If you have given the tenant ample notice that necessary repairs are needed to be done then they can not refuse you or the HOA's entry in to the apartment to do so.  But beware this tenant.  If you enter I can see alll sorts of problems ahead and claims to be made.  So make sure that you or a represetative are there when the repair people are as well to "safeguard" the tenant's belongings.  Good luck.
