Can the landlord refuse to give me my deposit if there are no damages to the property?

No the landlord cannot wrongfully refuse to return deposit monies. I would issue a stop payment but I do not know the legalities. They can likely sue you but then you can counter-sue.

Under the Security Deposit act the landlord is required to send you written notice of intent to retain the security deposit with an itemization of damages claimed within 30 days after termination of the tenancy. Failure to do so constitutes an agreement that no damages are due and the landlord will remit the deposit immediately. (MCLA 554.610) If landlord fails to provide notice and/or fails to file an action for money damages to retain the security deposit within 45 days after termination, he may not retain any of it and you will, most likely, need to file a small claims action in District Court to recover the security deposit.

Landlord has 21 days after tenant moves out to refund security deposit less amounts legitimately held for damage to property. If they do not your remedy is to sue in small claims for twice the amount of the security deposit as allowed by Civil Code 1950.5.

Check what your lease says about how long the landlord has to return your security first. Then yes, I would seriously consider trying to stop payment if you have real reason to suspect that the landlord is trying to cheat you. It's probably too late, though.

A landlord must provide proof of damage within 30 days of the end of your tenancy to justify keeping your security deposit or else you could win double damages in court.
