. If your roommate fails to give back your deposit you can then move towards filing a complaint with the RPA or going straight to court.
