As stated in your Lease Agreement,  the apartment is to be professionally cleaned, at tenant's expense, at move-out or vacancy at lease expiration by a Landlord-approved cleaning company.
Please check the website and/or with One Door Realty, Inc for a list of Landlord-approved cleaning companies.
A copy of the paid Landlord-approved cleaning company’s bill is required at the time of move-out. Tenants must schedule well in advance for their apartment to be cleaned to ensure that the apartment is clean prior to move-out.
If a tenant does not have their apartment cleaned by a Landlord-approved cleaning company prior to move-out, Landlord may hire a cleaning company to clean the apartment and the cost of cleaning, plus a $100.00 Coordination Fee, shall be deducted from the tenant’s Security Deposit.
